Question by spiningit · Jul 08, 2016 at 12:19 PM · arraycolordatabasemysqlcontains

Get value from array in unity: debug works, value's changing, but color not changing

I want to call some values in array from mysql through a UI-Button. If the array contains strings equal to button's name, the button will pick values from the array. This value ( 0 & 1) will be translated into slider's value which is child of the button and it will change its color accordingly. if the slider value = 1, button color = green, if 0 = red.

The problem is i couldn't change the button color. Changing the value works, debug works too. This should be very simple, but i don't know why it doesn't work. This is the script attached in the button:

 public string[] data;
 
 void Start () { 
         StartCoroutine (loadStart ());
     }
 
     public IEnumerator loadStart (){
         yield return new WaitForEndOfFrame ();
 
         WWW sliderData = new WWW ("localhost/unitypb/slider.php");
         //wait until download finish
         yield return sliderData;
 
         //get data as text
         string sliderString = sliderData.text;
         //print (verantString);
         data = sliderString.Split (';');
 
         foreach (string x in data) {
             if (x.Contains (this.gameObject.name + "-KW" + KWtext.text)) {
                 int index = Array.IndexOf (data, x);

                 int savedValue = Convert.ToInt32 (GetDataValue (data [index], "Value:"));
                 this.GetComponentInChildren <Slider> ().value = savedValue;
 
                 if (this.GetComponentInChildren <Slider> ().value == 1) {
                     this.GetComponent <Image> ().color = Color.green;
                 }
 
                 if (this.GetComponentInChildren <Slider> ().value == 0) {
                     this.GetComponent <Image> ().color = Color.red;
                 }
 
                 Debug.Log (Convert.ToString (this.gameObject.name + "-KW" + KWtext.text));
             } else if (!x.Contains (this.gameObject.name + "-KW" + KWtext.text)) {          
                 this.GetComponent <Image> ().color = Color.white;
                 Debug.Log ("not available");
             } 
         }
     }
 
 public string GetDataValue (string data, string index) {
         string value = data.Substring (data.IndexOf(index)+index.Length);
         if(value.Contains("|")) 
             value = value.Remove (value.IndexOf ("|"));
         return value;
     }

However, if I remove this line the script would run just fine. But I would need it for other similar functions so i can't remove it.

 else if (!x.Contains (this.gameObject.name + "-KW" + KWtext.text)) {
                     this.GetComponent <Image> ().color = Color.white;
                     Debug.Log ("not available");
                 }
