[1.12.2]Calling ItemStack array in casted tileentity crashes world

tebreca · November 18, 2017

So hello everybody, i was trying to make a tile entity for a machine that would onky accept items in special slots, but when it calls the update statement, i instantly get a exeption, i tried to debug but i didn't found anything. Do i send packets in the wrong way?

code for TE:

import net.minecraft.tileentity.TileEntity;

public class TileAssembler extends TileEntity{
	public ItemStack[] inv = new ItemStack[3];

	public ItemStack getInv(int meta) {
		return this.inv[meta];
	}

	public void setInv(ItemStack inv, int meta) {
		this.inv[meta] = inv;
	}

	public void refresh() {
		if(inv[0].getItem()==Items.DIAMOND_HOE&&inv[1].getItem()==ItemInit.copperGear) {
			if(world.getBlockState(pos.add(0, 1, 0)).getBlock()==BlockInit.casingWooden) {
				world.setBlockState(pos.add(0, 1, 0), BlockInit.harvester.getDefaultState());
				inv[0]=null;inv[1]=null;
			}
		} else if (inv[2].getItem()==Items.DIAMOND_PICKAXE&&inv[3].getItem()==ItemInit.ironGear) {
			if(world.getBlockState(pos.add(0, 1, 0)).getBlock()==BlockInit.casingWooden) {
				world.setBlockState(pos.add(0, 1, 0), BlockInit.blockbreaker.getDefaultState());
				inv[2]=null;inv[3]=null;
			}
		}
		
	}

Just now, diesieben07 said:

The word "update" does not occur anywhere in your post or code except here. What is this "update statement" you speak of?

And "an exception" is not helpful, post the stacktrace.

im sorry i meant update method, (morning brain)

There is no "update method" anywhere in the code you posted.

And you still did not provide the stacktrace.

i mean the refresh method, its the method which updates the block when clicked

Don't implement ITileEntityProvider. To add a TileEntity to your block, override hasTileEntity and createTileEntity.

In your OnBlockActivated the meta variable starts counting at 0 and then gets incremented 4 times. You use it after every increment, so you end up using values 1 through 4. Then you call setInv on your tile entity with that, but setInv can only accept values 0 through 3, because it accesses an array of length 4. Even if that does not crash because out of sheer luck you don't have the right things in your inventory, the inv array in your TileEntity will end up containing null values, which your refresh method does not handle (it just calls methods on the values in inv).

Your formatting is all over the place and you don't follow Java naming conventions. Please don't do this...

ok, thx
