Schematic Based World Generator

Well guys I have an issue, somebody has tasked me with the goal of creating a world generator that takes a 4*4 chunk (exactly sized) schematic and tile it all over the world.

The issue is I have never done world generation and have no idea how to do this. The only progress I have made so far is creating the actual schematic and using:

Code:

CuboidClipBoard schematic = SchematicFormat.MCEDIT.load(new File(Plugin.instance.getDataFolder(), "Plots.schematic"));

To load it.

Help would really be appreciated.

    }
 
    @Override
    public byte[][] generateBlockSections(World world, Random random, int cx, int cz, BiomeGrid biomes) {
        byte[][] result = new byte[world.getMaxHeight() / 16][];
        //

                //
                int zBlock = (zRegion * 16) + z;
                //
                for (int y = 0; y < world.getMaxHeight(); y++) {
                    try {
                        BaseBlock block = schematic.getPoint(new BlockVector(xBlock, y, zBlock));
                        setBlock(result, x, y, z, (byte) block.getType());
                    } catch (ArrayIndexOutOfBoundsException ex) {
                        //
                    }
                }
            }
        }
        return result;
    }
 
    private void setBlock(byte[][] result, int x, int y, int z, byte blkid) {
        if (result[y >> 4] == null) {
            result[y >> 4] = new byte[4096];
        }
        result[y >> 4][((y & 0xF) << 8) | (z << 4) | x] = blkid;
    }
}
 

The above seems to generate part of the plots, ie 2/4 chunks are correct, I think.

as looking to the ode you posted, it generate schunks at an area of 2X2 chunks, but at the forum thread, you said 4X4, what is correct?

 

Odd, my checkerboard test works just fine.

Sorry meant 2*2

 

you are ignoring a IndexOutOfBound exception, mostly, these indicate bugs, can you verify if its correct?

 

Sorry I derped, I do mean 4*4. Wonder how to fix..

    private void setBlock(byte[][] result, int x, int y, int z, byte blkid) {
        if (result[y >> 4] == null) {
            result[y >> 4] = new byte[4096];
        }
        result[y >> 4][((y & 0xF) << 8) | (z << 4) | x] = blkid;
    }
}
 

Done, I just do xPos = cx % 4;
