I'm messing around with XNA in a very simple Minecraft-esque world I'm making and I'm wondering how I can do the "breaking the block" visuals in XNA.
If you're unfamiliar with the game, you begin interacting with the cube and based one what tool you're using, the block will take X amount of time to break. There's about 10 different stages of cracking that the cube will display before the cube breaks. I'm curious about how to display those 10 stages of cracking on top of the original skin of the block.
I know the game works using a Sprite sheet to color the blocks. This sprite sheet does not include every possible design at every possible stage of breaking the block, each stage is a different sprite with some transparency.
In short, how can I quickly and efficiently overlay a texture on a surface that already has a texture?
Do I have to combine them? If so, how?
