python - “Rect argument is invalid”

Question

我一直在尝试编写游戏代码，但它一直给我一个"rect argument is invalid"错误。如果有人可以告诉我我在做什么错，那太好了。我相信它与代码中的列表和元组有关，但是我已经对其进行了彻底的审查，但它无法正常运行。该代码只是不断向我显示相同的错误消息。
我的代码:

import pygame
import sys
import random

pygame.init()

Width = 800
Height = 600

Red = (255, 0, 0)
Blue = (0, 0, 255)
White = (255, 255, 255)
backgroundColor = (0, 0, 0)

playerSize = 50
playerPos = [100, 300]

columnSize = [50, 150]
columnPos1 = [700, random.randint(0,random.randint(0,100))]
columnPos2 = [700, random.randint(0,random.randint(400,500))]

screen = pygame.display.set_mode((Width, Height))

game_over = False

clock = pygame.time.Clock()

while not game_over:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
            
        if event.type == pygame.KEYDOWN:

            x = playerPos[0]
            y = playerPos[1]

            if event.key == pygame.K_LEFT:
                x -= 20
            elif event.key == pygame.K_RIGHT:
                x += 20
            elif event.key == pygame.K_UP:
                y -= 20
            elif event.key == pygame.K_DOWN:
                y += 20
            
            playerPos = [x,y]

    screen.fill(backgroundColor)
    if columnPos1[0] >= 0 and columnPos1[0] < Width and columnPos2[0] >= 0 and columnPos2[0] < Width:
        columnPos1[0] -= 10
        columnPos2[0] -= 10
    else:
        columnPos1[0] = 700
        columnPos2[0] = 700

        columnPos1[1] = [700, random.randint(0,random.randint(0,100))]
        columnPos2[1] = [700, random.randint(0,random.randint(400,500))]

    pygame.draw.rect(screen, Red, (playerPos[0], playerPos[1], playerSize, playerSize))
    pygame.draw.rect(screen, Red, (columnPos1[0], columnPos1[1], columnSize[0], columnSize[1])) #this is where rect is invalid
    pygame.draw.rect(screen, Red, (columnPos2[0], columnPos2[1], columnSize[0], columnSize[1])) #here as well

    clock.tick(30)

    pygame.display.update()

添加后，错误开始发生

columnPos1[1] = [700, random.randint(0,random.randint(0,100))]
columnPos2[1] = [700, random.randint(0,random.randint(400,500))]

Answer 1

columnSize是[50, 150]，因此您的rect参数看起来像

(columnPos1[0], columnPos1[1], [50, 150], [50, 150])

你可能是说

(columnPos1[0], columnPos1[1], columnSize[0], columnSize[1])
