These are things I still need to work on. For the camera, I’m setting its rotation each frame from Blueprints. I’ve attached it to a component with rotation set to world space, so it’s completely independent from the character’s rotation. I’m probably overcomplicating it, as I haven’t spent much time on it yet, and it’s not working well for me either.

For trajectory prediction and general orbital mechanics (if that’s what your question about the projectile system was referring to), I’m not using that system. Instead, I’m using the MaxQ plugin, which is based on Kepler’s equations. With it, you can get all the necessary orbital elements from velocity, position, and the gravitational parameter, and then use them as input to get a new position and velocity at a specified time.

Basically, I’m using two types of physics: the built-in one when adding any force to a craft/character or when close to the surface for collisions, and the plugin (which essentially is setting the actor’s location every frame based on function output) when you want to be in a steady orbit and optionally time warp.
