I think having it in a function that gets{} the values before switching scene is the correct way to do it rather than having them all in Update(). For example on slider you don't need that update that often, just takes up unnecessary memory and your only moving over the values on switching scene's?

I'm trying to do this for a toggle but I haven't been able to figure out what I'm doing wrong all day.

It just keeps outputting true if it's toggled on or not.

When i switch from my main menu to level 1 the volume in level 1 switches the audio to 0, 5 and on the main menu o selected 0, 2

I'm getting a compiler error. - Heres my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MainthemeScript : MonoBehaviour
{
// Start is called before the first frame update
public AudioSource AudioSource;

public Slider volumeSlider;

public float musicVolume = 1f;


void start()
{
AudioSource.volume = musicVolume;
musicVolume =
AudioSource.volume = musicVolume;
volumeSlider.value = musicVolume;
}

// Update is called once per frame
void Update()
{
AudioSource.volume = musicVolume;
PlayerPrefs.Setfloat("volume", musicVolume)
}
public void updateVolume (float volume)
{
musicVolume = volume;
}
}

You can also make real variables that saves between scenes by using static before public in your variable, but if you restart the game it resets tho.
EX:
static public testVariable;

do you have to declare the volume variable some where first?

[dark_terion]

at first it didn't work for me but I changed the float to a static float and it worked (I'm using this for FOV)

[combatmedic]

YEEEEs finally i found the right thing ! Thanks

Let's say i have a slider on scene1, and I don't have it on scene2. I just need the slider value to use it on scene2. What would i do?

[quantummobilegames]

It works perfectly when I test it in unity. but when I export my project for android it doesn't save volume slider, do you have any idea what is going wrong?

[nrlafiefy]

my audio source didn't appear . why?? this is my script ...
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MusicPlay : MonoBehaviour
{
private AudioSource AudioSource;

public Slider volumeSlide;

private float MusicVolume = 1f;

private void Start()
{
AudioSource.Play();
MusicVolume =
AudioSource.volume = MusicVolume;
volumeSlide.value = MusicVolume;
}



// Update is called once per frame
private void Update()
{
AudioSource.volume = MusicVolume;
PlayerPrefs.SetFloat("volume", MusicVolume);
}

public void Volumeupdater(float volume)
{
MusicVolume = volume;
}

public void MusicReset()
{

AudioSource.volume = 1;
volumeSlide.value = 1;
}

}

[pillemarisken]

Thanks for the tutorial! I'm getting this error though: "error CS0120: An object reference is required for the non-static field, method, or property 'AudioSource.Play()'"
