[1.8] Cannot find my custom biome!

Arionas_MC · July 18, 2017

Hello guys! I am currently coding a mod with a lot of new biomes, but I cannot find them! I register every biome like this:

@EventHandler
public void preInit(FMLPreInitializationEvent event) {
    
    BiomeDictionary.registerBiomeType(exampleForest, Type.FOREST);
    BiomeManager.addSpawnBiome(exampleForest);
    	
}

Do I register them correctly?

(I am using MinecraftForge 1.8-11.14.2.1427)

That brings back memories...

I used BiomeManager.addBiome() in 1.8

I THINK that addSpawnBiome only means that it is possible that the world spawn is inside the specified Biome.

Is there any way to see if my biome has been spawned?

You could try to use this: https://takahikokawasaki.github.io/minecraft-resources/javadoc/forge/1.8-11.14.1.1320/net/minecraftforge/event/terraingen/package-summary.html

Or just use BiomeProvider findBiomePosition. silly me

I cannot find any 'BiomeProvider' class...

Jacky2611 · July 18, 2017

Ähm, give me a moment. I am digging through my old code. Could you try to look inside the WorldChunkManager?

Jacky2611 · July 18, 2017

It might be WorldChunkManager.a(int i, int j, int k, List<Biome> list, Random random)

BiomeProvider might be a renamed WorldChunkManager in 1.9.

Hey, whenever I register my biome with BiomeManager.addBiome, the Minecraft world doesn't start!

Jacky2611 · July 18, 2017

log? And hey, crashes are definitely better than nothing.

And show us your current code.

When I start a new world with that line of code it prints this:

Good news your Biome is generating. Bad news you are generating to many trees.

30 possible trees per chunk is a little to much.

In your decorate method print out the BlockPos argument to find the position.

What do you mean? If you do System.out.println(pos) it will print out the BlockPos and you will have coordinates for where your Biome is being decorated.

Jacky2611 · July 18, 2017

It will print the position whenever your biome get decorated.

However, that would require your biome to be generated first. I would instead somehow (e.g. on item right click) run WorldChunkManager.a(int i, int j, int k, List<Biome> list, Random random) and print the result. If this really is the findBiome function it should work even if your biome hasn't been generated yet. Just make sure that the range is big enough.

Well after 5 minutes of exploring the world, it printed the position but Minecraft stopped responding!

Post your Biome code again.

Jacky2611 · July 18, 2017

Your biome might still be taking up too many resources. How much power does your device have and how much are you generating?

Can you give us a github link?

How big are your trees? If they are near vanilla size you shouldn't be generating much more than 3-4 per chunk, also there is Runaway Chunk Generation. Which is a huge problem in world gen. If your generation passes over into another chunk then that chunk will be forced to generate and so on and so forth if it is your Biome it will call your decorate method and lead to more chunks being loaded.

Edit: You will want to apply an offset to your generation so it doesn't load other chunks.
