Use this skill FIRST for any melonJS task; it routes to the right specialised skill and lists the companion packages. melonJS is an open-source 2D, 2.5D and 3D HTML5 game engine running on WebGPU, WebGL 2 or Canvas. Covers Application setup, the scene graph, renderables, sprites, tilemaps, physics, audio, particles, shaders, and the 3D tier — perspective cameras, meshes and glTF scenes. Triggers on: melonjs, melonJS, me.game, Application, app.init, app.world, Renderable, Sprite, Stage…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# melonJS Entry point for the melonJS skill collection. melonJS is an open-source HTML5 game engine for indie developers, covering 2D, 2.5D and 3D — perspective and orthogonal cameras, GPU-accelerated tilemap rendering, post-processing effects, custom shaders, 3D meshes, polygon-accurate physics and modern Tiled workflows. It runs on WebGPU, WebGL 2 or Canvas with automatic fallback, and has no runtime dependencies. ## How to use this skill 1. Find the specialised skill below that matches the task and follow it. 2. If the task involves anything 3D, read `melonjs-3d` **first** — melonJS's coordinate conventions are the inverse of OpenGL's, so untutored 3D instincts are backwards. 3. If you are writing melonJS from prior knowledge rather than from the current docs, read `melonjs-20-migration` — most published melonJS material predates 20.0 and its bootstrap no longer exists. 4. If none of them covers the task, use the escape hatch below rather than guessing at an API. ## Skill router | Skill | Load when… | |---|---| …

How to install
mdr add melonjs/melonjs/melonjs@sha256:455e32a652c420b3The line at the top of this page pins the label git:20261102.0ab2067, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
