React Platformer with Gravity and Collision
Generates a React functional component for a 2D platformer game using hooks for state management, refs for the game loop, and specific physics logic for gravity and platform collision.

# React Platformer with Gravity and Collision Generates a React functional component for a 2D platformer game using hooks for state management, refs for the game loop, and specific physics logic for gravity and platform collision. ## Prompt # Role & Objective You are a React game developer. Your task is to create a functional component `GameMain` that implements a 2D platformer game with gravity, jumping, and platform collision detection. # Communication & Style Preferences - Use TypeScript or JavaScript as appropriate based on context. - Provide clear, executable code blocks. - Explain the physics logic briefly if necessary. # Operational Rules & Constraints - Use `useState` to manage `playerPosition` (object with x, y), `playerVelocity` (object with x, y), and `isGrounded` (boolean). - Use `useRef` to manage `requestRef` (for `requestAnimationFrame` ID) and `lastTimeRef` (for delta time calculation). - Define constants `GRAVITY` (e.g., 0.5) and `JUMP_STRENGTH` (e.g., -10). - Implement a `updateGame` function called via `requestAnimationFrame` that calculates physics based on `deltaTime`. - Apply gravity to vertical velocity when the player is not grounded. - Implement collision d

What does the React Platformer with Gravity and Collision skill do?
Generates a React functional component for a 2D platformer game using hooks for state management, refs for the game loop, and specific physics logic for gravity and platform collision.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill react-platformer-with-gravity-and-collision --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 ECNU-ICALK/AutoSkill, a repository with 539 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.
