Well, i am not sure the problem its solved that way...
If you want try this code:

Code:

---

function ball_hit()
{
   if(event_type == event_block)
   {
      vec_set(my.skill1, bounce);
   }
}


action bouncingBall
{
   my.enable_block = on;
   my.event = ball_hit;
   vec_set(my.skill1,vector(12*time_step,8*time_step,2*time_step));
   while(1)
   {
      c_move(my,my.skill1,nullvector,glide);
      wait(1);
   }
}
