# BlackboardEvents sent by Save and Load

The `SaveAndLoad` script will automatically connect with the `MainBlackboard`. Events will be sent which other scripts can listen for.

The event `topic` and `gameId` will always be "Save and Load" and "Game Data" respectively. The `status` value will indicate which step triggered the event, and the `obj` will be the `saveGameId` that is being managed.

```csharp
// topic will always be "Save and Load"
// gameId will always be "Game Data"
// status will indicate which save or load step triggered the event
// obj will have the SaveId being managed, but may be null in some cases

// EVENTS SENT (will be in the status value of the BlackboardEvent)
// "Save Start" [obj = the SaveGameId being saved]
// "Save End" [obj = the SaveGameId being saved]
// "Load Start" [obj = the SaveGameId being loaded]
// "Load End" [obj = the SaveGameId being loaded]

// Examples on how to listen for BlackboardEvents from the Save and Load module
public override void ReceiveEvent(BlackboardEvent blackboardEvent)
{
    // Save Start and Save End events do not include any data in
    // the obj value, so they are ignored here.
    if (blackboardEvent.topic == "Save and Load" 
        && blackboardEvent.gameId == "Game Data" 
        && blackboardEvent.status == "Save Start")
    {
        PreSaveActions();
    }
        
    if (blackboardEvent.topic == "Save and Load" 
        && blackboardEvent.gameId == "Game Data" 
        && blackboardEvent.status == "Save End")
    {
        PostSaveActions();
    }
}
```

There will also be an event sent when the Game List is saved or loaded:

```csharp
// Do something when the Game List is saved...
if (blackboardEvent.topic == "Save and Load" 
    && blackboardEvent.gameId == "Game List"  // Not "Game Data" here!
    && blackboardEvent.status == "Saved")
{
    // Game List was saved!
}

// Do something when the Game List is loaded...
if (blackboardEvent.topic == "Save and Load" 
    && blackboardEvent.gameId == "Game List"  // Not "Game Data" here!
    && blackboardEvent.status == "Loaded")
{
    // Game List was loaded!
}
```
