Thanks! In this demo, I used the "Advanced Locomotion System" for character movement, which by default has a button for manually switching between ragdoll and animated states. However, I disabled it for this demo because the focus wasn't on ragdoll play, and the ragdoll state often caused glitches and the character falling through the map. Instead, I opted for more controlled conditions related to ragdoll.
As for gamepad support, it is already included in the demo. My Xbox Series controller works perfectly fine with it and I think others should too. However, I don't have any DualShock controller, so I don't have the means to implement their support as I wouldn't be able to test it myself.
