Hello Hive!
This is a Missile system that I've put together based on Vexorian , BPower and Dirac Missiles System, so Full credits to them. Also thanks to AGD for the tips and ideas to solve some problems.
Why?
- Well, recently I've been coding quite a bit of resources and the stuff that i was creating usually required a missile system, but all those system usually have a little flaw that forced me to use something else in order to achieve what i wanted.
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, 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 timer is never stopped and it do not have some useful events that the BPwer 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.
Since i based this system on their job, full credits to them.
There are 2 versions of this system. The first is for versions 1.30.x and lower. This version uses the dummy method. The second version is for patch 1.31+ and uses the new natives to manipulate effects, so no dummy, only effects.

(call)
method bounce takes nothing returns nothing
- Bounces the missile from its current Z position.
- Useful when assigning targets to missiles that were
- already active, it fixes the rough Z position change.
(call)
method flush takes widget w returns nothing
- call this method to allow the missile to be able to hit
- a unit or destructable again

library Missiles requires optional WorldBounds
/* ----------------------- Missiles v1.0 by Chopinski ----------------------- */
// Thanks and Full Credits to BPower, Dirac and Vexorian for the Missile Library's at which i based
// this Missiles library. Credits to Vexorian for the dummy model.
// How to Import:
// 1 -First copy the Missile dummy unit into your map and then import the dummy.mdx
// model, setting the missile dummy model path to imported dummy.mdx model.
// Dummy model: https://www.hiveworkshop.com/threads/vexorians-dummy-model.149230/
// WorldBounds: https://raw.githubusercontent.com/nestharus/JASS/master/jass/Systems/WorldBounds/script.j
// 2 - Copy this library into your map and set the
// DUMMY_RAW_CODE to the raw code of the missile dummy (ctrl + d) and you
// are done
// How to Use:
// This system works almost identicaly to the Missile library by BPower but
// with a more user friendly interface in my opinion. Also this system
// allows you to create Arc/Curved Homing missiles like Dirac's system.
// Differently than both BPower and Dirac systems, you are not required
// to use the ImplementStruct at the end of your struct. To make your struct
// behave like a Missile simply make it extends Missiles and you are done.
// After that you will have access to the events in the MissileEvents Interface.
// Simply declare the event you want for your strcut to have and the system
// takes care of the rest. You can access the members and functions using
// the "this" or "." syntax which is a plus. to terminate a missile, simply
// return true or call terminate() within the method. Example:
// struct MySpell extends Missiles
// method onPeriod takes nothing returns boolean
// // will display the missile current position
// call ClearTextMessages()
// call BJDebugMsg(I2S(.x))
// call BJDebugMsg(I2S(.y))
// call BJDebugMsg(I2S(.z))
// return false
// endmethod
// endstruct
// function Spell takes nothing returns nothing
// // the create method takes the initial and the final coordinates
// // if the target member is set, the missile home
// local MySpell spell = MySpell.create(fromX, fromY, fromZ, toX, toY, toZ)
// set spell.source = GetTriggerUnit()
// set spell.target = GetSpellTargetUnit() -> when a target is specified the missile will be homing
// set spell.speed = 1000 -> warcraft 3 speed unit
// set spell.duration = 1.5 -> will set the speed to match the time passed
// set spell.model = "Some Model.dmx"
// set spell.scale = 1.3
// set spell.arc = 30 (degrees converted to radians internally)
// set spell.curve = GetRandomReal(-40, 40) (degrees converted to radians internally
// call spell.launch()

JASS:
library Missiles requires optional WorldBounds
/* ----------------------- Missiles v1.0 by Chopinski ----------------------- */
// Thanks and Full Credits to BPower, Dirac and Vexorian for the Missile Library's at which i based
// this Missiles library. Credits and thanks to AGD and for the effect orientation ideas.
// This version of Missiles requires patch 1.31+
// How to Import:
// 1 - Copy this library into your map and optionally WorldBounds
// WorldBounds: https://raw.githubusercontent.com/nestharus/JASS/master/jass/Systems/WorldBounds/script.j
// How to Use:
// This system works almost identicaly to the Missile library by BPower but
// with a more user friendly interface in my opinion. Also this system
// allows you to create Arc/Curved Homing missiles like Dirac's system.
// Differently than both BPower and Dirac systems, you are not required
// to use the ImplementStruct at the end of your struct. To make your struct
// behave like a Missile simply make it extends Missiles and you are done.
// After that you will have access to the events in the MissileEvents Interface.
// Simply declare the event you want for your strcut to have and the system
// takes care of the rest. You can access the members and functions using
// the "this" or "." syntax which is a plus. to terminate a missile, simply
// return true or call terminate() within the method. Example:
// struct MySpell extends Missiles
// method onPeriod takes nothing returns boolean
// // will display the missile current position
// call ClearTextMessages()
// call BJDebugMsg(I2S(.x))
// call BJDebugMsg(I2S(.y))
// call BJDebugMsg(I2S(.z))
// return false
// endmethod
// endstruct
// function Spell takes nothing returns nothing
// // the create method takes the initial and the final coordinates
// // if the target member is set, the missile home
// local MySpell spell = MySpell.create(fromX, fromY, fromZ, toX, toY, toZ)
// set spell.source = GetTriggerUnit()
// set spell.target = GetSpellTargetUnit() -> when a target is specified the missile will be homing
// set spell.speed = 1000 -> warcraft 3 speed unit
// set spell.duration = 1.5 -> will set the speed to match the time passed
// set spell.model = "Some Model.dmx"
// set spell.scale = 1.3
// set spell.arc = 30 (degrees converted to radians internally)
// set spell.curve = GetRandomReal(-40, 40) (degrees converted to radians internally
// call spell.launch()
// endfunction
// Available members and methods:
// Coordinates impact -> the impact coordiantes (x, y, z, anngle, slope, alpha, distance)
// Coordinates origin -> same, but for origin
// //-------------------------------------------------------
// readonly real x -> current x position of the missile
// readonly real y -> current y position of the missile
// readonly real z -> current z position of the missile
// readonly real prevX -> last x position of the missile
// readonly real prevY -> last y position of the missile
// readonly real prevZ -> last z position of the missile
// readonly real height -> the arc of the missile (change it using the .arc operator)
// readonly real turn -> the turn rate of the missile
// readonly real open -> the curvature of the missile (change it using the .curve operator)
// readonly real veloc -> the missile speed (change it using the .speed or .duration operator)
// readonly real travel -> distance travelled
// readonly boolean launched -> true if the missile was already launched
// readonly boolean allocated -> true if the missile can still perform its movement operations
// //-------------------------------------------------------
// unit source -> the source unit (optional)
// unit target -> the target unit (optional and if set to a valid unit the missile will be homing)
// player owner -> the owner of the missile (optional)
// real collision -> the collision size of the missile (optional. The onHit and onDestructable events only works if this is greater than 0)
// real damage -> stores the damage you want the missile to deal (optional)
// real acceleration -> if different than 0 then the missile will change its speed with time (optional)
// integer data -> just in case you want to pass some information to the missile to retrieve it later (optional)
// (call)
// method deflect takes real x, real y returns nothing
// - Deflects the missile from the target point, changing
// - it's course to the new x and y.
// - If target is a valid unit, deflect will null the target
// - and then deflects the missile
// (call)
// method deflectZ takes real x, real y, real z returns nothing
// - Deflects the missile from the target point, changing
// - it's course to the new x, y and z.
// - If target is a valid unit, deflect will null the target
// - and then deflects the missile
// (call)
// method bounce takes nothing returns nothing
// - Bounces the missile from it's current Z position.
// - Useful when assigning targets to missiles that were
// - already active, it fixes the rough Z position change.
// (call)
// method flush takes widget w returns nothing
// - call this method to allow the missile to be able to hit
// - a unit or destructable again
// (call)
// method flushAll nothing returns nothing
// - flushes the hit table for the missile
// (call)
// method hitted takes widget w returns boolean
// - returns true if the missile has hitted the widget
// (optional)
// method onHit takes unit hit returns boolean
// - Runs every time the missile collides with a unit.
// - If returns true the missile is destroyed.
// (optional)
// method onDestructable takes destructable dest returns boolean
// - Runs every time the missile collides with a destructable.
// - If returns true the missile is destroyed.
// (optional)
// method onItem takes item i returns boolean
// - Runs every time the missile collides with an item.
// - If returns true the missile is destroyed.
// (optional)
// method onMissile takes Missiles missile returns boolean
// - Runs every time the missile collides with another missile.
// - By default, missiles collide only once
// - If returns true the missile is destroyed.
// - Please, be aware that this method can be very performance
// - intensive, so careful!
// (optional)
// method onPeriod takes nothing returns boolean
// - Runs every period.
// - If returns true the missile is destroyed.
// (optional)
// method onFinish takes nothing returns boolean
// - Runs whenever the missile finishes it's course.
// - If returns true the missile is destroyed.
// (optional)
// method onTerrain takes nothing returns boolean
// - Runs whenever the missile collides with terrain height
// - greater then the missile current z
// - If returns true the missile is destroyed.
// (optional)
// method onRemove takes Missile this returns nothing
