Memory Leak Issues?

[futeki]

Are there any memory leak issues with resetting variables over and over again?

I'm constantly changing variables, or zeroing them out. I've been searching the forum and can't seem to find anywhere anyone has addressed this...

Well, depends on the variable. If the variables don't leak (real, integer, etc), then there isn't a problem. However, for variables like point, unit group, etc. there is a problem if you don't remove the leak before resetting the value. For example.

Leaks:

• Actions
  • Set TempPoint = (Position of MyUnit)
  • Custom script: call RemoveLocation(udg_TempPoint)
  • Set TempPoint = (Position of MyOtherUnit) <-- Leaks here

Does not leak:

• Actions
  • Set TempPoint = (Position of MyUnit)
  • Custom script: call RemoveLocation(udg_TempPoint)
  • Set TempPoint = (Position of MyOtherUnit)
  • Custom script: call RemoveLocation(udg_TempPoint)

Glenphir...your first trigger doesn't leak either :S.

You have to set the point again after the second time, thus nudging the old data into backlog. If you don't ever use that point again, it doesn't leak :S.

depends on what you define as a memory leak, any usage of memory or just the unrecoverable loss of memory. as it seems glenphir uses the first definition given.

What about strings? I'm constantly changing strings for use later on...

there are only some variable types which leak memory, these are "locations", "unit groups", "forces", "rects", "special effects", "floating text", etc etc.

basic classes like integers, reals, strings, booleans and such do not leak. neither do units, players, items, and such.

I don't think strings leak.

Edit: Late .

So, does that include integer and string arrays?

integer or integer arrays do not make any difference for leaks.
