I'm creating a mod called Mo' Tools, and I keep getting a crash when using my own custom Tool Material.

The crash report I'm getting is this:

I'm not sure why this is happening? I've followed numerous tutorials and they all say to do the same thing, but it doesn't work for me.

 

I can use existing Tool Materials, such as EnumToolMaterial.IRON, but not custom ones.

 

The line creating the Tool Material:

 

public static EnumToolMaterial AZURITETOOL = EnumHelper.addToolMaterial("AZURITETOOL", 2, 400, 6.0F, 2, 14);

 

 

And my tool load method:

 

azuritePickaxe = new azuritePickaxe(azuritePickaxeID, AZURITETOOL).setUnlocalizedName("azuritepickaxe");

 

 

Can anyone help me?

The 3rd and 4th line down from 'java.lang.NullPointerException' in the crash report suggest that the error occured in your program on the 13th line of azuritePickaxe.java on the init command (whatever that is, as far as i am conserned that only occurs in the main mod file but it could be a different init) and on line 75 of motools.java when running the load void/function. Not having the full java file, i really cant help you other then saying that something is wrong which is obviosly apparent. If you can paste said lines of the code then i think that i can help you a bit more :)

13th line of azuritePickaxe.java:

super(id, enumToolMaterial);

 

75th line of motools.java:

azuritePickaxe = new azuritePickaxe(azuritePickaxeID, AZURITETOOL).setUnlocalizedName("azuritepickaxe");

 

 

Eclipse can't find any errors here, and neither can I really, so...?

I have found a fix, and while inconvenient; I've installed the very latest MCForge and re-written my mod, and it seems to have worked. If anyone can find a more convenient fix, I'd be grateful, but if not don't worry

Sorry to say, but thats just bullshit.

@HydroBane: can you post your complete mod file?

i know but him´s code was right and if the code is right the problem is minecraft forge everyone needs to know.

I think it is the forge version. I've updated and re-wrote my mod (I didn't get very far so it wasn't a long job), and it works. It was Forge version 1.5.1-7.7.1.629, just for future reference.
