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,它不会改变按钮的颜色。你知道吗
我怎样才能使这个方法改变按钮的颜色?你知道吗
提前谢谢!你知道吗
仅仅更改sprite的
colour
属性是不够的,还必须更改image
,因为pygame在调用buttonsGroup.draw(screen)
时会将图像blit到屏幕上。你知道吗我会在
__init__
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时,通过将当前图像指定给self.image
来交换它们。你知道吗相关问题 更多 >
