I meant lines 73 and 74 in MyWorld. Aren't these the lines that should restore red team into the world?

The addedToWorld method should do that (in the actor, B, class). Your world only need add one as normal.

if(b>0 && --b ==0) addObject(new B(counter),r,r2); if(b==0 && getObjects(B.class).isEmpty())b =99; Can u add code to check collision using this code Becaz i only want b to add randomly (only in place of r and r2) If r and r2 place is full then it will check collision and add again to the world

If you add actor at (r, r2), then the addedToWorld method as given by RcCookie will try to find some empty place for it ONLY IF it is touching another actor,
