[SOLVED][1.8] Help with Custom Crafting Table that holds items inside its slots

NovaViper · December 30, 2014

The game keeps on crashing every time I try to open up the GUI for the custom crafting table that has a tile entity (since it has a custom design). Here is my code:

TileEntity

public class BlockNileWorkbench extends BlockContainer{


public BlockNileWorkbench() {
	super(Material.wood);
	this.setCreativeTab(ZeroQuest.ZeroTab);
	this.setHardness(2F);
	this.setResistance(12.5F);
	this.setStepSound(soundTypeWood);
}
    private Random rand = new Random();

    @Override
public TileEntity createNewTileEntity(World world, int par1) {
	return new TileEntityNileWorkbench();
}

    @Override
public int getRenderType(){ //RenderBlocks for Render type//
	return -1;		
}
    
    @Override
public boolean isOpaqueCube(){
	return false;		
}
    
    @Override
    public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumFacing side, float hitX, float hitY, float hitZ)
    {
        if (worldIn.isRemote)
        {
            return true;
        }
        else
        {
            TileEntity tileentity = worldIn.getTileEntity(pos);

            if (tileentity instanceof TileEntityNileWorkbench)
            {
                playerIn.displayGUIChest((TileEntityNileWorkbench)tileentity);
            }

            return true;
        }
    }
    
    public void breakBlock(World worldIn, BlockPos pos, IBlockState state)
    {
        TileEntity tileentity = worldIn.getTileEntity(pos);

        if (tileentity instanceof IInventory)
        {
            InventoryHelper.dropInventoryItems(worldIn, pos, (IInventory)tileentity);
            worldIn.updateComparatorOutputLevel(pos, this);
        }

        super.breakBlock(worldIn, pos, state);
    }
}

Also, I have the 1.7.10 Code posted up on Github: https://github.com/NViper21/ZeroQuest

Does anyone know how to fix this?

Anyone have any idea how to successfully accomplish this?

Nephroid · January 4, 2015

The code that you posted is extremely broad. Believe it or not, it takes time to analyze code to identify what's going wrong, and the more code you post, the longer it takes. If it takes too long, people might give up. Therefore, narrowing your code down will help others help you. A good way to narrow down your search is to use breakpoints and debug mode.

In Eclipse, to set a breakpoint, right click on the left edge of the text area, and select "toggle breakpoint":

You can set breakpoints in the forge library code too, not just the code that you have written. When you start running in debug mode, when the code reaches a breakpoint, it will pause BEFORE executing that line. When the program is paused, you can check the values of every variable at that point in the program by mousing over them:

To narrow down your code, set a bunch of breakpoints in your code. When you reach one without any errors, you know that all the code before that breakpoint works. As soon as you get an error, you know that the error must be caused by something in between the last breakpoint and the current breakpoint.

Using this technique, you can more precisely identify the portion of code that is causing the problem. You might even figure out the problem yourself in the process.

Looking at the stack trace (error messages), try setting breakpoints at these locations (the numbers are most likely line numbers):

net.minecraftforge.fml.common.FMLCommonHandler.callFuture(FMLCommonHandler.java:677)

net.minecraft.inventory.InventoryBasic.<init>(InventoryBasic.java:33) ~[inventoryBasic.class:?]

Then look at what values are null. In the segment you posted above,

blockType

is

null

, which may or may not cause problems. There might be other null variables that you should check too. If you see any bit of code of the form

variable.something

and

variable

is null, that's will cause a null pointer.

Well when you figure out your crash, remove

public void onContainerClosed(EntityPlayer playerIn)
    {
        super.onContainerClosed(playerIn);

        if (!this.worldObj.isRemote)
        {
            for (int i = 0; i < 9; ++i)
            {
                ItemStack itemstack = this.craftMatrix.getStackInSlotOnClosing(i);

                if (itemstack != null)
                {
                    playerIn.dropPlayerItemWithRandomChoice(itemstack, false);
                }
            }
        }
    }

Because thats the code that dispenses the items after you exit the workbench

The problem is I don't know WHY it's crashing. The debugger doesn't even let me into the world, which basically doesn't even allow to test out the breakpoints in the tileentity and the container. I finally got it to where it doesn't crash when you first open it, but now if I leave the world and re-enter, it crashes immediately. Also when I open up the GUI, it's the completely wrong GUI (its a chest's gui instead of a crafting table) The code that is on my github worked perfectly in 1.7.10. The code of the progress I did so far is in the previous post I made

========EDIT==========

Ok so now I got it where it doesn't crash from closing the client all together and re-enter the world or from just leaving the world and re-entering that same world and to even keep my stuff inside the container (though I'm not sure if its even using my custom container since the gui is wrong). What I did to fix that problem was replace the getBlockMetadata() method in the readFromNBT in the TileEntity and removed that onContainerClosed() method completely out of my custom container. But now my new problem is that it's still displaying the incorrect GUI. What do I do now?

NovaViper · January 5, 2015

Ok, I completely scratched out the 1.8 source codes and went back to the 1.7.10 codes and modified them and the result I got is:

+The GUI is displaying the right one (not the chest gui)

+Items stay inside the container aftering leaving the world and re-entering and closing client

+No crashing upon leaving and re-entering the game, opening the GUI

But the downside is:

-When trying to get the crafting result item, the client crashes and this error is thrown:

If I am correct then your problem is the acheivment and the slots of your crafting table.

NovaViper · January 6, 2015

I removed the slot stuff and changed something in my achievement events and it now works. Thanks for your help guys!
