[1.7.10]Double furnace causes unexpected error

Recommended Posts

Hi, I made a double furnace in an older version of MCF and now I'm updating it, however, I get an "unexpected error" (null pointer) when the onBlockActivated() method is called. Help?

Did you register your GUI handler?

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.

Null pointers are usually pretty easy to figure out compared to other errors. In your

onBlockActivated()

, there are a few things that could cause it (not limited to these two cases though):

[*]

world.getTileEntity()

, if

world

is null

[*]

player.openGui()

, if

 player

is null

 

Check if those are null when you run the code (using prints or your preferred method).

 

Basically, any time there is a

variable.something

, where

something

isn't static, you can potentially cause a null pointer, if

variable

is null.

 

Edit:

 

Actually, check the code inside of

NetworkRegistry.getLocalGuiContainer()

. There should be some variable that is incorrectly null inside that function. You can set a break point in that function and see exactly which line breaks when you run using debug mode. Then you can check what each variable is inside debug mode. It might also be caused by your

getClientGuiElement

returning null sometimes. Instead of just returning null, it's helpful to put some sort of notice when you reach that part of code. For example, you can put

System.err.println("something went wrong");

right before you return null.

So I did some debugging and the getClientGuiElement is never called, it will cut before it even gets there. It does seem to be something with getLocalGuiContainer() but I can't figure out how to fix it.
