platformer
Build a 2D platformer: run/jump control with coyote time, jump buffering, and variable jump height, plus tiled levels and hazards. Use for a platformer or Mario/Celeste-like, or tuning jump feel.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Platformer A playbook for 2D platformers — the run/jump controller "feel", level structure, hazards, and goals. This is a **compositional** skill: it wires an engine movement skill, a tilemap skill, and design skills into a working game. It does **not** re-teach physics or tilemaps; it tells you what to build and how to make jumping feel good. ## When to use - Use when building a side-scrolling or single-screen platformer, a "Mario-like" / "Celeste-like", or any game whose core verb is **jump between surfaces**. - Use when a jump feels floaty, unresponsive, or "unfair" and you need feel fixes (coyote time, jump buffering, variable height, corner correction). **When *not* to use:** top-down movement with no gravity → use the engine movement skill directly. 3D first-person traversal → `fps-shooter`. Grid/turn movement → `roguelike`. For the raw kinematic body API, use `godot-2d-movement` (or your engine's controller skill). ## Core loop **Observe a gap/hazard → commit to a jump or move → land safely (or die) → reach the next checkpoint/goal.** A platformer lives or dies on the *moment-to-moment* feel of that single jump, repeated thousands of times. Tighten the controller first; ev
- When to use
- Core loop
- Must-have systems
- Design knobs (make the jump feel right)
- Patterns
- 1. Solve jump physics from height + time (not magic numbers)
- 2. Coyote time + jump buffer + variable height (the feel core)
- 3. One-way platforms
- Pitfalls / failure modes
- Composition (build it from these skills)

What does the platformer skill do?
Build a 2D platformer: run/jump control with coyote time, jump buffering, and variable jump height, plus tiled levels and hazards. Use for a platformer or Mario/Celeste-like, or tuning jump feel.
How do I install it?
Run `npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill platformer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From gamedev-skills/awesome-gamedev-agent-skills, a repository with 406 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
