i'd try to explain as understandable as possible

i have box (top view)
++++
++++
++++
++++


when i shoot near left corner, box is moving by clock
->
++++
++++
++++
^+++


but when i shoot near right corner, box may move in another side, but he is still moving by clock
->
++++
++++
++++
+++^

maybe, this is trouble with mass matrix or someting like that?

try to use the trace direction instead of vectorf(-normal.x,-normal.y,-normal.z).

(and the origin of the model should be in the center of the cube.)

i had tried that
Code:

---

 
vec_diff(temp_vec2.x,temp_vec.x,camera.x); // temp_vec2 from camera to target
vec_normalize(temp_vec2.x,1); // lenth of temp_vec2 = 1
NewtonAddBodyImpulse(body_temp, vectorf(temp_vec2.x,temp_vec2.y,temp_vec2.z),
 vectorf(temp_vec.x * QUANTTOMETER, temp_vec.y * QUANTTOMETER, temp_vec.z * QUANTTOMETER) );
 

---

but the effect is similar

and the origin of model if exactly in the center(just because its your model crate.mdl )

i have idea....

for example, i have box:
[++++++++++++++++++++^++++++++]

so i may count distance from "^" to "]"... and add to vertex not all force, just a part of it... but, on the other hand, its not too important...

okay, that's really not too important:)
thanks)))

okay, going to materials...

so i have bullet
Code:

---

 
you = ent_create(bullet_mdl,my.x,0);
you.scale_x=.5; you.scale_y=.25; you.scale_z=.25;
vec_set(you.pan,my.pan);
you.skill99 = newton_addentity(you, 1, NEWTON_SPHERE, Bulletforceandtorque);
NewtonBodySetMaterialGroupID(you.skill99,bullet_nmat); 

---

and box

Code:

---

 
action box_weapon_test()
{
c_setminmax(me);
my.skill99 = newton_addentity(me, 15, NEWTON_BOX, onforceandtorque);
NewtonBodySetMaterialGroupID(my.skill99,box_nmat);
} 

---

and collision

Code:

---

 
NewtonMaterialSetCollisionCallback(nworld, bullet_nmat, box_nmat, 0, collided_ground, collided_ground2, collided_ground3); 
NewtonMaterialSetDefaultCollidable(nworld, bullet_nmat, box_nmat, 1);
 

---

collided_ground - just beeps 1,2 and 3 times



so, bullet collides with box and nothing changes and beeps...

i don't understand. when does it beep and when doesn't it beep? can you also show your callbacks?

hm... some materials are beeping, other - are not... i'd try to search solution in practical way and i'd write here, as i will get interesting results...

Quote:

when does it beep and when doesn't it beep?

---

it may beep all time, but sometimes(using different pairs of materials) i have no sound at all

i find!

Code:

---

 my.skill99 = newton_addentity(me, 15, NEWTON_BOX, onforceandtorque);
NewtonBodySetMaterialGroupID(my.skill99,box_nmat); 

---

this is bad one...


Code:

---

 
NewtonBodySetMaterialGroupID(newton_addentity(you, 1, NEWTON_SPHERE, Bulletforceandtorque),bullet_nmat);
 

---

this wokrs

hm... probably it's some lite-c quirk with how the pointer gets converted to the var skill. you could try to cast the pointer somehow. or use your method that works.
