Editing Complete Example Scripts (section)

= Maintenance/update code which runs once per save load and shows a message when a mod is updated or first loaded =
*Requires Skyrim v1.6+: All event based, so no polling is necessary. For this method to work, two scripts are needed as [[OnPlayerLoadGame - Actor|OnPlayerLoadGame]] will not fire from a Quest script.
