[JASS] Destroy Effects

[Waldbaer]

If I create special effects and don't manually destroy them, they will cause lag, even if they show only a short time like e.g. an explosion, am I right?

If this is the case, please help me with the following problem:
I have a spell and want to make it a little bloodier so I created a Blood effect on every of the target units. It's an AoE spell so there may be many units involved, but I don't know how many. I have a "Pick every unit in group and do..." loop and as actions I create the effects.
Is there any way to destroy them a second later without using global variables?

Thanks for help,

This Simply Destroys the effect as soon as its done.

call DestroyEffect(AddSpecialEffectTarget("SpecialEffectName.mdl", GetEnumUnit(), "Origin"))

This will destroy the effect as soon as it is created. It dosn't work well with all effects. It has something to do with the animations. I don't remember excactly. Otherwise if you want an effect to last some time, use Nantuko's Timed Effect script. I's really usefull.

Thanks for both tips!
In my case, the first possibility works fine, but I'll keep the second one in mind for future spells.
