Getting Obj from World Manager
Hello again,

im trying to use Game::World.objGet to check for objects in range.

Code:
Memp<GameObject*> objs;
      ..
      ..
      ..
      Game::World.objGet(objs,Ball(radius, T.pos()));

can anybody explain me how the Memp init works?
thanks in advice

There are some tutorials using objGet, probably Bloody Massacre

thanks greg
I get it working but i am only able to get Game.Obj types.
i want to get my subclass from Game.Obj cause it has actor and so on..
are there more ways?

what would be the best way in performance to iterate through objects?

You can use dynamic_cast (like the CAST macro).

That's also covered in the Bloody Massacre tut:

Code:
void autoPickUp() // automatically pick up nearby items
   {
      Memt<Game.Obj*> obj;
      Vec test_pos=ctrl.center()-Vec(0, ctrl.height()/2, 0);
      Game.World.objGet(obj, Ball(2, test_pos), OBJ_ITEM);

      REPA(obj)
         if(Item *item=CAST(Item, obj[i]))
            if(item.type==ITEM_WEAPON && item.mesh && Dist(test_pos, item.mesh->box*item.matrixScaled())<=ctrl.radius()+0.1f)
      {
         AddMessage(S+"Picked up "+item.name);
         itemPickUp(*item);
      }
   }
