ETGameSettings

This is a persistent (DontDestroyOnLoad) object which sets, loads and manages the game settings. This includes: volume levels, fov, key bindings, etc.

At the start of the game (ideally the menu scene), the component will load each setting in from the PlayerPrefs. These settings can then be accessed by components (e.g. the camera will read the FOV setting and assign it upon initialization, as well as whenever that value changes).

For a full list of settings, check out the ETGameSettings script.

Scripting

Accessing a setting value can be done like so:

ETGameSettings.Instance.MusicVolume.Value;

To change a setting (in a settings screen for example), call the setting's ChangeValue(T) function.

ETGameSettings.Instance.MasterVolume.ChangeValue(0.5f);

Each setting is represented by a generic Setting class. There are 4 supported data types for these settings: int, float, bool, string. Each setting also has a default value and PlayerPrefs key, which is assigned upon its initialization, as well as an OnUpdatedValue(T) event, which you can connect to in order to apply changes made.

For example, if you wanted the camera's field of view to update whenever the setting is changed, you could implement the following:

void OnEnable ()
{
    inputManager.OnRightMouseButton += OnRightMouseButtonInput;
    ETGameSettings.Instance.FieldOfView.OnUpdatedValue += OnFieldOfViewSettingChanged;
}

void OnDisable ()
{
    inputManager.OnRightMouseButton -= OnRightMouseButtonInput;
    ETGameSettings.Instance.FieldOfView.OnUpdatedValue -= OnFieldOfViewSettingChanged;
}

void OnFieldOfViewSettingChanged (float newFOV)
{
    cam.fieldOfView = newFOV;
}
