那我们就继续编写坦克大战吧

1. 实现敌方坦克与我方坦克间的碰撞

由于已经完成了屏幕中出现敌方和我方坦克,现在的问题就是如果我方坦克碰到了敌方坦克,应该是走不动的,即不能穿模

在敌方坦克类和我方坦克类中加入两个属性,用来记录上一次的位置,如果是你用的是继承,那么在父类加入

# 碰撞前的坐标
self.prvX = self.rect.left
self.prvY = self.rect.top

修改我方坦克类move()函数

def move(self):
    if self.accumulation >= 1:
        self.accumulation = 0
        # 记录上一次的位置
        self.prvX = self.rect.left
        self.prvY = self.rect.top
        if self.direction == 'LEFT':
            if self.rect.left > 0:
                self.rect.left -= self.speed
        elif self.direction == 'UP':
            if self.rect.top > 0:
                self.rect.top -= self.speed
        elif self.direction == 'DOWN':
            if self.rect.top < 555:
                self.rect.top += self.speed
        elif self.direction == 'RIGHT':
            if self.rect.left < 855:
                self.rect.left += self.speed
    else:
        self.accumulation += 0.20

修改敌方坦克类move()函数

def move(self):
    """
    新增步数变量, 当坦克移动时, 步数进行减少, 当步数小于等于0的时候, 修改地方坦克的方向
    :return: None
    """
    if self.stop:
        if self.step <= 0:
            self.direction = self.randDirection()
            self.step = 30
        else:
            if self.accumulationMax >= 1:
                self.accumulationMax = 0
                # 记录上一次的位置
                self.prvX = self.rect.left
                self.prvY = self.rect.top
                if self.direction == 'LEFT':
                    if self.rect.left > 0:
                        self.rect.left -= self.speed
                elif self.direction == 'UP':
                    if self.rect.top > 0:
                        self.rect.top -= self.speed
                elif self.direction == 'DOWN':
                    if self.rect.top < 555:
                        self.rect.top += self.speed
                elif self.direction == 'RIGHT':
                    if self.rect.left < 855:
                        self.rect.left += self.speed
                self.step -= 1
            else:
                self.accumulationMax += self.accumulation

加入碰撞检测函数
在两个类中都加入

pygame.sprite.collide_rect()函数用来检测物体碰撞,该物体必须继承pygame.sprite.Sprite类

def collideEnemyTank(self, enemyTankList):
    # 遍历全部敌方坦克,检查有没有碰撞
    for enemyTank in enemyTankList:
        if pygame.sprite.collide_rect(self, enemyTank):
            # 如果碰撞了,就保持原来的位置
            self.rect.left = self.prvX
            self.rect.top = self.prvY
def collidePlayerTank(self, playerTank):
    # 遍历全部敌方坦克,检查有没有碰撞
    if pygame.sprite.collide_rect(self, playerTank):
        # 如果碰撞了,就保持原来的位置
        self.rect.left = self.prvX
        self.rect.top = self.prvY

在坦克移动下面调用该函数

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

    # 获取窗口事件
    self.getPlayingModeEvent()

    # 显示我方坦克
    MainGame.playerTank.draw(MainGame.window)

    # 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
    self.drawEnemyTank()

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

    # 更新窗口
    pygame.display.update()
# 遍历坦克列表,展示坦克并且移动
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)
        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)

                MainGame.enemyTankBulletList.remove(bullet)

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



运行一下,看看结果

2. 实现敌方坦克间的碰撞

敌方坦克与敌方坦克也是不能穿模的,需要实现一下
这个的代码跟上面的差不多

在敌方坦克类中添加敌方坦克间碰撞检测函数

def collideEnemyTank(self, enemyTankList):
    for tank in enemyTankList:
        if pygame.sprite.collide_rect(self, tank) and tank != self:
            self.rect.left = self.prvX
            self.rect.top = self.prvY

在主类中的drawEnemyTank()函数中调用

# 遍历坦克列表,展示坦克并且移动
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)
        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)

完整的drawEnemyTank()函数

def drawEnemyTank(self):
    # 如果当前坦克为0,那么就该重新生成坦克
    if len(MainGame.enemyTankList) == 0:
        # 一次性产生三个,如果剩余坦克数量超过三,那只能产生三个
        n = min(3, MainGame.enemyTankTotalCount)
        # 如果最小是0,就说明敌人坦克没有了,那么就赢了
        if n == 0:
            print('赢了')
            return
        # 没有赢的话,就产生n个坦克
        self.initEnemyTank(n)
        # 总个数减去产生的个数
        MainGame.enemyTankTotalCount -= n
    # 遍历坦克列表,展示坦克并且移动
    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)
            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,看看结果

发现实现啦

3. 实现玩家子弹与敌方坦克间的碰撞

在两个坦克类中增加生命值减少函数,默认情况下,每次减少一点生命值

def loseLife(self, value = 1):
    self.life -= value

在子弹类中增加碰撞检测函数

def playerBulletCollideEnemyTank(self, enemyTankList):
    # 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):
        	# 坦克被击中就扣减生命值
            tank.loseLife(self.damage)
            # 把子弹设置为销毁状态
            self.isDestroy = True

在drawPlayerBullet()函数中调用

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()
            bullet.playerBulletCollideEnemyTank(MainGame.enemyTankList)
        else:
            playerBulletList.remove(bullet)

运行一下,我们就可以看到击中敌方坦克时,敌方坦克会变色,因为生命值发生了变化

在这里插入图片描述

4. 实现敌方子弹与我方坦克间的碰撞 和 玩家复活

首先我们要考虑到,当玩家生命值不为0时,被击中了需要在出生的复活,此时需要给玩家坦克类添加一个属性,用来判断此时玩家是否要复活

# 重生
self.isResurrecting = False

在子弹类中增加碰撞检测函数

def enemyBulletCollidePlayerTank(self, playerTank):
    # 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)
        else:
            playerTank.loseLife(self.damage)
            playerTank.life = max(0, playerTank.life)
            if playerTank.life != 0:
                playerTank.isResurrecting = True
        # 让子弹销毁
        self.isDestroy = True

在drawEnemyBullet()函数中调用

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

修改我方坦克类的draw()函数

def draw(self, window, x, y):
    # 坦克生命中为0,表示已经死亡,不再展示坦克
    if self.life <= 0:
        return
    # 判断坦克是否复合
    if self.isResurrecting:
        # 把坦克位置设置为指定的重生位置
        self.rect.left = x
        self.rect.top = y
        self.isResurrecting = False
        self.direction = 'UP'
    # 获取展示的对象
    self.image = self.images[max(self.armor - 1, 0)][self.direction]
    # 画出图片
    window.blit(self.image, self.rect)

在while循环中修改draw()函数参数

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

测试一下,看看能不能实现玩家死亡

5. 爆炸效果类

现在敌方坦克和我方坦克都可以被消灭了,但是消灭的效果不是很好,下面增加一个爆炸效果类,更好地看到坦克被消灭

import pygame.image


class Explode:
    def __init__(self, object, size):
    	# 获取爆炸对象的位置
        self.rect = object.rect
        self.images = []
        self.images.append([
            pygame.image.load('../Image/Explode/Explode50x50.png'),
            pygame.image.load('../Image/Explode/Explode50x50.png'),
            pygame.image.load('../Image/Explode/Explode50x50.png'),
            pygame.image.load('../Image/Explode/Explode50x50.png'),
            pygame.image.load('../Image/Explode/Explode50x50.png')
        ])
        self.images.append([
            pygame.image.load('../Image/Explode/Explode25x25.png'),
            pygame.image.load('../Image/Explode/Explode25x25.png'),
            pygame.image.load('../Image/Explode/Explode25x25.png'),
            pygame.image.load('../Image/Explode/Explode25x25.png'),
            pygame.image.load('../Image/Explode/Explode25x25.png')
        ])
        self.mode = 0
        if size == 25:
            self.mode = 1
        self.index = 0
        self.image = self.images[self.mode][self.index]
        self.isDestroy = False

    def draw(self, window):
    	pass

这里我分为了两种爆炸效果,它们的烦恼不同,即爆炸效果的图片大小不一样,为了让爆炸效果能看到,而不是一闪而过,我让图片加载五次

修改draw()函数

def draw(self, window):
    # 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.mode][self.index]
        self.index += 1
        window.blit(self.image, self.rect)
    else:
        self.isDestroy = True
        self.index = 0

在主类中添加爆炸列表

class MainGame:

    ...
    
    # 爆炸列表
    explodeList = []

	...

在主类中增加显示爆炸效果函数

def drawExplode(self):
    for e in MainGame.explodeList:
        if e.isDestroy:
            MainGame.explodeList.remove(e)
        else:
            e.draw(MainGame.window)

在while循环中调用drawExplode()

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

    # 获取窗口事件
    self.getPlayingModeEvent()

    # 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()

6. 为子弹爆炸添加爆炸效果

子弹爆炸添加爆炸效果

修改子弹类的move()函数

def move(self, explodeList):
    if self.accumulation >= 1:
        self.accumulation = 0
        if self.direction == 'LEFT':
            self.rect.left -= self.speed
        elif self.direction == 'UP':
            self.rect.top -= self.speed
        elif self.direction == 'DOWN':
            self.rect.top += self.speed
        elif self.direction == 'RIGHT':
            self.rect.left += self.speed
        # 检查子弹是否出界
        self.checkBullet(explodeList)
    else:
        self.accumulation += 0.20

def checkBullet(self, explodeList):
    toDestroy = False
    # 如果出界,就设置为销毁
    if self.rect.top < 0 or self.rect.top > 600:
        toDestroy = True
    if self.rect.left < 0 or self.rect.right > 900:
        toDestroy = True
    if toDestroy:
        explode = Explode(self, 25)
        explodeList.append(explode)
        self.isDestroy = True

此时如果子弹击中边界,就会出现爆炸效果

修改调用处

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)
        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)
        else:
            bullet.source.bulletCount -= 1
            MainGame.enemyTankBulletList.remove(bullet)

试一试效果,看看子弹出界有没有爆炸效果

7. 为坦克爆炸添加爆炸效果

修改 子弹类中 playerBulletCollideEnemyTank() 函数和 enemyBulletCollidePlayerTank() 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)

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)
        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

修改调用处

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)
        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)
        else:
            bullet.source.bulletCount -= 1
            MainGame.enemyTankBulletList.remove(bullet)
