Re: [Swarm-Modelling] world getObjectAt

[Paul E. Johnson]

I can't help unless you tell what exactly you did why/how it did not work.

But consider this:

id someThing = [yourGrid getObjectAtX: x Y: y];
if (someThing != nil)
{
    int certainAttribute = [someThing getCertainAttribute];
   if (certainAttribute == 1)
       {
            //move in a direction
        }
    else if (certainAttribute == 2)
      {
           //move in other direction.
   }
}

This presupposes your class  of objects has a method "getCertainAttribute"
