I'm trying to figure out how to assign an empty slot of a container with a texture.

 

It looks like Forge added some stuff to the Slot to have the ability, but when I look at the GUI Container code that would utilize it, doesn't seem like it will work.

 

Anyone have any experience around this?

To the existing container?

I think the Container#addSlotToContainer will work.

For texture, use Slot#setBackgroundIcon.

I found that, but if you trace out the GUI, when it gets that icon from slot, it will only use the standard Minecraft texturemap.

 

I don't see a way to point it at anything new. 

 

I got this to work for the normal helmet, chest ect.

 

I'm looking to do the same thing with a peice of custom armor.  It won't utilize anything but the standard 4.

 

Is this making sense?

Ah then you can use the Slot#setBackgroundIconTexture Method

The following is the relevant code where Slots are rendered.

 

That does not look like to me it is using whatever texture you input.  It is using the default minecraft items.png file.

 

Do you see it differently?

 

 

            IIcon iicon = p_146977_1_.getBackgroundIconIndex();

            if (iicon != null)
            {
                GL11.glDisable(GL11.GL_LIGHTING);
                this.mc.getTextureManager().bindTexture(TextureMap.locationItemsTexture);
                this.drawTexturedModelRectFromIcon(i, j, iicon, 16, 16);
                GL11.glEnable(GL11.GL_LIGHTING);
                flag1 = true;
            }

[/spoiler]

Then I think you have to register an icon via registerIcons.

I think it is similar with the item textures...
