 var RobotBlood : GameObject;
 var DeathRobotMode :GameObject;
 var DeathVehicleMode : GameObject;

 var parts : int = 16;
 
 //This is the skeleton function of the Player!
 function TransformerBones (Skeleton : BoxCollider) {
     if(Skeleton = BoxCollider);
   
   var RobotBodyBones : int = 35;
    GetComponent("RobotBones");
    }
 }
