Create a new Unity project and import the NexPlayer™ Plugin.

In order to load the player Scene follow the path: 'Assets/NexPlayer/Scenes' and open 'NexPlayer raw video.unity' with double click. Test the playback selecting play button in the editor.

Load the 360 Scene available in 'Assets/NexPlayer/NexPlayer360/Scenes/NexPlayer360.unity'. Test the playback selecting play button in the editor.

Add the following scenes to the Unity build:

• Assets/NexPlayer/Scenes/ChooseMain.unity
• Assets/NexPlayer/Scenes/MainMenu.unity
• Assets/NexPlayer/Scenes/MainMenuVR.unity
• Assets/NexPlayer/Scenes/NexPlayer game objects.unity
• Assets/NexPlayer/Scenes/NexPlayer.unity

Switch to the desired platform.

Graphics APIs:

• Manually, select the compatible graphics APIs manually in "Player Settings" section of Unity for each platform.
• Automatically, if the helper component NexEditorHelper.cs is attached to any GameObject. It will include a graphics UI to auto detect any conflict regarding the graphics API, and it will promptly solve it.

Android platform:

• To allow any remote video select the true value for "Internet Access" option in the Unity player settings.

iOS platform:

• To view HTTP videos enable "Allow downloads over HTTP" option.

A quick and easy way to enable these settings is using the helper component (NexEditorHelper.cs).

Virtual Reality mode:

• Go to "Player Settings" --> "Other Settings" and select the desired VR mode (depends on the Unity version used). If "Oculus" is selected, remember to generate the OSIG file for the device and add it into 'Assets/Plugins/Android/Assets'.

An example of using NexPlayer™ can be found in the script NexPlayer.cs. It has to be attached to some game object that has a material and a texture. The URL and the text fields used to update the status can be personalized.

A custom implementation of NexPlayer™ can also be done manually:

void Start ()
{
    // Creation of the NexPlayer instance
    player = NexPlayerFactory.GetNexPlayer();
    // Register to the events of NexPlayer
    player.OnEvent += EventNotify;
    // Initialize NexPlayer with an URI
    player.Init(URL, true, false);
    // The coroutine needs to be started after the player is created an initialized
    StartCoroutine(player.CoroutineEndOfTheFame());
}

The update method of the player needs to be called at the Update callback of the MonoBehaviour object:

void Update()
{
    player.Update();
}

The previously used Action needs to be declared. It will provide a number of helpful callbacks. Properly assigning the texture to the material used by the game object should be done in the correct callback.

void EventNotify(NexPlayerEvent paramEvent, int param1, int param2)
{
    switch(paramEvent)
    {
        case NexPlayerEvent.NEXPLAYER_EVENT_TEXTURE_CHANGED:
            // It's important to change the texture of every Unity object that should
            display the video frame when this callback is called
            GetComponent<Renderer>().material.mainTexture = player.GetTexture (); break;
    }
}

Release the player using the ClosePlayback method and wait for the NEXPLAYER_EVENT_CLOSED callback:

public void ToogleQuit()
{
player.ClosePlayback();
}

void EventNotify(NexPlayerEvent paramEvent, int param1, int param2)
{
    switch (paramEvent)
    {
        case NexPlayerEvent.NEXPLAYER_EVENT_CLOSED:
        {
            Application.Quit();
        }
        break;
    }
}

The script NexPlayer360.cs provides the most important functionalities of a 360 viewer. It can be used as a reference for a custom integration.

To integrate the AutomaticGroundLeveler use the following code:

void Awake()
{
    agl = new AutomaticGroundLeveler();
}

void Update (){
    //Move the camera with a custom login
    //Stabilize the camera
    agl.AutomaticGroundLevelerStep(cameraToRotate.transform, latestAttitude, rotating);
}
