Luna UI Documentation

MainMenuView<TSaveData, TSaveMetadata> is an abstract UIViewComponent that wires up Continue / Load / New Game / Settings / Credits / Quit buttons. Continue and Load are auto-enabled based on whether a save exists, queried through the GameSave manager you provide.

Main Menu

Setup

Build the UXML with these button names (the view does Q<Button>(...) lookups):
- ButtonContinue
- ButtonLoad
- ButtonNewGame
- ButtonCredits
- ButtonSettings
- ButtonQuit
Subclass MainMenuView<TSaveData, TSaveMetadata> for your save types and implement GetSaveManager() plus the six OnButton...Clicked abstracts.
Wire the GameSaveManager by returning your concrete manager from GetSaveManager().

csharp

public class MyMainMenuView : MainMenuView<MyGameSaveData, MyGameSaveMetadata>
{
    [SerializeField] private MyGameSaveManager _saveManager;

    protected override GameSaveManager<MyGameSaveData, MyGameSaveMetadata> GetSaveManager()
        => _saveManager;

    protected override void OnButtonContinueClicked()
        => _saveManager.LoadFromSlot(LastSaveSlot, /* loadScene */ true);

    protected override void OnButtonLoadClicked()       => OpenLoadView();
    protected override void OnButtonNewGameClicked()    => StartNewGame();
    protected override void OnButtonCreditsClicked()    => OpenCreditsView();
    protected override void OnButtonSettingsClicked()   => OpenSettingsView();
    protected override void OnButtonQuitClicked()       => Application.Quit();
}

API

Type signature:

csharp

namespace CupkekGames.Systems.UI;

public abstract class MainMenuView<TSaveData, TSaveMetadata> : UIViewComponent
    where TSaveData : IGameSaveData, IData, new()
    where TSaveMetadata : GameSaveMetadata

Properties

Property	Type	Description
`GameSaveManager`	`GameSaveManager<TSaveData, TSaveMetadata>`	The manager returned from `GetSaveManager()`.
`LastSaveMetadata`	`TSaveMetadata`	Metadata for the most-recent save (null if none).
`LastSaveSlot`	`int`	Slot index of the most-recent save.

Protected fields

_buttonContinue, _buttonLoad, _buttonNewGame, _buttonCredits, _buttonSettings, _buttonQuit — the resolved Button instances. Available after Awake().

Methods (abstract — you implement)

Method	Called when
`GetSaveManager()`	Once during `Awake()` to fetch your `GameSaveManager`.
`OnButtonContinueClicked()`	Continue button clicked.
`OnButtonLoadClicked()`	Load button clicked.
`OnButtonNewGameClicked()`	New Game button clicked.
`OnButtonCreditsClicked()`	Credits button clicked.
`OnButtonSettingsClicked()`	Settings button clicked.
`OnButtonQuitClicked()`	Quit button clicked.

Methods (virtual — override to extend)

OnEnable() / OnDisable() — wire/unwire button handlers and set initial focus. If you override, call base.OnEnable() / base.OnDisable().

Behaviour

When the view awakens, GetSaveManager().GetLastMetadata() is called once. The result decides:

Save exists: _focusName = "ButtonContinue", Continue + Load enabled, Continue gets initial focus.
No save: _focusName = "ButtonNewGame", Continue + Load disabled, New Game gets initial focus.
