public Material[] ShirtColorMat;

Renderer renderer;
int PantSaver;

void Start()
{
    renderer = this.GetComponent<Renderer>();
    PantSaver = PlayerPrefs.GetInt("Saver");
}

public void _000000()     // i use this on button 
{
    renderer.material = ShirtColorMat[0];
    
    Save();
}
 void Save()
{
    PlayerPrefs.SetInt("Saver", PantSaver);
}

thanks

Answer 1

You are not updating the PantSaver value.

It should probably rather be

public void _000000()
{
    PantSaver = 0;
    renderer.material = ShirtColorMat[PantSaver];
    
    Save();
}
 void Save()
{
    PlayerPrefs.SetInt("Saver", PantSaver);
}

In general a property might be of good use here:

private int _pantSaver;
private int PantSaver
{
    get => _pantSaver;
    set
    {
        _pantSaver = value;
        PlayerPrefs.SetInt("Saver", value);
        PlayerPrefs.Save();
        renderer.material = ShirtColorMat[value];
    }
}

This way everytime you assign a new value to PantSaver it is automatically saved and the renderer updated.

So then you would only need to do

public void _000000()
{
    PantSaver = 0;
}

Finally please rename _000000 to something more meaningful like eg ResetPant or something similar.

You might in Save() want to say PlayerPrefs.SetInt("Saver", ShirtColorMat[0]); instead. What you have in "PantSaver" is not a reference but a value . This means that with the above code you are currently first getting the value "Saver" and then setting the same value again.

The PlayerPrefs.SetInt 's first string parameter is the key you save it to and later can get it from.
