這段代碼使用Arduino和Adafruit SSD1306庫(kù)在OLED顯示器上實(shí)現(xiàn)了一個(gè)基本的坦克戰(zhàn)斗游戲。以下是游戲的主要特點(diǎn)和功能：
?玩家坦克：玩家控制一輛坦克，它可以通過連接到特定引腳的按鈕向上、向下、向左和向右移動(dòng)。坦克定時(shí)自動(dòng)發(fā)射子彈。
?敵人坦克：有6輛敵人坦克在屏幕上隨機(jī)移動(dòng)。每個(gè)敵方坦克也會(huì)向玩家的坦克發(fā)射子彈。
?子彈：玩家和敵人的坦克都會(huì)射擊子彈。子彈的速度是坦克移動(dòng)速度的兩倍。當(dāng)玩家的子彈擊中敵人的坦克時(shí)，敵人的坦克就會(huì)被摧毀，玩家就會(huì)獲得一分。敵人的子彈不會(huì)影響其他敵人的坦克。
?碰撞檢測(cè)：游戲檢查玩家的子彈與敵人坦克之間的碰撞，以及敵人的子彈與玩家坦克之間的碰撞。如果敵人的子彈擊中玩家的坦克，玩家就會(huì)失去一條生命。
?生命和得分：玩家一開始有三條生命。每摧毀一輛敵方坦克，玩家的分?jǐn)?shù)就會(huì)增加。如果玩家失去所有三條生命，游戲?qū)@示“游戲結(jié)束”并重置。
?游戲重置：當(dāng)玩家的生命值為零時(shí)，游戲會(huì)顯示“游戲結(jié)束”屏幕，然后重新開始，重置分?jǐn)?shù)、玩家生命值和敵方坦克位置。
?顯示：游戲在OLED屏幕上顯示，游戲區(qū)和計(jì)分區(qū)用一條豎線隔開。得分區(qū)域顯示當(dāng)前得分和剩余命值。
?初始化和設(shè)置：在游戲開始時(shí)，敵人的坦克會(huì)出現(xiàn)，玩家的坦克會(huì)出現(xiàn)在屏幕的中下方。游戲以一個(gè)顯示“Tank Battle”的啟動(dòng)畫面開始。
