This simple code works for me:

Code:


var ball_speed[3];

function ball_hit()
{
	if(event_type == event_block)
	{
		vec_to_angle(my.pan, bounce);
	}
}

action bouncingBall
{
	my.enable_block = on;
	my.event = ball_hit;
	
	while(1)
	{
		ball_speed.x = key_1 * 25 * time_step;
		ball_speed.y = key_2 * 25 * time_step;
		ball_speed.z = key_3 * 25 * time_step;
		c_move(my, ball_speed, nullvector, glide);
		wait(1);
	}
}
