Memory leaks

[manstie]

Basic question here...

Does Starcraft 2 have memory leaks?

No, starcraft has garbage collector, you can create whatever you need and leave it, it will be dealt with.

With in reason, SC2 will not leak.

Obviously you can have leaks in the case of not nulling un-needed globals but this will only ever be very small. Also not everything is recycled so it is possible to leak units if you do something stupid (make sure you remove them or allow them to be killed).

Locals will not leak in SC2. Unit groups, player forces and locations (well their SC2 equivilent) all do not leak (they get removed if no variable points at them).

yes it has look into the galaxy script file (where all natives are listed) there is a list of var-types which have to be cleared manually

Does not setting up any local variables and doing an action "directly" (without a local variable) such as "create unit at (center of region 1)" or so leak for example?

No... Why should it leak?

The reference count of the made location is 0.
The garbage collector handles that object type.
Thus the location gets removed automatically.

Setting it to a local will also mean it does not leak cause I am sure blizzard removes reference counts of all variables on the stack.
