執行結果：

通過鍵盤或者滑鼠來控制角色播放指定的動畫是遊戲中十分常見的功能，而我們之前的程式只能播放預設的一個動畫，而且每個動畫的例項都包含了資源，而我們繪製的時候需要資源，例項並不需要包含資源。我們只用指標指向那個資源就可以了。

我們可以首先對微軟官方的那個骨骼動畫檔案進行一次封裝。用來建立動畫例項。功能就是實現各種動畫的操作，比如根據名字播放骨骼動畫例項、渲染骨骼動畫等，並且儲存了動畫的資源。

		)))
		return NULL;

	return pAnimController;
}
 

然後我們對這個類進行二次封裝，來建立一個動畫例項類。每個例項僅僅包含一個指向動畫資源的指標，這樣就可以僅僅儲存一份資源了。然後我們還需要拷貝一份動畫控制器。為什麼呢？因為如果我們有多個例項，一個動畫控制器控制了所有的例項的動畫播放，那麼他們做的動畫就會完全一樣，這完全就不是我們想要的結果啊。所以我們為每個例項拷貝一份動畫控制器，分別播放不用的動畫。實現方法直接呼叫微軟寫好的API就OK了。注意第一個骨骼動畫類的動畫控制器不可以直接使用，它僅僅供動畫例項類克隆用的。

}

最後當我們建立一個角色時直接建立對應的動畫例項類，當然在此直接先建立骨骼動畫類，把動畫資源載入進來。

然後通過動畫例項類來進行各種操作，就會十分的方便了。
