Hello,

at the moment i'm trying to do a itembackpack, which is like a chest, but you do not have to place it in the world.

You craft a item and simply make right click to open a gui. But when i make right click nothing happens.

In my mod_File i added:

NetworkRegistry.instance().registerGuiHandler(this, new GuiHandler());

 

I do not want to post the whole mod_File because there are many things i've added already for other items and blocks.

Now i want to include a backpack. Hope someone can help me.

 

Has someone an ideal?

player.openGui(mod_FoodEx.instance, 0, world, 0, 0, 0);

 

And from GUI handler:

TileEntity tileEntity = world.getBlockTileEntity(x, y, z);

                if(tileEntity instanceof TileEntityBackpack){

 

The XYZ passed inn will always be 0, so it will get the TileEntity at 0,0,0 which probably ain't an instanceof TileEntityBackpack.

 

I think you may have to re think what you are trying to do, you're logic is flawed mate.

Also it is not right to use a TileEntity without a block. Use the NBT system the ItemStack provides!

Is there a tutorial, how to do that with items? I only found it with blocks, and have no idea, where to start.

I've already changed the 0,0,0 in openGUI to the player position, but this can't work. I have to use NBT, i understand, but i need some information or a tutorial.

There's not a tutorial for everything, this is where tutorials stop and one have to start to act like a programmer and study source code, study what other people have done and read the documentation

 

But regarding NBT, I believe that there are some tutorials involving nbt inn general around

Thanks. I read through the Internet and got it already a bit working. I can open a gui and place something in it. But what are the functions to save the Items, that are in the "Backpack", and load them? I don't use TileEntity anymore, cuz it's an item.

That would be the functions to save and load nbt data as mentioned inn the above linked text:)

Ok, doesn't thought it was for items, too. I'll try it.

Hello, it's me again. I've a small question. Where do I've to save the items with writeToNBT ? Loading the items at onItemRightClick, right?

Can someone help me with loading and saving the content?

I tried somehting but i didn't work.
