Click the red "Record" button, then draw on the stage. Then click the green "Play" button to play your drawing back!
I chose to explore the pen tool blocks today, since I had never used them before Getting Unstuck and was excited to get more practice with them! In particular, I was inspired by @PinkyPepper's idea in the comments of https://scratch.mit.edu/projects/412237814/ to write a project that "recorded" drawing on the Scratch stage and then could play back that recording to simulate drawing. So this project is my attempt at that idea, using the pen and some list blocks I hadn't used before. I learned a lot this project, including - Scratch doesn't have an automatic triangle creator! You have to either draw all the edges yourself as lines, or remove one of the corners of the rectangle. - Lists have a maximum length, but it's high enough that for the most part I don't really need to worry about the maximum. - Recording every time the mouse is down misses out on a lot of pixels when the mouse is in between cycles of the loop: drawing a line to connect those points ends up being necessary to create continuity. - Scratch's synchronicity makes it so that a broadcast is fast enough to interrupt a forever loop after a single iteration, without multiple iterations that might create unexpected results. - Global variables can be used as a substitute for broadcasting, by waiting for a global variable to change to a particular state. Thank you to everyone in Getting Unstuck for all of your projects these past two weeks! I've had so much fun and I'm going to miss this. Special thanks to the facilitation team too, for making this all possible. And thanks to everyone who watched my first-ever YouTube stream today as I tried to talk through my process for working on this!
