Moving a box in 3d space

Questions

Hi I need help with applying movement to an object, I want the box to travel in x, y, z position based on the direction it is facing (x, y and z rotations), can anyone help, I thought this would be simple but I cant find anything that works. anyone got a code or example of this?

Something here should Centered on Created Origin | Babylon.js Documentation.

A basic attempt in a playground even it it does not work would give us a basis to work from.

Heres a basic playground to work with. If I could just get movement based on the direction the blue box is facing id be happy. Im still confused by pivots etc.

Perhaps locallyTranslate is what you need.

Initial forward vector is (0, 0, 1), a unit vector, then

box.locallyTranslate(new BABYLON.Vector3(0, 0, 1).scale(speed));

gives a forward movement

I like what you did there, however I have another issue now, as I rotate the box the rotational movements go out of whack, ideally when I rotate the box 90 degrees to the left the pitch should become the heading change. Im not sure how to achieve this the best way, have a look at my playground and you will see the problem.

Thanks for the assistance so far though.

You guys are awesome.
