[1.7.10] Issue with a furnace like block

The_SlayerMC · August 16, 2014

Ive made an incubator, but when you put the recipe inside the gui, it doesnt smelt and when you exit the gui the items inside it are gone! The block doesnt update like it should (go from idle to active)

So can someone please help?

Block registry:

public static final Block incubatorIdle = new BlockIncubator("incubatorIdle", false);
public static final Block incubatorActive = new BlockIncubator("incubatorActive", true);

The block:

public class BlockIncubator extends BlockContainer {

protected boolean active;
protected static boolean keepInventory;
protected Random rand = new Random();

public BlockIncubator(String name, boolean act) {
	super(Material.rock);
	setStepSound(Block.soundTypeStone);
	if(!act) setCreativeTab(EssenceTabs.blocks);
	setBlockName(name);
	GameRegistry.registerBlock(this, name);
	active = act;
	if(act) setLightLevel(0.875F);
}

*Bump*

I don't know what you have wrong, because the code I can see seems fine.

It kind of seems like your client and server containers are not both active. What code opens your Incubator gui? Please show that.

The_SlayerMC · August 17, 2014

public class GuiHandler implements IGuiHandler {

private static int guiID = 0;
public static int stats = guiID++, enrichmentTable = guiID++, incubator = guiID++;

@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	if(ID == stats) return new ContainerEmpty();
	if(ID == enrichmentTable) return new ContainerEnrichedTable(player.inventory, world, x, y, z, player);
	if(ID == incubator) return new ContainerIncubator(player.inventory, new TileEntityIncubator());
	return null;
}

@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
	if(ID == stats) return new GuiStats();
	if(ID == enrichmentTable) return new GuiEnrichedEnchantmentTable(player.inventory, world, x, y, z, player);
	if(ID == incubator) return new GuiIncubator(player.inventory, new TileEntityIncubator());
	return null;
}
}

Don't return a new instance of the tile entity! You should be sending the instance retrieved from the world: TileEntity te = world.getTileEntity(x, y, z), and check if it's an instanceof your TE class before casting it and passing it to the Container's constructor.

Oh wow.... I can't believe that I missed that... HAHAHA woops
