Odd camera behavior #4

Closed Lemonzyy closed 1 year ago

Lemonzyy commented 1 year ago

I noticed something strange when I tried out the camera of your crate. The camera seems to roll without pressing the corresponding keys, but only by moving the mouse cursor.

As you can see in the video (example demo), when I move the camera using the mouse, the spheres that were previously aligned horizontally become aligned vertically, proving that the camera is rolling.

Yup, this is because the camera just applies rotation relative to the current transform. As you move in an arc, you are applying a rotation. This was done to avoid gimbal lock and the need to have an "up" direction. There might be a way to reconcile this.
