// Forest Soul v1.06 by Meatmuffin
// Conjures the very essence of the forest and sends it
// to the target enemy. Once it reaches the target, it will
// circle around it, taking its life force and sending it
// to the caster. After that, returns to the caster and
// repeats the same action. Meanwhile the forest spirits
// guard the caster, pushing away enemies based on the time
// the soul was circling.
//
// The functions below are meant for configuration only.
// Anything below the configuration can be changed,
// although it does take some programming knowledge to do so.
//
////////////// HOW TO IMPORT ////////////////
// 1. Go to File -> Preferences and tick the box that says:
// "Automatically create unknown variables when pasting trigger
// data"
//
// 2. Copy the dummy unit (if you don't have one) and the
// ability and match their ID's with the configuration.
//
// 3. Copy the "Forest Soul" category into your map along with
// the variable creator. Variable creator creates variables for
// you so you don't have to manually create them yourself.
//
// 4. Configure the spell as it fits best for your map.
//
// 5. Enjoy!
//

// The looping speed, this indicates the time between

/////////////////////// END OF THE SPELL //////////////////////
In the phase 1 of the spell, the caster is sending out a spirit in a
parabola graph. I set the default speed to quite low for phase recognition. This phase doesn't do
that much, it's only a followup to the damaging/healing phase (2).
In the phase 2 of the spell, the spirit is leeching life from the target
and sending it instantly to the caster while rotating around the target for aesthetic reasons.
The caster will still get healed if the target takes low, or no damage at all.
In the phase 3 of the spell, the spirit returns to the caster
(I set the default speed to high, since it's basically a transition to phase 1 again) and increases
the AoE of the pushback radius.
Throughout all of the phases, there is a spirit hovering the caster at a set radius.
The spirit indicates the pushback AoE. Any enemy that comes close to the target will get slightly
pushed away. I implemented this because the caster is a little fragile while casting this. If anyone
requests, I will add an option whether it should be enabled or not.

Changelog


v1.00 - Initial release
v1.01 - Optimized the code based on BPower and KILLCIDE reviews.
v1.02 - Removed a leftover, parabola is a little smoother now (?)
v1.03 - Added an option to break the spell using max distance.
v1.04 - Implemented a seperate parabola distance calculation to make it look completely smooth now;
Added functions: 1. Target filter for easier filtering, 2. A check whether the caster is already channeling or not.
v1.05 - Updated the parabola to be proper with different starting/end heights. Gonna update to 1.05b later today if the circumstances are in my favor.
v1.05b - Improved compatability when the caster's height is heigher than the target's.
v1.05c - Fixed some visual/testing issues and fixed the bug after the discussion in chat with T-C.
v1.06 - Radically optimised the code, cutting down the distance calculations, locals count and resource code lines in general. Credits to T-C again.
v1.06 again - GIF preview.

Note:
I will probably have to use world bounds and not move the indicator if it is out of map bounds.

Feedback is very welcome.

First impression:

Pretty cool idea.

For me FPS drop rapidly if many units are affected. ( Casted in the north-east bear group )
Could be the fx model or something within the code.
I would guess it's this aura a-like fx for close affected units.

From set z = 4.00 * FS_ParabolaHeight() * partialD * (totalD - partialD) / (totalD * totalD)
(totalD * totalD)--> Make sure this can't be 0, otherwise the thread will crash due to (x / 0) division.

set udg_FS_AbilityLevel[Node] = GetUnitAbilityLevel(udg_FS_Caster[Node], 'A000')
^'A000' should be replaced.

GetUnitCurrentOrder(udg_FS_Caster[Node]) == 852600
^I would appreciate if you place the order id into a constant function.

if not (IsUnitType(udg_FS_Caster[Node], UNIT_TYPE_DEAD) == true) then
--> if not IsUnitType(udg_FS_Caster[Node], UNIT_TYPE_DEAD) then
^The == true comparison is redundant.
It's a classic issue of improving close to zero performance, but it looks cleaner.

A proper IsUnitDead comparison includes a GetUnitTypeId(unit) != 0 check,
because UNIT_TYPE_DEAD doesn't work properly for removed units.
It looks like if not IsUnitType(u, UNIT_TYPE_DEAD) and GetUnitTypeId(unit) != 0 then

Deg2Rad(angle) is slower than angle*bj_DEGTORAD

call SetUnitState(udg_FS_Caster[Node], UNIT_STATE_LIFE, GetUnitState(udg_FS_Caster[Node], UNIT_STATE_LIFE) + udg_FS_Damage[Node])
--> Better go with native GetWidgetLife and SetWidgetLife.

JASS:
        if (udg_FS_CastedCount == 1) then
            call TimerStart(udg_FS_Timer, FS_TimerSpeed(), true, function FS_Loop)
        endif
^Just for the record: This comparison could replaced by udg_FS_PrevNode[Node] == 0.
But using a counter is also totally fine.
 
Only skimmed the code. I will take a more in depth look later!

  • Needs more white space :p
  • FS_CastedCount currently only acts as some type of indicator to start and pause the timer. You can get rid of it and do it like this:
    JASS:
    //on cast
    if udg_FS_PrevNode[Node] == 0 then
        call TimerStart()
    endif
    
    //on deindex
    if udg__NextNode[0] == 0 then
        call PauseTimer()
    endif
  • Deg2Rad(GetRandomReal(1, 360)) Angles start at 0, not 1 :p
  • Use a variable like DistanceTraveled = DistanceTraveled + Speed to see if the soul has reached the caster. It's less taxing than having to constantly keep calculating distance
  • Some things that I think shouldn't be hardcoded: attachment point of SpecialEf / channel order id / Flyheight when transititioning to phase 2 / integer id in UnitApplyTimedLife

EDIT: Wow.... darn you BPower. I was editing mine and making it look nice :(

Thanks KILLCIDE and BPower, will get straight to it :p

~Updated. The only thing I didn't do was implement a DistanceTravelled variable. It does make lots of additions each loop, also if I would keep one then there would be some sense to use it on the first phase as well, but I can't use it that way, since the target is moving -- anyway, thanks!

Also added a counter effect duration just as I did with the life draining effect, to the pushback effect, to make it less spammy. Thanks BPower.

Oh my apologies. I didn't realize the target can move. If that's the case, add another configurable of what value should a missle be considered "within range" of a target. A couple of other things:
  • Get rid of set udg_FS_CastedCount = udg_FS_CastedCount + 1 & set udg_FS_CastedCount = udg_FS_CastedCount - 1
  • JASS:
    if udg_FS_EffectDuration[Node] < 0.00 then
        call DestroyEffect(AddSpecialEffectTarget(FS_DrainingEffect(), udg_FS_Target[Node], FS_DrainingEffectLoc()))
        call DestroyEffect(AddSpecialEffectTarget(FS_DrainingEffect(), udg_FS_Caster[Node], FS_DrainingEffectLoc()))
        set udg_FS_EffectDuration[Node] = FS_EffectInterval()
    endif
    ^I'm assuming you did this to add amplification to the SFX? I recommend using a loop and adding a configurable to how many of the same effects will happen at this part.

I like the special effects. My only gripe is how awkward it looks when the missle reaches its target in the middle of the parabola.

There is a configurable for target range, not for the caster range, that's hardcoded, will implement this.

Oh yeah, that casted count, forgot to remove it.

In that loop, I decrease a duration and when it ends, I create a special effect at the caster's origin and at the target's origin because if I don't, it looks ridiculous and I guess it's laggy when you spam it. I'm .. not entirely sure what you meant by that.

I guess instead of using a GetUnitX(FS_Target[Node]) I can get the radius offset from the target to make the parabola look smooth. Thanks for the input :>

Now that I look at the parameters, I didn't realize they were casted on different targets xD my bad.

I thought about adding a max distance, but then it would be too underpowered. And think about it, it's not really beneficial for the caster if the target runs away far enough -- the spell becomes less efficient, since it requires time to transition between phases (that being the speed of the soul in p1/p3)
 
Quite a nice idea
Just some quick things I noticed:

Major:
- You don't need to set x3/y3 to any value unless it's in phase 1 or 3 (you have an if condition which already checks this, and it's otherwise not used)
- you can reuse x/y values that aren't used again (for instance you don't need x2/y2 in the onCast function
- You can channel on multiple units at once while moving cancels; this could be optional since normally you wouldn't be able to do it
- The ability works on enemies and allies (you can also target yourself)

Minor:
- Target filters could be in their own function (so it can be altered more easily by users)
- No proper manacost or cooldown
- you should add/remove stormcrow form to any dummy that has fly height controls (allows things like ground & floating dummies to have flyheight changed which has slightly different implications and sometimes different visual effects)
- levelup trigger can cause your unit losing the ability (a bit irritating when testing but nothing to do with the ability)

I'd appreciate if you'd tell me how to do that :p.

As for the other major things, I did them except for the re-using x/y values. In the onCast tried to reuse the same, it bugged out. As for the loop, I know some of them are a bit redundant, though I did it for easier editing and readability.
 
I don't follow why it would bug unless you did something odd with it given you don't refer to x again after you assign x2, perhaps you didn't change a variable reference?

eitherway when preventing multiple channelling the easiest way to do that is to run a check if the unit already has an instance tied to it when it attempts to cast the spell again - normally a O(n) search through the linked list for instances where the Caster[Node] == unit
you can then instantly terminate that instance (setting the duration to 0) or overwrite the instance with all-new data - the former is easier to do but both are valid methods
 
While testing I encountered this major bug (appears to be related to multiple instances either recycling or channel cancelling - I've included both a still image of the frame the bug occurred and the GIF of my complete actions starting from the first cast
(Specifically I start 3 casts then restart the 2nd one - the return projectile from the restarted 2nd one appears to be the specifically bugging component)

As a side note it looks pretty odd when the the energy is going through the ground like in the other attached image, is that intentional?

Ah. When I was playing around with air units, i didnt add the soul height to the formula. Will fix.

Oh I see, that explains things. Will fix.

Will check out the bugging in a bit.

~Edit: Updated after the discussion in chat.
~Edit2: Radical code efficiency update.
