Parallax scrolling


As we are creating an endless runner, we need our environment to seamlessly repeat infinitely. There are various ways to do this; however, with the new Unity 2D animation, we can simply use the 2D animation to accomplish this by animating the background moving.

To do so, we need to do the following:

  1. Add a folder named Background to Assets within the Project Browser.

  2. Download and unzip the desert_BG.png image from http://freeartsprites.com/free-art/endless-runner/.

  3. Create a sprite GameObject using the following image:

  4. Make a duplicate of the image by pressing Crtl + D, and position it on the right-hand side so that they are seamless.

  5. Change the camera aspect ratio to 16:9.

  6. Ensure that the left-hand side desert_BG object fits perfectly within the camera view.

  7. Drag the right-hand side desert_BG object in the hierarchy onto the left-hand side desert_BG object so that the left-hand side object is the parent.

  8. Now, select the left-hand side object, and open the Animation View:

  9. Go to Window...
