Hey, sorry if this question has been asked already, but I'm trying to make a superhero game. I downloaded Hulk and Spider-Man sprites, and I want to make a long stair case. My idea was that the hulk would destroy the lower steps, while Spidey climbs the steps. The only problem is that the steps I made won't fall, they just hang in the air. Plus, they look messy. And they keep falling through my floor sprite.
So I'd like to know:
1) How do you make a neat pile of bricks?
2) How do you make the bricks fall?
3) How do I keep them from falling through the floor sprite?
