terraforge-core 1.3.1

A customizable Python tool for generating maps for games and simulations.

TerraForge v1.3.1 🗺️

Procedural Biome/Island & Dungeon Map Generator using Simplex Noise

TerraForge is a versatile Python toolset for procedural map generation.

It includes tools for creating noise-based biome maps and multi-level dungeon layouts with fine-grained control over terrain shaping, biome placement, and dungeon structure.

🚀 Features

🌍 Biome Generator (TerraForge)

• Elevation, Moisture, and Temperature map generation
• Supports single and clustered multi-island generation
• Falloff support: Radial, Edge, or None
• Parameters for island spread, spacing, scale, and strength
• Basic biome color mapping based on environmental conditions
• Outputs high-resolution PNG images
• JSON preset import/export for reuse in games

🏰 Dungeon Generator (DungeonForge)

• Multi-level dungeon generation (3D stack of floors)
• Procedural room placement and corridor carving
• Up/down stairs for vertical navigation
• Console-based movement demo included
• Optional PNG export per dungeon level
• Tile color customization for export
• JSON preset import/export

📦 Requirements

• noise
• numpy
• pillow

📦 Installation

You can install TerraForge using pip.

pip install terraforge-core

🧪 Demos

Biome Map Generator

Run the included demo script:

python demo.py

The generated maps will be saved as biome_map, elevation_map, moisture_map, temperature_map, (noise_type)_map.

Dungeon Map Generator

Run either the included dungeon_demo script or dungeon_demo1 script.

python dungeon_demo.py

Console based demo with movement.

python dungeon_demo1.py

Generates .pngs for each dungeon level.

🚀 Usage - TerraForge (Biome Maps)

from terraforge import TerraForge

generator = TerraForge(map_size=300, image_size=(600, 600))

generator.generate(output_dir="maps")

🔁 Preset Workflow

generator.export_preset("world_preset.json")

generator.import_preset("world_preset.json")
generator.generate("maps")

🧩 Biome Schema (Presets)

Biomes are stored as a list of objects. Each biome requires:

• color (hex string)
• rules (dict of noise_type -> [min, max])

Optional (recommended for tools like TerraForge Studio):

• id (unique string per biome)
• name (display name)

Example biome:

{
  "id": "forest",
  "name": "Forest",
  "color": "#3E7C3C",
  "rules": {
    "elevation": [0.4, 0.6],
    "moisture": [0.5, 1.0]
  }
}

Notes:

• id is optional, but if provided it must be unique within the preset.
• Rule ranges must satisfy min <= max.

🚀 Usage - DungeonForge (Dungeons)

from dungeonforge import DungeonForge

generator = DungeonForge()

dungeon_map = generator.generate()

🔁 Preset Workflow

generator.export_preset("dungeon_preset.json")

generator.import_preset("dungeon_preset.json")
generator.generate()

⚙️ Customization Options

Biome Generator

Edit the values in terraforge.py or the demo to control:

• map_size and image_size

• falloff type: "radial", "edge", or None

• num_islands, island_spread, min_island_spacing

• noise types (elevation, moisture, temperature)

• biome_thresholds for noise types (elevation, moisture, and temperature)

Dungeon Generator

• Map size (width, height)
• Number of levels (z_levels)
• Maximum rooms and room size constraints
• Tile symbols and export colors
• Specify which levels to export (levels=[0, 2])
