How do I generate/ungenerate things in my biome

[leonardude]

Hey all!

 

I was wondering how do I generate/ungenerate things in my biome. More specifically, I'm looking to disable stone if possible (I know you need your own ChunkProvider to do that but I don't know how to get that to work, it's okay if I can't disable stone), disable the generation of anything (besides stone if it isn't possible to turn off stone generation) vanilla minecraft, including ores, flowers, cacti, trees, etc.. Also, I would want to enable my own flowers, enable my own cactus, enable my own tees etc.

 

This is the code for my biome:

 

package com.leonardude.zether.biomes;

 

import com.leonardude.zether.main.Zether;

 

import net.minecraft.world.biome.BiomeGenBase;

 

public class BiomeGenCorruptDesert extends BiomeGenBase {

 

public BiomeGenCorruptDesert(int id) {

super(id);

 

//Biome Settings

this.setMinMaxHeight(-1.0F, 1.0F);

this.setDisableRain();

this.setTemperatureRainfall(2.0F, 0.0F);

 

//Customize Biome

this.topBlock = (byte) Zether.corrosiveSand.blockID;

this.fillerBlock = (byte) Zether.zetherStone.blockID;

 

//Disable Blocks

 

//Disable Mobs

this.spawnableCaveCreatureList.clear();

this.spawnableCreatureList.clear();

this.spawnableMonsterList.clear();

this.spawnableWaterCreatureList.clear();

 

//Enable Mobs

 

}

 

}

 

PS this biome will be in a custom dimension

 

Thanks in advance!

In the chunk provider make the change in two of the methods:

 

In generate terrain:

public void generateTerrain(int par1, int par2, byte[] par3ArrayOfByte) {
	byte b0 = 4;
	byte b1 = 16;
	byte b2 = 63;
	int k = b0 + 1;
	byte b3 = 17;
	int l = b0 + 1;
	this.biomesForGeneration = this.worldObj.getWorldChunkManager().getBiomesForGeneration(this.biomesForGeneration, par1 * 4 - 2, par2 * 4 - 2, k + 5, l + 5);
	this.noiseArray = this.initializeNoiseField(this.noiseArray, par1 * b0, 0, par2 * b0, k, b3, l);

	for (int i1 = 0; i1 < b0; ++i1) {
		for (int j1 = 0; j1 < b0; ++j1) {
			for (int k1 = 0; k1 < b1; ++k1) {
				double d0 = 0.125D;
				double d1 = this.noiseArray[((i1 + 0) * l + j1 + 0) * b3 + k1 + 0];
				double d2 = this.noiseArray[((i1 + 0) * l + j1 + 1) * b3 + k1 + 0];
				double d3 = this.noiseArray[((i1 + 1) * l + j1 + 0) * b3 + k1 + 0];
				double d4 = this.noiseArray[((i1 + 1) * l + j1 + 1) * b3 + k1 + 0];
				double d5 = (this.noiseArray[((i1 + 0) * l + j1 + 0) * b3 + k1 + 1] - d1) * d0;
				double d6 = (this.noiseArray[((i1 + 0) * l + j1 + 1) * b3 + k1 + 1] - d2) * d0;
				double d7 = (this.noiseArray[((i1 + 1) * l + j1 + 0) * b3 + k1 + 1] - d3) * d0;
				double d8 = (this.noiseArray[((i1 + 1) * l + j1 + 1) * b3 + k1 + 1] - d4) * d0;

				for (int l1 = 0; l1 < 8; ++l1) {
					double d9 = 0.25D;
					double d10 = d1;
					double d11 = d2;
					double d12 = (d3 - d1) * d9;
					double d13 = (d4 - d2) * d9;

					for (int i2 = 0; i2 < 4; ++i2) {
						int j2 = i2 + i1 * 4 << 11 | 0 + j1 * 4 << 7 | k1 * 8 + l1;
						short short1 = 128;
						j2 -= short1;
						double d14 = 0.25D;
						double d15 = (d11 - d10) * d14;
						double d16 = d10 - d15;

						//requires change in both methods to properly generate custom dimension blocks under biomes
						for (int k2 = 0; k2 < 4; ++k2) {
							if ((d16 += d15) > 0.0D) {
								par3ArrayOfByte[j2 += short1] = (byte) Block.glowStone.blockID;//Block.stone.blockID;
							} else if (k1 * 8 + l1 < b2) {
								par3ArrayOfByte[j2 += short1] = (byte) Fluids.blockRasterWasser.blockID;
							} else {
								par3ArrayOfByte[j2 += short1] = 0;
							}
						}

						d10 += d12;
						d11 += d13;
					}

					d1 += d5;
					d2 += d6;
					d3 += d7;
					d4 += d8;
				}
			}
		}
	}
}

 

And replace block:

public void replaceBlocksForBiome(int par1, int par2, byte[] par3ArrayOfByte, BiomeGenBase[] par4ArrayOfBiomeGenBase) {
	ChunkProviderEvent.ReplaceBiomeBlocks event = new ChunkProviderEvent.ReplaceBiomeBlocks(this, par1, par2, par3ArrayOfByte, par4ArrayOfBiomeGenBase);
	MinecraftForge.EVENT_BUS.post(event);
	if (event.getResult() == Result.DENY)
		return;

	byte b0 = 63;
	double d0 = 0.03125D;
	this.stoneNoise = this.noiseGen4.generateNoiseOctaves(this.stoneNoise, par1 * 16, par2 * 16, 0, 16, 16, 1, d0 * 2.0D, d0 * 2.0D, d0 * 2.0D);

	for (int k = 0; k < 16; ++k) {
		for (int l = 0; l < 16; ++l) {
			BiomeGenBase biomegenbase = par4ArrayOfBiomeGenBase[l + k * 16];
			float f = biomegenbase.getFloatTemperature();
			int i1 = (int) (this.stoneNoise[k + l * 16] / 3.0D + 3.0D + this.rand.nextDouble() * 0.25D);
			int j1 = -1;
			byte b1 = biomegenbase.topBlock;
			byte b2 = biomegenbase.fillerBlock;

			for (int k1 = 127; k1 >= 0; --k1) {
				int l1 = (l * 16 + k) * 128 + k1;

				if (k1 <= 0 + this.rand.nextInt(5)) {
					par3ArrayOfByte[l1] = (byte) Block.bedrock.blockID;
				} else {
					byte b3 = par3ArrayOfByte[l1];

					if (b3 == 0) {
						j1 = -1;
					} else if (b3 == Block.glowStone.blockID) {
						if (j1 == -1) {
							if (i1 <= 0) {
								b1 = 0;
								b2 = (byte) Block.dirt.blockID;//was dirt
							} else if (k1 >= b0 - 4 && k1 <= b0 + 1) {
								b1 = biomegenbase.topBlock;
								b2 = biomegenbase.fillerBlock;
							}

							if (k1 < b0 && b1 == 0) {
								if (f < 0.15F) {
									b1 = (byte) Block.ice.blockID;
								} else {
									b1 = (byte) Fluids.blockRasterWasser.blockID;
								}
							}

							j1 = i1;

							if (k1 >= b0 - 1) {
								par3ArrayOfByte[l1] = b1;
							} else {
								par3ArrayOfByte[l1] = b2;
							}
						} else if (j1 > 0) {
							--j1;
							par3ArrayOfByte[l1] = b2;

							if (j1 == 0 && b2 == Block.sand.blockID) {
								j1 = this.rand.nextInt(4);
								b2 = (byte) Block.sandStone.blockID;
							}
						}
					}
				}
			}
		}
	}
}

 

I made mine create glowstone while I was testing the dimension.

[leonardude]

So do I have to edit actual minecraft or do I create my own ChunkProvider? I'm thinking that I have to create my own ChunkProvider but I'm not sure.

[Danickar]

I have my own chunk provider.

[leonardude]

And then in my biomes I extend that chunk provider right?

And what does the code that you posted do?

[leonardude]

Can someone reply?

[Danickar]

Biomes do not extend the ChunkProvider.

[leonardude]

So then how do I use my ChunkProvider that I create?

[leonardude]

So then how do I use my ChunkProvider that I create?

[leonardude]

What do I do with my ChunkProvider after I create it? Which classes extend it if any?
