我正在使用 pygame 和 random 模块在 python 中编写一个 2D 游戏，我遇到了一些代码问题。一个问题是，两个玩家都没有受到任何伤害，每颗子弹击中每个玩家 100 点生命值应该造成 10 点伤害(子弹和玩家都是 Sprite )。第二个问题是，我想要一种让两个玩家碰撞而不是相互重叠的方法，而不是刺入函数，也许使用 pygame.sprite.collide_rect()，所以如果你能帮助解决这个问题，我可以得到去掉 stabbed 函数，可以省去第三个问题。第三个问题，我的 stabbed 函数是重复“玩家 1 获胜”和“玩家 2 获胜”，当两个玩家互相接触时。 谢谢!`

最佳答案
在游戏循环中，玩家的生命值迅速初始化为 100。在循环之前初始化玩家的健康一次。清除子弹组，这在游戏重新开始时很重要:
player_health = 100
player2_health = 100
for bullet in bullets:
bullet.kill()
for bullet in bullets1:
bullet.kill()
while not gameExit:
# [...]
检查容器 bullets1 中的子弹是否击中 player 并检查容器 bullets 中的子弹是否击中 player2 :
for bullet in bullets1:
if pygame.sprite.collide_rect(bullet, player):
bullet.kill()
player_health -= 10
break
if player_health == 0:
died()
for bullet in bullets:
if pygame.sprite.collide_rect(bullet, player2):
bullet.kill()
player2_health -= 10
break
if player2_health == 0:
died1()
跳过将单个独立项目符号添加到 all_sprites 组:
all_sprites.add(bullet1)
all_sprites.add(子弹)
两个玩家的条形颜色混淆了:
pygame.draw.rect(gameDisplay, player_health_color, (1080, 25, player_health, 25))
pygame.draw.rect(gameDisplay, player2_health_color, (20, 25, player2_health, 25))
pygame.draw.rect(gameDisplay, player2_health_color, (1080, 25, player2_health, 25))
pygame.draw.rect(gameDisplay, player_health_color, (20, 25, player_health, 25))
Bullet 和 Bullet2 类的update 方法存在问题。你必须分别测试 self.rect.left self.rect.right，而不是 self.rect.bottom:
def update(self):
self.rect.x += self.x_change
if self.rect.left > display_width: # self.rect.left instead of self.rect.bottom
self.kill()
if self.rect.right < 0: # self.rect.right instead of self.rect.bottom
self.kill()
