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 = Trueself.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) land2 =

pygame.sprite.Group( land1, land2, land3, land4, land5, land6, land7, land8, land9, land10, land11, land12, land13, land14, land15, land16, land17, land18, land19, land20, land21, land22, land23, land24, land25, land26, land27, land28, land29, land30, land31, land32, land33, land34, land35, land36, land37, land38, land39 ) eland1 = Collider(81, 119 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE) eland8 = Collider(1120 * RATIO, 215 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE) eland9 = Collider(1650 * RATIO, 119 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE) eland10 = Collider(2185 * RATIO, 119 * MAP_SCALE, 8 * LAND_LENGTH * 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
完整的主类代码

drawPlayerOneBullet(player1BulletList): for bullet in player1BulletList: if bullet.isDestroy: player1BulletList.remove(bullet) else: bullet.draw(MainGame.window) bullet.move() bullet.collideEnemy(MainGame.enemyList, MainGame.explodeList) def enemyUpdate(enemyList, enemyBulletList): # 遍历整个敌人列表 for enemy in enemyList: # 如果敌人已经被摧毁了 if enemy.isDestroy: # 删除它的相关信息 enemyList.remove(enemy) MainGame.allSprites.remove(enemy) MainGame.enemyGroup.remove(enemy) # 否则 else: # 检查位置 enemy.checkPosition(MainGame.player1.rect.x, MainGame.player1.rect.y) # 显示敌人

4 enemy.isFalling = True # 改变下落时的图片 enemy.image = enemy.rightFallImage if enemy.direction == Direction.RIGHT else enemy.leftFallImage else: enemy.isFalling = False # 如果与河发生碰撞，表示敌人落到了水中，那么敌人直接死亡 if
