Hey, I've been stuck on a bug for a few days here and was wondering if anyone had any ideas.

 

EDIT: I've made a Git for my project, if that's easier to see https://github.com/xandayn/StorageCraft

 

EDIT2: I ended up just rewriting all the code for the diamond chest and now it works, never found out the exact issue of the bug though.

 

EDIT3: So looking through my old code and comparing to my new code I realized my mistake, in the GuiHandler class I'm checking for a TileEntityGoldChest where I should be checking for a TileEntityDiamondChest, just thought I'd make that note incase anyone was having a similar issue.

I'm really baffled by this issue, basically I have a four(two complete and two still in progress) chests sharing the same block id and using metadata to determine which chest it is and which tileentity to use for it only the diamond chest is having issues, the two other chests that I've programmed have all worked perfectly, only the diamond one I've made is having an issue, but it's literally exactly the same as my other previous chests. I'm not sending any custom packets currently, I think I must be overlooking something but I can't find the issue to save my life, I'd really appreciate a little bit of help.

Hi

 

The basic problem seems to be that you are trying to store 108 ItemStacks into a chest with only 45 slots.  So I would suggest putting a breakpoint into Packet104WindowItems.processPacket and then have a look at the container to see why it only has 45 slots instead of the expected 108.  I'm guessing either it's the wrong container, or you haven't set it up right.

Thanks for the reply, so I did what you suggested and put a break in to check what we'd see, and the ItemStack array is the correct size.21dn7ed.png
