学习 Python 之 Pygame 开发魂斗罗十二继续编写魂斗罗1. 修改玩家扣减生命值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3. 完善地图4. 增加产生敌人函数解决一直产生敌人的问题5. 给玩家类增加计算玩家中心的方法继续编写魂斗罗
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 - damagereturn Truereturn 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 TrueexplodeList.append(Explode(player, ExplodeVariety.PLAYER1))return Truereturn 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.xy player.rect.y player.rect.height / 2 5if (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 TrueexplodeList.append(Explode(player, ExplodeVariety.PLAYER1))return Trueelif player.isInWater:x player.rect.xy player.rect.y player.rect.height / 2if (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 TrueexplodeList.append(Explode(player, ExplodeVariety.PLAYER1))return Trueelse:if player.damage(1):self.isDestroy TrueexplodeList.append(Explode(player, ExplodeVariety.PLAYER1))return Truereturn 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 Collider(400, 151 * MAP_SCALE, 96 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land3 Collider(640, 183 * MAP_SCALE, 33 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land4 Collider(880, 183 * MAP_SCALE, 33 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land5 Collider(720, 215 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land6 Collider(1040, 154 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land7 Collider(1600, 166 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land8 Collider(1120 * RATIO, 215 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land9 Collider(1650 * RATIO, 119 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land10 Collider(2185 * RATIO, 119 * MAP_SCALE, 8 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land11 Collider(2595 * RATIO, 215 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land12 Collider(2770 * RATIO, 167 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land13 Collider(2535 * RATIO, 87 * MAP_SCALE, 16 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land14 Collider(2950 * RATIO, 151 * MAP_SCALE, 7 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land15 Collider(3185 * RATIO, 215 * MAP_SCALE, 6 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land16 Collider(3420 * RATIO, 119 * MAP_SCALE, 7 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land17 Collider(3537 * RATIO, 183 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land18 Collider(3715 * RATIO, 183 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land19 Collider(3890 * RATIO, 167 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land20 Collider(3775 * RATIO, 87 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land21 Collider(4010 * RATIO, 151 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land22 Collider(4125 * RATIO, 119 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land23 Collider(4304 * RATIO, 151 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land24 Collider(4304 * RATIO, 216 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land25 Collider(4361 * RATIO, 183 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land26 Collider(4537 * RATIO, 119 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land27 Collider(4598 * RATIO, 87 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land28 Collider(4657 * RATIO, 167 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land29 Collider(4598 * RATIO, 216 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land30 Collider(4776 * RATIO, 119 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land31 Collider(4835 * RATIO, 151 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land32 Collider(5010 * RATIO, 216 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land33 Collider(5250 * RATIO, 183 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land34 Collider(5423 * RATIO, 151 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land35 Collider(5543 * RATIO, 119 * MAP_SCALE, 4 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land36 Collider(5601 * RATIO, 167 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land37 Collider(5541 * RATIO, 216 * MAP_SCALE, 8 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land38 Collider(5776 * RATIO, 151 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land39 Collider(5836 * RATIO, 183 * MAP_SCALE, 1 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)MainGame.playerLandGroup 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] FalsegenerateEnemy1(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] FalsegenerateEnemy1(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
