Save everything except position

[qest43]

So I have some checkpoints in game, I activate them when I interact with them by 'E' key. Then I trigger in script

Code: Select all

SaveSystem.SaveToSlot(GameManager.Instance.currentSaveSlot);

But sometimes I die, and I want to keep player inventory, and all this stuff and respawn him in last checkpoint. I could do that in code ofc, just refill HP and teleport etc. but I want to use this also when I exit game, I want to save everything but when player load save slot he will start in last checkpoint he visited with kept inventory and all this stuff.

Hi,

Since you don't want to restore the saved data except for checkpoint location, I recommend handling the respawn in code (refill HP, teleport player). Get the checkpoint position from the UCCSaver component's saved data. Example:

Code: Select all

public Vector3 GetCheckpointLocation()
{ // Assume we run this on the player.
    var uccSaver = GetComponent<uccSaver>();
    var s = SaveSystem.currentSavedGameData.GetData(uccSaver.key);
    var data = SaveSystem.Deserialize<UCCSaver.Data>(s);
    return data.position;
}

To handle exiting the game, you can make a subclass of UCCSaver. Something like:

Code: Select all

public class MyUCCPlayerSaver : UCCSaver // Put this on player instead of UCCSaver.
{ // Assumes you're calling SaveSystem.SaveToSlotImmediate() or using AutoSaveLoad to save when quitting.
    private bool isQuitting = false;
    
    void OnApplicationQuit()
    {
        isQuitting = true;
    }
    
    public override string RecordData()
    {
        Vector3 checkpointLocation = GetCheckpointLocation();
        var s = base.RecordData();
        if (isQuitting)
        { // Store previous checkpoint position in save data:
            var data = SaveSystem.Deserialize<UCCSaver.Data>(s);
            data.position = checkpointLocation;
            s = SaveSystem.Serialize(data);
        }
        return s;
    }
}
