Another Question about Execution Order

Questions & Answers
1

Let’s say there are scripts a and b.

Is the order:

a Update → b Update → a LateUpdate → b LateUpdate

or

a Update → a LateUpdate → b Update → b LateUpdate?

To my understanding of Execution Order of Event Functions, Update is fired first across all MonoBehaviours, then LateUpdate passes across them. So the first line you typed is the correct interpretation.

a Update → b Update → a LateUpdate → b LateUpdate

I did an experiment for this to confirm: I created ScriptA and ScriptB, which are mostly clones of one another, with exception to what they log to the console. The result is in an image I’ve attached.

public class ScriptA : MonoBehaviour {
	bool loggedUpdate = false;
	bool loggedLate = false;
	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		if (!loggedUpdate)
		{
			Debug.Log("A UPDATE");
			loggedUpdate = true;
		}
	}

	void LateUpdate()
	{
		if (!loggedLate)
		{
			Debug.Log ("A LATE");
			loggedLate = true;
		}
	}
}
