So i'm still trying to replace the default container GUI for some blocks, now when i open the GUI the game crashes and it gives me a NullPointerException. I've uploaded all the code to a github repository, i'm really desperate with this :( Any kind of help will be really appreciated, here is the github link

Don't blame me if i always ask for your help. I just want to learn to be better :)

it's always the problem of the indexOutOfBounds :( Also the EntityPlayerMP is null, why? :/

Don't blame me if i always ask for your help. I just want to learn to be better :)

You're still indexing a 0..45 array with index=46. It's time for you to set a break point (or four) and run your code in debug mode. The firat thing you must figure out is why the array has only 46 elements when you thought you added 4. You thought you had 50 slots, so where did that array come from that it has only 46?

 

Put your debug hat on and do some sleuthing!

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.
