Spawn map

The spawn map allows you to control where creatures spawn in the world. You can enable or disable spawns for different areas using specific colors.

Spawn map File

Setting

Path to a spawn map file to use.

Requirements

See Image Requirements for the size and format requirements.
24 bit RGB PNG of medium resolution would be a sensible format for a spawn map.

Configuration

Spawn maps work together with a text file (spawnmap.txt) that defines what each color means.

Color behavior:

• Black color (#000000) is hardcoded to be no change - uses default spawn behavior
• White color (#FFFFFF) is hardcoded to disable all spawns in that area
• Other colors can be configured in spawnmap.txt to specify which creatures should spawn

Spawn Map Text File

The spawnmap.txt file defines what happens for each color in your spawn map. Each line follows this format:

RRGGBB: creature1, creature2, -creature3, all, none

Special keywords:

• all - enables all spawns
• none - disables all spawns
• -CreatureName - disables a specific creature (note the minus sign)

Rules:

• Enabling spawns sets the biome requirement to any biome, affecting the whole 64m x 64m zone
• Disabling spawns uses a more precise “clear area” system
• Commands are processed in order, so you can combine all with specific disables

Examples

# Red color enables Wolves and Skeletons to spawn in that area
FF0000: Wolf, Skeleton

# Blue color disables all spawns but enables Wolves and Skeletons
0000FF: none, Wolf, Skeleton

# Green color enables all spawns but disables Wolves and Skeletons
00FF00: all, -Wolf, -Skeleton

# Yellow color enables all creatures except Trolls
FFFF00: all, -Troll

# Purple color only allows Greydwarfs
800080: none, Greydwarf

Creation Tips

• Use high contrast colors that are easy to distinguish
• Test your spawn map in-game to ensure creatures spawn as expected
• Remember that spawn changes affect 64m x 64m zones, not individual pixels
• Use the minus prefix (-) to disable specific creatures when using all
