前言

致敬經典的warcraft，《warcraft java版》是一款即時戰略題材單機游戲，采用魔獸原味風格和機制。收集資源，建造防御工事，消滅所有敵軍。
人類：洛丹倫人類聯盟自獸人首次穿過黑暗之門時便告成立。他們堅韌不拔，勇敢無畏，身穿堅甲，手握利刃，英勇迎敵。
獸人：獸人是一個粗獷而堅韌的種族，他們身穿簡單的皮毛和帶有尖刺的皮甲，以肆意兇狠的戰斗風格而聞名。

用java語言實現，采用了swing技術進行了界面化處理，設計思路用了面向對象思想。

主要需求

1、玩家可以自己選擇陣營：人類（Human）和獸人（Orc）兩個陣營可以挑。
2、主要資源：

• 黃金：黃金在Warcraft 中是主要的資源。黃金被用來建造新的建筑物，訓練單位和研究升級。黃金在中立的建筑物也被用來購買雇傭兵，英雄物品，或啟用特殊的服務。
• 木材：木材和黃金類似，也是主要活動的消耗資源之一。所有種族都使用木材生產戰爭所需的許多不同的結構的武器和機器。

3、建筑系統：
不同建筑的建造成本、時間和目的各不相同。城鎮大廳可以訓練工人和存放資源，有些建筑可以訓練戰斗單位，還有的可以讓玩家完成科技升級或解鎖不同類型的單位。

3、操作系統：

擇和移動：使用鼠標左鍵點擊一個單位或建筑，就可以查看相應的狀態以及可以下達的指令。選擇單位之后，玩家可以通過點擊鼠標右鍵下達移動指令，或者點擊界面底部指令面板上的按鈕（或按下相應的快捷鍵）來指揮該單位。
按住鼠標左鍵并拖拽即可拉出一個矩形的方框，玩家可以通過這種方式選擇多個單位，這也被稱之為“框選”。選擇多個單位之后，玩家可以一次性向所有選中的單位下達指令。玩家還可以按下Tab鍵來循環切換查看各個單位的指令面板。
編隊：選擇多個單位或建筑后，玩家可以按下Ctrl+任意數字鍵，以此將選中的單位編為一隊。編隊之后，玩家只需要按下該數字鍵就可以再次選中相應的編隊。

總結

通過此次的《warcraft java版》游戲實現，讓我對swing的相關知識有了進一步的了解，對java這門語言也有了比以前更深刻的認識。

java的一些基本語法，比如數據類型、運算符、程序流程控制和數組等，理解更加透徹。java最核心的核心就是面向對象思想，對于這一個概念，終于悟到了一些。
