Help: Making a dimension using forge, I need a in-depth tutorial.

I looked. I would love one on there too....

But I don't really know how to do it in the first place :P

I will add a tutorial on how to use METADATA blocks to have many blocks under one ID while still using Forge's Infinite Sprites.

Meh, no real point anymore honestly, unless you are dynamically creating things like RP2's microblocks, we have 4096 IDs now.  And if we are lucky then 1.3 or 1.4 will drop metadata (wishful thinking anyway).

Haha that friend would be me.

The Dimensions API is horribly outdated as the last Forge it worked with was 1.4...

However it's coded for Minecraft 1.2.5 so that would make it easier to make it work with the latest Forge :)

I'm also trying to create an new Dimension, but every time I try to click on my Teleporter Block it says "Entering Dimension" and when it's done loading I get this Error:

I think it's a problem with the worldProvider, so here is the Code:

package net.minecraft.src;

public class WorldProviderLEO extends WorldProvider{

@Override
public String getSaveFolder() {
	return "DIM-LEO";
}

@Override
public String getWelcomeMessage() {
	return "Entering LEO";
}

@Override
public String getDepartMessage() {
	return "Leaving LEO";
}

public boolean canRespawnHere(){
	return true;
}

public IChunkProvider getChunkProvider()
    {
        return new ChunkProviderLEO();
    }

}

 

And just to be sure the Code of my other classes:

 

 

mod_dim:

package net.minecraft.src;

import net.minecraft.src.forge.DimensionManager;

public class mod_dim extends BaseMod{

public static final Block BlockPortal = new BlockLeoPort(160, Material.portal);


public static final WorldProvider wpLEO = new WorldProviderLEO();


@Override
public void load() {
	ModLoader.registerBlock(BlockPortal);
	BlockPortal.blockIndexInTexture = ModLoader.addOverride("/terrain.png", "/portal.png");
	ModLoader.addName(BlockPortal, "Portal");
	ModLoader.addRecipe(new ItemStack(BlockPortal, 1), new Object [] {"#", Character.valueOf('#'), Block.dirt});

	DimensionManager.registerDimension(10, wpLEO, true);

}

public void onBlockClicked(World par1World, int par2, int par3, int par4, EntityPlayer par5EntityPlayer) {
	Minecraft mc = ModLoader.getMinecraftInstance();
	TeleporterLEO tl = new TeleporterLEO();

	mc.usePortal(10, tl);

	System.out.println("click");

}

public void onBlockClicked(World par1World, int par2, int par3, int par4, Entity par5Entity) {
	Minecraft mc = ModLoader.getMinecraftInstance();
	TeleporterLEO tl = new TeleporterLEO();

	mc.usePortal(10, tl);

	System.out.println("click");

	par5Entity.setFire(1);
}

Edit:

 

I think the WorldProvider was not what causes the Problem.Now I think it was the ChunkProvider. I've changed a few thinks and now I get this Error:

The ChunkProvider now looks like this:

        //BiomeGenBase var5 = this.worldObj.getBiomeGenForCoords(par2, par4);
        //return var5 == null ? null : var5.getSpawnableList(par1EnumCreatureType);
    	return null;
    }


    public ChunkPosition findClosestStructure(World par1World, String par2Str, int par3, int par4, int par5)
    {
        return null;
    }

}

 

When I reenter the save I spawn in some Blocks, so I die after a few seconds. When I respawn I spawn so high over the ground, that I die by the falldamage.

I think the Problem now is the Teleporter, but I can't find what causes the Problem, so could someone please help me? For the Teleporter´s Code look in the Spoiler above.
