How to get a character to open a door using animation

from what I have understood when replicating this guys code it seems that the lerps control the position of the character, teleporting him to the front of the door, where he will need to be for the animation. Then it calls the animation. I kinda don’t get what you mean with 2. I’m not too sure however I’m assuming the timeline is controlling the lerps teleportation in some way that I don’t quite understand. Also if it was calling it every frame wouldn’t the door animation also not play.

Just so you have a reference on the UE4 project that I’m working off, you can install his file if you want and see what he does in it.
