My mod crashes. Got to do with registerIcons?

[DarktStriker]

When I try to run my mod it crashes, I'm not 100% sure why but apparently it has got to do with registerIcons for my items and blocks. I have removed everything that had anything to do with icons, such as 'registerIcons'.

Here's the crash report:

Mmm, it seems that my code-viewer tool is broken. Can you post the code manually?

[DarktStriker]

yeah, what Class file do you want exactly?

[GotoLink]

Your custom ItemBlock is crashing when accessing #getSpriteNumber, that is what the error says.

[AlexStone]

can post the code that will help out to see what is problem.

[DarktStriker]

Okay.

Here's one of my custom block classes: https://gist.github.com/anonymous/b45758e554a9fab90e44

[sequituri]

I don't see the code for the ItemBlock that was constructed with a null Block. Could you post that?

 

p.s. The field field_150939_a in ItemBlock is your null.

If you try to register Icons in your custom ItemBlock class, you will get this crash. ItemBlocks should not register textures, since they use the Block rendering - i.e. whatever icons you register in your block will be used for the item. If you register icons in the ItemBlock, it attempts to register them to the Item sprite sheet, crashing your game when it tries to render because it is expecting the Terrain (block) sprite sheet. At least that's what seems to happen everytime someone registers an Icon.

 

Here is the code from vanilla ItemBlock#registerIcons:

@SideOnly(Side.CLIENT)
public void registerIcons(IconRegister par1IconRegister)
{
// note that Block#getItemIconName() returns null for all blocks except Hoppers
// so only hoppers will register an icon here (according to java-docs)
     String s = Block.blocksList[this.blockID].getItemIconName();

     if (s != null)
     {
         this.field_94588_b = par1IconRegister.registerIcon(s);
     }
}

Okay I went through all my block classes and none of them have field_150939_a .

And as for the code you gave me, it doesn't seem to work with 1.7.2...

If you read my post, you will see that the code is from vanilla ItemBlock, not Block, and I was not suggesting you use that code, it was merely demonstrating that ItemBlocks do not register icons, with one sole exception. Whether that sole exception is hard-coded other places, such as getting sprite sheets, I am not sure, but if you crash when registering an icon in an ItemBlock class, then it seems quite likely.

 

Did you try removing the registerIcons method from your ItemBlock classes, like I implicitly suggested?

[DarktStriker]

Okay, and yes I went through all the classes and removed them
