DSE Parse Unity sample project with extendable UI.

I am assuming you already have a Facebook Application with iOS, Android and Canvas configured, as well as a Parse application with your Facebook Application credentials set up.

1. In Unity, configure the Facebook Settings with your App Name, and your App Id.
2. Open Scene, and on the Hierarchy Viewer, select Parse Initializer. Set your Parse Application ID and Dotnet Key
3. Save, run on the Editor, export to Android, iOS or Web and test away!

Open ParseTestBehavior.cs and look for void OnGUI(). This is the default method Unity uses to Draw it's basic UI. There are three sections on this project's UI: Login, Parse and Javascript. You will mostly work with Login and Parse. Each of these has a special method where their UI is encapsulated, these are called RenderLogin() and RenderParse. Go and take a look.

Let's assume you want to add a New Awesome Sample under RenderParse. At the end of this method, you could add the following:

private void RenderParse() {
    GUILayout.BeginHorizontal();
    if (Button ("My New Awesome Sample")) {
        MyNewAwesomeSample();
    }
    GUILayout.EndHoriziontal();
}

Then, you would have to create a new method called MyNewAwesomeSample:

private void MyNewAwesomeSample() {
    Debug.Log("Hello World!");
}

Run. You should see your new Button created on the UI, and when clicking / tapping on it, you will get a Log saying Hello World!
