[JASS] How to set unit = null in this situation?

[lang_dye]

function XXXX takes group u returns unit
.........
return unit
endfunction
so this function is end in return unit,and can I set unit = null behind it?

 

[DracoL1ch]

use a temp unit global variable

set tt_unit1=u
set u=null
return tt_unit1

Are we sure that leaks though?

If so maybe usebj_lastCreatedUnit

 

[DracoL1ch]

any global will work

I suggestedbj_lastCreatedUnitbecause it's because it's better than creating a global just for this.

Yes any global will work.

Have there been any tests to prove this actually leaks, though? It's likely that it does, but who knows.

 

[DracoL1ch]

you can create a single global var as well, or use any of 100s pre-generated by blizzard. w/e

Using bj_ globals might be good, because one does not have exclusivly to create global variables for returning.
How ever, I don't say it would be good practice, but it's still possible that the user doesn't want to get this variable overriden by random systems where he would not expect it.
It has some tiny potential to break some code, if the user does bad practice.

maybe.

use a temp unit global variable

set tt_unit1=u
set u=null
return tt_unit1

get it.
