Update database at runtime
Posted: Thu Jul 18, 2019 2:40 pm
Hello Toni,
I've been trying to use the Dialogue System to implement all the dialogue component of a Teleport system. Meaning that the conversations where the player chooses its destination are to be handled by the Dialogue System in cooperation with my custom scripts.
Right now i am trying to implement the system in the following fashion: i have two scripts attached to a gameobject called "Portal", one of them (TeleportComponent.cs) holds the following information (right now simple stuff, just to give me an idea of what sort of variables i will need to hold): ID (int) and all the possible destinations of that specific portal (List<string>); the other (DialogueSystemTeleportController.cs) is the one responsable of generating (Awake method) and adding a conversation holding all the possible destinations from which the player can choose from through the typical Dialogue System UI.
The code of the "DialogueSystemTeleportController.cs" (i have tried to adapt it from https://www.pixelcrushers.com/dialogue_ ... baseInCode ***):
*** Important note: In contrast with the provided example on the referenced link which is creating an instance of a "DialogueDatabase" scriptable object and adding it to the "DialogueManager" later, my code is actually getting a previously made database and changing it at runtime, in this case generating and adding a conversation. This was made this way since i thought it would be useful to have a database solely dedicated for holding all my custom teleport system conversations, including a first step dialogue conversation, called "Teleport confirmation conversation" pictured in the following image:
"Teleport confirmation conversation" tree.
This basic conversation holds two nodes "Teleport..." and "Cancel", which are pretty self explanatory. If the player decides to teleport and chooses the "Teleport..." node, then the following sequence is executed:
Else, if the player decides to cancel and chooses the "Cancel" node, the dialogue simply ends without anything special happening.
My problem is that the database does not seem to be updated during runtime, meaning that whenever the "OnConversationEnd" is called i get the following warning:
and nothing happens. Although when i stop the simulation (with the "OnDisable" method commented out), my generated conversation is added to the referenced database.
To conclude this long post, here is my question:

To conclude this long post, here is my question:
- Is there any way to update a previously created (OnEditor) database with runtime generated data (in my case, a conversation)? If so, is there any optimal way of doing such thing?
