Ok so first of I'm assuming its the container that's not working correctly. I've been updating to 1.8 and this is the first major issue I've run into. Well more like two problems.

 

One of my Tile Entities will accept an item however it will immediately spit it back out but create a copy of the item in the correct slot with a stack size of zero.

 

The other Tile Entity just eats the item and nothing happens.

 

I copied my code over from 1.7.10, and using TheGreyGhost's MinecraftByExample updated it to 1.8. I'm not entirely sure where exactly my issue is so if you need anything to help just let me know.

 

Any help is much appreciated.

 

Container that spits item out:

 

 

public class ContainerCrusher extends ContainerHC

{

private int lastCrushTime;

private TileEntityCrusher tileEntity;

 

public ContainerCrusher(InventoryPlayer inventoryPlayer, TileEntityCrusher te)

{

this.addSlotToContainer(new Slot(te, 0, 56, 34));

this.addSlotToContainer(new Slot(te, 1, 116, 34));

this.addSlotToContainer(new Slot(te, 2, 8, 62));

this.addPlayerSlots(inventoryPlayer, 8, 84);

 

this.tileEntity = te;

}

 

@Override

public void addCraftingToCrafters(ICrafting p_75132_1_)

{

super.addCraftingToCrafters(p_75132_1_);

p_75132_1_.sendProgressBarUpdate(this, 0, this.tileEntity.getCrushTime());

p_75132_1_.sendProgressBarUpdate(this, 1, this.tileEntity.getCrushTime());

 

p_75132_1_.func_175173_a(this, this.tileEntity);

}

 

@Override

public boolean canInteractWith(EntityPlayer playerIn)

{

return tileEntity.isUseableByPlayer(playerIn);

}

{

}

}

 

this.lastCrushTime = this.tileEntity.getField(0);

}

 

@Override

public ItemStack transferStackInSlot(EntityPlayer player, int slotIndex)

{

Slot slot = (Slot) this.inventorySlots.get(slotIndex);

 

if (slot != null && slot.getHasStack())

{

ItemStack itemstack1 = slot.getStack();

itemstack = itemstack1.copy();

 

//Change accordingly from here...

if (slotIndex < 3)

{

if (!this.mergeItemStack(itemstack1, 3, 39, true))

{

return null;

}

}

else

{

if (itemstack1.stackSize == 1)

{

for (int i = 0; i < 3; i++)

{

//Shift click single items only

Slot shiftedInSlot = ((Slot) inventorySlots.get(i));

if (!shiftedInSlot.getHasStack() && shiftedInSlot.isItemValid(itemstack1))

{

mergeItemStack(itemstack1, i, i + 1, false);

}

}

return null;

}

}

//..to here.

 

if (itemstack1.stackSize == 0)

{

slot.putStack((ItemStack) null);

}

else

{

slot.onSlotChanged();

}

 

if (itemstack1.stackSize == itemstack.stackSize)

{

return null;

}

 

slot.onPickupFromSlot(player, itemstack1);

}

Base Container

 

 

public abstract class ContainerHC extends Container

{

protected void addPlayerSlots(InventoryPlayer playerInventory, int x, int y)

{

for (int i = 0; i < 3; ++i)

{

for (int j = 0; j < 9; ++j)

{

addSlotToContainer(new Slot(playerInventory, j + i * 9 + 9, x + j * 18, y + i * 18));

}

}

 

for (int i = 0; i < 9; ++i)

{

addSlotToContainer(new Slot(playerInventory, i, x + i * 18, y + 58));

}

}

}

 

 

Did you open the Gui and Container on the client or server side?
