The NonSerialized attribute marks a variable to not be serialized.

Apply to public fields to prevent Unity from serializing the field and displaying it in the Inspector.

Apply to a private field to stop the field being serialized during a hot reload operation, such as after an assembly is recompiled, or during a domain reload operation before entering Play mode.

For more information on serialization, see Script Serialization.
