• Modal dialog management.
• Common dialog boxes such as MessageBox and InputBox.

This library provides basic modal dialog managements on Unity-GUI. Modal dialog box works like a function which gets input argument, does work, and returns return value. When a modal dialog box shows, input of other windows under showing dialog box will be blocked.

// show up TestDialogBox with an arugmentvarhandle=UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");// waits for dialog to finish it's workyieldreturnStartCoroutine(handle.WaitForHide());// gets return value from dialogDebug.Log(handle.ReturnValue);

DialogBox should inherit UiDialog. When dialog box shows up, OnShow handler will be invoked with param is passed by ShowModalRoot. When work done and there is a return value, Hide method can be used.

//publicclassTestDialogBox:UiDialog{publicoverridevoidOnShow(objectparam){// gets an argument from callerMessage.text=(string)param;Input.text="";}publicvoidOnOkButtonClick(){// returns values to callerHide(Input.text);}}

It's quite simple to show modal dialog boxes but there are several ways for showing dialog box.

• ShowModalPrefab: Use the prefab dialog box. Whenever show up new dialog, dialog box will be instantiated.
• ShowModalTemplate: Use the template dialog box in the scene. Whenever show up new dialog, dialog box will be cloned.
• ShowModal<T>: Use a passed dialog box whose type is T.
• ShowModalRoot<T>: Use a named dialog box under Canvas/DialogBox in the scene.

For getting return value of it, there are two ways.

First one is using Hidden callback.

varhandle=UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");handle.Hidden+=(dlg,val)=>{Debug,Log(val);};

Second one is using coroutine. It's quite useful under modal chaining.

varhandle=UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");yieldreturnStartCoroutine(handle.WaitForHide());Debug.Log(handle.ReturnValue);

UiMessageBox.Show("This is a message question <b>box</b>",UiMessageBox.QuestionType.OkCancel, r =>{/* Callback */});

UiInputBox.Show("Please input your name:","Input", r =>{/* Callback */});
