Allow custom world types to generate up to a height of 255

[Two]

As the title says: I'd love to be able to allow custom world types to be able to generate worlds with a height of 256. The changes necessary are actually very simple and I tried them already by modifying vanilla code. The following (hand written) patch would modify the code so that both vanilla generation and 256 generation would be possible.

 

Chunk.java:131

- int var9 = par2ArrayOfByte[var6 << 11 | var7 << 7 | var8] & 0xFF;

+ int var9 = var5 == 256? par2ArrayOfByte[var6 << 12 | var7 << 8 | var8] & 0xFF : par2ArrayOfByte[var6 << 11 | var7 << 7 | var8] & 0xFF;

 

MapGenCaves.java:20

+ final int chunkDataHeight = par5ArrayOfByte.length / 256;

 

:137

- var45 = (var42 * 16 + var43) * 128 + var44;

+ var45 = (var42 * 16 + var43) * chunkDataHeight + var44;

 

:139

- if (var44 >= 0 && var44 < 128)

+ if (var44 >= 0 && var44 < chunkDataHeight)

 

:165

- int var48 = (var42 * 16 + var45) * 128 + var38;

+ int var48 = (var42 * 16 + var45) * chunkDataHeight + var38;

 

MapGenRavine.java:11

+ final int chunkDataHeight = par5ArrayOfByte.length / 256;

 

:124

- var44 = (var41 * 16 + var42) * 128 + var43;

+ var44 = (var41 * 16 + var42) * chunkDataHeight + var43;

 

:126

- if (var43 >= 0 && var43 < 128)

+ if (var43 >= 0 && var43 < chunkDataHeight)

 

:152

- int var47 = (var41 * 16 + var44) * 128 + var37;

+ int var47 = (var41 * 16 + var44) * chunkDataHeight + var37;

Max build-height of the world is currently 256, but you can only generate the world with a max height of 128.
