if parameter VelocityMagnitude is used, you can observe it acting differently when observed locally, and remotely as another player.
Basically, VelocityMagnitude should be a float that goes up with how fast a player moves. Locally, it will ONLY change when you use the movement stick on the controller.
But remotely, the number will change with both the stick movement AND full body movement, causing wildly different results from what each player sees.
