PythonPygame移动图片当我

Question

我想创造一个游戏。我想要一个图片跟随鼠标光标，但只有在我点击。我试着给它编程，但画面只出现了，然后又消失了。但我希望它跟随鼠标光标直到我再次单击。下面是代码的一部分：

if mouse.get_pressed()[0]==1:
        clicked = "yes"
    if clicked=="yes":
        while 1:
            screen.blit(explosive_bootle_obr,(mouse_position))
            if mouse.get_pressed()[0]==1:
                break

如果需要，这里有一个完整的代码：

Answer 2

你内心的while循环似乎是错的。你知道吗

如果使用blit（）但从不使用flip（），屏幕将永远不会实际更新。你知道吗

所以删除你的第二个while，取消它的内容，并可能以不同的方式处理“clicked”变量。你知道吗

编辑： 另外，如果您使用所描述的事件here会更好
