Recommended Posts

make sure your GUI extends GuiContainer and make a new class extending Container and give the player.inventory to that container

 

im cleaning up some code then post it for you

 

also check the wiki for "tiny chest" its a very basic and very usefull example

Thanks for the basics. Appreciate. Now I want to "hand back" the ItemStack when it isn't one which I allow. For example my inventory should ONLY hold sticks. This is what I ment with the players hand in the first place. Whenever you click a slot with an item that is not a stick nothing should happen. Can someone figure it out how to do THAT?

 

Thanks for the fast respond, I like it :D

hum, do you want the player to be able to place other items in his inventory with the vanilla E menu, because if you want to limit an item placement ONLY in a certain modded gui you can extends Slot and theres a method to prevent such thing  (its called isStackValid or something like that)

I found this method (which is in IInventory, I believe). The problem is that the auto-sorting, placing, etc. algorithms just don't use it ..... which is of course kinda obnoxious. Hm extending Slot... I dunno I thought about overriding the slotClick(int, int, int, EntityPlayer) method from Container but I don't know what all those parameters are. Does anyone know more about the handed vars?

Well... what ever. I now use my own Slots extending Slot (the slot-sensitive version of isItemStackValid() IS called) and have rewritten the transferStackInSlot() method. This thing is on fire now. Thanks for sharing your knowledge with me.
