I was following this course using UE5 version 5.4.2 and building a "Handle Rotation" graph for a door that looks like this:

I encountered this problem: setting the Interp Speed to anything but 0 makes the Return Value wrong.

I mean that, as I understand FInterp, it should eventually return the Target value, but in my case interp speed just makes the value wrong.

For example (Current = 0, Target = 90, Delta Time = World Delta Seconds, Interp Speed = 3) the return value of this is equal to 0.375.

I used event tick to set the delta time but it changes nothing.

Just setting the speed to 0 makes it work, but that is the problem, I want smooth rotation for my door.

I can't figure this out. My obstacles have a basic box collider on them and my player has a rigidbody based controller and collsion detection is set to Continous and when obstacle hits him it just passes trough the player. Belowe is my player rigidbody and collider settings

Update:

Ok so I found out the following things: Player do seem to react a little when I add a rigidbody to the obstacle, set it to kinematic with continuous collision detection, and I increase player size (this is the most important change). Still it only moves slightly and obstacle passes trough the player.

I would like to show race progress in my UI. My minimap is like sketch below:

Blue dot represents progress and red dot is finish line. I would like this to work in UI so only blue dot would move. If it was circular or linear I think it wouldn't be much of the problem but I am not sure how to move the dot with this shape.
