Black Hole

Requested by darkwulfv and spawned from the Spell Request thread. Requires cohadar's ABC System to be used.	Thread Spell Request Thread
The hero tears a hole in the fabric of space, creating a black hole that sucks enemy units within a X AOE radius. Enemy units who stray too near and get within Y units near the black hole will get sucked in. After Z seconds, the black hole collapses and explodes, dealing XX damage in a YY AOE radius and knocking them backwards. Units sucked in the hole will also get damaged and be thrown out of the void it was sucked into.	Written by Malf

waaaks	ive seen 2 black hole spells already, and tried to import in my map, but they affect structures which i dont want to affect, i tried configuring them but still affect the structures i hope this doesnt affect structures is this a system?

Malf	If you've configured them then it might be a problem with those spells. This is a normal spell, doesn't follow the JESP standard since I was too lazy to add the JESP manifest. The spell itself is 100% configurable though. Btw, I'm noypi as well =þ

cohadar	Always post the spell code.

I've done a quick review, and this is what I've found:

You are not indicating that your system uses ABC from cohadar (yes cohadar, kill him :P) Please add this to the first post.
If I cast the spell very near to the caster, the caster is knockbacked with the enemies, weird!!
You use this formula to calculate the movement:
JASS:
```
set x = x + d.expiration * Cos(a*0.01745)
set y = y + d.expiration * Sin(a*0.01745)
```
You are summing distance with velocity. If you want to be more accurate, you should use d.expiration * SUCK_INTERVAL and it's more unit homogeneous (sum distance with distance).
You must set the dust effect as a constant global.
Just a suggestion, your indent makes look your code messy, try to add more spaces, it helps a lot to read the code.
There's already a BlackHole spell (a JESP one) done by Blade.dk. You can see it here

Because this spell has been done, in theory I should graveyard this, so I need a good justification why it should be approved.

Because the spells are different.

Blade's removes the units entirely and damages nearby ones.

This one sucks enemies in and holds them there, then the black hole implodes, sending the ones sucked in flying and damaging other units.

I think this was intended. If you made a black hole in your face, I think you'd be eaten by it as well.

I will let him live for now.

Mainly because he knows how to import ABC.
(You would be surprised at the amount of people who copy whole ABC text on top of their trigger text, they think it is a macro or something!? )

He also used private actions and conditions, that is a big plus.

He did not use local trigger:

JASS:

function InitTrig_Black_Hole takes nothing returns nothing
 set gg_trg_Black_Hole = CreateTrigger(  )
 call Preload(BlackHole_FX)
 call Preload(Explode_FX)
 call Preload("Objects\\Spawnmodels\\Undead\\ImpaleTargetDust\\ImpaleTargetDust.mdl")
 call TriggerRegisterAnyUnitEventBJ( gg_trg_Black_Hole, EVENT_PLAYER_UNIT_SPELL_EFFECT )
 call TriggerAddCondition( gg_trg_Black_Hole, Condition( function Conditions ) )
 call TriggerAddAction( gg_trg_Black_Hole, function Actions )
endfunction

JASS:

public function InitTrig takes nothing returns nothing
    local trigger trig = CreateTrigger()
    call Preload(BlackHole_FX)
    call Preload(Explode_FX)
    call Preload("Objects\\Spawnmodels\\Undead\\ImpaleTargetDust\\ImpaleTargetDust.mdl")
    call TriggerRegisterAnyUnitEventBJ( trig, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( trig, Condition( function Conditions ) )
    call TriggerAddAction( trig, function Actions )
endfunction

// InitTrig is public, remember that.

The greatest remark is terrible indentation of the code.
Learn to use tabs instead of spaces.
(or use 4 spaces if your editor does not support tabs)

------
This is close to being JESP, he just needs some more work.

EDIT:
You should use this for a spell icon:
ReplaceableTextures\CommandButtons\BTNGenericSpellImmunity.blp
It is an active spell after all.

The caster is not eaten, only knockbacked. I think this should be configurable in the spell too.

It's not necessary to make it public.

Yes it is.
(when you are naming it only InitTrig to avoid WE dependence.)

I didn't use a local trigger because:

a. The global is created anyways
b. Some people may want to disable triggers dynamically

Oh and I know about Blade.dk's blackhole, I ripped off the model from his demo map =þ
_________________________

You can determine which units are sucked in, it's just below some constant functions and is explicitly named Filter

The InitTrig is called 'InitTrig_Blackhole' so I do not need to add a public/private prefix.

My calculations are fine, d.expiration*SUCK_INTERVAL just determines the speed travelled per second in wc3 units(for example, 800 units per second)
Which means I'd have to do something like this

JASS:

    if d.expiration < d.distance then //d.distance == d.expiration*SUCK_INTERVAL
        set x = d.x + d.expiration * Cos(a*0.01745) //Uses a local var 'x'
        set y = d.y + d.expiration * Sin(a*0.01745) //and local var 'y' instead of d.x and d.y
        set d.expiration = d.expiration + SUCK_INTERVAL
    endif

Oh and sorry cohadar, I forgot to say in the first post that I use ABC.

Check first post for the new link for the newer version of the demo map. I've included some minor changes and added a filter for units who should be knocked back.

waaaks	ok i tested the spell...it was cool but its lag

11-13-2007, 07:08 AM	#12
Malf	It's not laggy, even on my computer. It just so happens that I've amassed trolls in the map so the units are the ones who are affecting your computer's lag issues.

11-13-2007, 09:04 AM	#13
waaaks	ah ok maybe ill use that in my map :D lol - moyack removed it :P

11-21-2007, 05:42 PM	#14
Pyritie	This would be sweeter if it had some levels.

11-23-2007, 11:07 AM	#15
Malf	That's why I split some constant globals into constant functions. There you can just set a formula like 50+10*level It supports levels.
