Most information is displayed in comments inside the project. Running it in turbo mode produces the best results. When you click the green flag, you see an example of a sprite moving from the x position -200 to 200 using the "cubicBoth" tween. When you press space, you see a circle shrinking from 200% to 0% size using the "outExpo" tween.
Original functions by Robert Penner. Ported to Scratch by jeffreynaydin2003 and KasserX20. The purpose of this tool is to provide with more smooth and customizable movement to sprites using math. The current "glide" block is only linear, and usually other tweens in Scratch are linear as well. This tool is to provide with a very versatile and easy-to-use custom block with most of the work already done (even with a built-in error detector, though that's still WIP). There are a few issues that will be addressed in future updates but currently I am happy with what we've done so far! OCTOBER 25 2021 -Added a few fixes to the script repeating when it shouldn't and some imprecisions. A lot of blemishes are being unveiled in this tool, so while this idea could have a lot of potential I don't really see it working that well outside of a vacuum.
