Update not being called?

Unity Engine
1

Hey everyone.
Currently I have an odd situation where it (appears) at least that Update is not getting called at all.
I will get straight to it and show some code as there is not much else to say.

This is the offending Update that is not getting called even though the Start does.

using UnityEngine;
using System.Collections;

public class CameraFacingBillboard : MonoBehaviour
{
    public Camera m_Camera;

    void Start()
    {
        if(m_Camera == null)
            m_Camera = Camera.main;
    }
    
    void Update()
    {
        transform.LookAt(transform.position + m_Camera.transform.rotation * Vector3.forward, m_Camera.transform.rotation * Vector3.up);
        Debug.Log("Update Called!");
    }
}

I create a canvas with this code. (The canvas is world space and has the Billboard look at script on it.)

using UnityEngine;
using System.Collections;

namespace CarlH{
    namespace Tooltips{
        public class ItemTooltip : MonoBehaviour {
        
            public float heightOffset = 1f;
            GameObject canvas;

            public void ActivateTooltip(){
                if(canvas != null)
                    canvas.SetActive(true);
                else
                    CreateCanvas();
            }

            public void DeactivateTooltip(){
                if(canvas != null)
                    canvas.SetActive(false);
                else
                    CreateCanvas();
            }

            void CreateCanvas()
            {
                GameObject tooltipCanvas = (GameObject)Resources.Load("PickupCanvas");
                Vector3 spawnPos = new Vector3(transform.position.x, transform.position.y + heightOffset, transform.position.z);
                canvas = (GameObject)Instantiate(tooltipCanvas, spawnPos, transform.rotation);
                canvas.transform.SetParent(transform, true);
            }
        }
    }
}

I detect how to activate/deactivate the canvas using this script:

using UnityEngine;
using System.Collections;

namespace CarlH{
    namespace Tooltips{
        public class DetectItem : MonoBehaviour {
         
            GameObject hitPickupCache;

            void Update () {
                RaycastHit hit;

                if(Physics.Raycast(transform.position, transform.forward, out hit, 5f)){
                    if(hit.transform.gameObject.tag == "Pickup"){

                        if(hitPickupCache != null){
                            hitPickupCache.GetComponent<ItemTooltip>().DeactivateTooltip();
                            hitPickupCache = hit.transform.gameObject;
                        }
                        else{
                            hitPickupCache = hit.transform.gameObject;
                        }


                        hit.transform.gameObject.GetComponent<ItemTooltip>().ActivateTooltip();

                        if(Input.GetKeyDown(KeyCode.E)){
                            Destroy(hit.transform.gameObject);
                        }
                    }
                    else if(hitPickupCache != null){
                        hitPickupCache.GetComponent<ItemTooltip>().DeactivateTooltip();
                    }
                }
                else if(hitPickupCache != null){
                    hitPickupCache.GetComponent<ItemTooltip>().DeactivateTooltip();
                }
            }
        }
    }
}

The canvas spawns correctly and even funnier, it was actually working a few minutes ago.
Tried restarting Unity so I dont know what it could be.
(Im using Unity 5.4 official release)

Is the script getting deactivated at anypoint? or the GameObject?

3

Yes, it gets activated and deactivated at times. (The GO that is)

4

Update won’t get called on scripts that are attached to inactive gameobjects.

5

I know. but even when I activate the GO again it doesnt run. It worked before but have no idea why it isnt now.

You can use gameObject.activeInHierarchy to check if it should be updating. As long as the component, the gameobject, and all its parents are active, it will be updated.
