couldn't you detect ant encounters in the if-check below? If the
position to where an ant tries to move to is already occupied by
someone, you could check the type of the element in that position, and
according to that, implement the suitable actions (exchange
food/walking direction).

Hope it helps (But I think I'm missing your point...)

         xPos = newX;

         [world putObject: self atX: newX Y: newY];
