Hi all, i've recently tried to make my first GUI for minecraf 1.6.4 but i've been having severe trouble after about 8 hours of searching the internet it still isn't working, there have been several bugs mixed together i think incuding a desync between player and server caused by calling player.openGUI not FMLNetworkHandler.openGui, some weird slot index errors and some other just weird errors, the current errors that i need help fixing are as follows:

- my shift click code is weird, ghost items used to appear, stacks didn't decrement, but now i just get a StackOverflow error in the console that looks like this:

- when you double-click an item the stack size is weird (e.g if i fill my inv with single stacks of stone and double click sometimes it will give me a 29 stack but hen i do it again a 31 and when i do it again the correct size of 36)

- sometimes you can't pick up items in your inventory

- sometimes left click will act as right click in the GUI slots

 

 

Here is the important parts of my load class (NOTE: the spoiler/code button in the post editor isn't working(or i'm doign it wrong)):

mergeItemStack is a boolean, do you mean return false?

i tried making mergeitemstack return false and making drymerge return 0 but that didn't change anything

making mergeitemstack return true isn't doing anything either - i think the errors in transferstackinslot

I just tested and making transferStackInSlot return null stops crash on shiftclick but i can't pick up items with regular click

edit: sometimes you can pick items up, it has a weird offset on slot( 1.g click in what should be slot 0 and you pick up the itemstack in slot 29), double click still duplicates/deletes items sometimes, rightclick and leftclick still sometimes switch what they do and serveral other weird things

bump

could someone atleast post working code for me to compare mine against? (I would need working, tested 1.6.4 forge 9.11.1.953 (i think that's the right number, might have got some decima points the wrong way around)), also since 1.7 forge is out (so i've heard) would you recommend that i update ASAP and fix all errors first or get a stable beta version of my mod before i update?

Ok, here's a container I have

 

https://github.com/Draco18s/Artifacts/blob/master/draco18s/artifacts/block/BlockPedestal.java

https://github.com/Draco18s/Artifacts/blob/master/draco18s/artifacts/entity/TileEntityDisplayPedestal.java

https://github.com/Draco18s/Artifacts/blob/master/draco18s/artifacts/client/GuiContPedestal.java

https://github.com/Draco18s/Artifacts/blob/master/draco18s/artifacts/inventory/ContainerPedestal.java

 

I think that's everything except the custom slot (it is just set to allow only certain item types)

Thanks for the code but still no luck, i've tried copying off the forge forums, ive tried copying that code you pasted, i've tried copying youtube tutorials and i've tried tweaking the code from all of the above for hours, still no luck however i did override  'public ItemStack slotClick(int slot, int button, int flag, EntityPlayer player)' and put some debug in it before passing it to super and found out that it's getting the correct slot that you click on with the correct itemStack but when you try it in the GUI you're actually picking up the stack two to the right and one above, after lots of editing i think it's taking one above because it is somehow creating the 'slot indexes' for the hotbar wrong(when you click slot 0 the method gives you the number slot 29 and when you feed that back into this.inventorySlots you still manage to get the same itemStack0 and the 2 to the right is caused by there being 2 slots in the tileEntity part of the GUI (i think as it has 2 slots). Also if it helps the slotClick method is only being called client side

anyone have any ideas?

bump

anyone know? please, this is really important for my mod without working GUIs the mod can't do much
