Destroys the specified object. If a time delay (t) is specified, destruction occurs after t seconds have elapsed. The timer starts from the moment Destroy is called. Actual object destruction is always delayed until after the current Update loop, but always happens before rendering.
If the object is a component, only that component is removed and destroyed. If the object is a GameObject, the GameObject, all its components, and all its transform children are destroyed together.
Once Destroy(obj, t) is called, the object is scheduled for destruction after t seconds, regardless of whether the script component that called it is later disabled or destroyed.
Destroy is safe to call on objects that might already be destroyed or null. If the object is already destroyed before the scheduled time, no error is thrown when the timer expires. Unitys internal system tracks the object's state and won't attempt to destroy it again.
The delay parameter t is affected by Time.timeScale. If Time.timeScale is set to 0 (for example, if the game is paused), the destruction is delayed until time resumes.
