2 Memory Leak Questions

[LucidWay]

*I can't count: 3 ?'s*
Ok, so in the tutorial, it said these values cause memory leaks:
Points
Unit Groups
Player Groups
Special Effects
Strings
Regions

Question #1:
No other data types cause leaks? Local integers from functions etc....?

Question #2:
If I have a loop where i redefine a leaking data type, do I only have to remvoe that variable once?
Ex:

local group TempGroup
loop
      exitwhen (XXX)
      set TempGroup = YYY
endloop
call DestroyGroup(TempGroup)

Question #3
If I have a global group arrary (Groups leak), and want to use that global group in a trigger. Do I need to make a local group with the specific array group then delete that?
Ex:

    set TempGroup = udg_GlobalGroup[X]
    set TempUnit = GroupPickRandomUnit(TempGroup)
    call DestroyGroup(TempGroup)

Thanks a bundle.

Numbers don't leak.
Which includes integer, real and boolean.
Strings are handled slightly differently, but there's nothing you can do there anyway.


Every time you create a group, you also need to destroy it.
Especially if it is local.
You also need to "set variable = null" once done with the group.


Q3 is a bit unclear...

> set TempGroup = udg_GlobalGroup[X]

This will not make a copy of that group.
You might just as well use the array one.

thanks

You also need to "set variable = null" once done with the group.

You mean i need to do this in the loop? Do I also need to do this with other variables in a loop or just leaking ones?

Thanks

local group g = CreateGroup()

...do somthing with it...

call DestroyGroup(g)
set g = null

You only need this once, after being completely done with the variable.
And, yes, using "set myInteger = 0" is just a waste of time...

unless ofcourse u create a new group each time, in which case u need to destroy the last, but it only needs to be nulled once
