With the number of biome adding mods continuing to increase it's getting much more difficult for mods that add biome specific world generation, or mobs to account for all the new biomes. While some biome mods have APIs that allow other modders to take advantage of their biomes, this solution has obvious drawbacks. Some mods classify biomes based on their properties, and work with them in this way (Forestry being an example). Although this works, most modders it seems would rather stick to vanilla biomes than put in the extra time required to do this. This has made biome mods less appealing to many players, as the difficulty of finding certain resources can sometimes make certain mods almost unplayable.

 

What I propose is to add a tag system to biomes so it could easily be specified that a given biome is forested, mountainous, etc. I've written such a system, mainly as an API for one of my own mods (A Sufficient Number of Biomes), which has worked relatively well so far. Having similar functionality in Forge, seems to me a way to solve this problem. My own code can be found here, which perhaps will serve as a better example of what I'm proposing. Naturally, if it is decided that such a feature would benefit Forge, you're free to recycle any of my code to implement it.

nice, please sumbit a pr
