学习 Python 之 Pygame 开发魂斗罗（十一）
继续编写魂斗罗
在上次的博客学习 Python 之 Pygame 开发魂斗罗（十）中，我们实现了敌人死亡的爆炸效果，这次咱们实现一下玩家被敌人击中或者碰到敌人死亡的效果
下面是图片的素材

1. 改写主类函数中的代码顺序
首先，我们改写一下update()函数中的代码顺序
defupdate(self, window, player1BulletList):# 加载背景
window.blit(self.background, self.backRect)# 敌人更新
enemyUpdate(MainGame.enemyList, MainGame.enemyBulletList)
drawExplode(MainGame.explodeList)
drawPlayerOneBullet(MainGame.player1BulletList)
drawEnemyBullet(MainGame.enemyBulletList)# 更新人物
currentTime = pygame.time.get_ticks()
MainGame.allSprites.update(self.keys, currentTime, player1BulletList)
self.updatePlayerPosition()
updateEnemyPosition()# 摄像机移动
self.camera()# 显示物体
MainGame.allSprites.draw(window)# 加载敌人if-1503< self.backRect.x <-1500:
self.generateEnemy(MainGame.player1.rect.x +600, POSITION_1, Direction.LEFT, pygame.time.get_ticks())
self.generateEnemy(MainGame.player1.rect.x -360, POSITION_1, Direction.RIGHT, pygame.time.get_ticks())if-1703< self.backRect.x <-1700:
self.generateEnemy(MainGame.player1.rect.x -360, POSITION_1, Direction.RIGHT, pygame.time.get_ticks())
self.generateEnemy(MainGame.player1.rect.x -400, POSITION_1, Direction.RIGHT,
pygame.time.get_ticks())for collider in MainGame.playerLandGroup:
r = collider.draw(window, self.player1.rect.y)# 如果没有画出来，表示玩家高度低于直线，所有把直线从组中删除ifnot r:# 删除前先检查一下是不是在组中if collider in MainGame.playerColliderGroup:# 删除并加入栈
MainGame.colliderStack.insert(0, collider)
MainGame.playerColliderGroup.remove(collider)else:# 如果画出来了，判断一下玩家距离是否高于线的距离if collider.rect.y > self.player1.rect.bottom:# 如果是的话，且冲突栈不为空，那么从栈中取出一个元素放入冲突组，最前面的元素一定是先如队列的iflen(MainGame.colliderStack)>0:
f = MainGame.colliderStack.pop()
MainGame.playerColliderGroup.add(f)
MainGame.playerRiverGroup.draw(window)
其次，把camera()函数中的下面框出的代码，提出来写成一个函数
defmapObjectMove(self):for sprite in MainGame.allSprites:
sprite.rect.x -= self.cameraAdaption
for collider in MainGame.playerColliderGroup:
collider.rect.x -= self.cameraAdaption
for collider in MainGame.colliderStack:
collider.rect.x -= self.cameraAdaption
for collider in MainGame.enemyColliderGroup:
collider.rect.x -= self.cameraAdaption
最后，我们把加载背景图片的代码也单独写成一个函数
先找到加载背景图片代码的地方，在主类的构造函数里
把红框圈出的代码提出来，写成一个函数，并且调用
definitBackground(self):# 读取背景图片
self.background = pygame.image.load('../Image/Map/1/Background/First(No Bridge).png')
self.backRect = self.background.get_rect()
self.background = pygame.transform.scale(
self.background,(int(self.backRect.width * MAP_SCALE),int(self.backRect.height * MAP_SCALE)))
self.backRect.x =-1280
把使用到的两个成员变量在构造函数中创建一下
好，现在运行一下游戏，看看有没有问题
运行后发现，一切正常
2. 修改玩家初始化
现在我们给玩家加入生命值，当玩家生命值为0时，游戏结束
首先，在玩家类中的构造函数里，增加一个参数
用来指定玩家初始的生命值
其次，在玩家类的构造函数中加入一个成员变量
之后，在主类中，加入一个全局函数，用来初始化玩家
definitPlayer1(life):if life ==0:pass
MainGame.allSprites.remove(MainGame.player1)
MainGame.player1 = PlayerOne(pygame.time.get_ticks(), life)
MainGame.player1.rect.x =80
MainGame.player1.rect.bottom =0# 把角色放入组中，方便统一管理
MainGame.allSprites.add(MainGame.player1)
这个函数的作用是：先把之前的玩家从组中删除，之后再创建一个新的玩家，新的玩家的生命值比上次的减少1，如果生命值为0，那么就游戏结束，现在先不着急写出游戏结束的函数
最后，把原来的玩家初始化代码改成调用这个函数
运行一下游戏，看看有没有问题
出现了问题
分析一下原因：第一次调用这个函数的时候，allSprites是None，如下图
我们把None改一下
这样就可以啦，再运行一下游戏，看看还有没有问题
这次就没有问题啦
3. 显示玩家生命值
在原版的魂斗罗中，玩家的生命值在左上角显示，我们来实现一下
首先，在构造函数中把生命值的图片加载进来
# 显示玩家生命值
self.lifeImage = loadImage('../Image/Player/Player1/Life/life.png')
在主类中加入成员函数
defdrawLifeImage(self, window):# 如果玩家的生命值大于3，那么生命值图标就显示3个if MainGame.player1.life >3:
number =3# 否则，有几个显示几个，肯定不超过三个else:
number = MainGame.player1.life
rect = self.lifeImage.get_rect()# 设置生命值图标的显示位置
rect.y =5for i inrange(number):# 每个图标之间的距离为25像素
rect.x =5+ i *20
window.blit(self.lifeImage, rect)
之后我们调用一下这个函数，在update()中调用
好，现在运行一下游戏，看看效果
可以看到，左上角就显示玩家生命值啦
不过现在敌人的子弹击中我们，还有敌人碰到我们，我们都不会死亡，接下来我们来实现一下
4. 设置玩家碰到敌人死亡
我们找到主类中的updatePlayerPosition()函数，在其中加入下面这段代码
# 与敌人碰撞if pygame.sprite.spritecollideany(MainGame.player1, MainGame.enemyGroup):
MainGame.player1.life -=1
initPlayer1(MainGame.player1.life)
这段代码就是检测玩家和敌人是否发生碰撞，如果发生了，玩家生命值减少1，重新初始化玩家
defupdatePlayerPosition(self):# 在index的循环次数中，不进行碰撞检测，用来让玩家向下跳跃if self.index >0:
self.index -=1
self.player1.rect.x += self.player1.xSpeed
self.player1.rect.y += self.player1.ySpeed
self.player1.isDown =Falseelse:# 首先更新y的位置
self.player1.rect.y += self.player1.ySpeed
# 玩家向下跳跃，35次循环内不进行碰撞检测if self.player1.state == State.JUMP and self.player1.isDown:
self.index =35# 玩家向上跳跃，15次循环内不进行碰撞检测elif self.player1.state == State.JUMP and self.player1.isUp:
self.index =15else:# 检测碰撞# 这里是玩家和所有碰撞组中的碰撞体检测碰撞，如果发生了碰撞，就会返回碰撞到的碰撞体对象
collider = pygame.sprite.spritecollideany(self.player1, MainGame.playerColliderGroup)# 如果发生碰撞，判断是不是在河里if collider in MainGame.playerRiverGroup:# 在河里设置isInWater
self.player1.isInWater =True# 设置玩家在河里不能跳跃
self.player1.isJumping =False# 默认落下去是站在河里的
self.player1.isStanding =True# 玩家方向不能向下
self.player1.isDown =False# 根据玩家方向，加载落入河中的一瞬间的图片if self.player1.direction == Direction.RIGHT:
self.player1.image = self.player1.rightInWaterImage
else:
self.player1.image = self.player1.leftInWaterImage
# 判断是不是在陆地上elif collider in MainGame.playerLandGroup:
self.player1.isInWater =False# 如果发生碰撞if collider:# 判断一下人物的y速度，如果大于0，则说明玩家已经接触到了碰撞体表面，需要让玩家站在表面，不掉下去if self.player1.ySpeed >0:
self.player1.ySpeed =0
self.player1.state = State.WALK
self.player1.rect.bottom = collider.rect.top
else:# 否则的话，我们创建一个玩家的复制
tempPlayer = copy.copy(self.player1)# 让玩家的纵坐标—+1，看看有没有发生碰撞
tempPlayer.rect.y +=1# 如果没有发生碰撞，就说明玩家下面不是碰撞体，是空的ifnot pygame.sprite.spritecollideany(tempPlayer, MainGame.playerColliderGroup):# 如果此时不是跳跃状态，那么就让玩家变成下落状态，因为玩家在跳跃时，是向上跳跃，不需要对下面的物体进行碰撞检测if tempPlayer.state != State.JUMP:
self.player1.state = State.FALL
tempPlayer.rect.y -=1# 与敌人碰撞if pygame.sprite.spritecollideany(MainGame.player1, MainGame.enemyGroup):
MainGame.player1.life -=1
initPlayer1(MainGame.player1.life)# 更新x的位置
self.player1.rect.x += self.player1.xSpeed
# 同样的检查碰撞
collider = pygame.sprite.spritecollideany(self.player1, MainGame.playerColliderGroup)# 如果发生了碰撞if collider:# 判断玩家的x方向速度，如果大于0，表示右边有碰撞体if self.player1.xSpeed >0:# 设置玩家的右边等于碰撞体的左边
self.player1.rect.right = collider.rect.left
else:# 左边有碰撞体
self.player1.rect.left = collider.rect.right
self.player1.xSpeed =0
tempPlayer = copy.copy(self.player1)
tempPlayer.rect.y +=1if c := pygame.sprite.spritecollideany(tempPlayer, MainGame.playerColliderGroup):if c in MainGame.playerLandGroup:
self.player1.isInWater =Falseelif c in MainGame.playerRiverGroup:
self.player1.isInWater =True
tempPlayer.rect.y -=1
好，现在运行一下游戏，看看效果
可以看到，玩家碰到敌人后就直接重新复活了，并且生命值减少了1
不过现在并没有实现敌人子弹击中玩家，玩家死亡，下面我们来实现
5. 设置敌人子弹击中玩家
首先，玩家死亡时，会有死亡的图片，我们要加入进去
修改Constants.py代码，加入爆炸种类
classExplodeVariety(Enum):
CIRCLE =1
BRIDGE =2
PLAYER1 =3
其次，在爆炸类中根据爆炸种类加载不同的图片
图片素材我已经更新了，在网盘里就可以下载到
完整的爆炸效果类代码
classExplode:def__init__(self,object, variety = ExplodeVariety.CIRCLE, isUseTime =False):# 获取爆炸对象的位置
self.rect =object.rect
if variety == ExplodeVariety.CIRCLE:
self.images =[
loadImage('../Image/Explode/circleExplode1.png'),
loadImage('../Image/Explode/circleExplode1.png'),
loadImage('../Image/Explode/circleExplode1.png'),
loadImage('../Image/Explode/circleExplode1.png'),
loadImage('../Image/Explode/circleExplode2.png'),
loadImage('../Image/Explode/circleExplode2.png'),
loadImage('../Image/Explode/circleExplode2.png'),
loadImage('../Image/Explode/circleExplode2.png'),
loadImage('../Image/Explode/circleExplode3.png'),
loadImage('../Image/Explode/circleExplode3.png'),
loadImage('../Image/Explode/circleExplode3.png'),
loadImage('../Image/Explode/circleExplode3.png'),]elif variety == ExplodeVariety.BRIDGE:
self.images =[
loadImage('../Image/Explode/bridgeExplode1.png'),
loadImage('../Image/Explode/bridgeExplode2.png'),
loadImage('../Image/Explode/bridgeExplode3.png'),]elif variety == ExplodeVariety.PLAYER1:
self.images =[
loadImage('../Image/Player/Player1/Death/death.png'),
loadImage('../Image/Player/Player1/Death/death.png'),
loadImage('../Image/Player/Player1/Death/death.png'),
loadImage('../Image/Player/Player1/Death/death.png'),
loadImage('../Image/Player/Player1/Death/death.png'),]
self.index =0
self.image = self.images[self.index]
self.isDestroy =False
self.isUseTime = isUseTime
self.lastTime =Nonedefdraw(self, window, currentTime =None):if self.isUseTime:if currentTime - self.lastTime >115:# 根据索引获取爆炸对象, 添加到主窗口# 让图像加载五次，这里可以换成五张大小不一样的爆炸图片，可以实现让爆炸效果从小变大的效果if self.index <len(self.images):
self.image = self.images[self.index]
self.index +=1
window.blit(self.image, self.rect)else:
self.isDestroy =True
self.index =0
self.lastTime = currentTime
else:
window.blit(self.image, self.rect)else:# 根据索引获取爆炸对象, 添加到主窗口# 让图像加载五次，这里可以换成五张大小不一样的爆炸图片，可以实现让爆炸效果从小变大的效果if self.index <len(self.images):
self.image = self.images[self.index]
self.index +=1
window.blit(self.image, self.rect)else:
self.isDestroy =True
self.index =0
最后，我们就可以在子弹类中加入代码，让子弹击中玩家时，玩家死亡
defcollidePlayer(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):
self.isDestroy =True# 玩家生命值减少1
player.life -=1# 加入玩家的死亡效果
explodeList.append(Explode(player, ExplodeVariety.PLAYER1))# 返回TruereturnTruereturnFalse
函数的返回值用来表示是否要重新初始化玩家
接下来，在主类中调用这个函数，找到drawEnemyBullet()函数，在其中加入代码
之前敌人碰到玩家，玩家死亡，但是没有显示玩家死亡的图片，这里我们加入以下
来到updatePlayerPosition()函数，加入代码
好，下面我们运行一下，看看效果
可以看到子弹击中玩家后，玩家就出现死亡效果啦
但是目前玩家会无限复活，即使左上角的生命值没了，也会复活，这是因为玩家生命值归0后的代码我们并没有写，所以会出现这样的情况，后面我们再加上
6. 修改updatePlayerPosition()函数逻辑
接下来，我们把主类中的有些代码提出来，单独形成新的函数
来到updatePlayerPosition()函数，把下面框出的代码提出来，形成新的函数
defriverCollide(self):# 在河里设置isInWater
self.player1.isInWater =True# 设置玩家在河里不能跳跃
self.player1.isJumping =False# 默认落下去是站在河里的
self.player1.isStanding =True# 玩家方向不能向下
self.player1.isDown =False# 根据玩家方向，加载落入河中的一瞬间的图片if self.player1.direction == Direction.RIGHT:
self.player1.image = self.player1.rightInWaterImage
else:
self.player1.image = self.player1.leftInWaterImage
原来的代码修改一下
运行一下游戏，看看有没有什么问题
并没有发现什么问题
