I’m playing around with the ragdoll project @will put together to try and understand joints for another project I’m working on. As it stands, I’m getting an error saying joint.xform.getPosition() is not a function. The only reason for this I can think of is that joint.xform is being called out of scope, except in the original script it works fine.
Here’s the script with my changes:
var TestDoll = pc.createScript('testDoll');
// initialize code called once per entity
TestDoll.prototype.initialize = function() {
//var graph = this.entity.model.model.graph;
this.joints = [
{
bone: 'TorsoBone',
body: 'Torso'
},
{
bone: 'NeckBone',
body: 'Head'
},
{
bone: 'LShoulderBone',
body: 'LeftArm'
},
{
bone: 'LFunnyBone',
body: 'LeftForeArm'
},
{
bone: 'LWristBone',
body: 'LeftHand'
},
{
bone: 'RShoulderBone',
body: 'RightArm'
},
{
bone: 'RFunnyBone',
body: 'RightForeArm'
},
{
bone: 'RWristBone',
body: 'RightHand'
},
{
bone: 'RHipBone',
body: 'RightUpperLeg'
},
{
bone: 'RKneeBone',
body: 'RightLowerLeg'
},
{
bone: 'RAnkleBone',
body: 'RightFoot'
},
{
bone: 'LHipBone',
body: 'LeftUpperLeg'
},
{
bone: 'LKneeBone',
body: 'LeftLowerLeg'
},
{
bone: 'LAnkleBone',
body: 'LeftFoot'
}
];
for (var i = 0; i < this.joints.length; i++) {
var joint = this.joints[i];
joint.bone = this.entity.findByName(joint.bone);
joint.body = this.entity.findByName(joint.body);
joint.initPos = joint.body.getPosition().clone();
joint.initRot = joint.body.getRotation().clone();
joint.xform = joint.body.findByTag('Bone');
}
/*

};
TestDoll.prototype.reset = function() {

}

}

var joint = this.joints[i];
joint.bone.setPosition(joint.xform.getPosition()); //Error here
joint.bone.setRotation(joint.xform.getRotation());
}
};
