基于對面向對象編程的思想完成簡單的坦克大戰游戲。主要目的鍛煉面相對象編程思想同樣的在使用python進行游戲編寫時需要安裝pygame模塊

安裝方法：

pycharm安裝方式：File --> setting

游戲中的主要對象有：

坦克父類：BaseTank我方坦克：HeroTank敵方坦克：EnemyTank子彈類：Bullet爆炸類：Explode墻類：Wall主進程：MainGame

定義一個精靈類：

# 定義一個精靈類class BaseItem(Sprite): def __init__(self, color, width, height): # Call the parent class (Sprite) constructor pygame.sprite.Sprite.__init__(self)

坦克父類：

# 坦克父類class BaseTank(BaseItem): # 定義類屬性，所有坦克對象高和寬都是一樣 width = 60 height = 60 def __init__(self, left, top): self.direction = ’U’ # 坦克的方向默認向上 # 存放圖片的字典 self.images = { ’U’: pygame.image.load(’tank_img/p1tankU.gif’), ’D’: pygame.image.load(’tank_img/p1tankD.gif’), ’L’: pygame.image.load(’tank_img/p1tankL.gif’), ’R’: pygame.image.load(’tank_img/p1tankR.gif’) } self.image = self.images[self.direction] # 坦克的圖片由方向決定 self.speed = 5 # 坦克的速度 self.rect = self.image.get_rect() # 設置放置的位置 self.rect.left = left self.rect.top = top self.stop = True # 坦克是否停止 self.live = True # 決定坦克是否消滅了 # 保持原來的位置 self.oldLeft = self.rect.left self.oldTop = self.rect.top # 射擊方法 def shot(self): return Bullet(self) # 坦克的移動 def move(self): # 保持原來的狀態 self.oldLeft = self.rect.left self.oldTop = self.rect.top # 判斷坦克的移動方向 if self.direction == ’U’: if self.rect.top > 0: self.rect.top -= self.speed elif self.direction == ’D’: if self.rect.top + self.rect.height < WINDOW_HEIGHT: self.rect.top += self.speed elif self.direction == ’L’: if self.rect.left > 0: self.rect.left -= self.speed elif self.direction == ’R’: if self.rect.left+self.rect.height < WINDOW_WIDTH: self.rect.left += self.speed # 加載坦克 def displayTank(self): self.image = self.images[self.direction] MainGame.window.blit(self.image, self.rect) # 撞墻處理 def hitWall(self): for wall in MainGame.wallList: if pygame.sprite.collide_rect(wall, self): self.stay() # 處理位置不變 def stay(self): self.rect.left = self.oldLeft self.rect.top = self.oldTop
