Scroll View Question

[Magic Frame]

Hi,

I'm creating a Scroll View, I was wondering how to make each scroll bar graph view to present a different, alternating between one color and another color, leave a picture for better understanding.

Since you're the one who's adding items to the scroll view, nothing is preventing you from having a background sprite on your entries and changing its color when you add new entries.

If I get that, but as I can know when it comes one color or another?

[ArenMook]

If (number of transform.childCount is even), use one color.
else, use another color.

Hi Aren, thanks for reply, I'm trying and I can not get it to work, when I access the children have only the last note, do not tell me what the 1,2,3,4 .... any suggestions, leave the code

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class BarGraphics : MonoBehaviour
5. {
6.         public int childNumber;
7.         // Use this for initialization
8.  
9.         void Start ()
10.        
11.        
12.         {
13.        
14.  
15.  
16.  
17.         }
18.        
19.         // Update is called once per frame
20.         void Update () {
21.  
22.  
23.                 childNumber = GameObject.Find("Gridplayer").transform.childCount % 2;
24.  
25.  
26.                 if ( childNumber ==0)
27.                 {
28.  
29.                         //Is Odd!!!
30.  
31.  
32.  
33.                 }else
34.                 {
35.  
36.  
37.                         //Is Even!!!
38.  
39.  
40.                 }
41.  
42.  
43.  
44.  
45.        
46.         }
47. }

Never use GameObject.Find. It's very, very slow... and using it inside Update() -- which happens every frame -- is even worse.

Assuming this script of yours is attached to a row component, checking for the number of children in the update isn't the right place. You need to do it wherever you add the children. If you can't do it there, then do it once inside Start(). And instead of checking the total child count, you'd want to:

1. for (int i = 0; i < transform.parent.childCount; ++i)
2. {
3.     if (transform.parent.GetChild(i) == transform)
4.     {
5.          // here you'd do (i % 2)
6.         break;
7.     }
8. }
