Hi everyone.

I have a little bug with my own block that is currently called TrialInventory. I have also container for this block. I followed one tutorial for container creation, but it was for 1.6.4(I had no choice because I found only this tutorial), but some things were broken(code for some things in 1.6.4 was not equivalent to same thing code for 1.7.10), that means I had to replace broken code with other code.

I thinked it will work fine. Well it worked fine, except shift-click. When I moved item from my inventory to container, it worked fine, but when I moved this item back, it duplicated it's amount.

I searched for the bug in my code and on forums so long, but with no result. With that bug, it is only CHEAT MACHINE, not basic storage block. I really want to fix this bug. Can you help me?

And, if you decide to delete this topic, please, PM me with the reason why you delete this topic.

 

My code:

 

 

Block code:

package com.ec.blocks;

import com.ec.Main.MainRegistry;
import com.ec.Main.TabTMPI;
import com.ec.handler.GuiHandler;
import com.ec.lib.RefStrings;
import com.ec.screen.ScreenTrialInventory;
import com.ec.tileentity.TileEntityTrialInventory;

import cpw.mods.fml.common.registry.GameRegistry;

import net.minecraft.block.Block;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class BlockTrialInventory extends BlockContainer{

protected BlockTrialInventory()
{
	super(Material.glass);
	this.setCreativeTab(TabTMPI.tab);
	this.setBlockTextureName(RefStrings.MODID + ":BlockPlacer");
	this.setBlockName("blockTrialInventory");
}

public static Block block;

public static void mainRegistry()
{
	block = new BlockTrialInventory();
	GameRegistry.registerBlock(block, block.getUnlocalizedName());
}

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

@Override
public boolean onBlockActivated(World world, int x, int y, int z, EntityPlayer player, int metadata, float what, float these, float are)
{
	TileEntityTrialInventory tileEntity = (TileEntityTrialInventory) world.getTileEntity(x, y, z);
	player.openGui(MainRegistry.instance, 0, world, x, y, z);
	return true;
}

}

 

Container:

package com.ec.container;

                        for (int inventoryCollomuns = 0; inventoryCollomuns < 1; inventoryCollomuns++)
                        {
                                addSlotToContainer(new Slot(tileEntity, inventoryCollomuns + inventoryRows * 3, 62 + inventoryCollomuns * 18, 17 + inventoryRows * 18));
                        }
                }
                bindPlayerInventory(inventoryPlayer);
        }

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


        protected void bindPlayerInventory(InventoryPlayer inventoryPlayer) {
                for (int i = 0; i < 3; i++) {
                        for (int j = 0; j < 9; j++) {
                                addSlotToContainer(new Slot(inventoryPlayer, j + i * 9 + 9, 8 + j * 18, 85 + i * 18));
                        }
                }

                for (int i = 0; i < 9; i++) {
                        addSlotToContainer(new Slot(inventoryPlayer, i, 8 + i * 18, 142));
                }
        }

        @Override
        public ItemStack transferStackInSlot(EntityPlayer player, int slot) {
                ItemStack stack = null;
                Slot slotObject = (Slot)inventorySlots.get(slot);
                
                if (slotObject != null && slotObject.getHasStack()) {
                        ItemStack stackInSlot = slotObject.getStack();
                        stack = stackInSlot.copy();
                        
                        if (slot < 9)
                        {
                                if (!this.mergeItemStack(stackInSlot, 0, 35, true)) {
                                        return null;
                                }
                        }
                        
                        else if (!this.mergeItemStack(stackInSlot, 0, 9, false)) {
                                return null;
                        }

                        if (stackInSlot.stackSize == 0) {
                                slotObject.putStack(null);
                        } else {
                                slotObject.onSlotChanged();
                        }

                                return null;
                        }
                        slotObject.onPickupFromSlot(player, stackInSlot);
                }
                return stack;
        }
}

 

TileEntity *It has _common in name because I have new version that only extends TileEntityInventoryBase that I made because storing slot data in NBT tag compound is so hard.
