Yet another leak question

[Lahey]

Does this leak?

Set Point1 = (Center of region1 <gen>)
*goes in loop*
Item - Move (Picked item) to Point1 *an then like 20 times this move action*
Custom script: call RemoveLocation (udg_Point1)

If this doesn't leak then I don't really see the point in removing the location. Because the variable is already there from the beginning of the game and it's value will only be replaced by another value when it's set.

Well, as long as you donät set it to another value before destroying it, or use any waits it won't leak

Ok.

Now what does the script remove? The value of the variable? That would be silly. Or does it delete some garbage code? If so, when is this garbage code created? When the variable is set or when it is used?

It removes the allocation of the memory

"Typically, a memory leak occurs because dynamically allocated memory has become unreachable." - Memory leaks - en.wikipedia

I'm not sure when the leak occurs, as I don't know how Jass allocates variables. My guess would be that a point variable is a pointer to a loc object (struct) which is not freed when assigning the pointer to a new value, thus creating a memory leak. It may seem stupid but probably Jass wasen't invented to create a base for GUI.. as memory allocation and freeing (destorying) was intended to be done by user (in jass).. which is why you should use Custom script: call RemoveLocation (udg_Point1).. :thup:
