So, many people have wanted a block that triggers scripts by clicking the Stop Sign instead of the Green Flag. However, this has not been implemented since the Stop Sign is meant to stop the project instead of triggering other scripts. It is, however, still possible to do so. This tutorial will show you how in four basic steps! Use the left and right arrow keys to change slides. You can press M to toggle the music. You can also go to the next slide with space.
All the graphics (except my icon) use vector. ^_^ Thanks to @sirstef for suggesting this tutorial! The music for the project is "Prelude" by TheFatRat. Have any questions? Feel free to post it in the comments and I'll try to answer them! Also, if you already know how to do this, please don't comment that you already know how to do this, OK? I'm providing this tutorial for those who do not know about this technique.
