In a side-scrolling game, the camera is attached to the character with a spring arm. Now, when the character is standing on a wall, the character’s gravity is perpendicular to the wall. I want to calculate and set the relative rotation of the camera or the world rotation of the camera using the character’s up vector or gravity direction. How should I write the blueprint? I’ve asked AI for a long time but couldn’t complete it. It seems that this is the only way to calculate it, as other methods would cause problems when the character turns around.
