Posted February 28, 20169 yr Simple (hopefully) question. How can I compare the itemstack in a slot with an itemstack that I am checking for. Eg. I am trying to check if slot index 0 has a diamond. I've tried just comparing the itemstack in the slot with new ItemStack(items.whatever) however that does not work presumably because certain data such as how long the item has existed for is different from a newly generated itemstack. Any help would be appreciated!
February 28, 20169 yr Author Minecraft does not like me using getItem on the itemstack returned from the slot check ( this.getStackInSlot(0).getItem() ), crashes and throws a NullPointerException, even though I'm making sure to check that it isn't null before executing any code using it. Crash report: http://paste.ee/p/CnMhU Tile Entity Class where the error is thrown: http://paste.ee/p/tyuNv (getItem checks around line 204) Help would be appreciated, and sorry for any hassle. EDIT: Whoops! Needed to make sure the ItemStack itself wasn't null before setting a variable to Itemstack.getItem()
February 28, 20169 yr What happens when the player does not have an item in that slot? Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice. Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked. DO NOT PM ME WITH PROBLEMS. No help will be given.
