I know in Character class that it can change Character movement Based on the camera, But AnyBody Know How to change Movement based on the camera for Pawn also.
Hey ,
Do you mean rotate based on camera, and get the forward vector based on the camera’s current rotation? The way to do this is to have everything rotate with the control. There are a few steps to set this up for a pawn.
First, we need to set up movement and rotation inputs. We can borrow from the third person template blueprint here. Note that vectors are being calculate from control rotation, not actor rotation.

Next, head to the spring arm component in your pawn. Set it to rotate with control rotation.
This sets your camera to spin around your pawn.
Finally, in the pawn settings, check which rotations you want to inherit from your control rotation. If you just want to turn left and right, just choose Yaw like I have here.
I hope this information helps, and good luck!
