SimGroup and safeDelete

by Bryan Edds · in Torque Game Builder · 04/05/2005 (4:05 pm) · 3 replies

Hi, I'm adding some fx2D objects to a SimGroup. Since I'm counting on the SimGroup to delete the held fx2D objects when it is destroyed, I'm wondering if the held fx2D objects are necessarily being deleted safely with SimGroup's default deletion behavior?

Just wondering... :)

It should, but you could also do something like

if(isObject(theSimSet)){
  for(%i = 0; %i < theSimSet.getCount(); %i++){
   %obj = theSimSet.getObject(%i);
   theSimSet.remove(%obj);
  %obj.safeDelete();
  }
}

Yeah, that's sort of what I'm doing just to be safe. But there is one very large problem with your code -

Each time you remove an object from the beginning of a set or group, the remaining objects are scooted forward by one and %obj.getCount is decremented by 1. So, your code will only actually delete 1/2 of the objects contained in the set :)

Here's a much better approach -

for(%i = %set.getCount() - 1; %i > -1; %i--)
   %set.getObject(%i).safeDelete();

Or you could just delete the set after the loop =)
