Here's how to make a project continue, maybe do an exit animation or something similarly cool, when the user stops it. Go ahead, just click the green flag, then the red stop button and see what happens. This project makes use of the timer, so if you want to implement this idea into your own project you can't really use the timer elsewhere. Have a look inside to see how it works.
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).
