[Trigger] quick question about location leaks

[pbnjamma]

i know you have to remove temporary locations when used in order to prevent leaks, but heres my question: if say a for loop assigns a temporary location each time around, do u have to remove the location in the loop, or can u do it after, and still have no leaks??

basically if a long trigger uses the same temporary location variable (but changes it) many times, can u just destroy it at the end? or after each use?

There are no for-loops in wc3
Anyway, every time you use a point variable you create a Location, which holds x,y coordinates.
The variable itself is just a pointer (which is why you DO NOT NULL GLOBALS OMFG (this is for all those that null globals)), therefor you will need to remove it every time you use it. Notice that you are removing the LOCATION, not the variable (yet again for those people...).

I think he means For each Integer x do y-loops.
If you want the variable to be differen every loop (like a random point), yes, you have to remove it at the end of the loop i'd say.. i'm not quite sure but works for me

It doesn't matter if it is random or anything else. Whenever you declare a point value (set VAR = some point, conditions containing points, reals containing points, anything that uses points) it creates a new object which holds inside it x, y and z values.
The variable (if you used one) is just "pointing" to that object.
If you didn't use a variable you do not have access to that object after it was used (which means the object just stays in the system without you being able to remove it).

What i wanted to say was that if one sets point x = random point in region x during a loop and does something else after, if the pointer is not deleted, the random point is the same as in the previous loop - at least for me..

thanks.

i have another question: do timers leak?

Integer, real, string, code and boolean does NOT leak.
Anything else does.
