The HasChanges property of the SerializedProperty class is a virtual boolean property that indicates whether the current set value of the property differs from its actual value. This property is useful for determining if a property has been modified since it was last saved or initialized.
To use the HasChanges property, simply access it on an instance of SerializedProperty. It will return true if the property's current value is different from its original or last saved value, and false otherwise.
// Example usage of the HasChanges property
SerializedProperty myProperty = ...; // Assume this is initialized
if (myProperty.HasChanges)
{
// Perform actions if the property has changed
// For example, save the changes or notify the user
}
