Missiongroup and cleanup

Given this instance:

%obj = new Door() {

dataBlock = %block;

parentGroup = "MissionGroup";

};

Should I include this after creation ?

MissionGroup.add(%obj);

If I make the parentgroup equal to MissionGroup will it get automatically deleted on zone unload ?

I typically add the object after it's created (MissionGroup.add()) but parentGroup looks like a shortcut that does the same thing.

MissionGroup gets deleted when a mission ends and because it's a SimGroup, any objects contained within it will also be deleted.

As @Happenstance missionGroup gets deleted when the server ends. If you want a parentgroup which lasts through multiple missions you can test to see if it needs creating at either missionLoad/StartGame or mainMenu::onWake().

I tend to have a check in mainMenu::onWake() and create the group if it does not already exist or empty all the objects if the group is found (eg: you're back at the mainMenu because the whole game is over, so delete all the data that you've been saving in the group which will mostly be scriptObjects)

eg:

function MainMenuGui::onWake(%this)
{
   %group = masterCleanUp;
   if(!isObject(%group))
   {
      %strat = new SimGroup(masterCleanUp);
		echo("\c4New masterCleanUp");
	}
	else
	{
      %count = %group.getCount();
	   echo("\c4masterCleanUp already exists, empty it " @ %count);
	   if(%count > 0)
	   {
	      while(%count != 0)
	      {
	         %index = %group.getObject(0);
	         if(isObject(%index))
	         {
	            //echo("deleting " @ %index SPC %index.getName());
	            %index.delete();
	         }
 
	         //remember the escape
	         %count = %group.getCount();
	      }
	      echo("masterCleanUp emptied");
	   }
	}
}

Using that while() loop is actually a terrible way of doing this but hey :lol:

edit: should just use %group.deleteAllObjects();

function MainMenuGui::onWake(%this)
{
   %group = masterCleanUp;
   if(!isObject(%group))
   {
      %strat = new SimGroup(masterCleanUp);
		echo("\c4New masterCleanUp");
	}
	else
	{
      %count = %group.getCount();
	   echo("\c4masterCleanUp already exists, empty it " @ %count);
	   if(%count > 0)
	   {
	      %group.deleteAllObjects();
	      echo("masterCleanUp emptied");
	   }
	}
}

I'm gonna go change my code now ... :oops:

What will happen in the case where you group together items in a sim set , that sets the parentGroup of the item to the name of the sim set .

btw my version is 3.9

simSets are lists of refs. simGroups are lists of actual objects. Kill a set, all you're doing is killing of a bunch of pointers. kill a group, everything's gone. (it's why stuff can be in multiple sets, but only one group)

Thanks for all the answers.

@Steve I didn't realize you could get a count, now I can verify a clean delete, great idea...
