[1.7.2] Refrain River Biome From Generating

Posted July 10, 201411 yr

Is there anyway to stop the river biome from generating in my custom world type? I have my own GenLayerBiome class, but it's still generating the river.

WorldType:

package terrarium.world;

import net.minecraft.world.World;
import net.minecraft.world.WorldType;
import net.minecraft.world.biome.WorldChunkManager;
import net.minecraft.world.gen.layer.GenLayer;
import net.minecraft.world.gen.layer.GenLayerIsland;

public class WorldTypeT extends WorldType {
public int size;

public WorldTypeT(int size) {
	super("SIZE" + size);
	this.size = size;
}

@Override
public WorldChunkManager getChunkManager(World world) {
	return new WorldChunkManagerT(world.getSeed(), this);
}

@Override
public GenLayer getBiomeLayer(long worldSeed, GenLayer parentLayer) {
	return new GenLayerBiomeT(200L, parentLayer, this);
}
}

GenLayerBiome:

package terrarium.world;

import net.minecraft.world.WorldType;
import net.minecraft.world.biome.BiomeGenBase;
import net.minecraft.world.gen.layer.GenLayer;
import net.minecraft.world.gen.layer.GenLayerBiome;
import net.minecraft.world.gen.layer.GenLayerIsland;
import net.minecraft.world.gen.layer.GenLayerSmooth;
import net.minecraft.world.gen.layer.GenLayerVoronoiZoom;
import net.minecraft.world.gen.layer.IntCache;
import terrarium.ServerProxy;
import terrarium.util.MathUtil;

public class GenLayerBiomeT extends GenLayerBiome {
public int size;

public GenLayerBiomeT(long seed, GenLayer layer, WorldTypeT worldType) {
	super(seed, layer, worldType);
	this.size = worldType.size;
}

@Override
public int[] getInts(int chunkX, int chunkZ, int par3, int par4) {
	int[] current = IntCache.getIntCache(par3 * par4);

	int realX;
	int realZ;
	double distance;

	for(int z = 0; z < par4; z++) {
		for(int x = 0; x < par3; x++) {
			realX = x + chunkX;
			realZ = z + chunkZ;

			this.initChunkSeed((long) realX, (long) realZ);

			distance = MathUtil.getDistance2D(0, 0, realX, realZ);

			if(distance > 24 * size) {
				current[x + z * par3] = BiomeGenBase.deepOcean.biomeID;
			} else if(distance > 12 * size) {
				current[x + z * par3] = BiomeGenBase.ocean.biomeID;
			} else if(distance > 9 * size) {
				current[x + z * par3] = BiomeGenBase.taigaHills.biomeID;
			} else if(distance > 6 * size) {
				current[x + z * par3] = BiomeGenBase.desert.biomeID;
			} else if(distance > 3 * size) {
				current[x + z * par3] = BiomeGenBase.forest.biomeID;
			} else {
				current[x + z * par3] = ServerProxy.forest.biomeID;
			}
		}
	}

	return current;
}
}

WorldChunkManager:

[code}

package terrarium.world;

import java.lang.reflect.Field;

import net.minecraft.world.WorldType;

import net.minecraft.world.biome.WorldChunkManager;

import net.minecraft.world.gen.layer.GenLayer;

import terrarium.util.LogUtil;

public class WorldChunkManagerT extends WorldChunkManager {

public WorldChunkManagerT(long seed, WorldType worldType) {

super(seed, worldType);

}

[/code]

I think you star out with the base GenLayer, and then you pass it on to other GenLayers to modify?

I tried it earlier, and the 2 GenLayer fields in WorldChunkManager are private.

I already have my own chunk manager, it's just that the fields are private. Should I override the methods that use those fields and use my own gen layer?

Ok, I got the private field problem out of the way, thanks to reflection <3

Current problem is that the world is just a big ocean ATM. I have my own GenLayer in my world type, but it doesn't seem to affect the world.

WorldChunkManager:

package terrarium.world;

import java.lang.reflect.Field;

import net.minecraft.world.WorldType;
import net.minecraft.world.biome.WorldChunkManager;
import net.minecraft.world.gen.layer.GenLayerIsland;
import terrarium.util.LogUtil;

public class WorldChunkManagerT extends WorldChunkManager {
public WorldChunkManagerT(long seed, WorldType worldType) {
	super(seed, worldType);

	replaceField("genBiomes", new GenLayerIsland(1000L));
	replaceField("biomeIndexLayer", new GenLayerIsland(1000L));
}

private void replaceField(String fieldName, Object value) {
	Field field = null;

	try {
		field = this.getClass().getSuperclass().getDeclaredField(fieldName);
	} catch(NoSuchFieldException e) {
		e.printStackTrace();
	} catch(SecurityException e) {
		e.printStackTrace();
	}

	if(field != null) {
		LogUtil.info(fieldName + " field found, replacing");

		field.setAccessible(true);

		try {
			field.set(this, new GenLayerIsland(1000L));
		} catch(IllegalArgumentException e) {
			e.printStackTrace();
		} catch(IllegalAccessException e) {
			e.printStackTrace();
		}
	}
}
}

I have no clue what I'm doing any more :'(

Every is an ocean biome, except for the block at 0, 0, which is a plains biome.

WorldChunkManager:

package terrarium.world;

import java.lang.reflect.Field;

import net.minecraft.world.biome.WorldChunkManager;
import net.minecraft.world.gen.layer.GenLayer;
import net.minecraft.world.gen.layer.GenLayerIsland;
import terrarium.util.LogUtil;

public class WorldChunkManagerT extends WorldChunkManager {
public WorldChunkManagerT(long seed, WorldTypeT worldType) {
	super(seed, worldType);

	GenLayer genLayer = GenLayerBiomeT.init(seed, worldType);

	replaceField("genBiomes", genLayer);
	replaceField("biomeIndexLayer", genLayer);
}

private void replaceField(String fieldName, Object value) {
	Field field = null;

	try {
		field = this.getClass().getSuperclass().getDeclaredField(fieldName);
	} catch(NoSuchFieldException e) {
		e.printStackTrace();
	} catch(SecurityException e) {
		e.printStackTrace();
	}

	if(field != null) {
		LogUtil.info(fieldName + " field found, replacing");

		field.setAccessible(true);

		try {
			field.set(this, new GenLayerIsland(1000L));
		} catch(IllegalArgumentException e) {
			e.printStackTrace();
		} catch(IllegalAccessException e) {
			e.printStackTrace();
		}
	}
}
}

GenLayerBiomeT:

package terrarium.world;

import net.minecraft.world.biome.BiomeGenBase;
import net.minecraft.world.gen.layer.GenLayer;

public int size;

public GenLayerBiomeT(long seed, WorldTypeT worldType) {
	super(seed, null, worldType);
	this.size = worldType.size;
}

@Override
public int[] getInts(int chunkX, int chunkZ, int par3, int par4) {
	int[] current = IntCache.getIntCache(par3 * par4);

	int realX;
	int realZ;
	double distance;

	for(int z = 0; z < par4; z++) {
		for(int x = 0; x < par3; x++) {
			realX = x + chunkX;
			realZ = z + chunkZ;

			this.initChunkSeed((long) realX, (long) realZ);

			distance = MathUtil.getDistance2D(0, 0, realX, realZ);

			if(distance > 24 * size) {
				current[x + z * par3] = BiomeGenBase.deepOcean.biomeID;
			} else if(distance > 12 * size) {
				current[x + z * par3] = BiomeGenBase.ocean.biomeID;
			} else if(distance > 9 * size) {
				current[x + z * par3] = BiomeGenBase.taigaHills.biomeID;
			} else if(distance > 6 * size) {
				current[x + z * par3] = BiomeGenBase.desert.biomeID;
			} else if(distance > 3 * size) {
				current[x + z * par3] = BiomeGenBase.forest.biomeID;
			} else {
				current[x + z * par3] = ServerProxy.forest.biomeID;
			}
		}
	}

	return current;
}

public static GenLayer init(long seed, WorldTypeT worldType) {
	GenLayer genLayerT = new GenLayerBiomeT(1L, worldType);
	GenLayer genLayerFuzzyZoom1 = new GenLayerFuzzyZoom(2000L, genLayerT);
	GenLayer genLayerFuzzyZoom2 = new GenLayerFuzzyZoom(2001L, genLayerFuzzyZoom1);
	GenLayer genLayerFuzzyZoom3 = new GenLayerFuzzyZoom(2002L, genLayerFuzzyZoom2);
	GenLayer genLayerMagnify = GenLayerZoom.magnify(1000L, genLayerFuzzyZoom3, 0);
	GenLayer genLayerSmooth1 = new GenLayerSmooth(1000L, genLayerMagnify);
	GenLayer genLayerVoronoiZoom = new GenLayerVoronoiZoom(10L, genLayerSmooth1);
	GenLayer genLayerSmooth2 = new GenLayerSmooth(1000L, genLayerVoronoiZoom);

	return genLayerSmooth2;
}
}

Sorry for necro, but this is one of the first search results for this issue. Possible cause is Forge checking for zlib (the expected hash) and not accepting zlib-ng (the actual hash):

https://github.com/PrismLauncher/ForgeWrapper/issues/3

One possible workaround (aside from swapping zlib-ng for zlib which might cause other problems on your system) would be to use the prism flatpak.

Bad pathfinding for big mobs (1.21.1)

Well I was mainly trying to figure out whether or not I was doing something wrong and if it could be fixed by just adding something (e.g. maybe I was missing an Attribute or something like that), but if that's not the case then my only option is to use custom pathfinding. If someone has one that functions and is willing to share it, then I'd gladly use that instead of suffering through making my own.
