[Trigger] Question about leaks

[HamzahA]

i use some possible leaking variables like Temp_Point , Temp_Group and so on, i use them on more than a trigger, and never remove them, does each 1 leaks only 1 time or it leaks on number of uses?

Every time you use the trigger it leaks again.
Triggers that run multiple time should ALWAYS be leakless !

If you don't know the custom script to remove leaks here it (they) is:

Point remove

• Custom script: call RemoveLocation(udg_YourPoint'sName)

If its an array just put "(udg_YourPoint'sName[array])".


Unit Groups

• Custom script: set bj_wantDestroyGroup = true

Put this BEFORE you pick the units and it will remove the unit group after it finished using it (don't use this if you have more uses for the group).

• Set Unit_Group = bla bla bla
• Unit - Order Unit_Group to bla bla bla
• Custom script: call DestroyGroup(udg_Unit_Group)

Use this if the group has actions after the unit group did its unit group actions.

but its the same variable!

When you use a Point variable or a Unit Group variable it makes a new one and does nothing to the old one.

I never understood why globals leak... If they're global, why are different instances of them made everytime you run a trigger?

 

[GhostWolf]

Dunno, I don't know much about programming, try to ask in the JASS forum if you want to know.

 

[HamzahA]

hmm are you sure 100% about this? or there is a chance of ur mistaken?

I've made a map that were setting around 1000 point variables/second... it didn't lag at all. Even if I played it for 4 hours.

[EDIT]: And that's 1,440,000,0 (fourteen millions and fourhundred thousand) variables...

Well, if you want, you can check it on your own - just make a periodic trigger

• Events:
  • Time - Every 0.5 second of game time
• Conditions:
• Actions:
  • Set TempPoint = (Random point in(Playable map area))
  • Unit - Create 1 Footman for (Player 1(Red)) at TempPoint facing (Default building facing degrees)

Every 0.5 second new unit and point are created, but are not removed - run map and wait few seconds, game will start to lagg like hell, even if its not online.
After your w3 (probably) crashed, just add the remove TempPoint custom script line at the end of the trigger, run map and wait. The game should start lagging a lot later.

Arh... faster.
Well, you know, just setting variables and leaving them unused doesn`t leak. But when you create a unit/special effect/anything, then it leaks.
