Not sure this is my fault or something else, but it's happened a few times that when players join my game, instead of walking with a walking animation, they just start sliding around the map. This was visible to the player themselves and to me as well.
Any ideas on what causes this? Here's a 10 second screen capture: https://youtu.be/gUuoVXNWLK4
Maybe it's just packet loss, with the packet containing the animation change getting dropped and only the movement packet coming through?
I don't have any scripts that would alter player behavior like that. The only thing I have that I can think of as possibly being related is an official example script that puts players in a collision group such that they cannot collide with each other.
Make Your Animation Priority Movement I Think?
Had a similar issue when testing my game - The fix for me was ensuring that my spawn point was NOT below the surface of the terrain. It seems like game start takes the spawn location literally and had half of my character stuck in the terrain and constantly sliding. Hope this helps
Check if the part your standing on has velocity to 0, 0, 0.
