Instantiate problem

[pplasto]

i have a Prefab in Assets folder, this prefab has a blackboard, and the blackboard has a variable to linked this prefab’s child gameObject.
and when i instantiate it, in hierarchy the blackboard variable still linked to Assets folder Prefab..

like this:

my spawn code is:

1 2 3 4 5 6 7 8 9 10

public class TestInstantiate : MonoBehaviour {     public GameObject Prefab;     public int frameCount = 1;     public void Update()     {         if (Time.frameCount == frameCount)             Instantiate(Prefab);     } }

my unity Version is 5.3.4f1

Hello,
Wow… that’s a critical bug. Thanks!
To fix this, please open up Blackboard.cs and in method ‘OnBeforeSerialize’, add at the very first line of the method (above #if UNITY_EDITOR) this hasDeserialized = false;
Also, please do exactly the same in Graph.cs in the first line of it’s ‘OnBeforeSerialize’

Thanks a lot for reporting!

This is still happening on the latest version

Hello Luis,
This was fixed way back in 2016 🙂 I can’t reproduce a case where this happens.
Can you please elaborate?
Thank you.

I noticed it is not about the blackboard, but the graph’s variables.

1) create a new game object in scene call it “root”
2) create a child of that game object
2) add fsm owner component to the “root” object
3) add state with action, “Set visibility”
4) In the action “Set Visibiity” set the target to the child object
5) make the “root” gameobject -> prefab
6) Instantiate that prefab by code
7) notice the “Set Visibility” node is chaning the prefab, and not the instance child.

Hello again,

I followed your steps exactly and everything works as expected. The “Instantiated” child is affected and not the prefab child.
So, only one question remains 🙂
What exact version of NodeCanvas and Unity are you using just to confirm?

Thanks.
