Unpossessed advanced vehicle continues input no matter what

If an advanced vehicle is unpossessed while a movement key is held then it will continue moving even if:
Input was disabled when the vehicle is unpossessed
“Throttle” variable was set to 0.0 when the vehicle was unpossessed.
@Burgess, can you look into this?

Hey Cowhunter,

It looks like the stop all movement node doesn’t work with this type of pawn which may be a bug. Thank you for submitting this post. I have reproduced this issue and logged a report for it here: Unreal Engine Issues and Bug Tracker (UE-40078)

You can track the report’s status as the issue is reviewed by our development staff. Please be aware that this issue may not be prioritized or fixed soon.

I was able to get around this by blocking the input axis move forward using a custom event.


Then I set the throttle input to 0 and had to delay before unpossessing the vehicle or else it didn’t work.



  1. Create an AIController which does nothing but set the throttle of the controlled vehicle to 0 (in the tick)
  2. Unpossess the car from player controller
  3. Possess the car by your new AIcontroller

It seems that the movement component only receives the previous to the last throttle input. And after being unpossessed it ignores inputs.

It’s still not working in 4.16.2 even if marked as fixed.
