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.leftself.prvY = self.rect.topif self.direction == 'LEFT':if self.rect.left > 0:self.rect.left -= self.speedelif self.direction == 'UP':if self.rect.top > 0:self.rect.top -= self.speedelif self.direction == 'DOWN':if self.rect.top < 555:self.rect.top += self.speedelif self.direction == 'RIGHT':if self.rect.left < 855:self.rect.left += self.speedelse: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 = 30else:if self.accumulationMax >= 1:self.accumulationMax = 0# 记录上一次的位置self.prvX = self.rect.leftself.prvY = self.rect.topif self.direction == 'LEFT':if self.rect.left > 0:self.rect.left -= self.speedelif self.direction == 'UP':if self.rect.top > 0:self.rect.top -= self.speedelif self.direction == 'DOWN':if self.rect.top < 555:self.rect.top += self.speedelif self.direction == 'RIGHT':if self.rect.left < 855:self.rect.left += self.speedself.step -= 1else: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.prvXself.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.prvXself.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 -= 1MainGame.enemyTankList.remove(tank)

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.prvXself.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 -= 1MainGame.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 -= 1MainGame.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

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.damageplayerTank.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 -= 1MainGame.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 = xself.rect.top = yself.isResurrecting = Falseself.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.imageclass Explode:def __init__(self, object, size):# 获取爆炸对象的位置self.rect = object.rectself.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 = 0if size == 25:self.mode = 1self.index = 0self.image = self.images[self.mode][self.index]self.isDestroy = Falsedef 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 += 1window.blit(self.image, self.rect)else:self.isDestroy = Trueself.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 = 0if self.direction == 'LEFT':self.rect.left -= self.speedelif self.direction == 'UP':self.rect.top -= self.speedelif self.direction == 'DOWN':self.rect.top += self.speedelif self.direction == 'RIGHT':self.rect.left += self.speed# 检查子弹是否出界self.checkBullet(explodeList)else:self.accumulation += 0.20def 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 = Trueif self.rect.left < 0 or self.rect.right > 900:toDestroy = Trueif 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 -= 1MainGame.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 = Trueif 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.damageplayerTank.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 -= 1MainGame.enemyTankBulletList.remove(bullet)
