Custom text: Destroy unit variable?

[SlasherXpert]

Whats the script for destroying a unit variable?

For unitgroups it's:

Custom script: call DestroyGroup(udg_UnitGroup9)

the UnitGroup9 being your variable name but how do you change it to affect "unit" variables instead of "unitgroup" variables?

 

[AceHart]

Nothing to destroy there.

With locals you simply "set variable = null", with globals it's done already.

 

[SlasherXpert]

so how exactly do you do it?
Do you use the set variable function?
Or is it some other custom JASS-y function?

*Edit*: I can't find the "null" function in the set variable thing
does it work if I do:

Set UnitGroup1 = (Units in No region)

Would it work or would it leak and cause lagg or crashes?

*Edit*: I found a alternative way so i'm ok.

The way to destroy a unit is RemoveUnit(unit), but that will remove the unit from the game, so you just need to assign null to the variable by:

set unitvar = null

in JASS.

in GUI it is : set unitvar = No unit

I think global variables in GUI already null themselves so it is useless to set a global to null.

That's what I read somewhere though. Maybe wrong.

well they don't exactly destroy their value, but when you reassign them the old value is gone.
however locals create themselves again every time you run the function they are in...and when the function is done executing the local is lost, but its value still stays in the memory.
of course this leak is minor...about 10 bytes i believe. if your trigger only runs once then you don't have to worry about nulling them.

It takes 4 bytes.
