🏰 Binary Space Partitioning Dungeon Generator | Unity 2022 Implementation

📜 Technical Overview

This system implements a ​Binary Space Partitioning (BSP) algorithm to generate procedural 2D dungeons in Unity 2022. The solution features recursive space division and intelligent connection strategies to create highly playable dungeon layouts.

🔍 Core Algorithm Workflow

1️⃣ Initial Space Partitioning

• 🧩 Initializes from a rectangular bounding box

• ✂️ Recursively divides space using binary splitting

• 🎲 Randomly selects split axis (horizontal/vertical) and position

• ⏹️ Termination condition: subspace reaches preset room size threshold

  

2️⃣ Leaf Node Identification

• 🌳 Constructs complete binary tree data structure

• 🔢 Assigns unique identifiers to each leaf node

• 🚪 Leaf nodes correspond to final room units

  

3️⃣ Spatial Relationship Construction

• 🏗️ Maintains complete tree topology

• 📐 Records spatial boundary information for each node

• 🔗 Establishes parent-child and sibling connections

  

4️⃣ Corridor Generation Algorithm

• 🛣️ Implements bottom-up traversal strategy

• 🤝 Creates shortest path connections between adjacent spaces

• 📏 Dynamically adjusts corridor width parameters

  

5️⃣ Wall System

• 🧱 8-direction neighborhood detection

• 🔢 Bitmask-based wall calculation

• 📐 Automatic wall texture angle matching
