Latency of the destroy () method

In unity3d, the object. Destroy () method will destroy the passed parameter object, which will cause all references to this object to become null afterwards. However, this method is not executed immediately when it is called. In each frame, all calls to the destroy () method are delayed until all updates () of the current frame () after the call ends (before the real rendering), it is executed in a unified manner. The result is that the object is still available in the same method after destroy () is called, and true is returned for null tests on the object.

In addition, if the latency parameter is input when destroy () is called, destroy () will be executed after a fixed delay period.
