Hi everyone! I am fairly new to UE and coding in general and I’ve run into something I can’t seem to figure out. I am using blueprints. So, I have a ball which I am moving using torque. (Specifically, the Add Torque in Radians node). I have set up a third person camera which can rotate around the player. The issue is that the torque is being added relative to world coordinates. Because of this, when I am looking at the face of the player, I am still moving forward relative to the world. I would like to figure out how to add torque to the x and y coordinates which are relative to the direction which the player is facing. How should I approach this using blueprints?
Any help would be appreciated!

Hey @Fafarlando, welcome to the forums!
So from what I’ve understood from the question, it seems like you want to move forward in the direction the camera is facing, right? I think the best way to achieve this in blueprints is by using the node Get Camera Rotation, and I believe the initial target is the player camera. Then I would add the torque to the ball based on the camera’s rotation.
I hope this can help you out, and let me know if you need more help!

Thank you!
So the issue is with the torque being applied in a linear way if that makes sense. My mesh is a head and it keeps rotating, however the force does not take into account the x y z coordinates of the component. That’s what’s confusing me. I’ll send screenshots of the way the BP’s are set up.

To roll in the head’s forward direction with torque, you’d use its Right Vector. Some examples here:

If you want to roll the ball head in the camera’s direction, use the camera’s Right vector (or its springarm’s - depends on how you set it up). Namely:
