How do you 'get' specific bones in a character skeleton via script.

Questions & Answers

Hello! How are you?

I would like to know more about targeting specific bones on a character model via script.

I have a character I am controlling with a dual-stick controller. The right stick walks the character around, while the left stick turns the upper body.

I know I can create a simple 'lookat' script and place it directly on the bone I want to turn (in this case, the first spine bone above the pelvis). However I would like to keep the character controls in a single script, currently located on the root node of the overall character, and simply call out to the correct bone from it.

I am a new programmer so apologies if this is more of a general programming question and not specific to Unity. I still greatly appreciate any help though! Thank you in advance!

Bones are just Transforms in Unity, so all you need to do is create a variable, then drag the correct Game Object onto the variable slot in the Inspector.

var bizzyBone : Transform;

You can then script anything you want with that Transform, and the Skinned Mesh Renderer's vertices that are weighted to that bone will go along for the ride (forward kinematics).
