Is it possible to disable x & z rotation in ammo.js?

Question

Well, Is it possible to disable x & z rotation in ammo.js? (I want to create a FPS Player and I want to keep it in vertical position)

Answer 1

In bullet there is btRigidBody::setAngularFactor which takes a btVector3 as argument, where x, y and z corresponds to rotation along those axis. Use a 1 to allow motion, and 0 to disallow motion along a certain axis.

If you want to allow rotation only along the Y axis in ammo.js, use:

body.setAngularFactor( 0, 1, 0 );
