Find out how to make an Extensive Scrolling Engine using very few scripts and only 1 sprite. With only the 1 sprite your background can still be as big as you want, and it will cause very little lag (if any) because only 3 pieces of the background are loaded at once. Navigate the terrain using the arrow keys, and feel free to implement this idea into your own projects.
If you would like to see more scratch projects like this one go to my studio - http://scratch.mit.edu/studios/477650/ And also check out some of my different projects @theonlygusti In my projects I want to explain and utilise simple, helpful mechanics that would be useful for other scratchers in their projects. I also aim to make my projects as simple and easy to implement as possible, so I work on cutting down the number and lengths of scripts required for functionality (I add a few extra scripts in my demonstration projects).
