Diagram Update: Execution Order of Event Functions

Web Resources
1

Friendly request to have the Execution Order diagram updated.

In its current state it suggests the following order

  • Awake()
  • OnEnable()
  • Start()

I’ve come to learn the actual order is

  • For each script call Awake() then OnEnable(), then go to the next script
  • Start()

I imagine having an accurate diagram will help to avoid bugs / confusion for future devs.

Thanks in advance.

Hmmm. Guess you’re right. I think the “3. Start()” isn’t meant to mean Start() instantly follows OnEnable(). I’ll see if the docs team can fix this.

using UnityEngine;

public class test1 : MonoBehaviour {

    void Awake()
    {
        Debug.Log("test1: Awake");
    }

    void OnEnable()
    {
        Debug.Log("test1: OnEnable");
    }

    void Start()
    {
        Debug.Log("test1: Start");
    }
  
}

using UnityEngine;

public class test2 : MonoBehaviour {

    void Awake()
    {
        Debug.Log("test2: Awake");
    }

    void OnEnable()
    {
        Debug.Log("test2: OnEnable");
    }

    void Start()
    {
        Debug.Log("test2: Start");
    }
   
}

test1: Awake
test1: OnEnable
test2: Awake
test2: OnEnable
test1: Start
test2: Start
