Tile Entity Problems

[Bedrock_Miner]

Hey Guys!

I created a TileEntity which should work nearly the same as a furnace with the difference that it uses no fuel.

 

I have a problem with this furnace: If I place a stack in the slot to take the ingredients from, it starts taking them, but if I leave the Gui and reopen it, the process is back at zero. Why?

 

Code:

 

  Reveal hidden contents

Tile Entity:

package com.bedrockminer.magicum.block.tileentity;

import ...;

public class TileElementaryExtractor extends TileEntity implements IInventory{

public ItemStack[] inventory = new ItemStack[2];
private int refresh = 5;
private int process;

@Override
public int getSizeInventory() {
	return this.inventory.length;
}

@Override
public ItemStack getStackInSlot(int slot) {
	return (slot >= 0 && slot < this.inventory.length) ? this.inventory[slot] : null;
}

@Override
public ItemStack decrStackSize(int slot, int amt) {
	ItemStack stack = this.getStackInSlot(slot);
        if (stack != null) {
        	if (stack.stackSize <= amt) {
        		this.setInventorySlotContents(slot, null);
        	} else {
        		stack = stack.splitStack(amt);
        		if (stack.stackSize == 0) {
        			this.setInventorySlotContents(slot, null);
        		}
            }
        }
        return stack;
}

@Override
public ItemStack getStackInSlotOnClosing(int slot) {
	ItemStack stack = this.getStackInSlot(slot);
	if (stack != null) {
		this.setInventorySlotContents(slot, null);
	}
	return stack;
}

@Override
public void setInventorySlotContents(int slot, ItemStack stack) {
	if (slot < this.getSizeInventory())
        {
       	 	this.inventory[slot] = stack;
       	 	if (stack != null && stack.stackSize > this.getInventoryStackLimit()) {
       	 		stack.stackSize = this.getInventoryStackLimit();
       	 	}
        }
}

@Override
public String getInventoryName() {
	return "inventory.elementaryExtractor";
}

@Override
public boolean hasCustomInventoryName() {
	return false;
}

@Override
public int getInventoryStackLimit() {
	return 64;
}

@Override
public boolean isUseableByPlayer(EntityPlayer player) {
	return true;
}

@Override
public void openInventory() { }

@Override
public void closeInventory() { }

@Override
public boolean isItemValidForSlot(int slot, ItemStack stack) {
	return true;
}

public int getProgress() {
	return this.progress > 128 ? 128 : this.progress;
}

public void addProgress(int amount) {
	this.progress += amount;
}

public void checkProgress() { //Checks whether the process variable is full enough to add an item to the output
	while (this.progress > 128) {
		if (this.getStackInSlot(1) == null || (this.getStackInSlot(1).stackSize < this.getInventoryStackLimit() && this.getStackInSlot(1).getItem() == ItemElements.getEssenceForce(Elements.values()[this.element]))) {
			this.progress -= 128;
			if (this.getStackInSlot(1) == null) {
				this.setInventorySlotContents(1, new ItemStack(ItemElements.getEssenceForce(Elements.values()[this.element])));
			} else {
				this.getStackInSlot(1).stackSize ++;
			}
			this.markDirty();
		} else {
			break;
		}
	}
}

@Override
public void updateEntity() { //Takes one item from the input every fifth tick
	if (--this.refresh <= 0) {
		if (this.element != 0 && this.getStackInSlot(0) != null) {
			if (ItemElements.getElementsForStack(this.getStackInSlot(0)) != null && ItemElements.getElementsForStack(this.getStackInSlot(0)).contains(Elements.values()[this.element])) {
				this.addProgress(ItemElements.getValueForStack(this.getStackInSlot(0)));
				CommonUtils.reduceItemStack(this, 0, 1);
				this.markDirty();
			}
		}
		this.checkProgress();
		this.refresh  = 5;
	}
}

@Override
    public void readFromNBT(NBTTagCompound tagCompound) {
    	super.readFromNBT(tagCompound);
    	NBTTagList tagList = tagCompound.getTagList("Items", 10);
        this.inventory = new ItemStack[this.getSizeInventory()];

        for (int i = 0; i < tagList.tagCount(); ++i)
        {
            NBTTagCompound nbttagcompound1 = tagList.getCompoundTagAt(i);
            int j = nbttagcompound1.getByte("Slot") & 255;

            if (j >= 0 && j < this.inventory.length)
            {
                this.inventory[j] = ItemStack.loadItemStackFromNBT(nbttagcompound1);
            }
        }
        this.progress = tagCompound.getInteger("Progress");
    }

    @Override
    public void writeToNBT(NBTTagCompound tagCompound) {
    	super.writeToNBT(tagCompound);
    	NBTTagList tagList = new NBTTagList();

        for (int i = 0; i < this.inventory.length; ++i)
        {

            {
                NBTTagCompound nbttagcompound1 = new NBTTagCompound();
                nbttagcompound1.setByte("Slot", (byte)i);
                this.inventory[i].writeToNBT(nbttagcompound1);
                tagList.appendTag(nbttagcompound1);
            }
        }

        tagCompound.setTag("Items", tagList);
        tagCompound.setInteger("Progress", this.progress);
    }

@Override
public Packet getDescriptionPacket() {
	NBTTagCompound nbt = new NBTTagCompound();
	this.writeToNBT(nbt);
	return new S35PacketUpdateTileEntity(this.xCoord, this.yCoord, this.zCoord, this.getBlockMetadata(), nbt);
}

@Override
public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt) {
	this.xCoord = pkt.func_148856_c();
	this.yCoord = pkt.func_148855_d();
	this.zCoord = pkt.func_148854_e();
	this.blockMetadata = pkt.func_148853_f();
	this.readFromNBT(pkt.func_148857_g());
}
}

 

Container:

package com.bedrockminer.magicum.client.gui.container;

import ...;

public class ContainerElementaryExtractor extends Container {

public TileElementaryExtractor te;
public EntityPlayer thePlayer;

public ContainerElementaryExtractor (EntityPlayer player, TileElementaryExtractor te) {
	this.te = te;
	this.thePlayer = player;
	this.addSlotToContainer(new Slot(te, 0, 32, 56));
	this.addSlotToContainer(new SlotResult(player, te, 1, 130, 56));
	this.addPlayerInventory(player.inventory);

}

@Override
public boolean canInteractWith(EntityPlayer var1) {
	return true;
}

protected void addPlayerInventory(InventoryPlayer inventoryPlayer) {
    	for (int i = 0; i < 3; i++) {
    		for (int j = 0; j < 9; j++) {
    			this.addSlotToContainer(new Slot(inventoryPlayer, j + i * 9 + 9,  8 + j * 18, 98 + i * 18));
    		}
    	}
    	for (int i = 0; i < 9; i++) {
    		this.addSlotToContainer(new Slot(inventoryPlayer, i, 8 + i * 18, 156));
    	}
    }

}

 

Gui:

package com.bedrockminer.magicum.client.gui;

import ...;

public class GuiElementaryExtractor extends GuiContainer {

private ContainerElementaryExtractor container;

public GuiElementaryExtractor(ContainerElementaryExtractor container) {
	super(container);
	this.container = container;
	this.xSize = 176;
	this.ySize = 180;
}

@Override
protected void drawGuiContainerBackgroundLayer(float var1, int mouseX, int mouseY) {
	...
}

@Override
protected void drawGuiContainerForegroundLayer(int mouseX, int mouseY) {
	...

	//Render the Progress Bar
	this.drawTexturedModalRect(38, 80, 0, 20, 100, 5);
	this.drawTexturedModalRect(38, 80, 0, 25, this.container.te.getProgress() * 100 / 128, 5);
}

}

 

 

Actually, the block should smelt every tick because of the onUpdate method. Actually it resets everytime I open the gui.

I think you're not reading the TileEntity's inventory, when you open the container.

[Bedrock_Miner]

Do you have to read the inventory seperately? I thought this is automatically linked to the inv..

[Bedrock_Miner]

If no one has an idea, I'm going to delete the TE, copy the code from tileEntityFurnace and recreate everything.

[Abastro]

I think it is related with syncing container... you have to send the progress data to client.

[Bedrock_Miner]

I don't exactly understand what you mean. Which data should I sync and when?

[GotoLink]

The burning time needs to be sync on the client to be drawn into the GUI.

See ContainerFurnace.

[Bedrock_Miner]

I copied some code and now I think I found the problem..

I have a button in the Gui which controls the furnace. (Sorry, I havent posted this part of code)

The Furnace only works if this button is pressed (It's a toggle-button)

I thought, this would work, thats why I didn't post it. But: The value of the button is not synchronized with the server.

Do I need a packet to do this or is there another way?

There is an easy way to transfer button-clicks when viewing a GuiContainer.

When you want a send a button-click, call

Minecraft#playerController.sendEnchantPacket(windowId, buttonId)

. The windowId you get from your Container, the buttonId can be a byte (-128 through 127).

That will then trigger a call to

enchantItem

on your Container (on the server!) with the same buttonId.

The naming is a bit stupid (classic MCP...), I bet in the original Mojang code this is called clickButton or something like that.

 

Thanks a lot! It works now..

 

The deobfuscated names are a little bit weird sometimes, you're right....

I think, ICrafting would better be called ICraftingUser or something, because thats what it is used for....
