My mod added a suit of armor in a new material. Amazingly, that much works. However, when I take off my armor in creative mode (e.g. to enchant or repair pieces of it), the empty armor slots in my creative inventory are black squares instead of armor-piece outlines. Surprisingly, survival mode is unaffected.

 

It appears to be a small thing, but I've learned from unpleasant experience that even small visible defects can can spring from bugs that are doing worse behind the scenes. Therefore, I am trying to figure it out anyway.

 

I've walked through as much of the vanilla armor class as I can, and I didn't see how it could have been affected by what I modded in my armor class. I didn't even touch the method that registers those icons.

 

Then I tried commenting out my added creative tab. Voila! The empty slot icons returned to normal in creative mode.

 

Has anyone else noticed the slots turning black after adding a creative tab? Is it a forge bug, or a tutorial oversight, or must I have done something wrong?

 

My creative tab code:

 

tabTest = new CreativeTabs("Testing") {
	@Override
	@SideOnly(Side.CLIENT)
	public Item getTabIconItem() {
		return Items.brewing_stand;
	}
};

 

 

EDIT:

Looking at how vanilla tabs are instantiated, I noticed that they did not have the @Override annotation on getTabIconItem(). I removed it from mine, and the empty slots returned to normal. I don't know why, but the fix worked.

 

Somewhere out there is a tutorial that is teaching new modders like me to put that @Override in there. If anyone spots it, please ask the tutor to make a correction.

 

That @Override is actually good coding practice. Look it up.

 

What you saw is a vanilla bug when wearing any damaged armor in 1.7.2.
