坦克大战添加音效

我的素材放到了百度网盘里，里面还有原版坦克大战素材，我都放在一起来，我的素材是从原版改的，各位小伙伴可以直接用或者自己改一下再用，做出适合自己的素材

那我们就继续编写坦克大战吧

1. 初始化音效

现在已经完成了敌方坦克和我方坦克的对打了，我们把音效加入一下

创建音乐类

import pygame


class Sound:
    def __init__(self, filename):
        self.filename = filename
        pygame.mixer.init()
        self.sound = pygame.mixer.Sound(self.filename)

    def play(self, loops = 0):
        self.sound.play(loops)

    def stop(self):
        self.sound.stop()

    def setVolume(self):
        self.sound.set_volume(0.2)
        return self

这些代码在 学习 Python 之 Pygame 开发坦克大战（一）中已经提前见过了

2. 加入游戏开始音效和坦克移动音效

坦克的移动是有音效的，在主类加入类成员

playerTankMoveSound = Sound('../Sound/player.move.wav').setVolume()
startingSound = Sound('../Sound/intro.wav')

class MainGame:

    ...
    
    # 坦克移动音效
    playerTankMoveSound = Sound('../Sound/player.move.wav').setVolume()

	# 游戏开始音效
    startingSound = Sound('../Sound/intro.wav')
    
	...

在主函数中调用播放

def startGame(self):
    # 初始化展示模块
    pygame.display.init()
    # 设置窗口大小
    size = (SCREEN_WIDTH, SCREEN_HEIGHT)
    # 初始化窗口
    MainGame.window = pygame.display.set_mode(size)
    # 设置窗口标题
    pygame.display.set_caption('Tank Battle')

    # 初始化我方坦克
    MainGame.playerTank = PlayerTank(PLAYER_TANK_POSITION[0], PLAYER_TANK_POSITION[1], 1, 1)
    
    # 播放开始音乐
    MainGame.startingSound.play()

	...

修改getPlayingModeEvent()函数

def getPlayingModeEvent(self):
    # 获取所有事件
    eventList = pygame.event.get()
    for event in eventList:

        if event.type == pygame.QUIT:
            sys.exit()

        """
        stop属性用来控制坦克移动，当键盘按键按下时，坦克可以移动，一直按住一直移动，当按键抬起时，停止移动
        如果没有该属性，按一下按键移动一次，按一下移动一下，不能一直按住一直移动
        """
        if event.type == pygame.KEYDOWN:
            MainGame.playerTankMoveSound.play(-1)
            if event.key == pygame.K_w:
                MainGame.playerTank.direction = 'UP'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_s:
                MainGame.playerTank.direction = 'DOWN'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_a:
                MainGame.playerTank.direction = 'LEFT'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_d:
                MainGame.playerTank.direction = 'RIGHT'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_j:
                # 判断子弹数量是否超过指定的个数
                if len(MainGame.playerBulletList) < MainGame.playerBulletNumber:
                    bullet = MainGame.playerTank.shot()
                    MainGame.playerBulletList.append(bullet)

        if event.type == pygame.KEYUP:
            MainGame.playerTankMoveSound.stop()
            if event.key == pygame.K_w:
                MainGame.playerTank.stop = True
            elif event.key == pygame.K_s:
                MainGame.playerTank.stop = True
            elif event.key == pygame.K_a:
                MainGame.playerTank.stop = True
            elif event.key == pygame.K_d:
                MainGame.playerTank.stop = True

            else:
                e.draw(MainGame.window)

if __name__ == '__main__':
    MainGame().startGame()

3. 添加坦克开火音效

玩家坦克发射子弹是有音效的

修改getPlayingModeEvent()函数

def getPlayingModeEvent(self):
    # 获取所有事件
    eventList = pygame.event.get()
    for event in eventList:

        if event.type == pygame.QUIT:
            sys.exit()

        """
        stop属性用来控制坦克移动，当键盘按键按下时，坦克可以移动，一直按住一直移动，当按键抬起时，停止移动
        如果没有该属性，按一下按键移动一次，按一下移动一下，不能一直按住一直移动
        """
        if event.type == pygame.KEYDOWN:
            MainGame.playerTankMoveSound.play(-1)
            if event.key == pygame.K_w:
                MainGame.playerTank.direction = 'UP'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_s:
                MainGame.playerTank.direction = 'DOWN'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_a:
                MainGame.playerTank.direction = 'LEFT'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_d:
                MainGame.playerTank.direction = 'RIGHT'
                MainGame.playerTank.stop = False
            elif event.key == pygame.K_j:
                # 判断子弹数量是否超过指定的个数
                if len(MainGame.playerBulletList) < MainGame.playerBulletNumber:
                    bullet = MainGame.playerTank.shot()
                    MainGame.playerBulletList.append(bullet)
                    # 添加音效
                    Sound('../Sound/shoot.wav').play(0)

4. 添加装甲削减音效

当我方坦克击中时，如果有装甲，装甲较少时会有音效
当敌方坦克血量减少时，也会出现音效

修改子弹类中的playerBulletCollideEnemyTank()函数，增加敌方坦克血量减少音效

def playerBulletCollideEnemyTank(self, enemyTankList, explodeList):
    # 循环遍历坦克列表，检查是否发生了碰撞
    for tank in enemyTankList:
        if pygame.sprite.collide_rect(tank, self):
            tank.loseLife(self.damage)
            # 把子弹设置为销毁状态
            self.isDestroy = True
            if tank.life == 0:
                # 增加爆炸效果
                explode = Explode(tank, 50)
                explodeList.append(explode)
            else:
                Sound('../Sound/enemy.armor.hit.wav').play()

修改子弹类中的enemyBulletCollidePlayerTank()函数，增加我方坦克血量装甲音效

def enemyBulletCollidePlayerTank(self, playerTank, explodeList):
# 玩家坦克生命值为0，不用检测
if playerTank.life <= 0:
    return
# 检测是否发生碰撞
if pygame.sprite.collide_rect(playerTank, self):
    # 发生碰撞先减少护甲，护甲为0时扣减生命值
    if playerTank.armor > 0:
        playerTank.armor -= self.damage
        playerTank.armor = max(0, playerTank.armor)
        Sound('../Sound/enemy.armor.hit.wav').play()
    else:
        playerTank.loseLife(self.damage)
        # 增加爆炸效果
        explode = Explode(playerTank, 50)
        explodeList.append(explode)
        playerTank.life = max(0, playerTank.life)
        if playerTank.life != 0:
            playerTank.isResurrecting = True
    # 让子弹销毁
    self.isDestroy = True

5. 添加坦克爆炸音效

修改子弹类中的下面两个函数

def playerBulletCollideEnemyTank(self, enemyTankList, explodeList):
    # 循环遍历坦克列表，检查是否发生了碰撞
    for tank in enemyTankList:
        if pygame.sprite.collide_rect(tank, self):
            tank.loseLife(self.damage)
            # 把子弹设置为销毁状态
            self.isDestroy = True
            if tank.life == 0:
                # 增加爆炸效果
                explode = Explode(tank, 50)
                explodeList.append(explode)
                Sound('../Sound/kill.wav').play()
            else:
                Sound('../Sound/enemy.armor.hit.wav').play()

def enemyBulletCollidePlayerTank(self, playerTank, explodeList):
    # 玩家坦克生命值为0，不用检测
    if playerTank.life <= 0:
        return
    # 检测是否发生碰撞
    if pygame.sprite.collide_rect(playerTank, self):
        # 发生碰撞先减少护甲，护甲为0时扣减生命值
        if playerTank.armor > 0:
            playerTank.armor -= self.damage
            playerTank.armor = max(0, playerTank.armor)
            Sound('../Sound/enemy.armor.hit.wav').play()
        else:
            playerTank.loseLife(self.damage)
            # 增加爆炸效果
            explode = Explode(playerTank, 50)
            explodeList.append(explode)
            playerTank.life = max(0, playerTank.life)
            Sound('../Sound/kill.wav').play()
            if playerTank.life != 学习 Python 之 Pygame 开发坦克大战
