Instructions: • Turbo Mode for best performance. • Click to add a point to your polygon. • Left arrow key to undo. • Press "Save" to get the save code for your drawing. Copy this. • Press "Load" to paste in a save code and render that drawing. How It Works: There is a list called "PenData" and whenever you click, your mouse coordinates are added to that list. It then runs a custom block script that reads the coordinate pairs in that list. The sprite goes to those coordinates in order, redrawing the polygon whenever you click. When you undo, it simply removes the last pair of coordinates from that list and runs the custom script to redraw your polygon again. When you save, it takes the whole PenData list, separates the coordinates with spaces, and adds it to the first entry on the "Save" list, so you can copy it to the clipboard. When you load the save code, it separates the coordinates into items on the "PenData" list and draws the polygon.
