Dungeonizer - Procedural Dungeon Generator

Generate playable tile-based dungeons in seconds.

Dungeonizer is a lightweight procedural dungeon generator for Unity, designed for developers who want fast results without learning a huge framework. Use it to create modular 2D or 3D RPG dungeons, roguelike levels, maze-like layouts, cave-style rooms, prototype maps, and runtime-generated environments.

Dungeonizer focuses on one thing: simple, customizable dungeon generation that you can understand, modify, and use in real projects.

Whether you are a beginner who wants a generator that works out of the box, or a programmer who wants a hackable base algorithm, Dungeonizer gives you a practical foundation for procedural level creation.

Why Dungeonizer?

Many dungeon generators are powerful but complex. Dungeonizer is built for developers who want something faster, simpler, and easier to customize.

You can generate dungeons directly in the editor, or create them at runtime while the game is running. Use the included sample assets, or plug in your own wall, floor, corner, door, enemy, chest, decoration, player, and exit prefabs.

Dungeonizer is especially useful for:

• RPG dungeons
• Roguelike and roguelite levels
• Dungeon crawler prototypes
• Procedural room-and-corridor layouts
• Low-budget indie games
• Runtime-generated levels
• Fast level design experiments

Current Features

• Editor generation: Generate dungeons inside the Unity Editor for fast level creation and testing.
• Runtime generation: Generate dungeons on the fly during gameplay.
• 2D and 3D support: Build tile-based dungeon layouts for both 2D and 3D projects.
• Custom wall and floor prefabs: Replace the included samples with your own modular dungeon pieces.
• Custom room support: Add handcrafted rooms to specific areas of your dungeon for more controlled level design.
• Adjustable tile size: Match the generator to your own grid scale and prefab dimensions.
• Adjustable corridor size: Create narrow tunnels, wider paths, or larger connecting areas.
• Customizable room count and room sizes: Control how many rooms are generated and how large they can be.
• High-speed generation: Designed to stay fast even with very large dungeon layouts.
• Start prefab support: Automatically place your player, spawn point, or custom start object.
• Exit point generation: Add an exit, goal, portal, stairs, or next-level trigger to the generated dungeon.
• Automatic dungeon population: Place enemies, chests, decorations, doors, goals, pickups, or any custom prefab type.
• Door support: Automatically generate door locations for dungeon rooms and corridors.
• Custom corner prefabs: Add corner pieces that rotate automatically to match the generated layout.
• Sample assets included: Includes sample tileset assets to help you get started quickly.

Custom Prefab Population

Dungeonizer can automatically populate your generated dungeons with your own prefabs.

Examples:

• enemies
• chests
• decorations
• traps
• doors
• goal objects
• collectibles
• keys
• portals
• NPCs
• boss room objects

This makes Dungeonizer more than a layout generator. It can help you create playable dungeon spaces with content already placed inside.

Custom Rooms

Dungeonizer now supports custom rooms, giving you more control over your procedural levels.

Use custom rooms for:

• boss rooms
• treasure rooms
• puzzle rooms
• spawn rooms
• story rooms
• shops
• special encounters
• handcrafted set pieces

This lets you combine procedural generation with intentional level design.

Included Sample Assets

Dungeonizer includes sample assets so you can test the generator immediately.

You can use the included tileset with Dungeonizer projects, or replace it with your own modular dungeon prefabs.

Built for Simplicity

Dungeonizer is designed for low-budget indie games and developers who want a generator that is easy to understand.

The goal is not to hide everything behind a massive framework. The goal is to give you a clean procedural dungeon system that works, can be customized, and can be extended when your project needs more.

Simple to use.

Easy to modify.

Fast to generate.

Flexible enough for real game prototypes.
