前言
接上篇文章继续解绍arcade游戏编程的基本知识。
坦克类，地图，角色的控制，声音等前期学习的汇总
1、坦克类
代码实现
# _*_ coding: UTF-8 _*_
"""
坦克键盘控制转弯，及按角度前进与后退

2、title地图加载
2.1设置，tank类的引入
from arcadegame.guigl import *
from arcadegame.mysprite import *
from arcadegame.tank import *
2.2 角色的引入
# 添加角色.

self.wanjia.center_y = PLAYER_start_y
self.scene.add_sprite("wj", self.wanjia)

self.scene.add_sprite("wj",self.wanjia)
