Container: Function to check if Item is a specified Item

[Zcelo12]

Hello,

I made a container and everything works fine. Gui also. Now my problem is that i can put the container-item(right click opens the gui) into another container-item, if i have 2 of them.

Is there a funtion to check if the item is the container, then i mustn't put the item ind the container.

I hope you understand me

Look at the furnace code or the crafting table code, and see how they restrict you from placing an item in the output slot.

I looked into ContainerWorkbench, ContainerFurnace, TileentityFurnace and Tileentityworkbench, but i can't find the solution for my problem.

public boolean isStackValidForSlot(int i, ItemStack itemstack) {
	return true;
}

Thanks. I put this into my ContainerB.java , but i still can put the item into the container.

 

    public boolean isStackValidForSlot(int i, ItemStack itemstack) {
    	int id = itemstack.itemID;
    	if(id == Items.backpack.itemID)
    	{
    	        return true;
    	}
    	return false;
    }

 

My InventoryBackpack.java doesn't extend TileEntity. It extend InventoryBasic.

InventoryBasic might not have that functionality.

Open up that class in Eclipse and dig through it to see what's available.

I found that function in InventoryBasic, too. But why it doesn't work?

[Draco18s]

Also:

 

if(id == FoodExItems.backpack.itemID)
    	{
    	        return true;
    	}

 

If that code was working, that will only allow a backpack to be placed inside your item's inventory.

You mean my incomplete and non-selective code that uses tile entities?

(That is, it lets anything get placed into it, like a chest)

 

Don't think it'll help you much.

I dont need something selective Your code will help me but If you dont want to share no problem mate

I'm just saying that my code likely won't help

 

I have "takes everything slots" (like a chest) then two custom slots with don't accept input (like furnace output).

[godbaba]

I dont care what slots do you have slots which I cannot get working If you post your code Im sure it will be helpful for me :D

[Draco18s]

I'll have to dig it up later this evening.  Don't have a copy right now.
