前言
接以上多篇文章解绍arcade游戏编程的基本知识，回归主题，继续完善孩子的梦想，坦克大战，学习单词，搭建整体的框架，主要包括，游戏的开始界面，进行界面，结束界面，角色控制，子弹发射，地图加载，英语单词显示，提示，分数显示，爆炸显示及精灵，敌人自动寻路，开火，碰撞检测等，初具模型，慢慢加载完善。
整体解绍
1、坦克大战3–未完，只是功能初具
1.1 文件结构
1.2 类
界面类：guigl
粒子类：particle
基本设置：seting_tank
角色类：tank
1.3 角色类
1.4 粒子类
1.5 主程序框
1.6 main函数
注释处，为了调试方便，不显示开始界面，直接进行主程序
def main():
“”“主函数”“”
window = arcade.Window(SCREEN_width, SCREEN_height, SCREEN_title)
# menu_view = MainMenu()
menu_view = GameView()
window.show_view(menu_view)
arcade.run()
