朋友 : 這I;P的成就咋搞的?
我 : 不是我干的, 都是Google Play Service搞定的, 要看API文檔不~
朋友 : 知道你沒個服務器搞這個, 我就想問問你怎么跟蹤成就事件的? 就是你怎么判斷成就完成了呢?
我 : 啊, 這個啊...簡單的怕你罵我...
開說 ---- 我覺得呢, 每個問題都有N多的解決方案, 但基于人性考慮呢, 簡單,好敲, 省力氣的, 才是好方案...
成就事件跟蹤呢, 簡單考慮就是實時/定時事件點上更新成就所需數據, 并在指定的事件點上(也可以實時)進行檢查判斷, 以決定是否解鎖.
因此, 我用了如下的類型存放成就所需數據:
private Type(int id, int target, boolean inc, boolean global) {
this.id = id;
this.target = target;
this.inc = inc;
this.global = global;
}
id: 成就標識;
target: 成就目標閾值;
inc: 遞增類型(用于區別大于/小于);
global: 全局成就類型(就是全關卡通用, 反之每次running后清零);
有了上面的結構, 實例化各個成就數據, 然后在running過程中的每個事件中, 比如, Tary移動, 指令調用, 執行成功等等地方, 累計相應的成就值就好; 當執行成功時(這個是I;P成就的前提條件), 檢查每一個成就實例, 哪個滿足條件了, 就解鎖哪個. 很簡單不是? 下面是代碼:

對了, 最后還好, 朋友只是鄙視了下, 沒打沒罵...
