Get controller node actually just gets a reference to the player controller, and doesn’t do anything other than that on it’s own. What attaches your controls is this node and it’s inside of the vehicles player controller itself:
The reason I’d asked if it was receiving any of the input actions is if not, it could either have not been possessed at the start or this wasn’t setup in the player controller.
(assuming you’re using the default input actions) If you place a print node after one of them, for example IA_throttle here:
Does it print? If not, we need to verify if your car is ever possessed.
Putting this on your BP will print if you possessed the vehicle when it starts (it’s usually clear but you can always verify)
and does that print when the game starts?
If both of those print and the car doesn’t react, then we’ll have to debug the vehicle itself and that will get a bit more fun.
