Save slider value at runtime, and reload latest value on launch

Questions & Answers
1

I have an application which has a ‘volume trigger’ whose sensitivity can be controlled via a slider.

I would like to configure it so that if a user changes the sensitivity and quits the application, the latest value is loaded in the application on launch.

So there are 2 steps,
1 - serializing and saving the slider value, overwriting any previous value

2 -loading this value when the application launches

Can any C# gurus help with some scripting pointers, tips suggestions?

You can use PlayerPrefs to store the value.

Each time the slider is changed, update the value in PlayerPrefs and the volume setting.

For example:

float sliderValue = 0.5f; //TODO: read value from slider
PlayerPrefs.SetFloat("volume", sliderValue);

When the game is launched, or each time you launch a new scene, you can use a function like Start to read a value from PlayerPrefs. Use that value to populate the slider and volume setting.

For example:

void Start() {
    float sliderValue = PlayerPrefs.GetFloat("volume", 0.5f); //second value is default
    //TODO: use sliderValue to set up the scene
}

You didn’t specify how you’re creating the slider, but most slider systems will allow you to easily get & set the current value of the slider.
