[JASS] Simple Question

[Dreadnought[dA]]

If you set a location = null does that clean it up?
I heard somewhere that unit locals leak as well, is this true?

Do strings, groups, units, players, and other things leak?
Can they be fixed by nulling them?

Thanks for your time...

Every handle (being any variable beside integer and real (strings leak because of wc3's engine but there is no way to remove it so just ignore it)) need to be nulled when it's use is finished.

Obviously a local's use is finished after the function it is in is finished so it must be nulled within it.

Anyway, locations, groups, special effects and such things are POINTERS. They point to objects that hold the real values (location points to a object that holds x,y coordinates, for example) and thus those objects need to be destroyed BEFORE the variable is nulled.

Location - RemoveLocation(var)
Unit Group - DestroyGroup(var)
SFX - DestroyEffect(var)

etc.

When you destroy a group do you have to null it as well before the end of the function?
