Casual game editor using Microsoft MakeCode Build Status

This repo contains the Arcade editor built with Microsoft MakeCode (PXT).

Creating and editing a package

In the editor, you will find a GitHub icon next to the save icon. Use the GitHub integration to build a library package. You do not need to install the local dev server; everything can happen in the editor.

Local server setup

This setup gives you a local version of the editor and the ability to load packages from your machine. This is the setup to develop new packages.

Setup

git clone https://github.com/microsoft/pxt-arcade
  • go to pxt-arcade and run
cd pxt-arcade
npm install

Don't forget to periodically git pull and npm install to get the latest changes.

git pull
npm install

Launching the server

This command launches a local web server. Note that this web server is meant for development purposes only. It was not designed or secured to be run on a web server.

npm run serve

Refreshing the community.md file

Run this command, then patch description, improve the screenshot (or record gifs) if necessary.

pxt ddt featured-game --md docs/community.md

This command requires ImageMagick (https://imagemagick.org/index.php) to be installed and available at the command line as "magick".

Updating pxt-arcade-sim version

When changing the version of pxt-arcade-sim referenced by pxt-arcade, you need to change the version in three places:

  1. package.json
  2. .github/workflows/pxt-buildmain.yml
  3. .github/workflows/pxt-buildpush.yml

In the two yml files, you'll find the version in the ref field under the step that checks out pxt-arcade-sim.

Update playlists in markdown

Get a Google API key and store it in the GOOGLE_API_KEY environment variables (turn on data from the app).

How to create sprite packs

Packs of images can be added to the editor using PXT packages. To create a package of images.

  1. Create a package (see steps above)
  2. Prepare your sprites in a spritesheet: All sprites in a sheet must be the same size and arranged in a grid with no gaps. Spritesheets must be PNG files. An example spritesheet is located here
  3. Inside the package directory, create a subdirectory where the assets will be placed and copy the spritesheet containing your images into it.
  4. Create a file named meta.json in the directory you created. An example meta.json can be found here and documentation on all of the options can be found here
  5. Create another .json file with the same basename as the spritesheet.
  6. Inside that file add a single property called frames which maps to an array of names for the sprites. Indices start in the top left of the sheet and proceed left to right. For a sample file see here
  7. From the root of your package, run the command pxt buildsprites SUBDIR where SUBDIR is the name of the directory containing the assets.
  8. Two files will be generated in the package root, one with the extenstion .ts and one with the extension .jres. Add both to the package's pxt.json
  9. You're done! The images will show up in the Image category when the package is added to a project

Local Dev setup

These instructions allow you to test changes to pxt-core and pxt-common-packages. They are more involved as you need to clone and link 3 repos.

  • install Node.js 8+ (you might need to restart afterwards so all your environment variables are applied correctly)
  • (optional) install Visual Studio Code

Automated setup

  • Download setup.cmd to your local machine and place it on the folder you'd like to do your development work
  • Run the following command
setup.cmd /firsttime

This call should automatically do the steps outlined in the manual setup and will clone and link all three repos.

Manual setup

  • install the pxt command line tool
[sudo] npm install -g pxt

In a common folder,

npm install
npm run build
  • go to pxt-common-packages and run
npm install
npm link ../pxt
  • go to pxt-arcade and run
npm install
npm link ../pxt
npm link ../pxt-common-packages

to run the local server

From root github folder,

cd pxt-arcade
pxt serve --rebundle

More instructions at https://github.com/microsoft/pxt#running-a-target-from-localhost

to watch for changes

To rebuild automatically when changes are made, we need gulp.

Install gulp:

npm install -g gulp

and in a seperate terminal from pxt serve and in the pxt/ folder, run:

gulp watch

Using setup.cmd

Instead of having to go to each repo, pull and link each one individually you may now use the setup.cmd file. The usage is outlined as follows with these options:
/firsttime Sets up developer environment - will clone 3 repos (pxt, pxt-arcade, and pxt-common-packages) and then run /link option
/pull Does a git pull on 3 repos (pxt, pxt-arcade, and pxt-common-packages)
/link Runs npm install and links the 3 repos
/run Runs local server and watches for changes using gulp

Viewing documents

Documents are rendered at the server and are viewable when received by the browser. Special styles and extended formatting are used which prevent them from rendering properly as generalized Markdown. While you can browse them here in the repo, they are not meant to render properly as GitHub document.
