How do I prevent camera jitter when rotating the player?

Question

This is a problem that seems to have no reasonable answer anywhere around, yet is a commonly needed aspect of developing game mechanics.

Context

I'm developing a traditional 3rd person character controller esque thing, you know, camera controlled by mouse/joystick all that jazz.

The issue comes when I'm developing a climbing system:

• I have to develop a climbing system, and when I 'attach' the player to a climbing ledge, they could be at any angle relative to this ledge, up to perpendicular.

• When the player jumps up, and the ledge detection runs, the player attaches to the ledge, and needs to rotate to be facing the ledge dead on.

• I need a method for the camera movement to be completely independent of this capsule collider rotation change, as currently I have this problem:...

Problem

When I rotate my player's capsule collider, the attached camera boom rotates with it.

---

Specific Problem

When I set my actor's rotation directly, the camera orients itself immediately with the player's direction, then immediately returns itself to the previous view, creating a massive camera jitter, especially at lower framerates.

The question

How do I prevent this behaviour

OR

How do I reapproach problems of rotating the player character?

Answer 1

I've had the same problem, and as @natalo77 said in the comments, switching to absolute rotation did the trick.

You need to select the parent of your camera (the camera boom), then in the transform, for the rotation, select "absolute rotation" for the rotation instead of "relative".

I kept the position vector at "location" so that the camera moves with the player.

then I guess you can use the "look at" function bewteew the camera and capsule to keep the player at the center of the screen.
