'pygame.Rect' 对象不可调用 [英] 'pygame.Rect' object is not callable

问题描述

代码:

import pygame , sys, time, random
from pygame.locals import *

def enemie():
    global speed, ball
    ball.y += speed
    if ball.y == 602:
        ball = pygame.Rect(random.randint(0, 450), 0 ,20,20)

def blast():
    global bl, blast
    blast.y = bl


def player_animation():
    global player_speed, playerx
    player.x = player_speed



pygame.init()
running = True

clock = pygame.time.Clock()

speed = 7
bl = 1
player_speed = 1



ball = pygame.Rect(random.randint(0, 450), 0 ,20,20)
player = pygame.Rect(250, 450, 50, 50)
blast = pygame.Rect(300, 0 ,20,20)
screen = pygame.display.set_mode((500, 500))


while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
                running = False
    enemie()
    player_animation()
    blast()
  
    screen.fill((255, 255, 255)) #color

    
    pygame.draw.ellipse(screen, [255, 0, 0], ball)
    pygame.draw.ellipse(screen, [0, 0, 255], player)
    pygame.draw.ellipse(screen, [0, 255, 0], blast)
    
    if ball.colliderect(player):
        pygame.quit()
        sys.exit()
        

    keys=pygame.key.get_pressed()
    if keys[K_LEFT] and player.x !=  -4 :
        player_speed -= 5

    if keys[K_RIGHT] and player.x !=  451:
        player_speed += 5

    if event.type == pygame.MOUSEBUTTONDOWN:
        bl += 5
    pygame.display.flip()
    
    clock.tick(30)
pygame.quit()

错误:

line 54, in <module>
    blast()
TypeError: 'pygame.Rect' object is not callable

我正在尝试创建一些会移动的球.当我点击时，绿色的球或爆炸应该会移动，错误是否意味着有一个 ) 或一个 ( 不属于?但我找不到我的错误......我以前遇到过这个错误，我不记得我是如何解决它的.什么是错误是什么意思?我该如何解决?提前致谢！

I am trying to create some balls that move. and the green ball or blast is supposed to move when I click, Does the error mean that there is a ) or a ( that doesn't belong? But I can't find my mistake... I've had this error before and I can't remember how I solved it. what does the error mean? and how can I fix this? thanks in advance!

推荐答案

你的全局 blast 变量 阴影 blast 功能.当您调用 blast() 时，blast 不再定义为函数，而是一个 pygame.Rect.该错误告诉您不能像函数一样调用 Rect.

Your global blast variable shadows the blast function. By the time you call blast(), blast is no longer defined as a function, but is a pygame.Rect instead. The error is telling you that you can't call a Rect like a function.

更改其中之一的名称，以免它们发生冲突.

Change the name of one of them so they don't collide.
