Multi Block Structures

[insane_gravy]

I'm attempting to create a new furnace built like the coke oven furnace in Railcraft. However, I have no idea how to approach this. Thus far, I have the following files present.

 

package insanegravy.herbcraft.common;

import net.minecraft.src.EntityPlayer;
import net.minecraft.src.FurnaceRecipes;
import net.minecraft.src.IInventory;
import net.minecraft.src.ItemStack;
import net.minecraft.src.TileEntity;
import net.minecraft.src.World;
import net.minecraftforge.common.ForgeDirection;
import net.minecraftforge.common.ISidedInventory;

public class TileOvenBrick extends TileEntity implements IMatrixEntity, IInventory, ISidedInventory {
private ItemStack[] furnaceItemStacks = new ItemStack[3];

public TileOvenBrick() {

}

@Override
public boolean isValidCombination() {
	TileOvenBrick[] x = (TileOvenBrick[]) getXBound();
	TileOvenBrick[] y = (TileOvenBrick[]) getYBound();
	TileOvenBrick[] z = (TileOvenBrick[]) getZBound();

	return (Math.abs(x[0].xCoord - x[1].xCoord) == 1) && (Math.abs(y[0].yCoord - y[1].yCoord) == 1) && (Math.abs(z[0].zCoord - z[1].zCoord) == 1);
}

public static TileOvenBrick getAbove(TileOvenBrick tile) {
	TileEntity above = tile.worldObj.getBlockTileEntity(tile.xCoord, tile.yCoord + 1, tile.zCoord);

	if (above instanceof TileOvenBrick) {
		return (TileOvenBrick) above;
	} else {
		return null;
	}
}

public static TileOvenBrick getBelow(TileOvenBrick tile) {
	TileEntity below = tile.worldObj.getBlockTileEntity(tile.xCoord, tile.yCoord - 1, tile.zCoord);

	if (below instanceof TileOvenBrick) {
		return (TileOvenBrick) below;
	} else {

	}
}

public static TileOvenBrick getNextX(TileOvenBrick tile) {
	TileEntity nextX = tile.worldObj.getBlockTileEntity(tile.xCoord + 1, tile.yCoord, tile.zCoord);

	if (nextX instanceof TileOvenBrick) {

	} else {

	}
}

		return (TileOvenBrick) prevX;
	} else {
		return null;
	}
}

public static TileOvenBrick getNextZ(TileOvenBrick tile) {
	TileEntity nextZ = tile.worldObj.getBlockTileEntity(tile.xCoord, tile.yCoord, tile.zCoord + 1);

	if (nextZ instanceof TileOvenBrick) {
		return (TileOvenBrick) nextZ;
	} else {
		return null;
	}
}

public static TileOvenBrick getPrevZ(TileOvenBrick tile) {
	TileEntity prevZ = tile.worldObj.getBlockTileEntity(tile.xCoord, tile.yCoord, tile.zCoord - 1);

	if (prevZ instanceof TileOvenBrick) {
		return (TileOvenBrick) prevZ;
	} else {

	}
}

@Override

	TileEntity[] result = new TileOvenBrick[2];
	TileOvenBrick nextX = this;

}

public int idDropped(int par1, Random par2Random, int par3) {
        return modHerbcraft.BlockOvenBrick.blockID;

Beyond this, I have no idea what I'm supposed to do. If the blocks are placed in the proper arrangement, how do I get them to behave as a single unit?

You can take a look in the Railcraft's Source code. That's the best way in learning programming in any language or API.

[insane_gravy]

Where can I find the source?

[opssemnik]

why you need the src?, just use onUpdate method or onPlacedBy

[insane_gravy]

Do those methods go in the TileEntity class or the Block class?
