tile-level-generator

This project provides a level generator that can be controlled by a human user to generate tile-based levels as well as episode data that can be used to train an AI agent for procedural content generation (PCG) through apprenticeship learning.

Requirements

• Unity 2017.2.1f1

Working with the project

Open the project in Unity and load the scene Scenes/Editor. This is the primary scene used for human-controlled level creation.

The tile-based generator

This generator is used to create top down dungeon levels in the style of adventure games like The Legend of Zelda.

Tile-based levels are created by controlling a "digger" character. At the start of a level creation session, the digger is presented with a grid filled entirely with blocks. As the digger moves from tile to tile, they "dig out" each space that they move to, converting it into a traversable open space. Actions the digger can perform are:

• Movement up, down, left, and right to clear out paths
• Create small, medium, and large square rooms centered around the digger
• Place treasure, enemy, and level exit tiles
• Place keys and locked doors

Human controls

The following keys can be used for manual control of the digger:

• w, a, s, d or ↑, ←, ↓, →: movement
• 1: Create small room (3x3)
• 2: Create medium room (5x5)
• 3: Create large room (7x7)
• j: Place treasure
• k: Place enemy
• u: Place key
• i: Place locked door (Note: Keys must be placed before doors can be created to ensure playability)
• p: Place level exit
• Esc: Save and quit the current level generating session
  • Upon quitting, text will appear in a selectable console on the screen with the path to files containing the generated tilemap and the recorded episode data (a series of states and actions).
• Insert: Spawn an AI digger at the starting location which executes a concrete set of actions
• Delete: Destroys the AI digger
