这是一篇关于莱斯大学在Coursera上的Python课程的课后作业，涉及RiceRock游戏的实现。玩家通过键盘控制飞船躲避陨石并发射导弹，使用SimpleGUI库创建游戏界面。

RiceRock类似于小时候玩的沙罗曼蛇和雷电游戏（当然这里都是最简单的版本，毕竟入门。。。），玩家可以控制一个太空飞船，键盘↑键控制飞船加速度，↔键控制方向（顺时针和逆时针），Space键发射导弹，来击毁太空中不断生成和移动的陨石，并统计得分。游戏截图如下：

该交互式程序使用了SimpleGUI库进行界面设计，具体代码如下：

# program template for Spaceship
import SimpleGUICS2Pygame.simpleguics2pygame as simplegui
import math
import random

# globals for user interface
WIDTH = 800
HEIGHT = 600
score = 0
lives = 3
time = 0
started = False

class ImageInfo:
    def __init__(self, center, size, radius = 0, lifespan = None, animated = False):
        self.center = center
        self.size = size
        self.radius = radius
        if lifespan:
            self.lifespan = lifespan
        else:
            self.lifespan = float('inf')
        self.animated = animated

 	def get_center(self):
        return self.center

    def get_size(self):
        return self.size

    def get_radius(self):
        return self.radius

    def get_lifespan(self):
        return self.lifespan

    def get_animated(self):
        return self.animated
