[Trigger] How many times can a handle leak?

[Hugget Sukker]

If I want to use a function like Center of PlayableMapArea, which I understand leaks. If I want to use it several times, I don't have to destroy it, right? Or is Center of PlayableMapArea actually a new handle each time I refer to it?

Then what if I Pick all units in EmoRegion and do actions. When I refer to that handle later, some of the units might be dead or gone, and new units might be in the region now. So all units in EmoRegion is a different group now only if the contents have changed, or simply everytime referred to?

If you're gonna use a location many times, you'll only need to set it once.
But if you're going to re-set it, you have to destroy it first

• -------- every time it is called, it create a new location. so do this --------
• set temploc = Center of (Playable map area)
• -------- add your own stuff here, using the variable temploc --------
• Custom script - call RemoveLocation(udg_temploc)

Okay, so dansaDisco is talking about setting a variable to the location, not calling the location many times and then cleaning the trash, but cleaning up everytime you mess a bit. Or at least, making sure you have a variable set to it until it is destroyed. Think I get it now. Thanks. And thanks for a really speedy response!

the advantage with creating/destroying is that you can use the same variable in every triggers, so you won't have a hudge list if you need many different locations. But if you need only this one, you should pre-allocate once.

I have another question, but don't want to make a new thread.
Do regions leak? And how do I destroy them?

• Custom script - call RemoveRegion(udg_tempreg)

Like this?

 

[IaMfReNcH]

• Custom script - call RemoveRect(udg_temprect)

if I remember, It's that. It leaks when you create a new one with triggers. But if you placed a region graphically with world edit, it's created once for all.

You can destroy regions created with world editor. The variable for a region called My Region would be gg_rct_My_Region.
