[1.7.10]Custom Furnace Issues

Recommended Posts

There are only two issues with my furnace right now that need to be fixed. Before I carry on I want to say that, before I ever post on this forum I take a lot of time reviewing my code, comparing it to vanilla, make sure things are matching up right, so on and so forth. The two issues are not very big and I think are most likely the issue is hidden behind one line of code.

 

Issue 1:

 

The activated furnace texture does not turn on.

 

Issue 2:

 

When using shift click and an item is in the a certain slot in the furnace, it will go into the output slot.

If anyone has made a furnace before in 1.7.10 and has all this stuff working, I would love to have some advice from you.

 

Thanks!

In getIcon, you should be checking if the metadata == side, instead you are checking if the metadata == 0 and the side == 3. This will only use the front furnace texture on side 3. I suggest you use something like this to check if the furnace is active:

@SideOnly(Side.CLIENT)
public IIcon getIcon(IBlockAccess world, int x, int y, int z, int side) {
// get wether the furnace is active, then return the propper texture
}

Code: [select]

@SideOnly(Side.CLIENT)

public IIcon getIcon(IBlockAccess world, int x, int y, int z, int side) {

// get wether the furnace is active, then return the propper texture

}

 

I think you are referring to two different methods of getIcon in that responce, but I'm pretty sure I know which is which.

 

I think your saying I need to do this? It does not show the front angle of the item though.

@SideOnly(Side.CLIENT)
public IIcon getIcon(int side, int metadata){
	//return metadata == 0 && side == 3 ? this.iconFront : (side == metadata ? this.iconFront : this.blockIcon);
	return side == metadata ? this.iconFront : this.blockIcon;
}

 

And for this method your saying something like this? Although I'm not positive what I should be returning in this getIcon method.

@SideOnly(Side.CLIENT)
public IIcon getIcon(IBlockAccess world, int x, int y, int z, int side){
	if(isActive){
		return //what do I put here
	}
}

 

Thanks

1. Use the IBlockAccess (in your case, it's named world) and use it to find the TileEntity of your furnce, use world.getTileEntity(x, y, z), make sure it is an instance of YourCustomFurnaceTileEntity, cast it to one, use a field/method to ask the tile entity wether or not it's active. By doing it this way instead of the Vanilla way, you don't need to have two blocks (active and inactive) but just one.

2. Return any IIcon that you register in registerIcons, you will need to check the side to see if you should return the side icon or the front active/idle icon.

This is the furnace that I made, feel free to use it as a refernece. Other than a minor graphical glitch, mine works perfectly.

I like the way you did your block, but I don't really want to re-code most of code unless I necessarily have to. I am using the updateFurnaceBlockState and you aren't. I want to be closer to the vanilla side of things, unless for some reason I have to change my code to be similar to yours.

 

I did make some progress though. At least I think.

In the method updateEntity() in the TileEntity class, when updating the blockFurnaceState there was a problem.

Here's the original updateEntity code:

public void updateEntity() {
	boolean flag = this.hasPower();
	boolean flag1= false;

	if(hasPower() && this.isInfusing()) {
		this.dualPower--;
	}

		if (this.hasItemPower(this.slots[2]) && this.dualPower <= (this.maxPower - this.getItemPower(this.slots[2]))) {
			this.dualPower += getItemPower(this.slots[2]);

			if(this.slots[2] != null) {
				flag1 = true;

				this.slots[2].stackSize--;

				if(this.slots[2].stackSize == 0) {
					this.slots[2] = this.slots[2].getItem().getContainerItem(this.slots[2]);
				}
			}
		}

		if (hasPower() && canInfuse()) {
			dualCookTime++;

			if (this.dualCookTime == this.infusingSpeed) {
				this.dualCookTime = 0;
				this.infuseItem();
				flag1 = true;
			}
		}else{
			dualCookTime = 0;
		}

		if (flag != this.isInfusing()) {
			flag1 = true;
			CrypticInfuser.updateFurnaceBlockState(this.isInfusing(), this.worldObj, this.xCoord, this.yCoord, this.zCoord);

	if (flag1) {
		this.markDirty();
	}
    }
}

 

You want to be looking at this:

if (flag != this.isInfusing()) {
			flag1 = true;
			CrypticInfuser.updateFurnaceBlockState(this.isInfusing(), this.worldObj, this.xCoord, this.yCoord, this.zCoord);

	if (flag1) {
		this.markDirty();
	}
    }

 

This never works, and hasen't worked.

 

When I do this:

if (flag = this.isInfusing()) {
			flag1 = true;
			System.out.println(isInfusing());
			CrypticInfuser.updateFurnaceBlockState(this.isInfusing(), this.worldObj, this.xCoord, this.yCoord, this.zCoord);

	if (flag1) {
		this.markDirty();
	}

 

It will work, but there's nothing here to say stop infusing if there not equal. Trust me I have tried else statements, if statements and i get all sorts of crazy glitches.

 

Here's the updateFurnaceBlockState method:

public static void updateFurnaceBlockState(boolean isInfusing, World world, int xCoord, int yCoord, int zCoord) {
	System.out.println("Here!");
	int i = world.getBlockMetadata(xCoord, yCoord, zCoord);
	TileEntity entity = world.getTileEntity(xCoord, yCoord, zCoord);
	TileEntityCrypticInfuser infuser = new TileEntityCrypticInfuser();
	keepInventory = true;

	if(isInfusing){
		System.out.println("HERE!");
		world.setBlock(xCoord, yCoord, zCoord, BlockHandler.blockCrypticInfuserActive);
	}else{
		world.setBlock(xCoord, yCoord, zCoord, BlockHandler.blockCrypticInfuserIdle);
	}

	keepInventory = false;
	world.setBlockMetadataWithNotify(xCoord, yCoord, zCoord, i, 2);

	if(entity != null){
		entity.validate();
		world.setTileEntity(xCoord, yCoord, zCoord, entity);
	}
}

 

You can see my println's for testing purposes. The first one println() is always reached by both of the different if statements I showed you in the updateEntity method(). The only one that gets the the second println() is the second if statement I showed you, that I said got it to turn on.

 

By the way, the first if statement: if(flag != this.isInfusing()) is how vanilla is written. Which makes my brain hurt even more. I'm very confused and not sure why this is happening.

 

Thanks shadowfacts for the code referencing, it helped me dig deeper into my code, and find different ways (that almost work). If you know of a way closer to vanilla that will work, I would love to know.

 

Thanks, any help is much appreciated!

Wow.. I' dumb. I got it to work, the reason was the flag boolean was returning whether or not the system had fuel. Not if it was actually infusing.

 

Now, I just need to figure out the second issue:

 

The furnace to the container/ the container to the furnace when shift clicking is messed up. Even if someone could point me to the specific class they think the problem would lie in, that would be great. I'm assuming there has to be a method in one of these classes that has to do with shift-clicking items. Maybe Its because I haven't overrode it yet.

 

If anyone has had this issue, or know where the shift clicking stuff occurs. In which class. I would love to know.

 

Thanks!

Hi

 

Brandon and I have written a 'MinecraftByExample' project for 1.8, one of the examples is a custom furnace.  It's a lot better documented than the vanilla code and the shift-click works exactly the same as 1.7.  You could look at it here  transferStackInSlot()  )  for some clues.

The main thing is - you must be very careful to keep track of which slot is which, it is easy to mix up the slot numbers of your combined container (eg 0-38) with the slot numbers of the components (i.e. player inventory 0 - 35 and your tile entity 0 - 2)

First off, you guys are great coders, and your organization is amazing. I also love how you use comments, one to help you, and also to help people like me. The transferStackInSlot im using is straight up vanilla code. Which now makes since why its not working. I have a fuel slot, 2 input slots, and an output slot. Vanilla uses only one input slot. I like how you defined variables as it makes your code very easy to read and nice and organized.

 

But I am still kind of confused what I would need to change the vanilla transferStackInSlot to in order for it to work with two input slots. I understand that it has to do with the number of slots. Like you said I believe my total slot number would be 39 though. Since player is 0-35 and my tile entity is 0-3.

 

I would love if you could just give a small example with how I would do this with my code. I know it seems fairly obvious to you. It's just all these numbers everywhere, I don't want to mess something up. I do understand conceptually what I need to be doing though.

 

Also for the fuel slot it uses a method called .getSmeltingResult() in the furnace recipe class. Since I have a custom recipe class, do you have any idea what I would do with that? Although not as important as my first question, I would love to know if you have the time.

 

Thanks

Ha, well I'm not sure about the great coder stuff but thanks for the positive feedback anyhow, glad you found it easy to understand :)

 

About the example - based on the order you're defining your slots you will have

0 = te slot 0

1 = te slot 1

2 = te slot 2

3 = te slot 3 defined with SlotCrypticInfuser

4 - 30 = player inventory slots

31 - 39 = player hotbar slots

 

So:

if slotNumber is 0 -3 (clicked on a furnace slot) , you should mergeItemStack(sourceStack, 4, 40, false) (i.e. into the player inv slots, or the hotbar if it's full)

if slotNumber is 4 - 39 (clicked on a player inv or hotbar slot), you should mergeItemStack into 0, 1, 2, or 3 depending on where you want the item to transfer to.

 

the .getSmeltingResult returns null if there's no recipe for that input.  So just call your custom recipe class with the input to see if it produces an output.  The logic is the same.
