# MessageBox - Async Modal Dialogs Built on UniTask for non-blocking async operations with automatic object pooling. ## When to Use - Confirmation dialogs (Yes/No, OK/Cancel) - Information prompts (OK only) - Awaiting user decisions in gameplay ## API ### Show Method ```csharp public static UniTask<bool> Show( string title, string content, string ok = "OK", string no = "Cancel" ) ``` Returns `true` for confirm, `false` for cancel. ### Management - `MessageBox.CloseAll()` - Dismiss all active dialogs (for scene transitions) - `MessageBox.Dispose()` - Release all pooled instances (app shutdown) - `MessageBox.ActiveCount` - Currently displayed dialogs - `MessageBox.PooledCount` - Cached instances in pool ## Patterns ### Confirmation Dialog ```csharp bool confirmed = await MessageBox.Show( "Delete Item", "Are you sure you want to delete this item?", ok: "Delete", no: "Cancel" ); if (confirmed) { DeleteItem(); } ``` ### Custom Button Text ```csharp bool saved = await MessageBox.Show( "Save Changes", "Keep your changes?", ok: "Save", no: "Discard" ); ``` ### Single Button (Notification) ```csharp // Pass null or empty string to hide cancel button await MessageBox.Show( "Success", "Operation completed!", ok: "OK", no: null ); ``` ### Clean Up Before Scene Change ```csharp MessageBox.CloseAll(); SceneManager.LoadScene("NextScene"); ``` ## Common Mistakes - Forgetting to await (dialog shows but code continues immediately) - Not handling both true/false return values - Not calling CloseAll() before scene transitions
