Data binding to global blackboards or blackboards from your own unity script

[kevynm]

Hi! I would like to ask if there is a feature where you have your own monobehaviour script and you want to do data binding to a global blackboard variable or any blackboard? Thanks!

Hello,

Can you please explain a bit more of what you mean? Sorry.
Blackboard variables can be data bound to component properties of the same gameobject as the gameobject the Blackboard is attached if that is what you mean yes 🙂
Take a look at this documentation section.

Let me know if you mean something different.
Thanks.

Nevermind, I found a solution for it. I retrieved the variable version of the blackboard properties to have a reference of the values instead of always getting it every update to see if there are changes.

Hey,
Thanks for letting me know.
Yes you can get and store the Variable object if you want. Also, that Variable object has an event you can subscribe to onValueChange. Here is an example:

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

public class Example : MonoBehaviour{   public Blackboard bb;   void Start(){ var variable = bb.GetVariable("myFloat"); variable.onValueChanged += OnValueChanged; }   //name and new value of the variable changed. void OnValueChanged(string name, object value){ //... } }

Cheers!
