In this tutorial you will learn how to install Unity CLI and how to use it to build a complete 2D Procedural Dungeon generator using a FREE Unity 6 starter project.
๐ฆ FREE starter project:
patreon.com/sunnyvalleystudio/posts/free-project-2d-166653562

Unity CLI documentation:

Prompts:
drive.google.com/file/d/12UCZqRLfu9x50AXx6fgK3npSEooDf3Xj/view?usp=drive_link
Assets used:
o-lobster.itch.io/simple-dungeon-crawler-16x16-pixel-pack
---------------------------------------------------
โ๏ธ WHAT YOU WILL LEARN:
Installing, authenticating and configuring the Unity CLI
- Installing the com.unity.pipeline package so the CLI can drive a running Editor
- Connecting an AI agent (Claude Code, or Codex / ChatGPT) directly to your open project
- How procedural dungeon generation actually works โ random placement with rejection, and Prim's algorithm for connecting rooms with corridors
- Deriving walls, colliders and decorations from a single set of floor cells
- Spawning enemies, props and traps without anything overlapping
- Prompting and iteration strategies for AI-assisted Unity work โ including catching the things the AI gets wrong
