## What it does

The file carries project context for a tower defense game driven by a Nintendo Ringcon, where players place turrets and charge them through exercise. The codebase is mid-refactor for extensibility and maintainability, and the rule keeps that in front of the assistant on every edit.

Inside are a few instructions: mechanics should feel intuitive and responsive, performance gets tuned for real-time gameplay, and code stays modular so new features do not break old ones. The project language is C#, Unity version 2021.3.18f1. Point this at a different Unity version or a different genre and some of the guidance will miss — it was written for one specific repository, not for Unity in general.

Install is a single file at `.cursor/rules/unity-cursor-ai-c-cursorrules-prompt-file.mdc`. The `**/*` glob with `alwaysApply: false` means it does not attach itself: you pull it in when you are working on gameplay.

## Requirements
- Works with: Unity

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/unity-cursor-ai-c-cursorrules-prompt-file.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/unity-cursor-ai-c-cursorrules-prompt-file.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/unity-cursor-ai-c-cursorrules-prompt-file.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/unity-cursor-ai-c-cursorrules-prompt-file.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/unity-cursor-ai-c-cursorrules-prompt-file.md`

## When to use it
- keep the assistant aware of a Unity project's context
- remind the model about modular structure during refactoring
- set a performance target for real-time gameplay
- pin the Unity version and language in AI prompts
- describe Nintendo Ringcon input so the model does not assume keyboard controls

## Example prompts
- read the unity-cursor-ai-c-cursorrules-prompt-file rule and suggest how to split this class into modules
- given the project context, how do I optimize turret updates for real-time gameplay
- check my C# code against the instructions in the Unity rule
