Has anyone actually bought "construct 2 game development by example", and tried the tutorials in it? I'm on chapter 6 "Making a Tower Defense game", and something doesn't seem to be right on that one. I've started over on that about 5 times and get to the same point in the step by step instructions and the game does not do what it should when I test it. I'm not sure if I'm just doing something wrong or if the book has something written incorrectly or missing steps... In one in the instructions it has you trying to make a turret shooting a projectile and I could not get that to work until I added a bullet behavior to the projectile. The book never mentioned that in any of the steps. The only reason I figured out to add the bullet behaviour was from watching some of the tutorial videos on the Scirra website.
