   i want to change the layer of the shape randomly
   ....enum layers{
   Layer_1 = 1,
   Layer_2 = 2,
   Layer_3 = 5,
   Layer_4 = 6,
   Layer_5 = 12,
   Layer_6 = 14,

   };

   .///////
   shape->layer = Layer_+(1 or ,2,3,....);
   ive tried NSString *randLayer = [NSString stringWithFormat:@"Layer_%d", 1 + arc4random() % 6 ]; but i dont know how to combine them.

   Put the layer numbers in an array ( a simple C array would work ), then randomize the array index and use the value as the resulting layer.

   "Put the layer numbers in an array" Maybe putting the Layers themselves in an NSArray would be easier.

   @codemattic: I thought that chipmunk layers were just defined assigning an int. Otherwise your suggestion is definitly better.

   crap - sorry, I thought he was talking about cocos2d Layers. I must learn to read more closely before I reply!

   Still learing Obj-c , so here it is in C++
   

   enum layers
   {
   Layer_1 = 1,
   Layer_2 = 2,
   Layer_3 = 5,
   Layer_4 = 6,
   Layer_5 = 12,
   Layer_6 = 14,
   };
   
   layers choices[6] = {Layer_1,Layer_2,Layer_3,Layer_4,Layer_5,Layer_6};
   
   layers selection = choices[rand()%6];

   !Edit works with objects too, not just enums, just change the array type to something more useful.
