I see there is a function called getBiomeArray but I don't know how to use it to loop through all the biomes of the chunk. Thanks!

See Chunk::getBiome for how to use this array.

Is it efficient to loop through the biome ids byte array to see if it matches a certain biome id? Can other mods ever change the default vanilla biome ids?

It's the best you can do.

 

Not other mods, but do not hardcode any IDs. If you must use them (like here), obtain them fresh from the registry.

Should I do this to get the integer ID of a biome?

 

Biome.REGISTRY.getIDForObject(Biomes.OCEAN);
