   Hey all,
   So I know this is probably easy to do but i just cant figure it out. In my game I update all of my sprites and chipmunk bodies. They are all named the same except for a number. For example I have:

   player1Sprite
   player2Sprite...

   enemy1Sprite
   enemy2Sprite...

   and then i have the chipmunk bodies which are:

   player1Body
   player2Body...

   enemy1Body
   enemy2Body...

   Right now im going through and doing:

   player1Body->p = player1Sprite.position;
   	player2Body->p = player2Sprite.position;
   
   	cpBodySetAngle(player1Body, CC_DEGREES_TO_RADIANS(-player1Sprite.rotation));
   	cpBodySetAngle(player2Body, CC_DEGREES_TO_RADIANS(-player2Sprite.rotation));
   
   	enemy1Body->p = enemy1Sprite.position;
   	enemy2Body->p = enemy2Sprite.position;
   
   	cpBodySetAngle(enemy1Body, CC_DEGREES_TO_RADIANS(-enemy1Sprite.rotation));
   	cpBodySetAngle(enemy1Body, CC_DEGREES_TO_RADIANS(-enemy2Sprite.rotation));

   and

   [player1Sprite setPosition:ccp(player1Body->p.x, player1Body->p.y)];
   	[player2Sprite setPosition:ccp(player2Body->p.x, player2Body->p.y)];
   
   	[player1Sprite setRotation: (float) CC_RADIANS_TO_DEGREES( -player1Body->a )];
   	[player2Sprite setRotation: (float) CC_RADIANS_TO_DEGREES( -player2Body->a )];
   
   	[enemy1Sprite setPosition:ccp(enemy1Body->p.x, enemy1Body->p.y)];
   	[enemy2Sprite setPosition:ccp(enemy2Body->p.x, enemy2Body->p.y)];
   
   	[enemy1Sprite setRotation: (float) CC_RADIANS_TO_DEGREES( -enemy1Body->a )];
   	[enemy2Sprite setRotation: (float) CC_RADIANS_TO_DEGREES( -enemy2Body->a )];

   Now my question is can I somehow make the number an int and then create a loop that just adds one to the number?

   Thanks

   You can put the objects in two arrays where the positions are that same number. Or use 2 Dictionaries for it, using the number as the key.

   You can also create a object that contains both sprite and body. Then just call a update on those new objects that will in place fix the sprite position, rotation, etc.

   There are quite a few more options available, it all depends on your own requirements, i guess...
