Best practices for GameMaker Language (GML) development, covering scripts, object events, rooms, data structures, and performance-minded game code. Use when writing GML scripts or object event code in GameMaker Studio, structuring create/step/draw events, managing rooms and instances, building state machines for gameplay, or optimizing GML for performance.
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
# GameMaker Language (GML) Development This skill covers writing maintainable, performant game code in GameMaker Language (GML), including code organization, style conventions, gameplay architecture, and performance patterns specific to GameMaker Studio. ## Workflow for Building GML Gameplay Features 1. **Design the object** — Decide what Create, Step, Draw, Collision, and Alarm events the object needs, and what data it owns. 2. **Initialize in Create** — Set default variable values, instantiate data structures (`ds_map`, `ds_list`, structs), and cache references (layer IDs, other instance IDs) in the Create event. 3. **Simulate in Step** — Put input handling, physics/movement, state machine transitions, and collision response in Step (or Step-adjacent events like Begin/End Step). 4. **Render in Draw** — Keep Draw events limited to rendering; never mutate gameplay state there. 5. **Extract reusable logic into scripts** — Move any behavior used by more than one object, or any event body that's grown complex, into a named script/function. …

How to install
mdr add mindrally/skills/gamemaker-gml@sha256:c00e6867f19a8517The line at the top of this page pins the label git:20261008.7682ca7, 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.
