RickWeek · July 14, 2017

Hi guys, i really need an help. I can't correctly add a custom gui to an entity. MC crash every time I try to interact with that entity. I post below all the code (The code was for 1.8.9 and i'm trying to port it to 1.10.2). Thanks if someone will be able to help

Post the FML log (logs/fml-client-latest.log in the game directory) using Gist or Pastebin. This will tell us why and where it's crashing.

This is the line 72:

saleprice = sneakysal.saleprice;

And the original declaration is (i have already tried to inizialied it to 1) :

public float saleprice;

The null variable is "sneakysal". Gui#initGui is called in the Gui classes constructor which gets called before your constructor and therefore it is not initialized. To fix this you can add a != null check and call Gui#initGui in your Guis constructor.

I tried to initialized the saleprice variable in the EntityClass and now the crashlog is this: https://pastebin.com/26ax3xYH

Did you change any code in your Gui at all?

RickWeek · July 14, 2017

This is the 1.8.9 code https://github.com/JordantheDewott/More-Creeps-and-Weirdos-Reboot-1.8.9/blob/master/main/java/fr/elias/morecreeps/client/gui/CREEPSGUISneakySal.java (it's not mine)

Ok, that is fine then you should know what a NullPointerException is. Look at the crash report where the error is printed it will be towards the bottom. It will point you towards the line that is making the error.
