我在为A Level计算项目制作的太空侵略者程序中显示了一个额外的精灵，这是一个问题。
看起来像这样：
我的代码如下所示：
class Enemy(pygame.sprite.Sprite):
def __init__(self,x,y,direction,enemy_type):
pygame.sprite.Sprite.__init__(self)
self.EnemyType = enemy_type
self.Direction = direction
if enemy_type == 1:
enemy_image = pygame.image.load("sprites\\enemy1_1.png")
self.Speed = 1
self.Score = 5
if enemy_type == 2:
enemy_image = pygame.image.load("sprites\\enemy1_1.png")
self.Score = 15
self.Speed = 1
if enemy_type == 3:
enemy_image = pygame.image.load("sprites\\enemy1_1.png")
self.Score = 10
self.Speed = 1
if enemy_type == 4:
enemy_image = pygame.image.load("sprites\\enemy1_1.png")
self.Score = 20
self.Speed = 1
if enemy_type == 5:
enemy_image = pygame.image.load("sprites\\enemy1_1.png")
self.Score = 25
self.Speed = 1
self.image = pygame.Surface([100, 100])
self.image.set_colorkey(BLACK)
self.image.blit(enemy_image,(0,0))
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
def move_enemy(self):
if self.Direction == "right":
self.rect.x += self.Speed
if self.Direction == "left":
self.rect.x -= self.Speed
#draw image
def draw(self, screen):
screen.blit(self.image, self.rect)
allEnemies = pygame.sprite.Group()
a_enemies = Enemy(50,50,"right",1)
allEnemies.add(a_enemies)
#For X coords
spawnPositions = [100,200,300,400,500,600,700]
yCoord = 10
#creating enemies
for n in range(5):
for i in range(len(spawnPositions)):
xCoord = spawnPositions[i]
enemy_type = random.randint(1,5)
enemy = Enemy(xCoord, yCoord,"right", enemy_type)
allEnemies.add(enemy)
yCoord = yCoord + 50
#update enemy positions
loop = 0
for enemy in (allEnemies.sprites()):
if enemy.rect.x < 5:
enemy.rect.y = enemy.rect.y + 15
enemy.Direction = "right"
if enemy.rect.x > 750:
enemy.rect.y = enemy.rect.y + 15
enemy.Direction = "left"
loop =+1
for enemy in (allEnemies.sprites()):
enemy.move_enemy()
#draw enemies
allEnemies.draw(gameDisplay)
我从程序中删去了无关的代码，以使您更容易理解。我不太确定为什么要这样做，但我只是想让敌人的班级在如图所示的行中移动，但是旁边会出现一个额外的精灵。
最佳答案
多余的敌人是由辛格尔敌人造成的，该敌人在被主动化时会添加到组中：
a_enemies = Enemy(50,50,"right",1)
allEnemies.add(a_enemies)
删除该代码，以解决该问题。
