No I mean the Block that I was talking about above

Do I replace the return new BasicGui(player.inventory, (BasicTileEntity) tileEntity) with the thing I suggested? because I can only return one or the other Also, if I wanted to say create a backpack, how on right click with the backpack item, it would open a chest inventory and store the contents in the item, would I only need a IGuiHandler and a GuiContainer, or those 2 and a container? That's the line you need to replace. I haven't done anything with backpack type stuff, but i know what you need: Something with IInventory A GuiContainer class A Container class A GuiHandler (you already got one) Now when I right-click the block, it opens the gui then immediately closes it. Any suggestions?

So should I do something like return new BasicContainer(player.inventory, (BasicTileEntity) tileEntity); in the getServerGuiElemet method?

I've just started learning modding for Minecraft(have been for 3 days). I'd say I'm close to intermediate when it comes to Java(been programming w/ it for about 8 months constantly). I have been trying to create, basically, a chest, from an outdated tutorial(which also didn't really explain the code). I got all of the error part out of the code(as in there is no red squiggle under the code), and when I click on the block to open it, it quickly displays the GUI, then the game immediately crashes. Sorry if this seems like a "noob" question or anything, I am pretty beginner at this EDIT: Can a mod help me out with this format?
