How would I partake in doing such work. Say I have my normal emiter:

Code:

---

 if(weapon_number==1)//////
	{
ent_vertex(temp,765);///vertex shell
CREATE <case.mdl>,temp,Part_shell;
} 

---

Now i got my Shell code where it does the normal random flips out of the case. How could i add physics to this...im thinking on using newtons.

Code:

---

 function Part_Shell()
{
my.passable = on;
my.metal = on;
my.scale_x *= 0.4;
my.scale_y *= 0.4;
my.scale_z *= 0.4;

// throw part
my._speed_x = random(6) - 3;
my._speed_y = random(6) - 3;
my._speed_z = random(3) + 8;

//reset:
my._aspeed_pan = 0 + random(20);
my._aspeed_tilt = 0 + random(70);
my._aspeed_roll = 0;

MY.PAN = YOUR.PAN;
 	MY.TILT = YOUR.TILT;

//Animate
my.skill9 = 20 + random(50);

while(my.skill9 > -16)
{
move_mode=ignore_models;
	abspeed[0] = my._speed_x * time;
	abspeed[1] = my._speed_y * time;
	abspeed[2] = my._speed_z * time;

	my.pan += my._aspeed_pan * time;
	my.tilt += my._aspeed_tilt * time;
	my.roll += my._aspeed_roll * time;

	vec_scale(absdist,movement_scale); // scale absolute distance by movement_scale
	move(my,nullvector,abspeed);

	if(bounce.z)
	{
		my._speed_z = -(my._speed_z/2);
		if(my._speed_z < 0.25)
		{
			my._speed_x = 0;
			my._speed_y = 0;
			my._speed_z = 0;
			my._aspeed_pan = 0;
			my._aspeed_tilt = 0;
			my._aspeed_roll = 0;
		}
	}

my._speed_z -= 2*time;
	my.skill9 -= 1;

	//fade out:

	my.alpha -= 2*time;
	if(my.alpha <=0)
	{
		//remove
wait(1);
remove(me);
		
		
	}
	wait(1);
}

}

Any ideas...i want it to bounce on ground i can call a sound....and then remove(me);

Thanks.
