Game.UI.Editor.LoadAssetPanel

Assembly: Game
Namespace: Game.UI.Editor

Type: class

Base: EditorPanelBase

Summary:
LoadAssetPanel is an editor UI panel used to present a searchable list of assets to the user and allow them to pick one to load. It composes a SearchField, an ItemPicker (with favorites support), an ItemPickerFooter, and a row of buttons (Load and Cancel). The panel uses an AssetPickerAdapter to drive the UI widgets and reports the selected asset via a LoadCallback delegate that receives the asset's Hash128 guid. The "Load" button is disabled until an item is selected; the "Cancel" button invokes the provided close action.

Fields

  • public delegate void LoadCallback(Hash128 guid)
    Delegate type invoked when the user confirms a selection. Receives the selected asset's Hash128 guid.

  • private LoadCallback m_ConfirmCallback
    Holds the callback provided by the caller to be invoked when the user confirms (presses the "Load" button).

  • private AssetPickerAdapter m_Adapter
    Adapter instance that provides data and selection state to the SearchField, ItemPicker and footer widgets. It exposes the currently selected AssetItem via m_Adapter.selectedItem.

Properties

  • None (no public properties are defined on this class).

Constructors

  • public LoadAssetPanel(LocalizedString panelTitle, IEnumerable<AssetItem> items, LoadCallback onConfirm, Action onClose)
    Creates a new LoadAssetPanel instance.
  • panelTitle: localized title shown at the top of the panel.
  • items: collection of AssetItem entries to display in the picker.
  • onConfirm: LoadCallback invoked with the selected asset guid when the user confirms.
  • onClose: Action invoked when the user cancels/closes the panel. Behavior:
  • Initializes an AssetPickerAdapter with the provided items.
  • Builds the panel's child widgets:
    • SearchField wired to the adapter for filtering.
    • ItemPicker wired to the adapter with hasFavorites = true.
    • ItemPickerFooter wired to the adapter.
    • Button row with two buttons:
    • "Editor.LOAD": disabled while no item is selected, calls OnConfirm when pressed.
    • "Common.CANCEL": calls the provided onClose action.

Methods

  • private void OnConfirm()
    Invoked by the "Load" button. Calls the stored m_ConfirmCallback with the guid of the currently selected asset:
  • m_ConfirmCallback(m_Adapter.selectedItem.guid) Note: The "Load" button is disabled when m_Adapter.selectedItem is null, so this method assumes a non-null selectedItem when invoked.

Usage Example

// Example: creating and showing a LoadAssetPanel
IEnumerable<AssetItem> availableAssets = GetAllAssetsSomehow();
LocalizedString title = new LocalizedString("Editor.SELECT_ASSET");

var panel = new LoadAssetPanel(
    title,
    availableAssets,
    onConfirm: (Hash128 guid) =>
    {
        // Called when user selects an asset and presses Load
        LoadAssetByGuid(guid);
    },
    onClose: () =>
    {
        // Called when user cancels/closes the panel
        ClosePanel();
    }
);

// Add panel to your editor UI container (pseudo-code)
EditorUI.ShowPanel(panel);
