Timeline Node Issues in UE5.4.4

Using simple Blueprint for a door. When I press ‘e’ the door should open making a 90 degree turn… But instead the door spins around 4 or 5 times really fast. I watched 3 different videos and out of the different setups for each blueprint non of them changed the out come.

Am I being a dummy, or is this an issue please let me know!

Timeline:

  • Float track
  • TG_PrePhysics
  • starts at 0,0 - ends at 1,1

The script is incorrectly set up:

  • you’re adding rotation every frame rather than setting it
  • you’re re-sampling the data during TL Update - a no-no as far as consistency is concerned; set rotator variables before you play the TL and only then Lerp between them
  • it seems you’ve implemented the input inside the door BP rather than inside the instigator - usually the Player Controller or the Pawn. The door does not operate itself, it’s the player who interacts with it, right?

All of the above needs addressing.
