[1.7.10]How to make an ore spawn in a specific biome

[MrFloatingCow]

How do i make a specific ore spawn in a specific biome,like an emerald, and if you can, please send me an example code.

Look at class ChunkProviderGenerate, especially its replaceBlocksForBiome method. I see a Forge event hook in there that could be useful if you subscribe to it.

Once you've chosen a position to generate your ore at, you can use

World#getBiomeGenForCoords

to check the biome at that position. If it's the right biome, generate your ore; otherwise do nothing.
