Tiles

A JumPHP engine extension (docs/extensions.md of JumPHP): a Composer package of type jumphp-extension. A game that requires it gets its services, its boot class, its file loaders and its project.yaml keys, with nothing to wire.

public function __construct(private Flash $flash) {}        // in a scene
$this->flash->flash('#ff4040');                            // then update($dt) / render($r) each frame

Example game: games/tiles-demo.

Install (for the games that use it)

bin/jumphp extension:add <game> <vendor>/<package>      # composer require + checks it is a jumphp-extension

Make it yours

• composer.json: rename name (<your-vendor>/<package>), fill description, license, homepage, support; keep "type": "jumphp-extension" and the keyword jumphp-extension (jumphp.net/extensions lists the Packagist packages that have it).
• extra.jumphp.engine: the JumPHP versions it works with ("^0.5", ">=0.5 <0.7"): a game on another version stops at boot with a clear message instead of failing somewhere inside. Widen it once you tried the newer JumPHP.
• Do not require jumphp/engine in require (every JumPHP project has it already); pure PHP only (the browser build packs it).
• doc/index.md: its documentation, and doc/samples/*.php: one scene for each thing it does (namespace App\Extensions\<Name>, a public const LABEL). bin/jumphp extension:add <game> <package> copies them into the game (extensions/<name>/doc/, src/Extensions/<Name>/), and the JumPHP IDE opens the documentation with a Play button per sample.
• Tests: the example game's tests/ play the extension (bin/jumphp test <id>-demo). Write one per feature.

Publish it

1. A public GitHub repository with this folder's content at its root (composer.json at the top).
2. A tag: git tag v1.0.0 && git push --tags (Packagist's versions are the tags; follow semver).
3. https://packagist.org/packages/submit with the repository's address (sign in with GitHub, Packagist then installs its hook: each new tag is a new version).
4. It appears in https://jumphp.net/extensions by itself (it reads the Packagist packages of type jumphp-extension).
5. Show it: a README with a picture, the example game's screenshot (bin/jumphp shot), a CHANGELOG.
