What is parity? This category is designed just for features that exist but work one way on one platform, and another way on a different platform. Bugs are not parity!

(Java Parity) /fillbiome command

The /fillbiome command really helps mapmakers and content creators in Bedrock because it’s the only way to change biomes in-game. 

Adding the /fillbiome command removes the need of third-party world editors to change biomes in the world on Bedrock.

Command syntax:

/fillbiome <from> <to> <biome> replace <filter>

The fillbiome command also has an optional alternate syntax when using the replace option.

    The limit volume of the source region is not controlled by commandModificationBlockLimitgamerule as the gamerule does not exist in Bedrock. Instead it uses a hardcoded value 32768.

    Example of the command:

    Because biomes in a world are stored in cells of 4×4×4 blocks, this command is applied on each selected cell instead of each block.

    Although biomes are stored in cells, biome boundaries are slightly fiddled with to make them smooth. So the shape of the region whose biome is actually changed is irregular.

    The command only changes the biome, but not the blocks in it. For example, changing a forest to a desert with this command does not change the grass blocks to sand and does not plant cacti, but rabbit spawn in the new "desert" that still looks like a forest.

    • This command is used to attempt to change the biome between the two stone blocks to desert.
       
    • As shown here, the biome changes are not applied at the exact coordinates specified.

    With that command, I turned a Plains Biome into a Swamp on Java. Wish I could use it on Bedrock.

    Java had Fillbiome for over a year already. I thought mojang was focused on adding parody...
