The Delay field specifies the amount of time to wait before starting the transition after the property has been changed. This delay is optional and can be set to null if no delay is desired. The value is expressed in seconds and is represented as a nullable float (System.Nullable<System.Single>).

To use the Delay field, assign a float value representing the delay in seconds. If you do not want any delay, you can set it to null.

Example usage:

TransitionDesc transition = new TransitionDesc();
transition.Delay = 0.5f; // Set a delay of 0.5 seconds
