In a small project of mine, I'm attempting to code a side scrolling shooterific game for a friend. I've coded to the best of my ability, but... the code seems to have incredible issues with my choice of arrangement.
In the code below, state doesn't change for anything except ducking, in which it changes properly. All of ducking works fine, save that you can still jump while doing it, which is a byproduct of the .state not changing. Likewise, the jump sprite is displayed for 1/32 of a second when you do jump, but the state doesn't change. While you walk, it doesn't set the sprite, and for the life of me, I can't figure out why. It's probably some dumb mistake with if else statements that I missed, but I'm completely stumped. Would any of you care to take a shot at it?
