Small problem in Ragdoll code(orientation of Player) - 11/18/09 21:21

HI,
Since my last try for a ragdoll code, i have changed some things.
This is the code used to rotate a bone according to its physic bonde:

Code:

vec_set(ang_b.pan,parent_ent2.pan);
	str_cpy(source_bone,source_bone_input);
while(ent.skill1 == 0)
	{
		ang_diff(ang_a.pan,parent_ent2.pan,ang_b.pan); //calculate difference between old and new rotation of the physic-bone
vec_set(ang_b.pan,parent_ent2.pan);            
ent_bonerotate(ent,source_bone,ang_a.pan);//rotate the anim-bone by the angular difference we got 2 lines above	
wait(1);
}

This is working as long as the mainbody's orientation(this hinge is connected to) is (0,0,0). How do i use now the orientation of the main body to calculate the correct angles?

As you can see, the bonemovement of the anim-bone and the physic-bone is fitting...but only as long as the main body(the big white block) has an orientation of (0,0,0). I know i have to use its orientation in my code but untill now i couldnt get it to work(maybe iam too tired).

I think until now, i did everything correct this time(ok still need to calculate with the main bodies orientation)

NAd yes i seacrhed through the forum,(and my old topicy) but couldnt find a solution for the thing iam imagine

.

Maybe someone can give me a hint to add the calculation of the mainbody.

EDIT: i think i have to subtract the angle of the mainbody from the rotation of the physic-bone to get the local rotation right? And it hink i have to use matrices? But how?

create your ragdoll as if it had no rotation to setup the hinges properly, and apply post-rotation to the whole body.

later on you want to place the position of all objects on the position of the bones for blending animations anyway...

that's how I used to do it

No,i meaned,when they body changes its orientation while acting like a ragdoll.
I didnt mean the startup.. The startup is currently always (0,0,0).

Iam not able to translate the global rotation of the Physic-bone to local rotation of the bone(if the orientation of the visible mesh is not (0,0,0) ).

just read the angles of the hinge constraints and then rotate the models bone animations. Hinges are local values, and so are bones, you're doing unnecessary work.
