Old project. Please see my newer one: https://scratch.mit.edu/projects/54631830/ A crazy tool to draw a set of lines and/or bezier curves using only two sprites (minus the export button). Fullscreen and turbo mode (shift click the green flag) for best results! Click and drag nodes to modify the curves. Keyboard Controls: L: Add a new line Q: Add a new quadratic bézier curve C: Add a new cubic bézier curve Update 2014.17.09: New automatic resolution slider. Smaller arcs will have a lower resolution to save on rendering time. Set it to zero for the original constant resolution. Also, the export button now converts the curve into a single item, allowing you to copy/paste the data anywhere. Update 2014.05.09: Added sliders to control the pen size and color after I discovered a cool trick to input RGB values into the "set pen color to" block. Click the export button to convert the curve into a a list that can be saved as an svg file. You can also download the curve by clicking see inside and right clicking the list. Then change the file extension from "txt" to "svg" You can then open the file with a modern web browser to see the curve, and/or import it back into Scratch. The resolution of the curve can be changed by changing the "res" variable. A higher resolution will result in a smoother curve, but it will take longer to redraw. 15 seems to be a good balance between quality and speed.
