Wuppy29: Wuppy's Minecraft Forge Modding Tutorials for 1.6.2: Dimensions Part 2: ChunkProvider

Wuppy's Minecraft Forge Modding Tutorials for 1.6.2: Dimensions Part 2: ChunkProvider

In this tutorial series I will show you how to add a dimension to Minecraft. At first this will be the most basic possible dimension, but after that there will be some customization. In this tutorial I will show you how to add a basic ChunkProvider to the dimension. In the last tutorial we ended up with this code.

package tutorial;

import net.minecraft.world.WorldProvider;

import net.minecraft.world.biome.BiomeGenBase;

import net.minecraft.world.biome.WorldChunkManagerHell;

import net.minecraft.world.chunk.IChunkProvider;

public class WorldProviderTutorial extends WorldProvider

{

public void registerWorldChunkManager()

{

this.worldChunkMgr = new WorldChunkManagerHell(BiomeGenBase.desertHills, 0.8F, 0.1F);

this.dimensionId = Tutorial.dimensionId;

}

public IChunkProvider createChunkGenerator()

{

return new ChunkProviderTutorial(worldObj, worldObj.getSeed(), true);

}

@Override

public String getDimensionName()

{

return "Tutorial";

}

}

Right now you will have an error under ChunkProviderTutorial, because we haven't created that file just yet. Let's do this right now by hovering your mouse over it and clicking create class. When you do this you will get a file that looks like this.

package tutorial;

import java.util.List;

import net.minecraft.entity.EnumCreatureType;

import net.minecraft.util.IProgressUpdate;

import net.minecraft.world.ChunkPosition;

import net.minecraft.world.World;

import net.minecraft.world.chunk.Chunk;

import net.minecraft.world.chunk.IChunkProvider;

public class ChunkProviderTutorial implements IChunkProvider

{

@Override

public boolean chunkExists(int i, int j)

{

// TODO Auto-generated method stub

return false;

}

@Override

public Chunk provideChunk(int i, int j)

{

// TODO Auto-generated method stub

return null;

}

@Override

public Chunk loadChunk(int i, int j)

{

// TODO Auto-generated method stub

return null;

}

@Override

public void populate(IChunkProvider ichunkprovider, int i, int j)

{

// TODO Auto-generated method stub

}

@Override

public boolean saveChunks(boolean flag, IProgressUpdate iprogressupdate)

{

// TODO Auto-generated method stub

return false;

}

@Override

public boolean unloadQueuedChunks()

{

// TODO Auto-generated method stub

return false;

}

@Override

public boolean canSave()

{

// TODO Auto-generated method stub

return false;

}

@Override

public String makeString()

{

// TODO Auto-generated method stub

return null;

}

@Override

public List getPossibleCreatures(EnumCreatureType enumcreaturetype, int i, int j, int k)

{

// TODO Auto-generated method stub

return null;

}

@Override

public ChunkPosition findClosestStructure(World world, String s, int i, int j, int k)

{

// TODO Auto-generated method stub

return null;

}

@Override

public int getLoadedChunkCount()

{

// TODO Auto-generated method stub

return 0;

}

@Override

public void recreateStructures(int i, int j)

{

// TODO Auto-generated method stub

}

@Override

public void func_104112_b()

{

// TODO Auto-generated method stub

}

}

You could go and fill in all of these methods, but that would take weeks. The easiest thing to do is just copy over the code from ChunkProviderGenerate and edit that later. When you copy over the code there are a few things you have to do. First of all go to the top where there will be an error under the package line. Fix this by hovering over it and clicking "change package declaration to 'your package name'". Then go to the public class line and fix the error under ChunkProviderGenerate by clicking "rename type to 'your file name'". Finally use Ctrl, Shift, O to import all the required files and all the errors should be gone.
The file should now look something like this.

From now on I will never put the whole ChunkProvider file in these posts, because it is way too big. Instead I will show you the changed pieces of code.
I won't be explaining all of this code, because that would not really help a lot of people and it would take weeks to do so. However, in the customization tutorials I will show you what you may want to change in this file. In short the ChunkProvider pretty much generates or calls to generate all of the blocks. In here you can find code for caves, ravines, stone, biome blocks, dungeons, lakes etc. etc. It also does several other things like make the Ender eye work and the spawning of mobs.
These are all the files you need to create a proper dimension. However, you have no way to get there yet. In the next tutorials I will show you how to create a portal block and portal structure to get into the new dimension. After that will be loads of customization.

You can download the source code and the assets folder over here.

When you are done you can go back to the tutorial list over here.
