bounce

bounce

Bounce off direction. When a c_move function generates a collision, this vector is set to the direction into which the colliding entity would bounce off the obstacle surface, and can be used to implement a bouncing behavior.

Type:

VECTOR

Modified by:

c_move

Remarks:

Can be modified anytime and thus won't keep its values during wait.
Algorithm: bounce = speed + 2*dot(normal,-speed)*normal, while speed = distance vector to target, normal = target surface normal.

Example:

action bouncer()
{
  while(1)
  {	
 	  c_move(me,vector(5*time_step,0,0),nullvector,0); // move ahead...
    if (trace_hit) { 
      vec_to_angle(my.pan,bounce); // and bounce off any obstacles
    } 
    wait(1);
  }
}
