For some reason, I am getting an ArrayIndexOutOfBounds exception from the item obsidianaxe when I load up the game. The other two tools I have added (obsidianpickaxe and obsidiansword) have no problems at all, and I used the same structure to create this item.

 

Here is the GitHub repo: https://github.com/InterdimensionalCat/ModTest

 

The classes effected are:

ObsidianAxe: https://github.com/InterdimensionalCat/ModTest/blob/master/java/com/benthom123/test/items/ObsidianAxe.java

ModItems: https://github.com/InterdimensionalCat/ModTest/blob/master/java/com/benthom123/test/ModItems.java

and CommonProxy: https://github.com/InterdimensionalCat/ModTest/blob/master/java/com/benthom123/test/proxy/CommonProxy.java

 

And here is the crash log:

As the stacktrace indicates an issue assigning the attack value, I tried lowering the attack value of my obsidian material, but that didn't change anything.

 

Since the issue was in registering items, I thought that I might be registering too many items using this method. However looking at other registry for 1.12.2 this does not appear to be the case either.

 

Any help would be greatly appreciated!

 

 

Use the constructor that takes 2 floats.

Thanks, it is loading without error now. From what I understand this means that axes have set possible attack speed and attack damage values. Is there a way to override these values when making an axe? (IE: an axe with even less attack speed than what is possible in the array)

 

 

EDIT: nvm the constructor allows for that already and I didn't realize it
