我怎样才能让我的敌人投射攻击玩家无论玩家移动到哪里？

Question

我有一个敌人会发射弹丸，但只向右侧射击我希望它向任何位置的玩家射击带我把如何做的步骤告诉我，那太好了，谢谢

这就是我所做的，它只向右侧射击我希望它在玩家所在的任何位置向玩家射击

   for shootss in shootsright:
       if shootss.x < 500 and shootss.x > 0:
           shootss.x += 7
       else:
           shootsright.pop(shootsright.index(shootss))
   if len(shootsright) < 1:
           shootsright.append(Bools(round(enemyshoots1.x+enemyshoots1.width-107),round(enemyshoots1.y + enemyshoots1.height-50),(0,0,0)))

这是我的子弹课

# enemys bullets
ksud = pygame.image.load("heart.png")
class Bools(object):
  def __init__(self, x, y,color):
      self.x = x
      self.y = y
      self.ksud = pygame.image.load("heart.png")
      self.hitbox  = self.ksud.get_rect()
      self.rect  = self.ksud.get_rect()
      self.rect.topleft = (self.x,self.y)
      self.speed = 10
      self.color = color
      self.hitbox = (self.x + 57, self.y + 33, 29, 52) # NEW
  def draw(self, window):
       self.rect.topleft = (self.x,self.y)
       player_rect = self.ksud.get_rect(center = self.rect.center) 
       player_rect.centerx += 0 # 10 is just an example
       player_rect.centery += 0 # 15 is just an example
       window.blit(self.ksud, player_rect)
       self.hitbox = (self.x + 97, self.y + 33, 10, 10) # NEW
       window.blit(self.ksud,self.rect)

我的敌人班

shotsright = pygame.image.load("shooting2.png")
shotsleft = pygame.image.load("shooting1.png")
class enemyshoot:
   def __init__(self,x,y,height,width,color):
       self.x = x
       self.y =y
       self.height = height
       self.width = width
       self.color = color
       self.shootsright = pygame.image.load("shooting2.png")
       self.shotsleft = pygame.image.load("shooting1.png")
       self.shootsright = pygame.transform.scale(self.shootsright,(self.shootsright.get_width()//3,self.shootsright.get_height()//3))
       self.shotsleft = pygame.transform.scale(self.shotsleft,(self.shotsleft.get_width()//3,self.shotsleft.get_height()//3))

       self.rect = pygame.Rect(x,y,height,width)
       self.health = 10
       self.hitbox = (self.x + -20, self.y + 30, 31, 57)
   def draw(self):
       self.rect.topleft = (self.x,self.y)
       window.blit(self.shootsright,self.rect)
       self.hits = (self.x + 20, self.y, 28,60)
       pygame.draw.rect(window, (255,0,0), (self.hitbox[0], self.hitbox[1] - 60, 50, 10)) # NEW
       pygame.draw.rect(window, (0,255,0), (self.hitbox[0], self.hitbox[1] - 60, 50 - (5 * (10 - self.health)), 10))
       self.hitbox = (self.x + 60, self.y + 80, 81, 87)

black = (0,0,0)
enemyshoots1 = enemyshoot(1100,240,100,100,black)        
enemyshooting = [enemyshoots1]

这是我的完整代码

查看您的脚本对我没有多大帮助，因为您要维护许多不同的类。

   for shootss in shootsright:
       if shootss.x < 500 and shootss.x > 0:
           shootss.x += 7

这里显示，当您更新项目符号 x 坐标时，您正在使用正常数值递增它。

然后你在你的子弹类中像这样更新它。

   window.blit(self.ksud,self.rect)

你可以做的是让子弹速度改变它的方向。你可以使用这样的代码

if object_you_want_to_follow.x > object_shooting_the_bullet.x:
    bulletSpeed = +7
elif object_you_want_to_follow.x < object_shooting_the_bullet.x:
    bulletSpeed = -7

如果您想沿 y 方向垂直跟随，同样适用。

优化提示

据我了解，在您的项目符号类中使用它并没有什么不同，因为您很快就会对其进行更新。

   window.blit(self.ksud, player_rect)

编辑

为了让事情变得更容易，你可以简单地这样做

   for shootss in shootsright:
       if shootss.x < 500 and shootss.x > 0:
           if enemy.x < playerman.x:
               shootss.x += 7
           else:
               shootss.x -= 7
       else:
           shootsright.pop(shootsright.index(shootss))
   if len(shootsright) < 1:
           shootsright.append(Bools(round(enemyshoots1.x+enemyshoots1.width-107),round(enemyshoots1.y + enemyshoots1.height-50),(0,0,0)))
