Hi @erey

I know a bit more about ammojs.There is an existing character controller that you can create and would fit your needs.  
There is this thread I found on the forum : [Handling Ammo Kinematic Character Controller](https://forum.babylonjs.com/t/handling-ammo-kinematic-character-controller/3528)  
A web search on ‘character controller ammojs’ will give you more results

Also, depending on your needs, maybe a physics engine is not the only solution. You can use a navigation mesh and constraint the player on that mesh. You’ll get more controls and visual feedback on allowed surfaces.

Check this thread for more details : [Constraining a UniversalCamera on a Navigation Mesh](https://forum.babylonjs.com/t/constraining-a-universalcamera-on-a-navigation-mesh/5042)
