Make object move with arrows

ok so im making a new game and I need help making the object move because im having a little trouble with it.Heres the link to it PlayCanvas | HTML5 Game Engine

Since your player’s model has a collision and a rigid body component, you can force the player to move by applying a force vector in the desired direction (up, forward, or using negative values to obtain other directions). As an example, you can use the official tutorial, only in your case you need to become attached not to the camera, but to the player’s entity.

Here’s another great project to check out, if you’re wanting to do 3rd person camera and movement:
