In this episode I go over how to add camera controls using the mouse in our editor. This way we can move around the scene using the mouse and zoom in and out to move to different portions quicker. I also go over how to add a reset hotkey using linear interpolation (lerp), so that if you get lost in the scene you can always re-center the camera at the origin. The linear interpolation also makes sure that all the camera movement is very smooth.
