Deleting all objects of a specific class?

#1 I'm not sure if there's an easy way to do that. I guess what I'd do would be to put them all in a SimGroup and then just delete the SimGroup when you don't need them. SimGroups are like SimSets except any object can only be in one SimGroup and if the SimGroup is deleted, all the objects inside are too.

Hope that helps :)

#2 Using a SimSet would be the less error prone way to do it but if you simply want to list all objects of a certain type then you could use something like this (this is for datablocks):

%dbSet = getT2DDatablockSet();
    %cnt      = %dbSet.getCount();
      
    for( %i = 0; %i < %cnt; %i++ )
    {
         %db = %dbSet.getObject( %i );
      
         if( %db.getClassName() $= "t2dImageMapDatablock" )
         {
               ... // Do something with the datablock
         }
    }

edit:

I obviously just jumped in without checking what you required specifically so here is how you would do it with sprite objects in the scene graph.

%cnt = YourSceneGraph.getSceneObjectCount();

    for( %i = 0; %i < %cnt; %i++ )
    {
         %obj = YourSceneGraph.getSceneObject( %i );

         if( %obj.getClassName() $= "t2dStaticSprite" ) // change to classes you want
         {
                ... // do something with the object
         }
    }

#3 Sweet, Neo. I always assumed that there would be a way to do that, but never bothered to see how ;)

I love these forums :)

#4 @Neo: That's a great solution, either for this or many other uses. I've been using a SimSet and that's been working well for just pure deleting but this solution will come in handy when I need to make global changes to a class.

@Tom: I thought about using a SimGroup but I'm always iffy about them for some reason. A SimSet "feels" safer. I don't know why. ;)

Thanks for the feedback, guys!

#5 @Neo, I'll make sure your examples wind up in the class docs for t2dBaseDataBlock and t2dSceneGraph, along with attribution.

#6 @Arthur:
Glad to help your project too, it really is commendable. Feel free to pick my brain for anything else you might need.

#7 Thanks! Sure thing. (See you over in GoogleGroups.)
