Pygame检测图片之间的碰撞

Question

我对编程很新,最近我决定启动Pygame.根据我发现的教程,我创建了这个游戏.目的是观察球弹跳并通过在适当的时间点击使其远离底部的盒子.我知道代码有点混乱,但最大的问题是虽然代码运行,但是当球和盒子碰到时,游戏不会退出.

import sys, pygame
pygame.init()
size = width, height = 320, 240
speed = [2, 2]
black = 0, 0, 0
screen = pygame.display.set_mode(size)
ball = pygame.image.load("ball.bmp")
target = pygame.image.load("square_target.bmp")
ballrect = ball.get_rect()
clock = pygame.time.Clock()
target_place = [160, 200]
fps = 60

while 1:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: sys.exit()

    ballrect = ballrect.move(speed)
    if ballrect.left < 0 or ballrect.right > width:
        speed[0] = -speed[0]
    if ballrect.top < 0 or ballrect.bottom > height:
        speed[1] = -speed[1]
    if pygame.mouse.get_pressed()[0]:
        speed[0] = -speed[0]
    if ballrect <= target_place[0] + 50 or ballrect <= target_place[1] + 50:
        pygame.event.post(pygame.QUIT)

    screen.fill(black)
    screen.blit(ball, ballrect)
    screen.blit(target, target_place)
    pygame.display.flip()
    fps += 0.01
    print (fps)
    clock.tick(fps)

有帮助吗？

Pygame包含一个内置方法来检查两个矩形是否重叠.因此,如果满足以下条件:

ballrect.colliderect(target.get_rect())

......这意味着两个图像重叠.
