错误1

Question

我正在尝试用pygame制作游戏，但我得到了两个错误。

错误1

我的分数在游戏中突然增加，我的条件是一次只增加1点。我提高分数的代码是：

 if thing_starty >display_height:
            thing_stary = 0-thing_height
            thing_startx= random.randrange(0,display_width)
            dodged += 1
            thing_speed += 1
            thing_width += (dodged * 1.2)

此处躲过的是我的分数，每当该区块离开屏幕时它应该增加一。

错误2

在我的游戏中，从顶部开始有一个黑色矩形，但事情就是一旦它从屏幕上消失，它就不会再回来。在块越过屏幕之外，即使没有碰撞，游戏也会结束。
要返回的块的代码是：

 if thing_starty >display_height: #Check if block is there in the screen or not
            thing_stary = 0 - thing_height
            thing_startx= random.randrange(0,display_width)
            dodged += 1
            thing_speed += 1
            thing_width += (dodged * 1.2)

是食物形象非常感谢老乡们，非常感谢关注这个错误。

Answer 1

您的变量名称中有拼写错误，可能是：

thing_starty

而不是：

thing_stary

为什么得分在pygame中会突然增加？
