Python 更改一个类,以便当鼠标悬停在该类上时,它会更改颜色-Pygame
我有这个类来定义和创建Pygame中的按钮。此时,当鼠标悬停在按钮上时,它不会改变颜色。我试图在类中添加另一个方法,以便在鼠标悬停在按钮上时,它会改变颜色。但是,当我运行HoveredOver方法时,它不会更改按钮的颜色Python 更改一个类,以便当鼠标悬停在该类上时,它会更改颜色-Pygame,python,pygame,Python,Pygame,我有这个类来定义和创建Pygame中的按钮。此时,当鼠标悬停在按钮上时,它不会改变颜色。我试图在类中添加另一个方法,以便在鼠标悬停在按钮上时,它会改变颜色。但是,当我运行HoveredOver方法时,它不会更改按钮的颜色 import pygame as pg import sys import time # All pygame stuff under here pg.init() # Font definitions backFont = pg.font.SysFont("monospa

我如何使此方法能够改变按钮的颜色
提前谢谢 仅仅更改精灵的
颜色
属性是不够的,您还必须更改图像
,因为pygame在您调用按钮Group.draw(screen)
时会将图像显示在屏幕上
我会在\uuuu init\uuuu
方法中创建图像,或者将它们作为参数传递,然后在鼠标悬停在按钮上方时,通过将当前图像分配给self.image
来交换它们

如果我错了,请纠正我,但我相信行
super().init()
应该是super()。\uuu init\uuu()
@MichealO'Dwyer你在哪里看到super().init()
?我可能看到了super().init()
没关系。对不起,麻烦了。
