Progresss bar at zero still shows sprite

[kittikun]

Hi,

It doesn't seem possible to have a "true" 0% with the progress bar since the sprite is still showing. You can see the picture taken from "Example 0 - Control Widgets"

Is there any workaround this ?

Thank you

Well, you could do it by code.
Something like this

1. if(bar.value <= 0)
2. {
3.    // deactivate sprite
4. }

Yes, I know..

I guess this was more like a feature request, it would have been nice to have a checkbox for this

If you want to use Spliced sprite as progress indicator (with direct cuts), you actually might want three filled progress bars (UISprites) that create a one bar. It requires some extra work (you need three sprites instead of one, and you cannot use texture compression for the atlas), but it is doable

1. public static void SetValueForThreePartBar(UISprite[] parts, float value)
2.         {
3.                 int totalWidth = parts[0].width + parts[1].width + parts[2].width;
4.                 int valueWidth = Mathf.RoundToInt(value * totalWidth);
5.                 if (valueWidth > totalWidth)
6.                 {
7.                         valueWidth = totalWidth;
8.                 }
9.  
10.                 if (valueWidth < 1)
11.                 {
12.                         // Don't show anything
13.                         parts[0].fillAmount = 0.0f;
14.                         parts[1].fillAmount = 0.0f;
15.                         parts[2].fillAmount = 0.0f;
16.                 }
17.                 else if (valueWidth <= parts[0].width)
18.                 {
19.                         // Show only first part
20.                         parts[0].fillAmount = (float)(valueWidth) / (float)parts[0].width;
21.                         parts[1].fillAmount = 0.0f;
22.                         parts[2].fillAmount = 0.0f;
23.                 }
24.                 else if (valueWidth <= (parts[0].width + parts[1].width))
25.                 {
26.                         // Show first and second part
27.                         parts[0].fillAmount = 1.0f;
28.                         parts[1].fillAmount = (float)(valueWidth - parts[0].width) / (float)(parts[1].width);
29.                         parts[2].fillAmount = 0.0f;
30.                 }
31.                 else
32.                 {
33.                         // Show all three parts
34.                         parts[0].fillAmount = 1.0f;
35.                         parts[1].fillAmount = 1.0f;
36.                         parts[2].fillAmount = (float)(valueWidth - parts[0].width - parts[1].width) / (float)(parts[2].width);
37.                 }
38.         }
