Dynamic Sized Sliced Sprite BG Based On Text?

[Majicpanda]

Is it possible to dynamically size a sprite that you have a label on? Ideally I would like to use a sliced sprite that adjusts itself to a set width but scales vertically based on the height the label is taking up. I think UITooltip does this somehow but is there any tutorial on achieving this? Font size etc I would think have to be considered along with lines of text.

Thanks.

I do this by getting the Y scale of the text then multiplying that by the number of lines I have and adding that to the Y scale of the background/sliced sprite. The way I get the number of lines is using RelativeSize (UILabel), the Y seems to always be a whole number while correlates with the number of lines (for a fixed width UILabel).

I did this script, but didn't work, the log says the sprite is moving, but nothing happens.

1. public class SpriteMatchTextLenght : MonoBehaviour
2. {
3.    public UILabel textToMatch;
4.    public UISprite slicedTexture;
5.      
6.    void OnGUI ()
7.    {
8.       Vector3 textScale = textToMatch.transform.localScale;
9.       Vector3 textRelSize = textToMatch.relativeSize;
10.       Vector3 slicedScale = slicedTexture.transform.localScale;
11.      
12.       slicedScale.y = (textScale.y*textRelSize.y);
13.      
14.       slicedTexture.transform.localScale = slicedScale;
15.      
16.       Debug.Log(slicedScale.y);
17.    }
18. }
19.  
20.

Select the panel managing your sprite and uncheck the "static" checkbox.

Thanks Aren, but it wasn't that.

I was missing adding the actual Y size of the sliced sprite, so I create a public yOffset for this and I can preview the exact size I need.

1. public class SpriteMatchTextLenght : MonoBehaviour
2. {
3.    public UILabel textToMatch;
4.    public UISprite slicedTexture;
5.    public float yOffset;//273
6.      
7.    void OnGUI ()
8.    {
9.       Vector3 textScale = textToMatch.transform.localScale;
10.       Vector3 textRelSize = textToMatch.relativeSize;
11.       Vector3 slicedScale = slicedTexture.transform.localScale;
12.      
13.       slicedScale.y = (textScale.y*textRelSize.y)+yOffset;
14.      
15.       slicedTexture.transform.localScale = slicedScale;
16.      
17.       Debug.Log(slicedScale.y);
18.    }
19. }
