Processing Game Help

Sun Dec 10 19:05:37 EST 2017

Hello all! I've been trying to create a game in Python Processing where a spaceship moves horizontally in order to miss a collision with an asteroid. I'm having difficulty making it so that the game quits when an asteroid hits the spaceship, could anybody help? Here is my code. As you can see, I tried using globals in order use variables from previous classes, but nothing has worked. For this specific approach, no error message popped up, but nothing happened either. Thanks so much!
