24.     // Update is called once per frame
25.     void Update() {
26.    
27.         wybrany = PlayerPrefs.GetInt ("wybrany");
28.         Debug.Log (wybrany);
29.        
30.         for(int i=0;i<=5;i++)
31.         {
32.            
33.            
34.             if(wybrany==i)
35.             {
36.                 ColorBlock cb= buttons[i].colors;
37.                 cb.normalColor = new Color32 (189, 175, 175, 255);
38.                 buttons[i].colors=cb;
39.    
40.                 if(i!=5)
41.                 i++;
42.             }
43.            
44.             ColorBlock cb1= buttons[i].colors;
45.             cb1.normalColor = new Color32 (255, 255, 255, 255);
46.             buttons[i].colors=cb1;
47.  
48.         }
49.    
50.     }
51. }

 

Someone help me with the code?

 

which components are on your gameobject, an image and a button component ? or just a button component ?

try also to change

Code (CSharp):

1. buttons[i].targetGraphic.color

also it doesn't depend on your touches, because you have everything in your update method it's called every frame anyway

better would be a method that just is called ones and sets the colors to the buttons you want

 

In button script. Script for touch looks like that. So if player touches a button and He chooses the image ,button to change to make it clear that the object is selected. Here is a picture of how it all looks http://postimg.org/image/5r7d3gfm3/

Code (csharp):

1.  
2.    void Update()
3. {
4. for (var i = 0; i < Input.touchCount; ++i) {
5.             Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch (i).position);
6.          
7.             if (Input.GetTouch (i).phase == TouchPhase.Began) {
8.  
9.              
10.                 if (Physics.Raycast (ray, out hit))
11.                  
12.                     if(hit.collider.gameObject.tag=="car" )
13.                 {
14.                     if(kredki>=price&&carkupiony!=1)
15.                     {
16.                         car.GetComponent<Image> ().sprite = item1;
17.                         crayons=crayons-price;
18.                         PlayerPrefs.SetInt("car",1);     // buy images
19.                         PlayerPrefs.SetInt ("wybrany",0);  // Selecting the current background image to the game, "0" means car
20.                         PlayerPrefs.SetInt("CrayonsPoints",crayons);
21.  
22.                     }
23.                 if(carkupiony==1)
24.                     {
25.                         PlayerPrefs.SetInt ("wybrany",0);
26.              
27.                     }
28.                 }
29. }
