Settings are managed by the Settings Service (GameService.Settings) and are saved to settings.json. Settings are manged with the Settings.SettingEntry<T> class and are contained within a Settings.SettingCollection. SettingCollection supports containing other SettingCollection allowing you to better organize your settings.

All types are technically supported as long as they are serializable. The following types will, however, provide the best experience:

  • bool
  • float
  • int
  • string
  • Any enum

Defining Settings

Settings can be defined at any time. Once defined, they are kept in settings.json if their value is different from the defined default.

The best time to define module settings is in the DefineSettings method. The settings parameter is the root SettingCollection associated with your module. You can add as many settings and collections as you would like within this collection.

protected override void DefineSettings(SettingCollection settings) {
_settingOnlyShowAtHighSpeeds = settings.DefineSetting("OnlyShowAtHighSpeeds", false, () => "Only Show at High Speeds", () => "Only show the speedometer if you're going at least 1/4 the max speed.");
_settingShowSpeedNumber = settings.DefineSetting("ShowSpeedNumber", false, () => "Show Speed Value", () => "Shows the speed (in approx. inches per second) above the speedometer.");
_appearanceSettings = settings.AddSubCollection("Appearance", true);
_settingShowWithSparkles = _appearanceSettings.DefineSetting("ShowWithSparkles", true, () => "Show Sparkles", () => "If enabled, sparkles will be shown on the speedometer.");
_settingSparkleCount = _appearanceSettings.DefineSetting("SparkleCount", 5, () => "Sparkle Count", () => "The number of sparkles to show on the speedometer if 'Show Sparkles' is enabled.");
_settingSparkleCount.SetRange(1, 10);
DefineSettings(string entryKey, T defaultValue, Func<string> displayNameFunc = null, Func<string> descriptionFunc = null)
  • entryKey is the unique name of the setting within the collection. Each setting within a SettingCollection must have a unique entryKey.
  • defaultValue is the default or initial value of the setting.
  • displayNameFunc is the friendly display name used when the setting is rendered within the UI. It is provided as a function which returns a string to ensure it is localization friendly.
  • descriptionFunc is the setting description which is shown when the mouse hovers over a rendered setting within the UI. It is provided as a function which returns a string to ensure it is localization friendly.

For internal settings managed manually by your module, you do not need to define displayNameFunc or descriptionFunc as they are only used when displayed within the UI by a SettingsView.

AddSubCollection(string collectionKey, bool renderInUi)
  • collectionKey is the unique name of the new sub collection within the collection. No different than the entryKey when defining settings.
  • renderInUi if true, the subcollection will automatically render itself when a parent collection is rendered. If false, the subcollection will be ignored if the parent collection is rendered to the UI.

Compliant Settings

Some settings, in context, need to be limited in some way when displayed in the UI.


int and float setting entries can set the allowed range for the value using SetRange(minValue, maxValue);. When the setting is rendered, the TrackBar control which allows changing the value will be limited to the range you've set with SetRange.


Settings that are automatically rendered can have their associated control disabled in the UI using SetDisabled(true);.

SetIncluded / SetExcluded

Allows you to limit the list of enums made available to a setting using SetIncluded(Enum1.Value1, Enum1.Value2, ...);.

Rendering Settings

Supported setting types (listed below) can be automatically rendered to a view. To do this, pass a SettingCollection in the constructor of a SettingsView.

var settingPanel = new ViewContainer() {
Size = new Point(200, 400),
Parent = ...
var settingsView = new SettingsView(this.Model.State.Settings);

'First Class' Types

Only some types support automatically generating controls to manage the setting. For instance, a bool setting can be automatically rendered to a checkbox control.


setting.DefineSetting("MinimizeToTray", true, () => "Minimize to tray when Guild Wars 2 Closes.", () => "...");

bool setting entry

float, int

setting.DefineSetting("CompassSize", 3, () => "Compass Size", () => "...");

numeric setting entry


setting.DefineSetting("Language", Language.English, () => "Application & API Language", () => "...")

enum setting entry
