So I picked up this mod called Music Choices, which not only lets you play a lot more music than what comes with the vanilla game, but also lets you configure when it's played. Thing is, some of the choices require knowing what the entity IDs are. This isn't quite such a problem with the vanilla entities, but I've got a few mods that add creatures to the game.
I tried using TellMe to dump a list of entities, but I'm not at all convinced that it's accurate. For one thing, all the entity IDs are capitalized whereas the online lists of vanilla Minecraft entities are lowercase.
I've tried searching online for a solution, but all I've found is stuff about numerical IDs or how to register entities when making a mod.
I'm using 1.7.10 Minecraft, too, which probably isn't helping. But most of the mods I like haven't updated since this version, so I'm kinda stuck.
