When does Time.frameCount increase?

I wrote this script to commit on change Time.frameCount

:

using UnityEngine;

public class OnFrameCounterDetector : MonoBehaviour {

    int frameNumber = 0;
    string prevMethod;

    private void Awake() {
        Time.fixedDeltaTime = 1 / 60;
        prevMethod = System.Reflection.MethodBase.GetCurrentMethod().Name;
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnEnable() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void Start () {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void FixedUpdate() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void Update () {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void LateUpdate() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnWillRenderObject() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnPreCull() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnBecameVisible() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnBecameInvisible() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnPreRender() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnRenderObject() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnPostRender() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnRenderImage(RenderTexture source, RenderTexture destination) {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnDrawGizmos() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnGUI() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnApplicationPause(bool pause) {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void OnDisable() {
        CheckFrameCount(System.Reflection.MethodBase.GetCurrentMethod().Name);
    }

    private void CheckFrameCount(string callback) {
        if (Time.frameCount > frameNumber) {
            Debug.LogFormat("frameCount changed between {0} and {1}", prevMethod, callback);
            frameNumber = Time.frameCount;
        }
        prevMethod = callback;
    }
}

      

        
        
        
      

    

Inside the editor, I got a change between OnGUI

OR OnRenderObject

and FixedUpdate

, but the scene was almost empty, with only one camera and a game object with Sprite Renderer

on it.

The difference lay in the fact that if I had chosen a gaming facility or a camera in the hierarchy, if the GO was selected, then OnRenderObject

will be signaled if there is no (ie keep the camera in the hierarchy) OnGUI

.

You can use this script in more detailed scenes as most callbacks are not called at all in a simple scene, curious about the results.

By the way, I did not add coroutines with different outputs, they can be added, although it is very easy to catch more "moments" in the game loop, like between Update and LateUpdate, etc.
