I need my cart to roll forward at a fixed speed when players aren't touching the cart but when they are pushing the cart the speed should return to the usual pushing speed such as 0.55 for 1 person. I've made an attempt myself by modifying the rollback so the OnTrue output makes the cart move forward at 0.1 instead of -1. OnFalse still sets the speed to 0. I have a 2 track_paths both control the value of the roll forward branch. The problem is that OnFalse doesn't work at all. Sending a value of 0 does not stop the cart. Either this is the wrong way to implement such a feature or I've messed up. Does anybody have any other ideas on how to do this?
