Question

好的，我正在用python和pygame制作一个简单的游戏，你是一个宇宙飞船，不得不躲避流星。但是在添加流星并编写代码以使其随机生成并向下移动屏幕之后。我也有使用代码标签的问题，我会按Ctrl + K并在提供的空间内发布我的代码，它给了我代码错误。对不起，这是我的链接（不是最好的方式，我知道，我无法让代码标签工作。）

我的错误：

Traceback (most recent call last):
  File "C:\Users\fredd_000\Desktop\Pygame_Script.py", line 127, in <module>
    game_loop()
  File "C:\Users\fredd_000\Desktop\Pygame_Script.py", line 98, in game_loop
    things(thing_startx, thing_starty, thing_width, thing_height, black)
  File "C:\Users\fredd_000\Desktop\Pygame_Script.py", line 28, in things
    pygame.draw.circle(gameDisplay, color,[thingx, thingy, thingw, thingh])
TypeError: function takes at least 4 arguments (3 given)

发生错误的代码：

def things(thingx, thingy, thingw, thingh, color):
    pygame.draw.circle(gameDisplay, color,[thingx, thingy, thingw, thingh])

完整代码：

import pygame

pygame.init()

display_height = 800

gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('A Game By Freddie')

black = (0,0,0)
white = (255,255,255)
blue = (25,0,255)
red = (255,0,0)

car_width = 195
car_height = 1

clock = pygame.time.Clock()
gameExit = False
shipImg = pygame.image.load('ship.png')


def things(thingx, thingy, thingw, thingh, color):
    pygame.draw.circle(gameDisplay, color,[thingx, thingy, thingw, thingh])

    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((display_width/2),(display_height/2))

        x += x_change



        things(thing_startx, thing_starty, thing_width, thing_height, black)

            pygame.display.update()
        clock.tick(60)


game_loop()
pygame.quit()

您的代码存在的问题是您使用pygame.draw.circle()错误。使用该函数的语法是：pygame.draw.circle(screen, color, (x, y), diameter)。你可以说，你做的方式是pygame.draw.circle(screen, color, [x, y, w, h])。这是不正确的，圆圈没有宽度和高度。将您的代码更改为：pygame.draw.circle(gameDisplay, color, (thingx, thingy), thingw)。 thingw将是您圈子的直径。

您还应将功能参数更改为def things(thingx, thingy, thingw, color)。

如果您仍然对Pygame不熟悉或者对如何在屏幕上绘制形状感到困惑，我强烈建议您阅读，就像在评论中链接的Idos一样。
