So I was following along MineMaarten video tutorials about modding on 1.7.10 and it came to a part where a tile entity would store an ItemStack and change the associated block texture with the texture from the Item the player right clicked. The thing is on 1.7.10 you would use the getIcon method to retrieve the block IIcon and from there it's pretty easy. Now on 1.10 there's no getIcon. In fact it seems all very different with the block states and all. So how would you go about doing that on 1.10? If someone would be so kind to explain to me, I would like to understand how to retrieve a block texture and/or how to set it. Thanks!
