I'm attempting to make a rollercoaster with a restraint system to prevent players from jumping out of the seat when a button is pressed in the control room, and them being able to re jump out when the button is pressed again. Is there anyway to do this?
To prevent the players jumping simply set the Humanoid.JumpPower
to 0, and then once it's clicked again, change it back to 50. As you haven't provided us with code, it is not our job to make it for you. If you provide code next time after having a proper go at it, we can help you more.
If you're happy with this answer, please accept it as the answer to your question so people know. I'll be happy to provide code once you've had a go.
