And that could be helpful for me -- perhaps I don't have to use meta-data in my configs if users can get all the correct state labels.

Well, this is how I did it in order to print them out: /** * This will list all mobs, using there unlocalized names, writing * the data to the file lists/mobs.txt. */ public static void listMobs() { Set<ResourceLocation> mobrl = EntityList.getEntityNameList(); ArrayList<String> mobs = new ArrayList<String>(); for(ResourceLocation mob : mobrl) { mobs.add(mob.toString()); } Collections.sort(mobs); BufferedWriter outstream = null; File moblist = new File(listsDir.toString() + File.separator + "entities.txt"); if(moblist.exists()) moblist.delete(); try { outstream = new BufferedWriter(new FileWriter(moblist.toString())); for(String mob : mobs){ outstream.write(mob.toString()); outstream.newLine(); } if(outstream != null) outstream.close(); } catch (IOException e) { e.printStackTrace(); } } /** * This will list all items, using their complete unlocalized names * with mod id's, and write them the file lists/items.txt. This * is useful for writing theme files. */ public static void listItems() { BufferedWriter outstream = null; File itemlist = new File(listsDir.toString() + File.separator + "items.txt"); if(itemlist.exists()) itemlist.delete(); try { outstream = new BufferedWriter(new FileWriter(itemlist.toString())); for(Object item : Item.REGISTRY){ String name = Item.REGISTRY.getNameForObject((Item) item).toString(); if(true) { outstream.write(name); outstream.newLine(); } } if(outstream != null) outstream.close(); } catch (IOException e) { System.err.println("[DLDUNGEONS] Error: Could not write file items.txt"); e.printStackTrace(); } } /** * This will list all blocks using their correct, unlocalized names, complete with * mod id's, and write them to the file lists/blocks.txt. This is useful for editing * theme files. */ public static void listBlocks() { BufferedWriter outstream = null; File itemlist = new File(listsDir.toString() + File.separator + "blocks.txt"); if(itemlist.exists()) itemlist.delete(); try { outstream = new BufferedWriter(new FileWriter(itemlist.toString())); for(Object block : Block.REGISTRY){ String name = Block.REGISTRY.getNameForObject((Block)block).toString(); if(true) {; outstream.write(name); outstream.newLine(); } } if(outstream != null) outstream.close(); } catch (IOException e) { System.err.println("[DLDUNGEONS] Error: Could not write file blocks.txt"); e.printStackTrace(); } } I hope it helps.

Yeah for support on here, you need to be on one of the latest 2-3 versions or so, 1.7.10 is ancient and there have been a lot of changes/improvements since then. Your problem is (probably) best described in this error in your log: Caused by: java.lang.RuntimeException: Attempted to load class net/minecraft/client/resources/IResourcePack for invalid side SERVER You're trying to do client stuff on a server. The forge docs have an explanation of sides. http://mcforge.readthedocs.io/en/latest/concepts/sides/ This is important, regardless of the version of minecraft you are using. So, update to a newer (I'd go latest to be honest) version of forge, and if you need further help people here are pretty smart.

Recipes and entities are managed by registries, so register them in RegistryEvent.Register<IRecipe> and RegistryEvent.Register<EntityEntry> respectively. Use EntityEntryBuilder to create the EntityEntry. World Generators aren't managed by a registry and there's no dedicated event to register them, so do it in preInit/init/postInit.

So you got rid of the global id registration? Regarding the spawn egg, in 1.7.10 you need to create a custom egg (actual class for egg is called monster placer). See my tutorial link below on how to do that. I have an open source mod for 1.7.10 with multiple mobs. Feel free to adapt it to your needs here: https://github.com/jabelar/WildAnimalsPlus-1.7.10. I also have tutorials on custom entities here: http://jabelarminecraft.blogspot.com/p/creating-custom-entities.html

Okay, the stack overflow error is a bit weird at that line of code. I looked through your code and one thing that stands out is that you're double-registering your entities. You shouldn't use the global id registration. At the time of 1.7.10 they were transitioning from the global registration to per-mod id, but you should only use the mod id one. Furthermore, you don't need to set it based on the getGlobalUniqueID(0 method, but rather simply start at 0 for your mod and increment for each one. For example, in my mods I had something like this: protected int modEntityID = -1; public void registerModEntity(Class parEntityClass, String parEntityName) { EntityRegistry.registerModEntity(parEntityClass, parEntityName, ++modEntityID, WildAnimals.instance, 80, 3, false); } You'll note that I use a pre-increment ++ on the id so that if this gets called multiple times it will get the next id for next entity registered. I'm not sure but potentially the double-registering of your entities could cause some problem during rendering so maybe clean that up and see if it helps.
