Ryoko - tutorial site clarification

[kingofdeth]

Ryoko

I was looking at your tutorials and i noticed a custom text that you never explain. What does bj_wantDestroyGroup=true do?

ps sorry for putting your name in the subject but this is a question specifically for you.

I will let the mod name in the subject rule slide this time but in the future try to post more descriptive in the subject if you are looking for an exception. The mods most likely are going to read all posts anyway.

Sorry to be so strict but the rules are in place for a reason. Thanks for the heads up on the tutorial issue though. Feedback on that is most welcome.

A better title for this thread, imo, would be Tutorials Site Questions and/or Clarifications. That way it could be reused.

I guess this is about clarification on something Ryoko wrote, so in that sense its okay, but I will add a bit extra to it just to stop it being so vague.

If you create a "pick every unit..." unit group trigger action and don't assign the unit group into a variable, you will instantly create a memory leak in the game. If that line of JASS code is put before the unit group is declared, then the unit group will get automatically removed from memory after use, thus avoiding the leak.

Example:

Pick every unit in (units owned by player 1) and do....

on its own will cause a leak.

bj_wantDestroyGroup=true
Pick every unit in (units owned by player 1) and do....

stops the leak.

set unitGroupVariable = (all units owned by player 1)
Pick every unit in (unitGroupVariable) and do....

also stops leaks.


This unit group thing is one of the major causes of game slowdowns, which is why we have to take actions like this.

More information on memory leaks is available here:

Also you should open the Blizzard Tower Defense map to see examples of where Blizzard have used this piece of JASS code.

Thanks Darg

No good place to explain that one yet.
