Save System Question

[hillka28]

Hi Tony,

I'm working on implementing the save system into my game, and I'm running into the following error when I try to load the data:

Code: Select all

Dialogue System: Lua code 'Variable={Alert="", activeHuntQuest="Pest Removal", Deck=2, enemiesKilled=0, enemiesToKill=5, enemyTypeToKill="goblin", ["chest.0"]=false, ["chest.1"]=false, ["chest.2"]=false, Actor="Guard", Conversant="Player", ActorIndex="Route_1_West_Guard", ConversantIndex="Player"}; Item["My_First_Deck"].State="success"; Item["Pest_Removal"].State="active"; Item["Pest_Removal"].Track=true; Item["Pest_Removal"].Entry_1_State="active"; Item["Definitely_Not_Bribery"].State="active"; Actor={Player={Name="Player", Pictures="[]", Description="You", IsPlayer=true}, Eredith={Name="Eredith", Pictures="[]", Description="Wisewoman", IsPlayer=false}, Route_1_West_Guard={Name="Route 1 West Guard", Pictures="[]", Description="Guard", IsPlayer=false, Display_Name="Guard"}, Dolores={Name="Dolores", Pictures="[]", Description="Baker", IsPlayer=false}, Sana={Name="Sana", Pictures="[]", Description="Healer", IsPlayer=false, HasMet=false}, Tabor={Name="Tabor", Pictures="[]", Description="Shopkeeper", IsPlayer=false, HasMet=false}, Blackbread={Name="Blackbread", Pictures="[]", Description="Banker", IsPlayer=false, HasMet=false}}; StatusTable = ""; RelationshipTable = ""; ' threw exception 'Cannot assign to a null value. Are you trying to assign to a nonexistent table element?.'

I am saving the data in one file via: string save =

Code: Select all

PixelCrushers.DialogueSystem.PersistentDataManager.GetSaveData();
        ES3.Save<string>("dbSave", save);

Then I am loading the data via:

Code: Select all

PixelCrushers.DialogueSystem.PersistentDataManager.ApplySaveData(ES3.Load<string>("dbSave"));

The error is promising since it appears to be holding the right data, I'm just not sure why it won't then apply that data. Any insight would be much appreciated!

Hi,

What versions of Unity and the Dialogue System are you using?

If you're not on DS version 2.2.14 (current version as of this reply), can you back up your project and update DS?

Does the scene with your MainMenu script also contain a Dialogue Manager GameObject?

Once again, the obvious solution was right in front of me. My main menu scene did not contain a Dialogue Manager game object as you pointed out, and once I added it everything is working perfectly. Thanks for such great support!

Glad to help!
