Slider snap to interval

Question

Is there anyway to make set values for a slider that when slid it will snap to those values? For example say I have a slider with a value of 0 to 10. Can I have 10 values in-between so when you slide it, it snaps to 1 then 2 then 3, ect. Instead of being able to freely slide it to whatever value you want.

You could cast the result of .Slider to an int, which would lock it to integers. Or you could go more fancy and write your own locking code -

int result = GUI.Slider(blah);

if ( result < 10 ) result = 0; else if ( result < 20 ) result = 10;

etc..

Here's a versatile piece of code to round to any interval. You can include this in a function that gets called when the slider's value is changed.

 float value = slider.value;
 float interval = 0.2f; //any interval you want to round to
 value = Mathf.Round(value / interval) * interval;
 slider.value = value;

this is the correct answer, made a class and simply add this to your Slider UI:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class SliderValueSnap : MonoBehaviour
 {
     public float snapInterval = 5; //any interval you want to round to
     private Slider sliderUI;
 
     void Start()
     {
         sliderUI.onValueChanged.AddListener(delegate { ShowSliderValue(); });
         ShowSliderValue();
     }
 
     public void ShowSliderValue()
     {
         float value = sliderUI.value;
         value = Mathf.Round(value / snapInterval) * snapInterval;
         sliderUI.value = value;
     }
 }
