need help with slider decrease value with volume audiosource

i hard stuck 3 days now with this code i want my slider value decrease with volume of audiosource i tryed to work it out but i think i don't understand syntax between code so my solution was to change SliderInstance.Value to 0.01f but all this fix do is jumps up and down according audiosources origin volume but i want do this slider max value should be 100 and after time decrease by 99,98,97,96 etc and music of audiosource also should decrease until you will not able to hear it i want visual to match with hearing

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class Music : MonoBehaviour
7. {
8.  
9.  
10.     // Start is called before the first frame update
11.     public AudioSource AudioSource; // Assign in editor/etc
12.     public float MusicVolume = 10f;
13.     public Slider SliderInstance;
14.  
15.     public float Age = 2f;
16.    
17.     void Start()
18.     {
19.         AudioSource.Play();
20.         SliderInstance.minValue = 0;
21.         SliderInstance.maxValue = 100;
22.         SliderInstance.wholeNumbers = true;
23.         SliderInstance.value = 100f;
24.     }
25.     void Update()
26.     {
27.         Age += Time.deltaTime;
28.         AudioSource.volume = .7f / (5.0f + Age / 1.0f);
29.         SliderInstance.value =  100f *Time.deltaTime;
30.         AudioSource.volume = SliderInstance.value;
31.  
32.     }
33.     public void UpdateVolume(float Volume)
34.     {
35.         MusicVolume = Volume;  
36.     }
37.    
38.  
39.    
40. }
41.

Has to be between 0 and 1.

 

okay but it does not decrease with age i want it to sync

 

Your current calculation will cause it to increase over time. Also dividing a number by 1 equals the original number its redundant.

It would be simpler to do something like.

Code (CSharp):

1. AudioSource.volume -= audioDecreaseValue * Time.deltaTime;
2. SliderInstance.value = AudioSource.volume;

Keep your silders min max at 0 and 1 respectively.

 

woooooow it worked so problem was when i messed around 0 and 1? next time i will respect that a little more i thought i can mess with whole numbers thank you a lot god bless u(if u believe so)
