我的敌人AI没有检测到碰撞。我一直在使用用于播放器碰撞检测的代码。我对其进行了调整，以适应敌人，但无法正常工作：
class Enemy(Entity):
def __init__(self, x, y,player):
pygame.sprite.Sprite.__init__(self)
self.image = Surface((32, 32))
self.xvel = 0
self.yvel = 0
self.image.fill(Color("#FF0000")) #Enemy is red
self.onGorund = False
#Enemy is 32 * 32 pixels
self.image.convert()
self.rect = Rect(x, y, 32, 32)
self.counter = 0 #counter variable
self.player = player
def move(self, speed = 5): # chase movement
if self.rect.x > self.player.rect.x: # Movement along x direction
self.rect.x -= speed
elif self.rect.x < self.player.rect.x:
self.rect.x += speed
if self.rect.y < self.player.rect.y: # Movement along y direction
self.rect.y += speed
elif self.rect.y > self.player.rect.y:
self.rect.y -= speed
def collide(self, xvel, yvel, platforms):
for p in platforms:
if pygame.sprite.collide_rect(self, p):
if isinstance(p, Player_class):
pygame.quit()
sys.exit()
if xvel > 0:
self.rect.right = p.rect.left
print ("collide right")
if xvel < 0:
self.rect.left = p.rect.right
print ("collide left")
if yvel > 0:
self.rect.bottom = p.rect.top
self.onGround = True
self.yvel = 0
if yvel < 0:
self.rect.top = p.rect.bottom
def update(self, platforms):
if up:
if self.onGround: self.yvel -= 10 #only jump if player is on the ground
if down:
pass
if running:
self.xvel = 12
if left:
self.xvel = -8
if right:
self.xvel = 8
if not self.onGround:
self.yvel += 0.3 #only accelerate with gravity if in the air
if self.yvel > 100: self.yvel = 100 #terminal velocity = 100
if not(left or right):
self.xvel = 0
self.rect.left += self.xvel #falls or jumps
self.collide(self.xvel, 0, platforms) #creates collisions along the x axis
self.rect.top += self.yvel #creates collisions along the y axis
self.onGround = False; #assumes that the player is in the air
# do y-axis collisions
self.collide(0, self.yvel, platforms)
我一直在试图让敌人碰触玩家时关闭窗口，但问题是，如果敌人不知道它正在碰触玩家，它就无法关闭窗口。请询问是否需要更多代码。
答案 0 :(得分：0)
有些事情需要更改。
在move方法中，您应该设置速度（self.xvel和self.yvel），而不是直接移动矩形。
然后在move方法中调用update方法，移动精灵的矩形并处理碰撞。另外，您需要立即在update函数中调用main方法而不是move并传递platforms列表：
enemy_list.draw(screen)
for e in enemy_list:
e.update(platforms)
在collide方法中，您检查平台之一是否是玩家实例：
for p in platforms:
if pygame.sprite.collide_rect(self, p):
if isinstance(p, Player_class):
pygame.quit()
sys.exit()
但是，玩家精灵不在此列表中，因此不会发生冲突。
敌人实际上是指玩家（self.player），因此您可以执行以下操作来检查他们是否碰撞：
if pygame.sprite.collide_rect(self, self.player):
或：
if self.rect.colliderect(self.player.rect):
这是一个完整的示例（我从您先前的问题中提取了代码，并尝试改进一些其他内容）：
