In Unity, one of the first things you might end up doing for your game is trying to figure out why the camera seems a little stiff. There can be a lot more for a camera to do than just move positions or follow a character. You might want to apply some effects, such as a smooth following effect, to your camera so your game looks more interesting and your character gives off more of a moving effect.
To achieve such effects, you’ll probably want to use Linear Interpolation and Delta Time so make your camera change positions smoothly over a length of time. More details in the video. Hope it helps!
