Scripting but kind of math question [UI Slider]

Hi all,
So im wondering because i have a slider bar where 1 = 100% of the slider bar and 0 = 0%
So i have script that calculates all objects in scene with tag ''points'', there could be 6 objects or even 350, any number of objects.
The problem is that i dont know how to make slider bar so it shows for example always full 100% even that there are 5 objects in scene.
Here my variables

Code (JavaScript):

1.  
2. var NumberOfPointsInStart: int = 0;
3. var CurrentPoints : int = 0;
4.  

first as the name says it calculates all the number of points in the scene at function start
Second in function start is = to NumberOfPointsInStart and shows current points
When you destroy point the number goes down in current points but NumberOfPointsInStart stays always same from begining till end.
So i have code that updates every frame for slidebar but i dont know how to make it NumberOfPointsInStart = to 100% of current points :? [and the problem is i could research in google but idk how to put this in simple short words]

Thanks for helping !

 

So you want the bar to start at 0% and increase to 100% as you destroy stuff?

Code (csharp):

1.  
2. (NumberOfPointsInStart - CurrentPoints) / NumberOfPointsInStart;
3.  

 

Hi there i want other way around start at 100% and when get destroyed get to 0

looks like this code isnt working i dont know why :/ i know when i make
.fillAmount = CurrentFireToDestroy / 100f;
then it shows for example when there is 21 objects it shows as 21% and when i destroy one it goes down so the bar is working

 

I made it took my calculator out played around a bit with sheet of paper and pen and i did it
This is what i wrote currentpoints/pointsatstart x 100 / 100

 

Code (JavaScript):

1. (CurrentPoints / StartPoints * 100f) / 100f;

If anyone needed

 

The 100's are redundant then. All you need is

Code (csharp):

1.  
2. CurrentPoints / StartPoints;
3.  

Edit: It occurs to me why you might have been running into issues. If both of those are int then the result is int which won't contain decimal information. So you'd want to cast each to float and make sure the result is a float as well

Code (csharp):

1.  
2. float percent = (float)CurrentPoints / (float)StartPoints;
3.  

 

Thanks for help
