Question

我有一个游戏，用户可以使用箭头键移动玩家（“mrhinckleberg”）。还有两个敌人＆＃34;它会自动上下跳动。

我现在如何检测玩家与敌人之间的碰撞？

这是我到目前为止的代码：

import pygame
import time
pygame.init()
window = pygame.display.set_mode((800,800))
pygame.display.set_caption("Yues")
theboard = pygame.image.load('theboard.png')
enemy = pygame.image.load('mrenemy.png')
mrhinckleberg = pygame.image.load('MrHinckleBerg.png')
mrhincklebergdead = pygame.image.load('MrHinckleBergdead.png')
deathscreen = pygame.image.load('deathscreen.png')
black = (0,0,0)
clock1 = pygame.time.Clock()
def quitt():
    pygame.quit()
    quit()
playerx = 750
playery = 450
enemydirection = 'down'
enemyx = 500
enemyy = 50
enemyspeed = 100
enemydirection2 = 'up'
enemyx2 = 350
enemyy2 = 750
enemyspeed2 = 50
enemydirection3 = 'down'
enemyx3 = 200
enemyy3 = 50
enemyspeed3 = 150


while True:
    window.blit(theboard, (0,0))
    if enemydirection == 'down':
        enemyy += enemyspeed
        if enemyy >= 790:
            enemydirection = 'up'
    elif enemydirection == 'up':
        enemyy -= enemyspeed
        if enemyy <= 10:
            enemydirection = 'down'


    if enemydirection2 == 'up':
        enemyy2 -= enemyspeed2
        if enemyy2 <= 10:
            enemydirection2 = 'down'
    elif enemydirection2 == 'down':
        enemyy2 += enemyspeed2
        if enemyy2 >= 790:
            enemydirection2 = 'up'

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            quitt()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_RIGHT:
                playerx += 12
            elif event.key == pygame.K_LEFT:
                playerx -= 12
            elif event.key == pygame.K_UP:
                playery -= 12
            elif event.key == pygame.K_DOWN:
                playery += 12
    if playerx == enemyx and playery == enemyy:
           print("hai")
    window.blit(theboard, (0,0))
    window.blit(mrhinckleberg, (playerx,playery))
    window.blit(enemy, (enemyx,enemyy))
    window.blit(enemy, (enemyx2,enemyy2))
    window.blit(enemy, (enemyx3,enemyy3))
    pygame.display.update()

在我的观点中，问题是您检查变量playerx 是否等于到enemyx，但是由于您更改了{{1}，这将永远不会成立仅在特定间隔中添加变量（加或减12）。

要避免这种情况，您可以检查enemyx / playerx和playery / enemyx是否在某个范围内**：

enemyy

请注意，Python中的比较可以链接。这意味着if (playerx <= enemyx <= playerx + playerWidth) and \ (playery <= enemyy <= playery + playerHeight): print("hai")相当于5 < x <= 10。有关详细信息，请参阅Built-in Types -> Comparisons。

更新的代码：

5 < x and x <= 10

我希望这会有所帮助：）
