[Trigger] Nullify Vars in GUI

[xD.Schurke]

Because i have to do something in gui again... i wondered if i can nullify vars in gui like

• Custom script: set udg_var = null

thank you for help

okay, if he says so^^, thank you , can't u rep , because i already gave rep to you some time ago, you get it later

Not strictly speaking true, actually. Globals do still stop the index from recycling. Normally this isn't an issue, as the variable gets set to something (and thus the reference counter decrements), but if you leave it pointing at the handle... Mainly significant with arrays.

And you can just set it to no unit/whatever, no need for custom scripts.

What's the chance you will ever get to the maximum with globals (the only big loops I ever saw were in physics and stuff made with Jass)?
Still good to know that for general knowledge (not that I care for a shnitzel about warcraft anymore, but whatever).

Also don't forget to destroy pointing leaks (most common are locations, unit groups, and special effects, of course).

Not nullifying globals pretty much means that the index won't be recycled, so if you're using something like DataSystem that relies on free indexes in a handle array (based on the amount of active handles), well you're pretty much fucked. So nullify globals that could take up alot of handle indexes.

y i know good about leaks... i only wanted to know if it is nessesary to nullify globals^^

If it would be, then you'd either be

• Using an array
• Using a global where you should have a local

usualy i would use a local, but in this case i can't use jass... i promised, and so i wondered XD
