Custom camera...moving camera forward/backward at current rotation?

Recommended Posts


I'm building a custom camera controller using the CameraDirection and CameraRotation in order to preserve the inherent camera inertia. How the heck do I move the camera forward/backward using CameraDirection at the current Camera Rotation?

Not as efficient, but you can also do some one liners with Vector3 Methods (untested):

   new Vector3(Math.sin(camera.rotation.y), 0, Math.cos(camera.rotation.y)).scale(forward ? 1 : -1)

note: if you are building something to share, I think the Z needs to be inverse on right-handed scenes.
