Creating DialogueTrees at Runtime

[axdragonxgParticipant]

Is there a way to create DialogueTrees at runtime like you can with BehaviorTrees like shown in the documentation here? There doesn’t appear to be a way set the necessary fields for DT nodes at runtime like you can with behavior tree nodes

Hello,

While there exists the API for creating a dialogue tree, adding and connecting nodes, unfortunately because creating dialogue trees in runtime was not taken into consideration (since it defies the need of a node editor 🙂 ), most of the fields (like for example in StatementNode) are private. With that said, I could make them public in a future version though if that is something required.

Here is how you would create a dialogue tree controller, a simple dialogue tree with two nodes, and assigning it to the controller.
As mentioned earlier though, the StatementNode.statement field is private, thus not much of a use, unless it is made public, so that it is possible to set the statement (the dialogue to be displayed, which is called a “statement” in NodeCanvas).

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

using UnityEngine; using NodeCanvas.DialogueTrees;   public class RuntimeCreateDialogue : MonoBehaviour {   void Start(){ var controller = this.gameObject.AddComponent<DialogueTreeController>(); var tree = ScriptableObject.CreateInstance<DialogueTree>(); var sayNode = tree.AddNode<StatementNode>(); var sayNode2 = tree.AddNode<StatementNode>(); tree.ConnectNodes(sayNode, sayNode2); controller.graph = tree; } }

Please let me know if making the fields public is something you would like in a future version.
Thank you.

Hello,

When would it be possible to implement this?

Thanks.

Hello,

Do you mean the possibility to make dialogue tree graphs purely from code?
I really think that doing so defies the purpose of using a visual graph representation, but if it is requested I can make the necessary changes.
Can you please elaborate on a use case please?

Thank you.
