Getting wrong slots?

[N1xx1]

Hello.

 

I'm encountering some problems with GUI and Containers.

 

Basically, my problem is that when I want to get some items from my inventory and put them wherever I want in the TileEntity or I want to move it inside my inventory strange things happen.

 

A simple example:

I have an item on ther fourth slot of my player inventory, I press that slot to move the item, and the as I do that the item return to the slot. I can't pick it in any way. But, if I have an item in the sixteenth slot, as I press the slot I get another item of 8 slots before, and when I place it down it behaves strangely.

 

I think it's caused by some wrong communication between the local server and the client, but I don't know what is wrong.

 

Some code:

        if(tileEntity instanceof TileEntitySomething){
            return new ContainerSomething(player.inventory, (TileEntitySomething)tileEntity);

The container class

public class ContainerSomething extends Container {

    public final TileEntitySomething tileEntity;
    public final InventoryPlayer inventoryPlayer;
    
    public ContainerSomething(InventoryPlayer ip, TileEntitySomething te){
        tileEntity = te;
        inventoryPlayer = ip;
        
        addSlotToContainer(new Slot(tileEntity, 0, 149, 17));
        
        
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 9; j++) {
                //                                           | id         | x         |  y        |
                addSlotToContainer(new Slot(inventoryPlayer, j + i * 9 + 9, 8 + j * 18, 84 + i * 18));
            }
        }

        for (int i = 0; i < 9; i++) {
            //                                         |id| x         |  y  |
            addSlotToContainer(new Slot(inventoryPlayer, i, 8 + i * 18, 142));
        }
    }
    
    @Override
    public boolean canInteractWith(EntityPlayer var1) {
        return true;
    }
    
    @Override
    // this is that method to handle shift click without the name, I think I have to update my MCP.
    public ItemStack func_82846_b(EntityPlayer player, int slot) {
        ItemStack stack = null;
        Slot slotObject = (Slot)inventorySlots.get(slot);

        //null checks and checks if the item can be stacked (maxStackSize > 1)
        if (slotObject != null && slotObject.getHasStack()) {
            ItemStack stackInSlot = slotObject.getStack();
            stack = stackInSlot.copy();

            //merges the item into player inventory since its in the tileEntity
            if (slot == 0) {
                if (!mergeItemStack(stackInSlot, 1, 37, true)) {
                    return null;
                }
            } else if (slot > 0) {

                return null;
            }

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

The TileEntity class

public class TileEntitySomething extends TileEntity implements IInventory, ISidedInventory {

    private ItemStack[] inv = new ItemStack[1];

    public TileEntitySomething(){

    }

    @Override

        ItemStack stack = getStackInSlot(slot);
        if (stack != null) {
            if (stack.stackSize <= amount) {
                setInventorySlotContents(slot, null);
            } else {
                stack = stack.splitStack(amount);
                if (stack.stackSize == 0) {
                    setInventorySlotContents(slot, null);
                }
            }
        }

        return worldObj.getBlockTileEntity(xCoord, yCoord, zCoord) == this && player.getDistanceSq(xCoord + 0.5, yCoord + 0.5, zCoord + 0.5) < 64;

        for (int i = 0; i < tagList.tagCount(); i++) {
            NBTTagCompound tag = (NBTTagCompound) tagList.tagAt(i);
            byte slot = tag.getByte("Slot");
            if (slot >= 0 && slot < inv.length) {
                inv[slot] = ItemStack.loadItemStackFromNBT(tag);
            }
        }
    }

    @Override

        super.writeToNBT(tagCompound);

        NBTTagList itemList = new NBTTagList();
        for (int i = 0; i < inv.length; i++) {
            ItemStack stack = inv[i];
            if (stack != null) {
                NBTTagCompound tag = new NBTTagCompound();
                tag.setByte("Slot", (byte) i);
                stack.writeToNBT(tag);
                itemList.appendTag(tag);
            }

    @Override
    public String getInvName() {
        return new StringBuilder().append(MyMod.id).append(".tile.something").toString();
    }

    @Override
    public int getStartInventorySide(ForgeDirection side) {
        return 0;

    @Override
    public int getSizeInventorySide(ForgeDirection side) {
        return 64;
    }
}

And the GUI constructor (of course it extends GuiContainer)

    public GuiSomething(InventoryPlayer playerinventory, TileEntitySomething tileentity){
        super(new ContainerSomething(playerinventory, tileentity));
    }

 

 

 

Well, I have no idea of what I'm missing...

 

Thank you.
