With this asset you can create modal dialogs in Unity 5 easily. The dialogs are based on the new Unity UI system and are highly customizable.

You can see the asset in action in this youtube video:

Getting started

When you added the package to your scene the first thing you need to show modal dialogs is the ModalDialogManager. Add it like that:

After that you need to add a Unity UI canvas:

Select the Canvas and then add the modal dialog from the UI-Contextmenu:

To open a modal dialog for example by a button-click, you can use this script, which is also included in the package:

using UnityEngine; using System.Collections; using UnityEngine.UI; public class BtnOpenModalDialog : MonoBehaviour { // Use this for initialization void Awake() { ModalDialogManager.Instance.DialogClosing += Instance_DialogClosing; ModalDialogManager.Instance.DialogClosed += Instance_DialogClosed; } void Instance_DialogClosed(object sender, Assets.UIModalDialog.Scripts.DialogClosedEventArgs e) { Debug.Log("Dialog " + e.DialogName + " is closed by button " + e.CloseButton.name); } void Instance_DialogClosing(object sender, Assets.UIModalDialog.Scripts.DialogClosingEventArgs e) { if (e.CloseButton.name == "NoButton") { // Access components of the dialog before closing Text errorText = e.DialogPanel.FindChild("ErrorText").GetComponent<Text>(); errorText.text = "Can't close dialog, error occured!"; e.Cancel = true; } } public void ShowDialog() { ModalDialogManager.Instance.ShowDialog(); } }

In this sample the dialogs is prevented from being closed when pressing the No-Button.

Another sample-scene is the UILoginDialog. The prefab added to the canvas is the LoginDialog-prefab.

The code for opening the Login dialog is:

using System; using UnityEngine; using System.Collections; using UnityEngine.UI; public class BtnOpenLoginDialog : MonoBehaviour { // Use this for initialization void Awake() { ModalDialogManager.Instance.DialogOpened += Instance_DialogOpened; ModalDialogManager.Instance.DialogClosing += Instance_DialogClosing; ModalDialogManager.Instance.DialogClosed += Instance_DialogClosed; } void Instance_DialogOpened(object sender, Assets.UIModalDialog.Scripts.DialogEventArgs e) { LoginCallback loginCallBack = e.DialogPanel.GetComponent<LoginCallback>(); loginCallBack.ClearInput(); } void Instance_DialogClosed(object sender, Assets.UIModalDialog.Scripts.DialogClosedEventArgs e) { if (e.CloseButton.name == "LoginButton") { Debug.Log("Ok, Login successfull"); } } void Instance_DialogClosing(object sender, Assets.UIModalDialog.Scripts.DialogClosingEventArgs e) { if (e.CloseButton.name == "LoginButton") { // Access Login callback scripton Login LoginCallback loginCallback = e.DialogPanel.GetComponent<LoginCallback>(); loginCallback.ClearErrors(); if(String.IsNullOrEmpty(loginCallback.GetUsername())) { loginCallback.SetErrorUsername("Please enter a username"); } if (String.IsNullOrEmpty(loginCallback.GetPassword())) { loginCallback.SetErrorPassword("Please enter a password"); } e.Cancel = loginCallback.HasError; } } public void ShowDialog() { ModalDialogManager.Instance.ShowDialog(); } }

With the attached LoginCallback-script you can initiaze the Logindialog on DialogOpened method (C# eventhandler) and react on input when submitting in the method DialogClosing.

But that’s not all. The modal dialog is highly customizable, you can see it in the UISocialDialog scene in which a social overlay for subscribing to a social community like youtube is displayed:

Here is the code for displaying this overlay after a special number of seconds:

using UnityEngine; using System.Collections; public class OpenSocialTimer : MonoBehaviour { public float TimeToOpen = 2; // Use this for initialization void Awake() { Invoke("ShowDialog", TimeToOpen); ModalDialogManager.Instance.DialogClosed += Instance_DialogClosed; } void Instance_DialogClosed(object sender, Assets.UIModalDialog.Scripts.DialogClosedEventArgs e) { if (e.CloseButton.name == "SubscribeButton") { Application.OpenURL("http://www.youtube.com/subscription_center?add_user=jayanamgames"); } } public void ShowDialog() { ModalDialogManager.Instance.ShowDialog(); } }
