Get Left Vector of Target Object in relation to active Camera

[Pryme8]

 

So I know how to get the forward vector:

var forward = scene.activeCamera.position.subtract(gameSettings.playerObject.position).normalize();
forward.y = 0;

but how does one go about getting the left vector?
I can apply an impulse playerObject.applyImpulse(forward.scale(-0.05), playerObject.position);   

and effectively push the object away from the camera, but how would I "push" from the left of the object or the right of the object in relation to the camera?


***EDIT***

I thought about it and it dawned on me... cross the up vector of the camera with its direction...
 

var forward = scene.activeCamera.position.subtract(gameSettings.playerObject.position).normalize();
				
var right = BABYLON.Vector3.Cross(forward, scene.activeCamera.upVector).normalize();
right.y = 0;

Correct!! A simple cross can make it
