Quickly saw this post and remembered me of this quick PG I did: > [@Stairs Collision Tester - A PG to test non-physics collisions](https://forum.babylonjs.com/t/stairs-collision-tester-a-pg-to-test-non-physics-collisions/35959): > > Dear fellow BJSers, I’d like to present here my first-version PG of a utility tool to quickly test on simple camera collision (non-physics) in particular in regards to climbing stairs or even simple small meshes like planks or small rocks. It appeared to me that the simple mesh collision with the ellipsoid of the camera does not provide a satisfactory result when climbing on small objects and is even worse when climbing stairs. Due to the 90° collis… Might be of use to you? Else, as per using or not using a physX engine and for what purpose, this is very much depending on your scope. Of how much importance, precise collisions are essential to your project (for collisions) but I suppose moreover, whether you have other features that require physics (like i.e. shooting, object with a mass, objects that require to transform or move with an imposter, etc…). As shown in the PG, you do not necessarly need havok to move and collide a character along the map. The rest, as I said, is really depending on your scope and expectations. I hope this will help you make a decision and meanwhile, have a great day 🕶 --- _[View the full topic](https://forum.babylonjs.com/t/what-is-the-best-way-to-move-character-on-stairs-up-and-down-while-the-camera-is-child-of-the-character-following-behind/49870)._
