MenuOptionBase

Class
Namespace: SwiftlyS2.Core.Menus.OptionsBase · Assembly: SwiftlyS2.CS2.dll
public abstract class MenuOptionBase : IMenuOption, IDisposable
Inherits object

Provides a base implementation for menu options with event-driven behavior.

Constructors

MenuOptionBase()

Creates an instance of MenuOptionBase.

protected MenuOptionBase()

Using the parameterless constructor will not enable dynamic text updating features. Derived classes should override the Int32) method to implement custom text style changes.

MenuOptionBase(int, int)

Creates an instance of MenuOptionBase with dynamic text updating capabilities.

protected MenuOptionBase(int updateIntervalMs, int pauseIntervalMs)
Parameters
  • updateIntervalMsintThe interval in milliseconds between text updates.
  • pauseIntervalMsintThe pause duration in milliseconds before starting the next text update cycle.

Values less than 1/64f*1000 milliseconds (approximately 15.6ms) are meaningless, as the refresh rate would be higher than the game's frame interval. Both parameters will be automatically clamped to this minimum value.

Properties

BindingText

Gets or sets a function that dynamically provides the text content for this menu option.

public Func<string?>? BindingText { get; set; }
Property Value

When this property is set to a non-null function, the Text property's getter will invoke it to retrieve the current text value on each access. This enables automatic tracking of external string sources. The function can return null to indicate that it wants to fall back to the static Text value, or return an empty string to display nothing. Setting this property to null will revert to using only the static Text value stored in the backing field. Example usage: string myText = "Hello"; option.BindingText = () => myText; myText = "World"; // option.Text now returns "World" // Return null to use fallback Text option.BindingText = () => condition ? playerName : null;

CloseAfterClick

Gets or sets a value indicating whether the menu should be closed after handling the click.

public bool CloseAfterClick { get; init; }
Property Value

Comment

Gets or sets the comment content displayed for this menu option.

public string Comment { get; set; }
Property Value

This is a global property. Changing it will affect what all players see.

Enabled

Gets or sets a value indicating whether this option can be interacted with.

public bool Enabled { get; set; }
Property Value

This is a global property. Changing it will affect what all players see.

LineCount

Gets the number of lines this option requests to occupy in the menu.

public virtual int LineCount { get; }
Property Value

MaxWidth

The maximum display width for menu option text in relative units.

public float MaxWidth { get; set; }
Property Value

Menu

Gets or sets the menu that this option belongs to.

public IMenuAPI? Menu { get; }
Property Value

This property will be null until the option is added to a menu via IMenuOption). When implementing custom menu options, avoid accessing this property in the constructor as it will not be set yet.

PlaySound

Gets or sets a value indicating whether a sound should play when this option is selected.

public bool PlaySound { get; set; }
Property Value

Tag

Gets or sets an object that contains data about this option.

public object? Tag { get; set; }
Property Value

Text

Gets or sets the text content displayed for this menu option.

public string Text { get; set; }
Property Value

This is a global property. Changing it will affect what all players see. When BindingText is set to a non-null function, the getter will invoke that function to retrieve the current text value dynamically. If the function returns null, it falls back to this property's static value. Otherwise, it returns the static value stored in the backing field. Setting this property directly will update the static fallback value without clearing any BindingText binding. This allows BindingText and static text to coexist, with BindingText taking priority. The function is allowed to return an empty string, which will be displayed as-is.

TextSize

Gets or sets the text size for this option.

public MenuOptionTextSize TextSize { get; set; }
Property Value

TextStyle

Gets or sets the text overflow style for this option.

public MenuOptionTextStyle TextStyle { get; set; }
Property Value

Visible

Gets or sets a value indicating whether this option is visible in the menu.

public bool Visible { get; set; }
Property Value

This is a global property. Changing it will affect what all players see.

Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public virtual void Dispose()

~MenuOptionBase()

protected ~MenuOptionBase()

GetDisplayText(IPlayer, int)

Gets the display text for this option as it should appear to the specified player.

public virtual string GetDisplayText(IPlayer player, int displayLine = 0)
Parameters
  • playerIPlayerThe player requesting the display text.
  • displayLineintoptionalThe display line index of the option.
Returns
The formatted display text for the option.

When a menu option occupies multiple lines, MenuAPI may only need to display a specific line of that option. When LineCount=1 : The displayLine parameter is not needed; return the HTML-formatted string directly. When LineCount>=2 : Check the displayLine parameter: displayLine=0 : Return all content displayLine=1 : Return only the first line content displayLine=2 : Return only the second line content And so on... Note: MenuAPI ensures that the displayLine parameter will not exceed the option's LineCount .

GetEnabled(IPlayer)

Determines whether this option is enabled for the specified player.

public virtual bool GetEnabled(IPlayer player)
Parameters
  • playerIPlayerThe player to check enabled state for.
Returns
True if the option is enabled for the player; otherwise, false.

GetVisible(IPlayer)

Determines whether this option is visible to the specified player.

public virtual bool GetVisible(IPlayer player)
Parameters
  • playerIPlayerThe player to check visibility for.
Returns
True if the option is visible to the player; otherwise, false.

IsClickTaskCompleted(IPlayer)

Determines whether the click task for the specified player is completed.

public virtual bool IsClickTaskCompleted(IPlayer player)
Parameters
Returns
True if the click task is completed; otherwise, false.

OnClickAsync(IPlayer)

Handles the click action for this option.

public virtual ValueTask OnClickAsync(IPlayer player)
Parameters
  • playerIPlayerThe player who clicked the option.
Returns
A task that represents the asynchronous operation.

OnValidatingAsync(IPlayer)

Validates whether the specified player can interact with this option.

public virtual ValueTask<bool> OnValidatingAsync(IPlayer player)
Parameters
  • playerIPlayerThe player to validate.
Returns
A task that represents the asynchronous operation. The task result is true if validation succeeds; otherwise, false.

PauseTextAnimation()

public virtual void SetEnabled(IPlayer player, bool enabled)
Parameters
  • playerIPlayerThe player to set enabled state for.
  • enabledboolTrue to enable the option for the player; false to disable it.

The per-player enabled state has lower priority than the global Enabled property.

SetVisible(IPlayer, bool)

Sets the visibility of this option for a specific player.

public virtual void SetVisible(IPlayer player, bool visible)
Parameters
  • playerIPlayerThe player to set visibility for.
  • visibleboolTrue to make the option visible to the player; false to hide it.
