BiomeAtlas

A Forge mod for 1.7.10 that generates a map of biomes via command or on startup.

• Supports mod-added biomes.
• Great for finding that perfect seed.

Compiling

./gradlew clean build

Usage

/biomeatlas <apothem> [<resolution>]

Apothem is the "radius" of a square around you in chunks (not blocks). Each chunk is a 16x16 area of blocks.

Resolution is an optional parameter that lets you generate larger areas in shorter amounts of time by skipping 1 in X chunks. Specifically, it is the number of distinct chunks represented per pixel in one dimension. The default value is 1, which means that each chunk gets its own pixel in the map. A value of 2 will halve the size of the map and so on. Higher values allow you to map larger areas without increasing the amount of time it takes to generate the map.

Generate on Start

Or instead, you can have map generation be initiated when a server is started with:

-DbiomeAtlas.mapOnStartup=true

Such as:

java -Xmx5G -DbiomeAtlas.mapOnStartup=true -jar forge.jar

You can also define the following properties:

-DbiomeAtlas.apothem=250
-DbiomeAtlas.mapDimension=0
-DbiomeAtlas.centerX=0
-DbiomeAtlas.centerZ=0
-DbiomeAtlas.resolution=1
-DbiomeAtlas.exitOnFinish=false

Finding a Seed

To find an ideal seed, you can make a Batch script or a shell script to continually restart a server with a new seed and have BiomeAtlas generate a map each time.

Linux:

for i in `seq 1 50`;
do
	rm -Rf world
	java -Xmx5G -DbiomeAtlas.mapOnStartup=true -DbiomeAtlas.exitOnFinish=true -jar forge.jar nogui
done

Windows:

@echo off
for /l %%x in (1, 1, 50) do (
   rmdir /s /q world
   java -Xmx5G -DbiomeAtlas.mapOnStartup=true -DbiomeAtlas.exitOnFinish=true -jar forge.jar nogui
)
pause

You should find a bunch of biomeatlas_.png files in the same directory.
