Ok, I'm currently working on some things frequently seen in pinball games
First, a bouncer (like, on touch it bounces you(phent ball) away.
Right now, the bouncer entity (a sphere, placeholder) rotates so that its facing the player on impact but I just cant get the actual push to work correctly >_<
Code:

---

 function event_bounce() 
{
if (event_type == EVENT_IMPACT ) 
{
  vec_set(temp,player.x);	
  vec_sub(temp,my.x);
  vec_to_angle(my.pan,temp); 

	phent_clearvelocity(player);
        // this part isnt working right :((
	//phent_addvelcentral  (player,my.pan ); //schieben
	phent_addvelcentral  (player, vector(my.pan, 0, 0)); //schieben

	return;
}
} 

---

I messed with that for quite some time and I can somehow get it to bounce the player away but the direction it pushes the player to is always [censored] up and never quite right


So now for my second problem
I want to make a function/event that, when the player collides with another phent (another ball in this case) creates a force at the exact impact location so it pushes both balls away. I was thinking about scanning for the nearest vertex where the impact happened but I have no real idea how exactly I should do this :s

Any kind of help or hint would be appreciated

Merry Xmas

y don't u just attach a constraint to the bumper and use the physics functions for adding torque.

aren't constraints only used to limit the degree of freedom for an object (like, an arm cannot rotate 360° in all directions)
Sorry I'm a poor artist who's new to programming ^^

..Sorta, yeah. If you added a hinge constraint to the bumper, then it could only rotate along the z axis.

Hmm, that wouldn't solve my problem I think.

Rotating the bumper to face the player isn't the problem, but to add a force to the player along the bumpers pan axis

..so .. confusing...

...Thats what using physics does. The force unto the player is done by the physics engine

duh.. off course
My problem with the bumper is "just" applying either velocity or torque (or both) to the player into the direction of the bumpers pan

While writing this, I had another idea and quickly tested it out
if I use

phent_addvelcentral (player, vec_scale(my.pan, 50));

it seems to work more or less. for some reason it only bounces the player away in 3 of 4 impacts

Got no real ideas yet about the two colliding balls problem though.
