[Unity] UGUI新增刪除子canvas 造成unity閃退 crash 崩潰問題分析。

阿新 • • 發佈：2018-11-03


專案裡，為了做引導， 把 需要高亮按鈕控制元件  加上 Canvas  GraphicRaycaster 元件，然後設定大的層級。  

結束時再移除這些元件。

沒想到頻繁 造成崩潰。

說懷疑是Destroy後，Unity存在一個BUG導致CanvasRenderer還繼續訪問了該物體（已經為NULL）

然後做了延時Destory就好了。


然後這邊就想到了一個思路。   在LateUpdate裡把 Canvas  GraphicRaycaster 元件 移除， 就是等渲染結束再移除canvas元件，， 就不崩潰了。


（最近遇到一個新的閃退情況， 原因應該是一樣的：

  就是 子節點 含有canvas的，移除父節點上的canvas unity就會閃退崩潰（編輯器手動操作都可復現，unity 5.5.x）。
目前方案，先把子節點的canvas先禁用掉，然後再移除父節點的，再恢復子節點的canvas）
