Unity3D SpriteMask & Infinite Scrolling Background
The SpriteMask component in Unity3D 2017 makes it easy to show a sprite through another’s alpha channel. In this video, I go over the steps required in two minutes.
Once you have the SpriteMask setup, we can make the window scroll infinitely along.. giving the feeling that you’re riding on a high class train.
Here’s the video showing the steps required.
I found the background image on OpenGameArt.org here: https://opengameart.org/content/seamless-hd-landscape-in-parts
The train window came from a google image search here: https://www.google.com/search?q=train+window&tbm=isch&source=lnt&tbs=ic:trans&sa=X&ved=0ahUKEwjy_6nY0c3VAhVG8WMKHR82B2IQpwUIHw&biw=2048&bih=1137&dpr=1.25
