So I have 2 things, 1 is my playercharacter, 2 is a wheeledvehiclepawn. I want to put a gas pedal actor in the vehicle that will take that input when my playercharacter intereacts with it and apply the IA_throttle to the wheeledvehiclepawn. any easy idea on how to do it?
Do you have any trouble implementing it? It seems simple enough. (It depending on what “interacts” means between the character and the pedal though)
The easy way to do it is to not do it at all 
Fake the whole interaction. Just control the vehicle and animate the pedal and the character as if they interact.
