Python:rect参数无效 [英] Python: rect argument is invalid

问题描述

我正在尝试学习python，但我遇到了这个问题，当我运行程序时，它说rect参数无效，这是我的代码:

Hi I'm trying to learn python and but i'm stuck with this problem, when i run my program it says rect argument is invalid, this is my code:

import pygame
pygame.init()

win = pygame.display.set_mode((500,500))

pygame.display.set_caption("First game")

x = 50
y = 50
width = 40
height = 60
vel = 5

run = True
while run:
    pygame.time.delay(100)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    pygame.draw.rect(win, (255, 0, 0),(x, y, width, height, vel))
    pygame.display.update()

pygame.quit()

错误:

Traceback (most recent call last):
 File "...", line 25, in <module>
   pygame.draw.rect(win, (255, 0, 0),(x, y, width, height, vel))
TypeError: Rect argument is invalid

推荐答案

pygame.draw.rect 必须是包含4个元素的元组:

The 3rd argument of pygame.draw.rect has to be a tuple with 4 elements:

pygame.draw.rect(win，(255，0，0)，(x，y，width，height，vel))

pygame.draw.rect(win, (255, 0, 0),(x, y, width, height))

或者，它可以是 pygame.Rect 对象:

Alternatively it can be a pygame.Rect object, too:

rect = pygame.Rect(x, y, width, height)
pygame.draw.rect(win, (255, 0, 0), rect)
