public static void Destroy(Object obj, float t)

Parameters

obj

Object
The object to destroy.

t

float
The optional amount of time to delay before destroying the object.

Remarks

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. Unity’s 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.

Destroy is inherited from the UnityEngine.Object base class.
