开发目标：实现小红帽所挂脚本的自动生成
下图为生成的最终目标
本项目是从json中读取角色场景等信息，因此为了更好地判断所用属性是否需要，设置为bool类型，False表示在c#代码中注释掉该类属性，True代表使用该属性（属性暂时设置为）

Timer = True # 计时器
speed = False # 速度
IsTrigger = True # 触发器
start_point = True # 起始位置
localScale = True # 起始大小

仔细观察生成的结果，代码与目标生成的代码基本一致，（注释暂时只能使用英文编辑。） 随即把生成的代码放在unity中，观察运行情况。
运行前：
运行后：
可见，小红帽的控制器实现基本无误。 具体视频已放在b站：
unity的2d的animation纯代码实现，场景切换。
