Refer to my older project for more info. You can use this without credit (No credit required) Yup, you can only edit it using code, though you can easily add drag-and-drop points to control the line. Basically I created a new one because the old one was quite useless cuz creating curves with infinite points is quite annoying and most vector editors use cubic bezier curves in somewhat a chain (you can refer to scratch's built in editor itself), rather than a single, infinite-control-point curve, cuz it's easier to manage. Now, you could just modify the previous one but I wanted to get rid of all the lists and variables for extra speed, and so that people don't end up with 2 lists and 6 extra variables in their block palette, this one does it all with 1 variable and no lists, and 1 extremely wide script. The only limitation is that you can have only 4 control points. K so i've seen all sorts of projects that attempt this, but some (but not all) use lists for some reason, which isn't really required for bezier curves with a fixed number of points, unless you want it more organized, and that just slows the project down. instead you just put all that code in one line, and what you have is a rather fast bezier curve that does not fill your block palette with lists and variables.
