寫這個游戲已經有一段時間了,一直在實現各種新功能,從最開始的地圖上只有坦克,發子彈還是一個大問題到現在可以兩個人一起玩,還是花了不少心思的,現在坦克的速度更快,電腦坦克也不會撞牆.雖然游戲性沒有經典坦克大戰那麼強,但是還是可以用來休閒娛樂一下,這個用了很多最近學到的新知識,模仿俄羅斯方塊,還有一些小技巧,比如可以同時按觸發多個按鍵事件,對子彈的處理等.
左邊的坦克用W D S A控制移動,H發射子彈,每次最多出現5顆子彈,右邊的坦克用上下左右箭頭控制移動,L鍵發射子彈,互不干擾.Q鍵可以直接退出游戲,游戲結束後按Y鍵可以繼續游戲.為了結構清晰游戲分為Mywar Shoot Tanks 3個類.
（第二次用插入代碼，之前一直都不懂這功能，我奧特蛋了 (*^__^*) 嘻嘻……）
