NBT data item Icons

[Draco18s]

AFAICT, this is the only spot where an ItemStack is passed to the Item class in order to get an icon for drawing inventory sprites (as opposed to 3D world sprites).  Unfortunately it's final and cannot be overriden (base class editing out the final gets me what I need).

 

All it does is call

getIconFromDamage(int par1)

, which doesn't have enough info left to get at stack NBT data.

 

public Icon getIcon(ItemStack stack, int renderPass, EntityPlayer player, ItemStack usingItem, int useRemaining)

(which calls

public Icon getIcon(ItemStack stack, int pass)

, am already overriding) won't work, as that's the 3D render usage (apparently).

 

The only other function available is

public Icon getIconFromDamageForRenderPass(int par1, int par2)

which also lacks the ItemStack.

 

Lex has indicated that this must be possible as other mods are doing it, but my guess is that they've written a custom item renderer to handle it (which seems...excessive, as the necessary function is already there, but not modifiable).

That does work.  Thanks.

 

Already had that function overriden (getIcon) but I didn't think to set multiple render passes (and actually, you want that second function to return a 2:

//default
    public int getRenderPasses(int metadata)
    {
        return requiresMultipleRenderPasses() ? 2 : 1;
    }
