I specifically set jump power to 0, to force a player to stay in a seated position. allowing me to have a player’s character model, but without the character physics. ever since the latest update, a player in my game could jump and break my game because of this.
A workaround for this is to set the Jumping state to disabled with SetStateEnabled. I just tested it and this prevents the character from being able to jump out of the sit position.
You can also set their humanoid state to Physics with ChangeState.
