We’ve got some stuff cooking on this, so please don’t take too hard a dependency on this, but I implemented a physics-enabled FPS controller as a proof of concept a few months back, if you want to look at that.
Input encapsulation experiment | Babylon.js Playground (babylonjs.com)
This approach includes gravity, jumping, sprinting, and interaction with both static and dynamic physics objects: you should be able to run into the big block, walk up/down the ramp, and knock over the stack of small blocks and push them around. Again, this is not final, so please take it with a grain of salt and know that we’ll be using it as a basis for some of the stuff we’re cooking up. 
But if you want to jump into how an FPS camera works, this might at least be interesting to look at. Hope this helps, and best of luck!
