Question

我是一个相对较新的python开发人员，我偶然发现了一个问题。我无法使用pygame.sprite.collide_rect（）函数，我无法在网上找到任何解决方案。这是我的代码：

import sys
import pygame

pygame.init()

gameDisplay = pygame.display.set_mode((600,600))

pygame.display.set_caption('Doge Adventures')

gameexit = False

white = (255,255,255)
black = (0,0,0)

move_x = 300
move_y = 300

def checkCollision(sprite1, sprite2):
    col = pygame.sprite.collide_rect(sprite1,sprite2)
    if col == True:
        sys.exit()

while not gameexit:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            gameexit = True
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
            move_x -= 15 
        elif event.key == pygame.K_RIGHT:
            move_x += 15
        elif event.key == pygame.K_UP:
            move_y -= 15
        elif event.key == pygame.K_DOWN:
            move_y += 15

gameDisplay.fill(white)

b1 = pygame.draw.rect(gameDisplay, black, [move_x, move_y, 40, 40])
b2 = pygame.draw.rect(gameDisplay, black, [450 , 450, 50, 50])

b1,b2

checkCollision(b1,b2)

pygame.QUIT()
quit()

我得到的错误是：

Traceback (most recent call last):
  File "C:\Users\DEREK\My Documents\LiClipse Workspace\Doge           Adventures\Game.py", line 45, in <module>
    checkCollision(b1,b2)
  File "C:\Users\DEREK\My Documents\LiClipse Workspace\Doge     Adventures\Game.py", line 19, in checkCollision
    col = pygame.sprite.collide_rect(sprite1,sprite2)
  File "C:\Python26\lib\site-packages\pygame\sprite.py", line 1147, in     collide_rect
    return left.rect.colliderect(right.rect)
 AttributeError: 'pygame.Rect' object has no attribute 'rect'

顺便说一下，我正在使用python 2.7

pygame.sprite.colliderect方法用于检查精灵之间的碰撞，而不是正在使用的矩形。精灵是pygame.sprite.Sprite类的实例。你试图检测的是矩形之间的碰撞，它们有自己的碰撞检测方法：b1.colliderect(b2)。矩形不是精灵，精灵不是矩形。

没有类的Pygame碰撞
