The SetSnapshotFunction method is part of the UndoSystem class within the Sandbox.Helpers namespace. This method is marked as obsolete and is no longer functional. It was originally intended to set a function that would create a snapshot for the undo system. However, due to its obsolescence, it is recommended to manually create and restore snapshots within the undo/redo actions provided to UndoSystem.Insert.
Since SetSnapshotFunction is obsolete, it is advised not to use this method in new code. Instead, manage snapshots manually by implementing them in the actions passed to UndoSystem.Insert. This approach ensures that your undo/redo functionality remains robust and up-to-date with the current API standards.
// Example of how to manually handle snapshots in the UndoSystem
// Define undo and redo actions
Action undoAction = () => {
// Code to revert changes
};
Action redoAction = () => {
// Code to reapply changes
};
// Insert the actions into the UndoSystem
UndoSystem.Insert("Change Title", undoAction, redoAction);
