[JASS] fixing memory leaks

[Draqz]

ok, so my map is leaking and im not sure why, i was very careful about destroying and nulling my locals. I do have one quick question that one of you might be able to answer.

If I have a local location, can I use that same location and keep reassigning new locations to it until the very end where i destroy and nullify it? or does it get lost in memory if I don't null the previous value before i reassign a new one?

Well, i'm not 100% sure, so anyone might correct me if i'm wrong.
If you use any native/function returning a location it'll leak, because you overwrite the old handle with a new one, but if you MOVE the location it won't leak, due you still use the old handle.
So don't create a new location just move the old one or destroy it before assigning a new position of the location.

You don't have to null it every time, but you have to destroy it every time..

Eg.

local location x = Location(0,0)
set x = Location(0,0)
call RemoveLocation(x)
set x = null

leaks

local location x = Location(0,0)
call RemoveLocation(x)
set x = Location(0,0)
call RemoveLocation(x)
set x = null

doesn't leak

hi

if u dont nullify values they get lost in memory and cause lagg.

 

[frenksel]

what he said!

Wrong.

If you don't destroy objects, they take up memory.

If you do not null non-permament handles, then their handle slot will eventually leak, taking up memory unnecessarily.

I already answered it, Griffen ><

frenksel gave a wrong answer though. You also didn't explain why, and I'm sick and tired of being one of the few people who actually seems to understand pointer leaks.

hmm... just looked at this thread here..

i have a problem with my map too. its the same bug as in Tides of Blood.
whenever i want to play any other map than mine (after i played mine) i get a server split and leave the game.

is there a simple command to unload every variable or whatever.. to clear the memory or so?

some kinda "if i leave the game, clear everything".

That's the Widgetizer, if you use it.
