Ragdoll Bone Physics system [OPEN SOURCE]

but can be used for any rigidbodies. decided to make this opensource

make a ragdoll, you’ll have the character joints (bones) with rigidbody weights

I found it to be for 100 rigidbody mass 980 is the force up which keeps it up in air
Im using AddRelativeForce with my controller, so it might be different
hopefully something will be added along the way

//forcebutton.js

var hipjoint : Transform;

var forceup : int = 1000;
var forcefwd : int = 1000;

var forcelHandY : int = 0;
var forcelHandZ : int = 0;
var forcelHandX : int = 0;

var forcerHandY : int = 0;

var FrFootX : int = 0;

var FrFootZ : int = 0;


function Start () {
}

function FixedUpdate () {

chestjoint.rigidbody.AddForce (0, forceup, 0);

if(hipjoint!=null) hipjoint.rigidbody.AddForce (0, 0, forcefwd);

if(rHand!=null)rHand.rigidbody.AddForce (forcerHandX, forcerHandY, forcerHandZ);
if(rShoulder!=null)rShoulder.rigidbody.AddForce (FrShoulderX, FrShoulderY, FrShoulderZ);
if(lHand!=null) lHand.rigidbody.AddForce (forcelHandX, forcelHandY, forcelHandZ);
if(lShoulder!=null)lShoulder.rigidbody.AddForce (FlShoulderX, FlShoulderY, FlShoulderZ);

if(rFoot!=null)rFoot.rigidbody.AddForce (FrFootX, FrFootY, FrFootZ);
if(lFoot!=null)lFoot.rigidbody.AddForce (FlFootX, FlFootY, FlFootZ);

}

ok. I took this a step further.

I think its good to call addforce in functions in this.

hip 20 chest 15 limbs 10-10 head 5
