How do you make special effects?

[Hohan]

I presume the circle spell animation for teleport is a special effect. If so, I would like to know how to use it.

Thanks.

Dawww Iono... What you can do is go to the ability and get the art model files, apply to a unit you arent using and put him on the map. See what the model looks like untill you find the right one, also check buff/effect models. When you find it copy the path and reset the unit. Tadaaaa

Add this to your map:

Special Effect Destruction
    Events
    Conditions
    Actions
        Custom script:   local effect tempEffect
        Custom script:   set tempEffect = udg_SpecialFX
        Wait 7.00 game-time seconds
        Custom script:   set udg_SpecialFX = tempEffect
        Special Effect - Destroy SpecialFX

Then you can just add this to your triggers:

Special Effect - Create a special effect at <point> using <SFX>
Trigger - Run Special Effect Destruction <gen> (ignoring conditions)

hmm....... like when you use a scroll of town portal or that tele to structure item. Thanks for the idea.

 

[Hohan]

wow you posted while i was typing kershbob. That would be my first specific custom trigger from another person . i'll try it.

 

[Kershbob]

That's the one blizzard uses for cleaning up SFX. Other people use other ones though but the idea is the same.

 

[AceHart]

You sure there's not something missing there,
like "Set SpecialFX = (Last created special effect)"?

 

[Kershbob]

Good point

 

[emjlr3]

what would it be corrected then, i would like to know....

 

[AceHart]

Special Effect - Create a special effect at <point> using <SFX>
Set SpecialFX = (Last created special effect)
Trigger - Run Special Effect Destruction <gen> (ignoring conditions)

or

Custom script: local effect tempEffect = (Last created special effect) (*)
Wait 7.00 game-time seconds
Custom script: set udg_SpecialFX = tempEffect
Special Effect - Destroy SpecialFX



(*) sorry, I never remember those GetLastSomething() in JASS

 

[emjlr3]

so your destrcution trigger would only need like

Wait 7.00 game-time seconds
Special Effect - Destroy SpecialFX
set SpecialFX = null

?

Special Effect - Destroy SpecialFX
set SpecialFX = null

Nop, you still need the entire code.
As SpecialFX is a global, its value may change during the 7.00 seconds of duration.
So storing it in a local variable and then removing is your best bet.

BTW, with GUI created Special Effects I suggest you to use AceHart's way.

[b]Special Effect Destruction[/b]
Actions
    Custom script: local effect tempEffect = [u]GetLastCreatedEffectBJ( )[/u]
    Wait 7.00 game-time seconds
    Custom script:   set udg_SpecialFX = tempEffect
    Custom script:   [i]set tempEffect = null[/i]
    Special Effect - Destroy SpecialFX

Underlined is what AceHart can't remember. You can also use bj_lastCreatedEffect
Also always remember to nullify your locals if they point to any handle (Added in italics)

BTW, a good improvement can be to be able to modify the time the special effect remains alive.

[b]Special Effect Destruction[/b]
Events
Conditions
Actions
    Custom script: local effect ef = bj_lastCreatedEffect
    Custom script: local real lifetime = udg_SFX_LifeTime
    Set SFX_LifeTime = SFX_LifeTime_Default
    Custom script: call TriggerSleepAction( lifetime )
    Custom script: call DestroyEffect( ef )
    Custom script: set ef = null

[b]Map Initialization[/b]
Events
    Map Initialization
Actions
    ...
    Set SFX_LifeTime_Default = 7.00
    Set SFX_LifeTime = SFX_LifeTime_Default

So in your code you can do something like

...
Create a special effect at (point) using (SFX)
Run Special Effect Destruction

Create a special effect at (point) using (SFX2)
Set SFX_LifeTime = 15.00
Run Special Effect Destruction

Create a special effect at (point) using (SFX3)
Run Special Effect Destruction

The first special effect remains alive 7 seconds (the default behaviour that can be changed at map initialization)
The second one remains in screen 15 seconds
Third also dies after 7 seconds because the trigger restores lifetime value to default.

I hope this clarifies (maybe not) and helps a bit.

Actually, this is the one of the few times i actually seen any custom scripts . Anyways I got this:

function Trig_Foot_Switch_to_Teleport_Actions takes nothing returns nothing
    call ForGroupBJ( GetUnitsInRectAll(gg_rct_Region_006), function Trig_Foot_Switch_to_Teleport_Func005002 )
    [B]local effect tempEffect = GetLastCreatedEffectBJ( )[/B]
    call PolledWait( 7.00 )
    [B]set udg_SpecialFX = tempEffect[/B]
    [B]set tempEffect = null[/B]
    [B]Destroy SpecialFX

[/B]

The lines that are in bold have some kind of error or something. Sorry about all this trouble I'm causing :banghead: .

 

[Hohan]

by the way, this is what i got so far....... im sooo lost im such a newbie.

Events:
Unit - A unit enters Region 010 <gen>
Unit - A unit enters Region 009 <gen>

Conditions:
((Owner of (Triggering unit)) controller) Equal to (Player 1 (Red) controller)
((Foot Switch 0068 <gen> is dead) Equal to True) and ((Foot Switch 0069 <gen> is dead) Equal to True)

Actions
Unit Group - Pick every unit in (Units in Region 006 <gen>) and do (Unit - Move (Picked unit) instantly to (Center of Region 008 <gen>))
Custom script:   local effect tempEffect = GetLastCreatedEffectBJ( )
Wait 7.00 game-time seconds
Custom script:   set udg_SpecialFX = tempEffect
Custom script:   set tempEffect = null
Custom script:   Destroy SpecialFX

Tell me if ive done anything wrong.

 

[AceHart]

> ((Owner of (Triggering unit)) controller) Equal to (Player 1 (Red) controller)

Replace this with a "player" comparison, not "player controller".

And, that trigger doesn't create any special effects.
Remove all that effect handling...

 

[Hohan]

i have no idea what you mean by removing special effects

 

[AceHart]

Your last trigger posted here has a couple "custom script" lines dealing with Special Effects.
Your trigger, however, doesn't create any.
So, why do you have those lines?

I hope this simple example map clarifies some things...
