Introduction
First of all, Credits and thanks to BPower, Dirac, and Vexorian for their missile systems at which I based this system upon, and to AGD for the help with effect orientation methods.
This is a Missile system that I put together initially to fulfill my resources needs. Very often while I was creating system, spells and maps I found myself in need of a such systems, but all the available options usually have a little flaw that forced me to used something else.
For example, let's say I wanted a missile that can arc and homing to a target, well there goes BPower's system. It can arc/curve but can't do homing with arc/curve natively. So the options left are Vexorian xemissile which can arc and do homing but cant curve, and Dirac's Missile system. Then again more problems with those, because Vexorian system do not have a lot of the useful events like Dirac's and BPower's systems. Dirac's system can arc/curve and do homing but it's T32 timer is never stopped and it do not have some useful events that the BPower system has. So I decided to get all three system together and build my own system with the stuff I think is useful and with the syntax I think is the most friendly, because I'm not a genius of vJASS myself.
What's different in this system?
Ok, so why it's called "Relativistic Missiles"? Well because mid development I realize that the way missiles were being processed could be optimized and the Einstein postulates about Time Dilation by Gravity gave the idea behind the implementation. Yeah, I know, WTH?
When it comes to Missile systems, performance is everything, and all missiles systems do basically the same thing when processing missiles instances, they loop every set period, which is usually 1/32, through all instances and do their calculations and event calls. The problem with it, is that the more instances existing at a given moment the greater will be the tanking of the game frame rate because the game will lower its fps so all that's need to be done before the next frame gets drawn have time to do so, and that's where the Einstein postulates gave me an idea.
See, when we study Relativity, we learn that gravity dilates time, the greater the gravitational potential (more or less mass) the slower time passes relative to an outside point of reference. Gravity in this analogy would be the amount of missiles instances currently existing, so instead of letting the game frame rate drops drastically to move all those instances, I make the missile instances have their time dilated.
Ok, but how?? Simple, first we need to find what I'll be calling the system Sweet Spot, which is the amount of missiles the game can handle without dropping to much performance per given period, which I found out to be between 150 and 200 missiles. Then we limit the amount of missiles processed per period to this sweet spot, and move the next missile in the line to be processed and all other behind it to the front, In terms of data structures, think of a circular list with a head and tail, and we move the head and tail to change the initial and final positions. I did it with arrays because they are a bit faster and because I'm lazy .
But that's not all, because by limiting the amount of missiles processed, we delay their next process call by (total amount)/(sweet spot), so now their speed needs to be corrected and relativity comes full circle now, because time dilation has it's relation with Length Contraction, so we increment the missiles speed by this factor.
Also, something very important is that this system is using only effects as missiles, thanks to the new natives introduced in 1.31, so no dummy units, no CreateUnit() and SetUnitFacing() blasphemy. I've included in the test map a version of this system that do use the dummy method for those that do not have the newer versions of the game. I Also included a version of this system that uses the usual process method, so processing all missiles in a single blow.
Results
I've taken the liberty to test this system against the king of Missile systems for some time, BPower's System. Below, there are 3 videos I make for stress test. The first from the left is BPower's Missile System reworked by AGD. Amazing job btw. You will be able to notice what I was talking about earlier about the sweet spot, when there are more than 150 or so missiles being processed, the fps goes basically to 0 and it freezes until the missiles are finished.
The video in the middle is my system in its normal version (not relativistic). It performs a little better (I've build it a little differently), but in the same way, when the missile count near 250, the fps starts to go down hill real quick.
The video in the right is the relativistic version, notice the missile count and fps compared to the 2 other system. At about 600 missiles fps get really low, but not so much because of the amount of missiles being processed but because of the amount of visual effects in the screen. If the screen was moved to the side where not so many stuff is visible, fps goes up. In my internal tests I was reaching more than 1200 missiles with about 16 fps but with no screen freezes.
And Last but not Least, a video with the examples.

(v1.0)
Release
(v1.1)
Merged Normal and Relativistic code for both Legacy and Current versions.
You can use the SWEET_SPOT constant to determine the system behavior
SWEET_SPOT <= 0 -> normal method
SWEET_SPOT > 0 -> relativistic method
Included support for DummyRecycler by Flux for the Legacy version. This should improve its performance even further.
(v1.2)
Fixed a bug for homing missiles height
New configuration member boolean collideZ -> set to true to make the new missile consider z collisions
New Global Configuration constant boolean ROLL -> If true missile will consider roll in orientation. Roll can look really fishy for some users and was never possible until patch 1.31, so if you want it set it to true in the globlas block (1.31+ version only).
You can now attach effects to the main missile effect with an offset through 2 new methods (1.31+ version only)
// dx, dy, and dz are offsets from the main missile coordinates
method attach takes string model, real dx, real dy, real dz, real scale returns effect
WorldBounds now is required (Centralized requirements and outsourced)
New optional event (See Available Events for more info)
method onBoundaries takes nothing returns boolean
Fixed a spelling mistake on the detach functionality.
(v1.6)
MissileEffect library updated to use the BlzSetSpecialEffectOrientation native. (v1.31+ only)
(v1.7)
Standardized getting and setting of the members speed, arc and curve. They now read and write in degrees.
(v1.8)
Made a system function (GetLocZ) private to avoid conflict with other resources.
(v1.9)
System ported to LUA (Credits to Forsakn for the first port).
Added instant facing when creating missiles instances.
Included a version of Missiles that uses the dummy method and a Dummy Pool utilizing the new natives. This version by default will not let missiles clip through terrain.
Code formatting and cleaning.
(v2.0)
System ported to GUI!
Implemented ways to enumerate missiles (Missile Groups)
New method: pause. When called pauses or unpauses the missile
2 new events: onPause and onResume
3 new members: roll, type and paused
Added the attach and detach methods to the LUA version
Fixed a bug on the collideZ
Fixed a bug when deflecting missiles
Refactored code to be more readable and easy to maintain
(v2.1)
Removed the usage of a post 1.30 native being used in the 1.30 version of the system. Now the 1.30- version should work for patches below that
Fixed a bug in the LUA GUI version for the onPause and the onRemove events
Added an alternative method of setting up events for the GUI version. It's more compact, you can set up all events you want inside only 1 trigger (See the Trigger Preview for examples on how to do it)
(v2.2)
Adjusted the initial position of the missile in the versions that use the dummy method.
(v2.3)
2 new events:
onCliff -> Run whenever the missiles collides with a cliff wall and it's height is greater than the current missile height
onTileset -> Run whenever the missile changes terrain types
4 new members
nextX -> The next missile x value
nextY -> The next missile y value
nextZ -> The next missile z value
tileset -> the current terrain type under the missile
Fixed the missile movement on higher ground levels
Fixed the movement of missiles when going over terrain/cliffs for the dummy versions
Separated the GUI version into vJASS and LUA implementations. For those who want to choose between them.
(v2.4)
Missiles can now grant vision using the new member "vision"
vJASS:
// To set (The missile must have a source or a owner)
yourMissile.vision = value
// To get
var = yourMissile.vision
Lua:
-- To set (The missile must have a source or a owner)
yourMissile:vision(value)
-- To get
var = yoruMissile.Vision
Example
Actions
-- Set the MissileVision variable before running the MissileCreate trigger ou at any event trigger (The missile must have a source or a owner) --
Set VariableSet MissileSource = (Triggering unit)
Set VariableSet MissileVision = 800.00
Creates the missile
Trigger - Run MissileCreate <gen> (ignoring conditions)
New required library: Alloc
Fixed a few bugs in the GUI version
(v2.5)
Missiles can now be paused within the onFinish event.
Removed the deflectZ method, now the deflect method expects x, y and z parameters
New method deflectTarget deflects the missile to a unit
New GUI variable MissileData can be used to store information as needed (integer type)
version 1.31+ non dummy only changes:
4 new method operator (operators in vJASS, functions in Lua)

I have a few issues with your API. It's great don't get me wrong, but a few things made me implement my own method instead of just using yours. First, like JAKEZINC said is the orientation problem, it produces wrong results with the method i implemented. I did suggested it in the thread for you to add a orientation method that would use the direct yaw, pitch and roll alongside the one already there, but you didn't add it. Second is ease of use, as i said i wanted this system to be as friendly as possible to entry level users, and your system, although very sophisticated, looks somewhat scary, specially for those who never seen a struct or are just beginning to learn it. I also think it could be more intuitive to use, for example, in my own, although very simple, method names are straight to the point, "attach", "detach" and effects are matched by handle instead of by model name, which is also a downside since your system only allows for 1 model of a type. Finally i wanted it to be as lightweight as possible, and when the user wanted a more sophisticated functionality he/she could implement him/herself for a specific missile.
method attach takes string fxpath, real dx, real dy, real dz, real scale returns effect
method dettach takes effect sfx returns nothing
method orient takes real yaw, real pitch, real roll returns nothing
method move takes real x, real y, real z returns nothing
method scale takes effect sfx, real scale returns nothing
/*
If it's only meant to scale a single effect handle the user can simply do this with a native call
*/
...
equivalents in mine:
JASS:
method addModel takes string model returns effect
method removeModel takes string model returns nothing
method setOrientation takes real yaw, real pitch, real roll returns nothing
method move takes real x, real y, real z returns nothing
call BlzSetSpecialEffectScale(sfx.addModel(model), scale)
// Equivalent of my scaling to yours
...
Looking at the above, I honestly don't see what makes the later one scarier over the former. I find both names 'to the point'. And regarding the ease of use, I can argue that it's easier for user to just specify the model both when attaching and removing attachments than to also specify position offsets when attaching an then having to save it to an effect variable just so you can dettach it. Note that multiple similar models being attached is the rare case rather than the norm, so if I were to appeal to ease of use for majority of users, I'd still go with the later API.
Now the point that I want to get across is not which API here is 'truly' better because honestly, it can be very subjective. Even me when looking at already established resources, I can find a lot of them where I want to recreate their APIs into something 'I think' (the keyword there) is better and more intuitive. But then again, idea coming from me would ofcourse be intuitive to me. That's why I refrained from mentioning API initially in my comments since it is very subjective and instead emphasized the result which would be redundancy of resources from the user's side when importing.
As for the use of lite-ness as a reason for reimplementation, one can also use this for most of the resources here in Hive actually, such as damage systems, unit indexers, etc., to make lite-variants of those various systems. But I don't think it would be good practice.
Regarding the orientation, it didn't made a difference in my tests (JAKEZINC also said it didn't). But since you emphasized it and since both of us haven't tested it in Reforged, I think I'll change it to be safe.
private modules are working correctly? I remember some time ago they were not, i will add the private to them so it will not conflict with external libs.

All fair points, but i still think providing the ability to create multiple effects of the same type is a good addition as well as enabling offsets to them even if its not the normal case, and if someone can save a string to remove a model later they can save an effect just as well. I don't think my version is better than your, on the contrary, but it's the way i found to deal with the problem and it performs well. I don't think you should change stuff on your code (orientation) just to accommodate a difference in my system, since I've already created something of my own and don't intend in rewriting a lot of code.
I've found out how to tie this system very rudimentary to GUI, which is what I'm most comfortable/familiar with. One thing that I'm not able to solve though, and I feel silly for it: using the Q example (Firebolt) I've been trying to figure out how to get it to travel towards the targeted area for a set distance. (As it is now, if you fire a Firebolt right next to your Hero the bolt is destroyed. I'd like to know how to set the minimum/maximum distance to 600 towards the cast point, for example.)
I'm not familiar at all with JASS; honestly. That's probably why I'm struggling. I tried converting some GUI into JASS hoping to jury rig something together, but I wasn't successful. Could you provide any tips?
^ Before converting a GUI script into JASS, make sure to understand the basics of JASS first.
Once that script gets converted, it would only show you some toppings such as BJs and implicit
boolean operations which aren't that complicated once you get to learn the basics honestly.
@chopinski , can you show a GIF or similar showing a case where BlzSetSpecialEffectOrientation() yields incorrect results compared to BlzSetSpecialEffectYaw/Pitch/Roll()? So I can test it also myself because so far there has been no difference except for the one below, which shows that the later method actually has problems.
You will see in the gif that the later method sometimes causes flickering when the pitch is at 90 degrees (facing down) or at 270 degrees (facing up). It also moves the effects up and down a bit. On the other hand, effects remain steady when using BlzSetSpecialEffectOrientation().

@AGD I've tested the orientation native in my missile system and in a few of my Hero Concepts and apparently Blizzard have patched the native because now it produces the exact same result as in using the Yaw, Pitch and Roll natives, at least for the orientation method i implemented (Dirac's method), even with no roll (in my system its optional). I remember it being an issue when i reported it here but now it seems to be solved, which is good, because your SpecialEffect Lib do not need to have any change now. I'll change my MissileEffect lib to use the native as well since its less lines of code. I cant say at which version they change it, but I tested it in reforged as well and they are producing the same result.
It looks like they do fixings like these without mentioning in the patch notes. -,-
I mean if they did fixed something that's troublesome for us before they should inform at least. (whether it's a minor or major thing)
As it could help us to point and revert the changes we've made just to workaround with these and to avoid such confusions like this.
There are even some of the reported broken natives that weren't broken before and can crash a game.
I believe these are worth of mentioning in the patch changelog list.
Regardless, it's good to know that these orientation natives are now fixed in the latest patch though. This just implies they do listen.
(I just don't like their idea of being implicit when it comes to these things, they should speak somehow to fulfill good communication)

Fully agreed, and it seems that they are leaving The World Editor/ Jass changes in the dark, so we must find out whats different ourselves, which sucks, because those were not the only changes to happen to jass in the latest patches.
Sorry for the delay response. Hold your horses for a bit longer, things are a bit chaotic here right now, but as soon as i can i'll do what you asked. As a spoiler, the performance will not be much different, specially if you use the dummy recycler library. If you go to page 2 of this thread and look for a video i posted in response for IcemanBo comment you will be able to see the Barrage spell that has onHit and onDestructible events and still are able to run with thousands of missiles without breaking the game.
Edit: @Dat-C3 Below is a simple spell like you asked. I also attached a test map. What the spell do is when you cast it, from the position of the caster every 0.05 seconds a fire ball will be launched to you current mouse position. The missile has only an onHit declared.
JASS:
scope Example
// The following Spell struct represents our missile.
// To make it behave like a Missile just make it extend Missiles.
// After that you will be able to optionally declare any event implemented.
private struct Spell extends Missiles
// the onHit event is one of the events that you can
// implement. You must declare it like this.
// It will only happen if your missile has a collision
// size greater than 0.
// To see how and what events you can implement and
// what they do see the Events section in the thread.
method onHit takes unit hit returns boolean
// owner, source and damage are all members of the main missile system
// that you can set when creating it. To see what members you can have access
// see the Members section of the thread. That's it, now your missile will do
// damage to any enemy unit within it's collision size
if IsUnitEnemy(hit, owner) then
call UnitDamageTarget(source, hit, damage, false, false, ATTACK_TYPE_NORMAL, DAMAGE_TYPE_MAGIC, null)
endif
// returning true will destroy the missile.
return false
endmethod
endstruct

I tried to detail every piece of the code so you can understand whats going on. It's also using the version that uses the dummy method. Good Luck!
this is pretty wicked, im new to the whole jass thing, so heres my question, how would i make it so it is doing that damage only to the enemyunits, currently it is damaging everything, my own buildings and units and allies buildings and units, its probably very simple and i am just missing something lol any help would be greatly appreciated

Why don't you post your code here so i can guide you through it. To filter enemy units you can use native IsUnitEnemy takes unit whichUnit, player whichPlayer returns boolean inside a onHit event.
well im playing with the missilesW on your map, damaging instead of straight killing, so as it would be in there how would i put it and where exactly lol
updated: hah i figured it out now, i was forgetting to set the owner of dummy lol geez, this missile system is great much fun

I cant see any leaks in an initial look at your code, but i'm pretty sure there are ways to optimize it. why dont you post what you want your ability to do so i can give you some tips.
Basically I'm trying to re-create rain of fire/blizzard but without the need for channeling and with an arbitrary projectile model. Its different then the sample spell in the sense that there is a wave of projectiles and then a short delay, and then another wave and short delay until a certain wave count is reached.

@KitsuneTailsPrower here is the Rain of Fire ability but more optimized. I commented a lot so you can follow along and understand where you messed up a little. For this spell i made it so that missiles would spawn from the same x and y position like in the original rain of fire, but if you want them to be angled like in the example you can use the method you are using to displace the missile spawn position from the impact position.

Also, take a look at my Mannoroth Hero Concept, there i implemeted a version of rain of fire as well. It's easy to import and to configure.
This will be very useful thanks. I think that you made the damage aoe be centered on each missile's coordinates but I wanted it to be centered on the target point of the ability hence why I had the RoX_X and RoX_Y struct members but this is a big help anyway ( :
Sorry for the delay response. Hold your horses for a bit longer, things are a bit chaotic here right now, but as soon as i can i'll do what you asked. As a spoiler, the performance will not be much different, specially if you use the dummy recycler library. If you go to page 2 of this thread and look for a video i posted in response for IcemanBo comment you will be able to see the Barrage spell that has onHit and onDestructible events and still are able to run with thousands of missiles without breaking the game.
Edit: @Dat-C3 Below is a simple spell like you asked. I also attached a test map. What the spell do is when you cast it, from the position of the caster every 0.05 seconds a fire ball will be launched to you current mouse position. The missile has only an onHit declared.
JASS:
scope Example
// The following Spell struct represents our missile.
// To make it behave like a Missile just make it extend Missiles.
// After that you will be able to optionally declare any event implemented.
private struct Spell extends Missiles
// the onHit event is one of the events that you can
// implement. You must declare it like this.
// It will only happen if your missile has a collision
// size greater than 0.
// To see how and what events you can implement and
// what they do see the Events section in the thread.
method onHit takes unit hit returns boolean
// owner, source and damage are all members of the main missile system
// that you can set when creating it. To see what members you can have access
// see the Members section of the thread. That's it, now your missile will do
// damage to any enemy unit within it's collision size
if IsUnitEnemy(hit, owner) then
call UnitDamageTarget(source, hit, damage, false, false, ATTACK_TYPE_NORMAL, DAMAGE_TYPE_MAGIC, null)
endif
// returning true will destroy the missile.
return false

I tried to detail every piece of the code so you can understand whats going on. It's also using the version that uses the dummy method. Good Luck!
testmap failed to work b/c I am unable to reforged, however I was able to copy and paste it all. This is pretty cool and a nice limit of 4100 for a 3D system. The jumping/lagging projectiles on the other hand, do they skip over area's?

The dilation of projectiles movement is proportional to the amount of current active projectiles, so if you want less "jumping/lagging" you can increase the "SWEET_SPOT" amount int he configuration block, but be aware that it may cause more performance impact by doing so, tho i doubt you will be able to create that many projectiles at any given time.

Hi Chopinski, I'm trying to adjust your W spell to:
Have damage per ability level
Deal damage to enemy units which are alive / non-structures / non-magic immune
I tried to include what you wrote in a previous answer, but the "MAGICIMMUNE" is leading to errors. Also, for some reason the caster is doing damage on himself, even though I added the "IsUnitEnemy".
Can you please help adjust it?

But with the added damage I noticed that even low damage is enough to kill a high HP unit if this unit is standing next to the caster (as almost every single fireball will for sure connect).
So sorry some further descriptions:
The damage instance should only happen when an enemy unit is within the impact area of a missile, not while the missile is in the air (kinda like cluster rockets, but with a lot more control over the collision area within the AoE selection.)
(BONUS if possible) Can this ability be channeled and only continue while the hero keeps channeling? In your Mannoroth Hero concept the Fire Rain spell is cast once and missiles keep coming down. But I was thinking that this W spell makes more sense as channeling ability which can be interrupted (as the the hero can just move around while the missiles keep coming if it takes a long time for all missiles to be fired)

But with the added damage I noticed that the enemies get damaged on each timer instance instead of once. So basically even 10 damage is enough to kill a 500 HP unit if the fireball goes through the unit. Another thing I noticed is that enemies get damaged outside of the selected ability radius instead of only around the place where the missile impacts. I thought I could fix this via
JASS:
method onHit
return true
...but this would probably only fix that units get damaged several times, not that they get damaged outside of the ability selection radius.
So sorry some further descriptions:
The damage should only be dealt 1x to an enemy unit. And not when "touching" it while the missile is in the air, but only if the enemy is within the impact area of the missile. So several units can be hit by 1 missile if they are within the impact area of a missile, but not again after they were damaged by this missile (on impact the missile would be destroyed anyhow)
(BONUS if possible) Can this ability be channeled and only continue while the hero keeps channeling? In your Mannoroth Hero concept the Fire Rain spell is cast once and missiles keep coming down.

onHit is only called once per unit collision by default, so it's not the system fault. Probably some other trigger is being called (Damage Systems) when you do damage. Each missile only enumerates units within it's collision range, so you eaither have multiple missiles passing through the same unit or there's something else aside from the this piece of code doing it.
Returning true inside a method will cause the missile instance to be destroyed because this is the main form of terminating a missile. Check other triggers, specially those that use on damage events. I suggest you implement this ability i a map alone to guarantee that it is not this piece of code doing it.
You are right, sorry. Apparently it's because so many fireballs go through a unit that even a unit with high HP dies from all the small damage instances, NOT because a fireball deals damage several times. Adjusted the above post.
Would the above adjustments still be possible though? Otherwise a unit standing right in front of the caster gets destroyed too easily...
This seems really cool, but the Systems spoiler seem to contain version 1.5, not the latest 1.6, and I'm a silly 1.31.1 user, so I can't use the sample map.
Can you please update the Systems-spoiler?
(Will probably start experimenting meanwhile)
I have a problem with this system right now. It does not respect the "onFinish" return false, to keep the missile alive.
So the ability I'm working on is the Plasma Grenade from the Halo games.
I throw a grenade, after X seconds, it explodes. If I hit a unit, it "attaches" to the unit.
Note that it might just lay there on the floor
The problem is that this part of the system code is messing with me.
What is the point of this code? Because from my point of view, it's making the documentation lie...
(I'm ofc taling about the line pointed out with "<--")
Does it have strange side-effects if removed?

The code you pointed out is there to allow the onFinish event to be able to call the deflect method. You are using the missile instance in a way you should not. Im not home right now but when i get there i will build an example of how should be a better way to do it. Basically you should separate the missile from its explosion component. Launch the missile if it hits an unit call a method from another struct that represents the delayed explosion, or if it reaches its end, then on the onFinish event you call that same method to explode on that location instead
Returning false onFinish does not mean keeping the missile alive, it means that you will delegate to the missiles system to remove the missile in its natural order, on the onRemove event. Returning false on the onFinish will only keep the missile alive if you deflect it, else its end destination do not change and it will end
Basically you should separate the missile from its explosion component. Launch the missile if it hits an unit call a method from another struct that represents the delayed explosion, or if it reaches its end, then on the onFinish event you call that same method to explode on that location instead
I'm very new to vJass, but experienced programmer. I have 2 classes atm, one Missile and one Controller (that handles the explotion, damage, etc)
I had issues communicating out from the Missile to the Controller, therefore I let the Missile be the "data holder" for the "main controller". I want the explosion after 2.5 (the ability is WIP, this number is not set in stone!) seconds, regardless of hit or finished, and therefore wanted it to be kept alive until the explosion had occurred.
Note that I want the grenade to "bounce" if it has enough speed left (possibly many times) at "target point" (this is done in "onFinish" I guess) and then stay on the ground (preferably without a new birth animation on the effect!).
I'd appreciate any help
I guess that I was doing something wrong, but I also thought that I was doing things according to what was in documentation.
Edit:
I find it a bit confusing that you get Radians when using the "arc" operator, but you have to set it using degrees. Maybe keep the units the same for that operator?
Also: The "get speed" operator gives "speeds per period", but the set speed is "speed per second"

Mostly you are, i think you just misuse the onFinish event that's all., that's why i want you to give me a description of what you want your spell to do, so i can create something that is either what you want or similar for you to follow.
Edit:
I find it a bit confusing that you get Radians when using the "arc" operator, but you have to set it using degrees. Maybe keep the units the same for that operator?

Master Chief throws a Plasma Grenade towards target location that will explode after 2.5 seconds. (A fixed timer, regardless of what's happening! The exact time will need to be tested on what looks/feels good)
If the grenade hits a unit during the throw, it will stick to it. The grenade might bounce once at the target location (details here is "however it feels/looks good") traveling slightly further than target location before laying still on the ground (if it doesn't hit any unit) where it will remain until it explodes.
Units within X radius takes double damage, enemies further away than Y radius takes half damage.
Deals A + (B % of <stat>) damage.
Deals friendly fire! (But not to friendly buildings!).
--
Edit:
Honestly, the code I posted last works if I remove the terminate call that I disliked.
I can deflect in "onFinish" without that "terminate" and it gives control over the termination to me (as I like it).
Also veloc is used internally, speed is only used externally, so I'll, in my map, edit the "method operatior speed" to return "veloc / PERIOD". It is safe to do so and it behaves as I'd like it to.
Although I point at things I call flaws, this system is really great! Thanks!
It's really easy to make abilities nice and readable within this system while keeping good performance.
And I don't have to do the math for arcs and curves

That else block is there in case you deflect the missile inside an onFinish event and don't return true in it. You can see the effect in the system test map for the MIssiles - D ability (the phoenix one). If you comment out the else block like you did and cast that ability, the missile will continue to exists and leak, that's why i included it. I will standardize the getting and setting of speed, arc and curve because it makes more sense for the user.

Well, if you'd return "deflected"-variable instead of "false" in the "onFinish" for the Phoenix ability, you'd destroy it, even without that line in the system.
Imho that's a safety-net that hinders abilities that want to control the life of the projectile (something I want to do for my PlasmaGrenade-ability).

EDIT: Oops, you cannot just return deflected. You need to do something like:
JASS:
method onFinish takes nothing returns boolean
if deflected then
return true
else
set deflected = true
call deflect(GetUnitX(source), GetUnitY(source))
return false
endif
endmethod
But my points is that it's handlable from ability and not needed from the system.
Well, if you'd return "deflected"-variable instead of "false" in the "onFinish" for the Phoenix ability, you'd destroy it, even without that line in the system.

That works if the user know exactly what he/she is doing, but for more entry level users that are just learning vJass they might forget it and cause a lot of leaks in their games, which is not good. You're right, it's a safety-net that if it's not there has potential to be very detrimental to the game-play. As a programmer you would understand that some system sacrifice some freedom in exchange for safety, specially if it has a chance to be a system breaking thing.

@ThompZon here's a version of your spell i made. It's incomplete with a few basic things that you can add yourself, but the main idea behind what i was talking earlier is there. I also attached a test map.

The fact that most of these spell you can spam fire without too much lag is nice. Not much use in normal maps, but I can see DBZ map making use of this many particles at once haha.

Only if it wasn't in vjass, a lot of the epic systems fail to get used b/c of being in a syntax other then jass/gui or lacking an interface for jass/gui.
It's possible but it has nothing to do with the Missiles system, you would only need to create a trigger that would fire when a unit stops channeling an ability and then stop missiles from being created.

Which part has nothing to do with the Missiles system?
The damage within the missile impact area only (and not while the missile is in the air) is to prevent massive damage when enemies stand near the origin point, as basically 50+ missiles would go through the enemy.
And the channeling part is because I don't know how to make the JASS system "Interact" with a GUI system. I know how to recognize the start and end of a channel in GUI, but not how I can stop the Missile system from firing when an interrupt happens...

To do all that you would need to have a basic understanding of JASS. Basically to not allow a unit to be damaged by all missiles you could use a flag and check the distance between the caster and the hitted unit. To stop missiles from being created when you unit stopped channeling is very basic using events, but again you need to learn JASS. But here is the thing, why would you not want a unit to not be damaged by all missiles if it is to close? If something stay if the face of a barrage deserves to be destroyed.

Well xD Good point, but to me it seems unbalanced that a melee unit (which usually is at a disadvantage to range units anyways) is annihilated by 1 click after finally getting close to the nasty range unit. I want this range caster to be very strong at a distance, but WHEN a melee finally gets close, the range caster is more or less screwed.
Anyway to launch units with this system or can only launch Misile we create? Thanks! Works great, but also looking to use this as a jump system of some sort as well =)
However, I kinda want to be able to make projectiles that travel with a from {x1,y1,70} to {x2,y2,70} with a fixed distance to the ground (similar to basic war3 spells).
My first though was with a linear offset on Z, so {x1,y1,1} to {x2,y2,99} would travel 1 -> 99 on Z linearly with the 1 -> 99 being the offset to LocZ, but I don't really need that atm, just anything with fixed distance to LocZ.
Is it possible?
Currently projectiles clip though terrain, and I want some to behave more like classic War3 projectiles
