Hi, thanks for your reply. Unfortunately I still couldn’t get it to work so as a test I set up an actor ping ponging 200 along Y at a duration of 10, then set up a key press to change the duration to 2.
The actor ping pong’s and the key press fires the print string with the 2.0 duration but the actors movement speed doesn’t change, wondering if it is a bug maybe. I’m working with 4.13.
