按你的想法改好了，问题主要有几个：
一、你对边界的限制的几个变量应该作为属性放在__init__下面，并且和self绑定，下面对应的方法下的同名变量也改为同样的名字。
二、主函数main中的rect在Myplane类中叫做myplane_1_rect，所以没有rect这个属性报错。
三、rect.center是一个坐标元组，无法被修改，所以你应该改成按键改变left，top这些可修改的量。
四、运行的时候你应该就发现了，飞机的移动非常不流畅，这就是事件中操作移动带来的问题了，所以建议把整个代码改成小甲鱼课程里用的
key_pressed = pygame.key.get_pressed()
if key_pressed[K_w] or key_pressed[K_UP]:
pass
if key_pressed[K_s] or key_pressed[K_DOWN]:
pass
if key_pressed[K_a] or key_pressed[K_LEFT]:
pass
if key_pressed[K_d] or key_pressed[K_RIGHT]:
pass
这种类型，具体的代码自己思考一下吧。
