Does Special Effects on Units leak?!

[NindoOne]

• Special Effect - Create a special effect attached to the origin of (Triggering unit) using Abilities\Spells\Items\TomeOfRetraining\TomeOfRetrainingCaster.mdl

Does this kind of special effects leak and if so, how do I remove them?

NOTE: I know how to remove special effects at a point but the sam thing dont work here

(How I remove SFX leaks at a point)

• NoLeak
  • Events
  • Conditions
  • Actions
    • Set point = (Center of (Playable map area))
    • Special Effect - Create a special effect at point using Abilities\Spells\Human\ThunderClap\ThunderClapCaster.mdl
    • Special Effect - Destroy (Last created special effect)
    • Custom script: call RemoveLocation(udg_point)

I will be happy for a quick answer!


EDIT: And also a quick question... Why the hell doesnt the effect work at all when its on a Unit?!

from what I understand..
Effects, objects, units all leak.

Integers and real don't.

You used:

• Set point = (Center of (Playable map area))

CENTER OF PLAYABLE MAP AREA

You didn't set it to a unit

You forgot GROUPS and POINTS.

an effect added on a unit works same like a effect added to a point

if it isn't removed, it leaks.

store the effect in a Special Effect variable and you can destroy it later

EDIT:

Effects, objects, units all leak.

how can a unit leak?

sure, a unit is a handle and takes part of the memory, but once the unit dies (decays, vanishes), he's automatically removed from the memory, unlike points and effects

Special Effect - Create a special effect attached to the orgin of (Triggering unit) using Abilities\Spells\Items\TomeOfRetraining\TomeOfRetrainingCaster.mdl

it should be "origin"

also, some units don't have certain attachment points

The 2:nd trigger is a correct SFX to a point... I'm just asking if the first exampel creates a leak and how to remove it I've been trying a bit more... Think i got it by my own, someone correct me if im wrong

Trigger:

• HPandMANAreg
  • Events
    • Unit - A unit enters InnerCity1 <gen>
  • Conditions
    • (Triggering unit) Equal to Hero[(Player number of (Owner of (Triggering unit)))]
  • Actions
    • Unit - Set life of (Triggering unit) to 100.00%
    • Unit - Set mana of (Triggering unit) to 100.00%
    • Special Effect - Create a special effect attached to the origin of (Triggering unit) using Abilities\Spells\Items\TomeOfRetraining\TomeOfRetrainingCaster.mdl
    • Special Effect - Destroy (Last created special effect)

 

[T.s.e]

sure, a unit is a handle and takes part of the memory, but once the unit dies (decays, vanishes), he's automatically removed from the memory, unlike points and effects

But the handle that points to the now-removed unit isn't automatically removed, so you need to null that handle, or it'll keep pointing to the removed unit and cause a leak.

By the way NindoOne, your trigger is leakless.

I thought only local variables should be nulled?
It applies to global variables, too?

Touché. It isn't necessary to null global variables, silly me has forgotten how GUI works.

You forgot GROUPS and POINTS.

He said objects, and those are objects. Anything that uses a handle Id is leakable.

Though nulling global variables isn't needed like locals, it's still nice in some cases. By nulling a global, you explicit that it's no longer in use.

if (udg_MyUnit == null) then
    call BJDebugMsg( "Variable is available" )
endif

You don't need Jass to null global variables in GUI though. I just used Jass out of not wanting to put it together in GUI. You can just make variables in the variable editor and never define them (i.e. create unit variable named nullUnit) then set variables to it (i.e. set SomeFootman = nullUnit ).
