那我们就继续编写坦克大战吧

1. 创建砖墙

坦克大战中，砖墙是最常见的墙，子弹都可以轻松击穿，下面我们来加入到自己的坦克大战中

创建砖墙类

import pygame.image
from ParentObject import ParentObject

class BrickWall(ParentObject):
    def __init__(self, x, y):
        super().__init__()
        self.image = pygame.image.load('../Image/Wall/BrickWall.png')
        self.rect = self.image.get_rect()
        self.rect.left = x
        self.rect.top = y
        self.isDestroy = False

    def draw(self, window):
        window.blit(self.image, self.rect)

在主类中加入砖墙列表

class MainGame:
    ...
    # 砖墙
    brickWallList = []
    ...

在主类中加入初始化砖墙函数和显示砖墙函数

def drawBrickWall(self, brickWallList):
    for brickWall in brickWallList:
        if brickWall.isDestroy:
            brickWallList.remove(brickWall)
        else:
            brickWall.draw(MainGame.window)

def initBrickWall(self):
    for i in range(20):
        MainGame.brickWallList.append(BrickWall(i * 25, 200))

这里我在y = 200的位置，连续画出20个砖，砖的图片是25x25的，所以为了防止重叠，要间隔25个距离（像素）

在主函数startGame()函数中调用函数

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()
    
    # 初始化场景
    self.initBrickWall()

    while 1:
        # 设置背景颜色
        MainGame.window.fill(BACKGROUND_COLOR)

        # 获取窗口事件
        self.getPlayingModeEvent()
        
        # 显示物体
        self.drawBrickWall(MainGame.brickWallList)

        # 展示敌方坦克
        self.drawEnemyTank()

        # 显示我方坦克
        MainGame.playerTank.draw(MainGame.window, PLAYER_TANK_POSITION[0], PLAYER_TANK_POSITION[1])

        # 我方坦克移动
        if not MainGame.playerTank.stop:
            MainGame.playerTank.move()
            MainGame.playerTank.collideEnemyTank(MainGame.enemyTankList)

        # 显示我方坦克子弹
        self.drawPlayerBullet(MainGame.playerBulletList)

        # 展示敌方坦克子弹
        self.drawEnemyBullet()

        # 展示爆炸效果
        self.drawExplode()

        # 更新窗口
        pygame.display.update()

运行一下，看看结果

但是墙只是摆设，子弹可以穿过，坦克也可以穿过，下面给墙增加碰撞效果

2. 给砖墙增加子弹击中的碰撞效果

在子弹类中增加函数

def bulletCollideBrickWall(self, brickWallList, explodeList):
    for brickWall in brickWallList:
        # 子弹与墙发生碰撞
        if pygame.sprite.collide_rect(self, brickWall):
            self.isDestroy = True
            brickWall.isDestroy = True
            # 碰撞出现爆炸效果
            explode = Explode(brickWall, 25)
            explodeList.append(explode)
            # 出现爆炸播放音效
            Sound('../Sound/block.wav').play()

在主函数中调用
修改显示子弹的两个函数

def drawPlayerBullet(self, playerBulletList):
    # 遍历整个子弹列表，如果是没有被销毁的状态，就把子弹显示出来，否则从列表中删除
    for bullet in playerBulletList:
        if not bullet.isDestroy:
            bullet.draw(MainGame.window)
            bullet.move(MainGame.explodeList)
            bullet.playerBulletCollideEnemyTank(MainGame.enemyTankList, MainGame.explodeList)
            bullet.bulletCollideBrickWall(MainGame.brickWallList, MainGame.explodeList)
        else:
            playerBulletList.remove(bullet)

def drawEnemyBullet(self):
    for bullet in MainGame.enemyTankBulletList:
        if not bullet.isDestroy:
            bullet.draw(MainGame.window)
            bullet.move(MainGame.explodeList)
            bullet.enemyBulletCollidePlayerTank(MainGame.playerTank, MainGame.explodeList)
            bullet.bulletCollideBrickWall(MainGame.brickWallList, MainGame.explodeList)
        else:
            bullet.source.bulletCount -= 1
            MainGame.enemyTankBulletList.remove(bullet)

运行一下看看

可以看到墙可以被打掉了

3. 给砖墙添加坦克不能通过的碰撞效果

在敌方坦克类中加入函数，在我方坦克类中加入函数
collideBrickWall()

def collideBrickWall(self, brickWallList):
    for brickWall in brickWallList:
        if pygame.sprite.collide_rect(self, brickWall):
            self.rect.left = self.prvX
            self.rect.top = self.prvY

在主类中调用
在while循环中调用

while 1:
    # 设置背景颜色
    MainGame.window.fill(BACKGROUND_COLOR)

    # 获取窗口事件
    self.getPlayingModeEvent()

    # 显示物体
    self.drawBrickWall(MainGame.brickWallList)

    # 展示敌方坦克
    self.drawEnemyTank()

    # 显示我方坦克
    MainGame.playerTank.draw(MainGame.window, PLAYER_TANK_POSITION[0], PLAYER_TANK_POSITION[1])

    # 我方坦克移动
    if not MainGame.playerTank.stop:
        MainGame.playerTank.move()
        MainGame.playerTank.collideEnemyTank(MainGame.enemyTankList)
        # 不能撞墙
        MainGame.playerTank.collideBrickWall(MainGame.brickWallList)

在主类的drawEnemyTank()中调用

def drawEnemyTank(self):
    ...
    for tank in MainGame.enemyTankList:
        # 坦克还有生命值
        if tank.life > 0:
            tank.draw(MainGame.window)
            tank.move()
            tank.collidePlayerTank(MainGame.playerTank)
            tank.collideEnemyTank(MainGame.enemyTankList)
            # 不能撞墙
            tank.collideBrickWall(MainGame.brickWallList)
            bullet = tank.shot()
            if bullet is not None:
                MainGame.enemyTankBulletList.append(bullet)
        # 坦克生命值为0，就从列表中剔除
        else:
            MainGame.enemyTankCurrentCount -= 1
            MainGame.enemyTankList.remove(tank)

运行一下，看看效果

确实是不能穿过了
那就完成啦，接下来就是添加其他的物体了
添加的过程跟添加砖墙是一样的

4. 添加石墙

创建石墙类

import pygame.image
from ParentObject import ParentObject

class StoneWall(ParentObject):
    def __init__(self, x, y):
        super().__init__()
        self.image = pygame.image.load('../Image/Wall/StoneWall.png')
        self.rect = self.image.get_rect()
        self.rect.left = x
        self.rect.top = y
        self.isDestroy = False

    def draw(self, window):
        window.blit(self.image, self.rect)

在主类中加入石墙列表
在主类中加入显示石墙函数

def initStoneWall(self):
    for i in range(20):
        MainGame.stoneWallList.append(StoneWall(i * 25, 400))
        
def drawStoneWall(self, stoneWallList):
    for stoneWall in stoneWallList:
        if stoneWall.isDestroy:
            stoneWallList.remove(stoneWall)
        else:
            stoneWall.draw(MainGame.window)

给石墙添加坦克不能通过的碰撞效果
在敌方坦克类中加入函数，在我方坦克类中加入函数
collideStoneWall()

def collideStoneWall(self, stoneWallList):
    for stoneWall in stoneWallList:
        if pygame.sprite.collide_rect(self, stoneWall):
            self.rect.left = self.prvX
            self.rect.top = self.prvY

在主类中调用函数

接下来是给子弹添加打击石墙的效果

def bulletCollideStoneWall(self, stoneWallList, explodeList):
    for stoneWall in stoneWallList:
        if pygame.sprite.collide_rect(self, stoneWall):
            # 判断坦克的等级，大于等于2时，可以打穿石墙
            if self.source.level >= 2:
                stoneWall.isDestroy = True
            self.isDestroy = True
            explode = Explode(stoneWall, 25)
            explodeList.append(explode)
            Sound('../Sound/block.wav').play()

在主类中调用函数
