I've implemented this, but I am still getting errors when trying to add my custom biome

I can't find any method named get in ResourceKey

It's what it said to do here. Again it was the only resource I had on this.

My FMLCommonSetupEvent is being fired, I've debugged the method call but nothing seems out of the ordinary.

I've been trying to implement a custom biome and I've run across an error that crashes my game when trying to create a new world and disallows me to enter any existing worlds. I followed this tutorial for making biomes (with one or two changes to class names and method names). My code looks like this and the exception is this What exactly am I missing? I understand that the tutorial is for 1.16, but I couldn't find anything for 1.17 and so far it hasn't been that difficult to implement it into my project. Did they add a step in 1.17?

I figured it out, thanks. It turns out I had to use event.getGeneration().addStructureStart() instead of event.getGeneration().getStructures().add() among a few other things like updating my version of forge.

The post you linked is for 1.16, I doubt the code would work for 1.17

The code which utilizes BiomeLoadingEvent I have already shown above but here it is again: This code for the feature is this: And the code for the structure piece is this: I mainly took advantage of the many examples in vanilla to make the above two classes

My mod is for minecraft 1.17.1, forge 37.0.67. Should I move my project to 37.0.95? I utilize BiomeLoadingEvent at line 68 in my code, but that alone did not add structures to the game. I also had to use reflection to add my own StructureFeatureConfiguration.

A long time ago I tried to make a Minecraft mod (key word is tried). I knew a lot less about Java back then and I mainly relied on the tutorial videos I found. Recently I decided to try and get back into it, and I found it was really fun! I've started doing things that I had no chance of figuring out how to do last time like implementing custom mobs and even bosses. The biggest problem is that there are close to no tutorials or any actual useful documentation for forge 1.17.1, but because of my increased skill level since my last modding attempt, I haven't had to rely on tutorials that much I recently started trying to add custom entity spawning to the game, but couldn't figure out how to do it in the current forge version. Eventually I just decided to use reflection to add my own data into the vanilla map of "spawners" in net.minecraft.world.level.biome.MobSpawnSettings. This obviously isn't the intended way to add custom entity spawning to the game but because I can't find anything on this subject online, I did it and it works. Entity spawning isn't the main subject of this post, but it gives you the backstory of what I'm about to do (or more specifically, what I did). After that, I wanted to add my own custom structure. I decided to add an RV that spawns in deserts and mesa biomes so I just looked at how vanilla adds structures. I created all the proper java classes for the structure itself (The Feature class and the Pieces class) and created a StructureFeature field and a ConfiguredStructureFeature from that Feature. Then in a similar fashion to what I did with the entities, In biomes I wanted my structure to spawn in, I added my ConfiguredStructureFeature to "structureStarts" in net.minecraft.world.level.biome.BiomeGenerationSettings using reflection. On top of that I also added my own StructureFeatureConfiguration to "BUILTIN_OVERWORLD" from net.minecraft.world.level.levelgen.NoiseGeneratorSettings. If you're wondering, it works... kind of When I create a new world, It will spawn the structures but after I exit that world it will take a long time to load the world and there are many EOFExceptions in the console. I did the best job I could do with debugging and found that the error was happening while loading the NBT data for structures in every chunk. It is having a lot of trouble when trying to do something having to do with structure references. I have done my best to try and see exactly what is going wrong in the code and how I can fix it, but frankly, I'm stumped and I have no idea of how to fix it. Honestly the way to fix it is probably to stop using reflection and to just properly register my structures, but I don't know how to do that. After I've exhausted every single solution I can think of, I finally decided to come here and ask for help. My code for world generation:

Yes but how do I make all nearby entities start panicking

I'm making a mob like zombified piglin except instead of all the mobs getting mad at you I want to make it do they all go into a panic. How can I do this?

I fixed it by making a liquidblock for the fluid, which I didn't do (correctly). Additionaly, I made the class extend FlowingFluid instead of ForgeFlowingFluid.
