Solved[1.8] Getting the texture from an Item/Block so can render it as 2D in GUI

Hey before IIcon and the like was tossed out [1.7.x] I had my GUI draw the 16x16 texture in my GUI, I upgraded to [1.8] and seems like this is no longer an option to just get the regular texture to render. How can I get the face or flat 2D display image of an Item or a Block. Blocks more preferred, here is my old code. The new code is just using GL to draw flat color squares which is not what I want.

This is all the old code before I had to butcher it and comment sections out just to get it to work at all. Any help to get the new [1.8] stuff to work would be great, as I want this gui to be given a list of blocks and let the player pick what one they want to draw with to build a blueprint, but to be able to use anything from even other mods.  Right now it is a fixed static list of blocks (which I do not want, just used as I was making this to get started quicker)

You can iterate through the GameRegistry and check for blocks to add to your inventory - I would use a regular Container / IInventory / GuiContainer triplet to handle it, then you won't need to worry about rendering at all.

 

However, if you do choose to go with direct rendering, it is still possible - check out RenderSnowball. It uses a RenderItem instance (which you can get from Minecraft class) and then you pretty much just call 'renderItem.renderItemModel(ItemStack)'. Of course you'll want to mess around with it some to make it look nice in the GUI if it doesn't naturally, in which case I'd recommend you to check out GuiContainer.

Thanks for the Pointers, I will dig into those and if I still have trouble I shall be back.

 

EDIT:

Well managed to get it to work, didn't think the line of code would be this long conga-line

"Minecraft.getMinecraft().getRenderItem().getItemModelMesher().getItemModel(new ItemStack(block)).getTexture()"

just so I can use the GUIs draw textured rec.

 

Thanks guys.
