用pygame做了一个2D横板格斗游戏。
代码是自己写，图片是网上找的，角色的动画是用开源软件LPC character gen0.9生成的。
就是幻影剑舞。当然这个图片仅仅用来做游戏开发学习，不商用！
背景图片是用下面这张图片利用移位和循环播放效果制作成动态的游戏背景，看起来像是不断有月球经过。
# 更新背景
background_x_1 -= background_speed
background_x_2 -= background_speed
if background_x_1 <= -background_width:
background_x_1 = background_width
if background_x_2 <= -background_width:
background_x_2 = background_width
# 绘制背景
win.blit(background_image, (background_x_1, 0))
win.blit(background_image, (background_x_2, 0))
有两个游戏音乐特效，一个是背景音乐，一个是游戏结束提示音。
一共两个类， fight类和Boss类。

实现功能如下：
左边的角色1 可以 左右移动，上下跳跃（通过键盘上的方向键）。
左边的角色1 可以发动远程攻击，类似剑气一样, 攻击的时候会触发动画切换（其实就是切换图片）。
右边的角色2 可以发动冲击波攻击。
左边的角色1按下D键可以进入防御状态
防御状态下受到攻击生命值不会受到削减。
每个角色上面都有一个血条值，受到一次攻击会削减10%，任何一个角色的生命值为0时游戏结束。
