Arbor

Hi

When starting game, FSMInternal invokes state.EnableState( true,true );

It in turn, calls behaviour.OnStateAwake()
and behaviour.OnStateBegin();

Problem:
I have script on first state. It always gets OnStateAwake() + OnStateBegin() during FSMInternal.Start()
My script has [SerializeField] GameObject[] prefabArray;

On first frame, I get exception from the script - it has empty array, because it was enabled during OnStateBegin()
Unity didn't have time yet to load array with data

Next frame, unity serialized the array with prefabs, and everything is ok

Here is screenshot of problem:

Hi.

I checked the behavior of the problem, but I could not reproduce it.

Checking environment:
Unity 5.6.2f1
Arbor 2.1.2

Method for checking:

• Create a new project with Unity 5.6.2f1.
• Imported Arbor 2.1.2.
• Create script below.

  Code: Select all

  using UnityEngine;
  using System.Collections.Generic;
  using Arbor;
  
  public class TestStartSerialize : StateBehaviour
  {
  	[SerializeField] List<GameObject> prefabs;
  	
  	// Use this for enter state
  	public override void OnStateBegin()
  	{
  		if (prefabs != null)
  		{
  			Debug.Log("OnStateBegin : " + prefabs.Count);
  		}
  		else
  		{
  			Debug.LogError("OnStateBegin : prefabs is null");
  		}
  	}
  }
  

• Attach & set to Start state and execute.

If there is any difference in the checking method, please let me know.

Thank you!

I've solved the problem

It was because I had 2 FSM with same names "myAbilitiesFSM"
