pygame中的python单击事件范围问题
我使用python pygame库创建了一个GameObject类,它在屏幕上绘制了一个矩形。 我想集成一个事件处理程序,它允许我画一个矩形,但是游戏对象的点击事件没有注册。 下面是该类的几段代码:pygame中的python单击事件范围问题,python,scope,mouseevent,pygame,Python,Scope,Mouseevent,Pygame,我使用python pygame库创建了一个GameObject类,它在屏幕上绘制了一个矩形。 我想集成一个事件处理程序,它允许我画一个矩形,但是游戏对象的点击事件没有注册。 下面是该类的几段代码: def on_事件(self,event): def on_-draw(自,表面): 我是否需要将rect变成一个图像,以便注册鼠标事件,或者是否有其他方法可以拖动此框 我是否需要将rect变成一个图像,以便注册鼠标事件,或者是否有其他方法可以拖动此框 不需要图像。解决方案: 注: 您已经使用事件获
