Note: This repository is depreciated by the new Awesome Arcade Extensions website at https://awesome-arcade-extensions.vercel.app/.
This is a list of MakeCode Arcade extensions that I find super useful in my projects. If you would like to suggest an extension be added, please open an issue with a link to the extension on GitHub. Or even better, open a pull request for adding an extension! Make sure to include a description, import url, links to it's GitHub repo, GitHub Pages example if any, forum post showcasing the extension if any, and an entry in the table of contents!
You can find the old Gist here.
These extensions are already built in to the editor, all you have to do is go to the toolbox, open the Advanced tab, click on Extensions, and click on the extension you want to import!

The default sprite overlap and tilemap overlap blocks are called for every frame it is happening, which can lead to unexpected results.

Yes, this is about useful MakeCode Arcade extensions but these tools will level up your game-making experience!
This tool will convert your images (like .png files) to Arcade code! Simply copy the output, open JavaScript mode in your project, navigate to where you want the image block to go, and paste in the image code! You may need to remove some redundant characters. Remember that Arcade has a maximum image size of 500x500!
Find this tool here:
https://kristianpedersen.github.io/Convert-Image-to-MakeCode-Arcade-Sprite/
This tool will also convert you images to Arcade code, but it also supports using 16-color palettes, in case you don't want to use the default palette! Simply copy the output, open JavaScript mode, navigate to where you want the image to go, and paste away! You may need to remove some redundant characters. Remember that Arcade has a maximum image size of 500x500!
Find this tool here:
Have a bunch of images you want to send to someone, but they hate exercising their pinkie and pointer finger? This will convert a set of images into a MakeCode project that, when you import, will put the images into the image gallery! And as of December 2021, this tool has been updated to be even better than before, with support for animations, tiles, and tilemaps! (Forum post)
Find this tool here:
The ultimate Arcade image manipulator! Rotate and flip your sprites with this!
Find this tool here:
Stop drawing your title screen text by hand! With this tool, you can render any (well, any font on your computer and in Google Fonts) font onto a Arcade image with outlines and shadows!
Find this tool here:
@jacobcarpenter on GitHub has written a neat tool that scrapes the MakeCode Forum's arcade section and shows the games in a gallery-like view! So you don't have to suffer and scroll through debug programs and tons of comments to find that dang link. You can also view the most liked-games of all-time and by author, like me for example hehe.
Find this tool here:
I have written a Python script that will turn images and multi-frame GIFs into MakeCode Arcade images and arrays! Note that this tools requires at least Python 3.9 on a computer, and command line knowledge is highly recommended!
