Changing Emission Color in script

[DrYSG]

This the glow code when called makes the item glow(). But that is a one shot. I figured the Update should turn off the glow at the next update, but that is not happening.

using UnityEngine;
using System.Collections;

public class StoneScript : MonoBehaviour
{
    Color brighter;
    Color greenGrey;
    Material myMaterial;
    bool bright = false;

    // Use this for initialization
    void Start()
    {
        ColorUtility.TryParseHtmlString("#3E594CFF", out greenGrey);
        brighter = greenGrey * Mathf.LinearToGammaSpace(0.8f);
        myMaterial = GetComponent<Renderer>().material;
    }

    public void glow()
    {
        myMaterial.SetColor("_EmissionColor", brighter);
        bright = true;
    }

    // Update is called once per frame
    void Update()
    {
        if (bright)
        {
            bright = false;
            myMaterial.SetColor("_EmissionColor", greenGrey);
        }
    }
}

Seems like your code is correct. Where are you calling glow()? Maybe you are calling glow() every frame so bright keeps getting set to true?

Is the “if(bright)” conditional happening? Try putting a print statement in there to check.

I have tried a couple of things (including what you said).

1. I take out the if (bright) all twelve stones (connected to stoneScript) go bright immediately.

2. Glow is being called by a rotating object that points at one of the 12 items at a time. If I cut the framerate to 1fps, I can watch each one go one at a time, but then never turn off.

3. The object calling glow is doing the following:

   void Update()
   {
   RaycastHit hit;
   Vector3 origin = transform.position;
   Vector3 fwd = transform.TransformDirection(Vector3.forward);
   origin += fwd * (carLength / 2); // move sensor to front bumper
   bool hitTest = Physics.Raycast(origin, fwd, out hit);
   Debug.DrawRay(origin, fwd * hit.distance, Color.cyan, 0, true);
   if (!Dispatcher.me.ready) return;
   if (!Dispatcher.me.work) return;
   if (hitTest)
   {
   GameObject target = hit.collider.gameObject;
   StoneScript stone = target.GetComponent();
   results.hitDistance = hit.distance;
   results.hitID = target.name;
   stone.glow();
   }
   }
