继续编写魂斗罗
在上次的博客学习 Python 之 Pygame 开发魂斗罗（十一）中，我们实现了敌人击中玩家碰到玩家，玩家死亡的效果，但是还有一点问题，这次我们来解决一下，之后加入一下地图碰撞体，调整一下整体代码，为加入新的敌人做准备
下面是图片的素材

1. 修改玩家扣减生命值
下面是玩家碰到敌人子弹的函数，我们看到玩家生命值减少是修改变量的值
我们对代码进行修改，把玩家扣减生命值的代码写成函数的形式
在玩家类中新增函数
def damage(self, damage):
if not self.isInvincible:
self.life -= damage
return True
return False
再添加成员变量
self.isInvincible = True
self.isInvincible变量用来让玩家有无敌时间，当玩家复活后，没有落地之前，应该是无敌的，这样防止玩家刚复活就被子弹击中死亡了
damage函数用来扣减玩家生命值，返回值表示是否扣减成功
我们来到主类，把damage()函数调用一下
进入updatePlayerPosition()函数，找到下方红框中的位置
修改代码
# 与敌人碰撞
if pygame.sprite.spritecollideany(MainGame.player1, MainGame.enemyGroup):
if MainGame.player1.damage(1):
MainGame.explodeList.append(Explode(MainGame.player1, ExplodeVariety.PLAYER1))
initPlayer1(MainGame.player1.life)
然后来到子弹类，修改collidePlayer()函数
def collidePlayer(self, player, explodeList):
# 函数的返回值用来表示是否要重新初始化玩家
# 如果当前子弹和玩家发生碰撞
if pygame.sprite.collide_rect(self, player):
if player.damage(1):
self.isDestroy = True
explodeList.append(Explode(player, ExplodeVariety.PLAYER1))
return True
return False
刚才我们设置了isInvincible变量，此时运行游戏，玩家一定是无敌的，因为isInvincible初始值是True，我们让玩家一落地变成不是无敌的
进入updatePlayerPosition()函数，增加下面的代码
if MainGame.player1.isInvincible:
# 玩家落地不无敌
MainGame.player1.isInvincible = False
好了，我们就修改完成了，运行一下，看看有没有问题
运行成功，没有问题
2. 解决玩家下蹲子弹不会击中玩家而是直接让玩家死亡的问题
当我们蹲下时，子弹不会从玩家上面飞过，而是判断为玩家被击中
这个原因是因为玩家的图片很大，判定碰撞的时候要进行判断，如果玩家是蹲下的情况，要计算子弹是否进入了玩家中心以下的范围
我们来到子弹类，对colliderPlayer函数修改
def collidePlayer(self, player, explodeList):
if pygame.sprite.collide_rect(self, player):
# 蹲下的时候，由于图片上半部分是空白，所有子弹必须击中下半部分，才判断为玩家被击中
if player.isDown or player.isSquating:
x = player.rect.x
y = player.rect.y + player.rect.height / 2 + 5
if (x < self.rect.x < player.rect.x + player.rect.width) and (y < self.rect.y < player.rect.y + player.rect.height):
if player.damage(1):
self.isDestroy = True
explodeList.append(Explode(player, ExplodeVariety.PLAYER1))
return True
elif player.isInWater:
x = player.rect.x
y = player.rect.y + player.rect.height / 2
if (x < self.rect.x < player.rect.x + player.rect.width) and (
y < self.rect.y < player.rect.y + player.rect.height):
if player.damage(1):
self.isDestroy = True
explodeList.append(Explode(player, ExplodeVariety.PLAYER1))
return True
else:
if player.damage(1):
self.isDestroy = True
explodeList.append(Explode(player, ExplodeVariety.PLAYER1))
return True
return False
现在我们再运行一下，看看效果
我们看到玩家蹲下时，子弹会从玩家上面过去了
3. 完善地图
接下来，我们把地图碰撞体完善一下，修改主类函数initLand()
def initLand():
land1 = Collider(81, 119 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)
# land1 = Collider(81, 119 * MAP_SCALE, 8000 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)

MainGame.enemyLandGroup = pygame.sprite.Group(eland1, eland8, eland9, eland10)
MainGame.playerColliderGroup.add(MainGame.playerLandGroup)
MainGame.enemyColliderGroup.add(MainGame.enemyLandGroup)
这张图是碰撞体图
我们现在再来运行一下
我们可以看到，现在地图后面都有陆地碰撞体，一直持续到boss那里
4. 增加产生敌人函数，解决一直产生敌人的问题
在现在的代码中，我们产生敌人的逻辑直接写在了update()函数里，为了方便管理，我们把代码提出来写成函数
把上面红框圈出的代码，提出来写成函数
但是，我们之前已经定义过generateEnemy()函数了
我们把原来的generateEnemy()函数改名为generateEnemy1()，表示创建的是敌人1，并且把它变为全局函数
generateEnemy()表示创建的是全部敌人
def generateEnemy1(self, x, y, direction, currentTime):
# 根据玩家的当前位置和方向产生一个敌人
enemy = Enemy1(x, y, direction, currentTime)
# 分别加入敌人列表，所有角色组，敌人碰撞组
MainGame.enemyList.append(enemy)
MainGame.allSprites.add(enemy)
MainGame.enemyGroup.add(enemy)
之后添加成员变量
self.enemyBoolList = [True for _ in range(5)]
这个数组用来指定敌人产生个数的，这里写的5，表示有五个位置产生敌人
那么为什么要有这个数组呢
在原来的产生敌人代码中
if -1505 < self.backRect.x < -1500:
generateEnemy1(MainGame.player1.rect.x + 600, POSITION_1, Direction.LEFT, pygame.time.get_ticks())
generateEnemy1(MainGame.player1.rect.x - 360, POSITION_1, Direction.RIGHT, pygame.time.get_ticks())
我们可以看到，当玩家进入了这个范围（实际是地图移动到了这个范围），就会产生敌人，但是如果移动到这个范围后，玩家停止移动了，那么就会一直产生敌人，这显然不是我们想看到的，我们想的是玩家走到范围内，就产生敌人，代码只执行一次，但是按照原来的逻辑，如果玩家一直站在范围里面，代码就会一直执行，所以我们得设置一个enemyBoolList，如果是True，就执行代码，否则就不执行
修改后的产生敌人的代码如下：
这里就设置了只执行一次产生敌人的代码，列表的长度表示敌人产生点的个数
def generateEnemy(self):
if -1505 < self.backRect.x < -1500:
if self.enemyBoolList[0]:
self.enemyBoolList[0] = False
generateEnemy1(MainGame.player1.rect.x + 600, POSITION_1, Direction.LEFT, pygame.time.get_ticks())
generateEnemy1(MainGame.player1.rect.x - 360, POSITION_1, Direction.RIGHT, pygame.time.get_ticks())
if -1705 < self.backRect.x < -1700:
if self.enemyBoolList[1]:
self.enemyBoolList[1] = False
generateEnemy1(MainGame.player1.rect.x - 360, POSITION_1, Direction.RIGHT, pygame.time.get_ticks())
generateEnemy1(MainGame.player1.rect.x - 400, POSITION_1, Direction.RIGHT,
pygame.time.get_ticks())
我们运行一下游戏，看看有没有问题
ok，一切正常
5. 给玩家类增加计算玩家中心的方法
敌人2发射的子弹带有追踪效果，因此我们要时刻计算玩家的中心
我们给玩家类加入代码
def getCenter(self):
return self.rect.x + self.rect.width / 2, self.rect.y + self.rect.height / 2 + y0
这个代码是计算玩家中心位置的
y0是中心的偏移量，我们在Constants.py中设置
至此，就完啦，接下来就是创建敌人2了
