I'm having a problem....i have a ball which iv got behaving as such, so it collides with walls/models/pink elephants and bounces....great....but i need it to gain speed when it collides with anything. iv been trying for the last couple of hours and i cant get the phent_addforceglobal etc to work. i used the code in aum25 as a starter but to save anybody time, heres the code.

Code:

---

 
function create_ball()
{
	if ((balls < 1) || (ball_ptr != null)) {return;} // ran out of balls -> stop
	ball_ptr = ent_create(ball_mdl, ball_pos, init_sphere);
	balls -= 1;
}


function init_sphere()
{
	phent_settype(my, ph_rigid, ph_sphere); // enable physics for this ball
	phent_setmass(my, 100, ph_sphere); // the ball has 1kg (2 lbs) and behaves like a sphere
	phent_setfriction(my, 0); // friction
	phent_setelasticity(my, 100, 0); // bounce a lot
	temp.x = 0; 
      temp.y = -250; 
      temp.z = 0; // earth gravity factor, g = 9.81 m/s2
	ph_SetGravity(temp); // set gravity
	while (my.z > -150) {wait (1);} // the ball has approached the floor
if (EVENT_TYPE == Event_impact)
{
	temp2.x = 0;temp2.y-=100;temp2.z=0;
	ph_setgravity(temp);
}
 wait(1);
}

any help would be mega appreciated.

Negioni.

I think it is the way you are calling the event

Code:

---

function init_sphere()

{
my.enable_impact = on;	
my._event = bounce_event;
....
}

function bounce_event()
{
	if(event_type == event_impact)
	{
		//addforce along the BOUNCE vector here or you might want to wait a frame to make sure the ball has already changed course and then just boost it in that direction.
		//experiment)
	}
}

Almost right, but physics collisions are EVENT_FRICTION.

Code:

---

function init_sphere()

{
phent_settype(my, ph_rigid, ph_sphere); // enable physics for this ball
	phent_setmass(my, 100, ph_sphere); // the ball has 1kg (2 lbs) and behaves like a sphere
	phent_setfriction(my, 0); // friction
	phent_setelasticity(my, 100, 0); // bounce a lot
	temp.x = 0; 
      temp.y = -250; 
      temp.z = 0; // earth gravity factor, g = 9.81 m/s2
	ph_SetGravity(temp); // set gravity
my.enable_friction = on;	
my._event = bounce_event;
}

function bounce_event()
{
	if(event_type == event_friction)
	{
          //phent_addglobalforce here
	}
}
