thank you so much!! now it works... great

i am so happy that i have polygon collisions now. thats absolutely great!

i have one question left (maybe not the last) but when i remove the entity, i guess i have to remove it from newton, too?? how do i do this?

NewtonDestroyBody()

you additionally could use NewtonBodySetDestructorCallback() to set a function which gets called when you use NewtonDestroyBody(). in the callback you could do the ent_remove() and other cleanup things if necessary.

now my function looks like this:
Code:

---

void erdbeere()
{
	NewtonBody *body;
	c_updatehull(me,0);
	set(my,POLYGON|FLAG2);
	while(my.z>-50)
	{
		wait(1);
	}
	NewtonDestroyBody(nworld, body);
//	ent_remove(me);
}

---

this however leads to an engine crash with no further explanation

btw, how do i setup such a Callback? Never did this before

hm... in your function you don't create the body? newtondestroybody() will crash if you don't pass a valid body.



you know how callbacks work from ent_create() for example.

function mycallback()
{
}

ent_create("model.mdl", nullvector, mycallback);

it's just a normal function. the pointer of this function gets passed to ent_create() and ent_create() will call that function then.

many newton features also work with callbacks.

oh, thanks.. i now use this function and it works:
Code:

---

void erdbeere()
{
	NewtonBody *body = newton_addentity(me, 10, NEWTON_CONVEXHULL, onforceandtorque);
	NewtonBodySetVelocity(body, vectorf(0,0,-5));
	c_updatehull(me,0);
	set(my,POLYGON|FLAG2);
	while(my.z>20)
	{
		wait(1);
	}
	NewtonDestroyBody(nworld, body);
	ent_remove(me);
}

---

thanks again for your help

me again...

now i want to add a random force or torque to the entity and was using this:


NewtonBodyAddForce(body, vectorf(random(100)-50,random(100)-50,random(100)-50));

or

NewtonBodyAddTorque(body, vectorf(random(100)-50,random(100)-50,random(100)-50));

but nothing changes. also i dont get the idea about how to have the entity with a certain start rotation

ok, now i used NewtonBodySetOmega and that works. Guess i'll search for a general newton manual now

yes, thanks very much ))
i really forgot about QUANTTOMETER

that works just great!!!

Code:

---

 
if (c_trace(camera.x, temp_vec.x,IGNORE_ME|IGNORE_PASSABLE|IGNORE_PASSENTS) > 0) 
{					
if (you.skill99!=0)
{
vec_for_vertex(temp_vec.x,you,hitvertex);
body_temp=you.skill99;
NewtonAddBodyImpulse(body_temp, vectorf(-normal.x,-normal.y,-normal.z) , vectorf(temp_vec.x * QUANTTOMETER, temp_vec.y * QUANTTOMETER, temp_vec.z * QUANTTOMETER) );
}

but box is rotating only in right side... i dont think that its famous error, but maybe you get this before?

please explain what you want to achieve in more detail.
