Hello,
What an amazing tutorial. I don't get why it pop so late in my quest for "how to do normal mapping lighting" .... XD
I play a little with your example to see if I could use it with the way I'm drawing stuff onscreen and I have a question :
You use the Setup object to draw the robo with draw_self() but what if I assign my character's sprite dynamically, using draw_sprite and a Finite State Machine ? Is there a way to not have this normal bug and keep using my character's own draw-event ?
