Unity Script Binding

Sample Unity Script Binding

This is a sample script that binds a function in Unity engine that is to be called from JavaScript. The interface used for the binding is exactly the same as in C#.

The first example shows how a manual binding is done.

#pragma strict
import Coherent.UI.Binding;

var m_View : CoherentUIView ;

// Use this for initialization
function Start ()
{
    m_View = GetComponent(typeof(CoherentUIView)) as CoherentUIView;
    //Listen for the ReadyForBindings event
    m_View.Listener.ReadyForBindings += HandleReadyForBindings;
}

function HandleReadyForBindings ( frameId:int,
                                    path:String,
                                    isMainFrame : boolean)
{
    if (isMainFrame)
    {
        /* Bind FunctionInUnity so that JavaScript can call it */
        Debug.Log("Ready for bindings..");
        m_View.View.BindCall("CallFunctionInUnity", this.FunctionInUnity);
    }
}

function FunctionInUnity()
{
    Debug.Log("SUCCESS! This function is called from Javascript!");
}

Here is another sample - the same code used to the the binding in BindingSample, but in UnityScript and using the automatic binding feature of CoherentUI.

#pragma strict
import Coherent.UI.Binding; // to use View.TriggerEvent with extra arguments

public class GameOptions {
    var Backend : String;
    var Width : String;
    var Height : String;
    var NetPort : String;

    function GameOptions(){
        this.Backend = "Unity3D";
        this.Width = "1024";
        this.Height = "768";
        this.NetPort = "17777";
    }

    function GameOptions(backend : String,
                            width : String,
                            height : String,
                            netPort : String) {
        this.Backend = backend;
        this.Width = width;
        this.Height = height;
        this.NetPort = netPort;
    }
}
private var m_View : CoherentUIView;
private var m_GameOptions;

function Start () {
    m_View = GetComponent(typeof(CoherentUIView)) as CoherentUIView;

    m_GameOptions =  new GameOptions("Unity3D", "1024", "768", "17777");
}

@Coherent.UI.CoherentMethod ("ApplyOptions", false)
function ApplyOptions(options : GameOptions)
{
    m_View.View.TriggerEvent("gameConsole:Trace", options);
}

@Coherent.UI.CoherentMethod("GetLatency")
function GetNetworkLatency()
{
    // not actual latency :)
    return 100;
}

@Coherent.UI.CoherentMethod("GetGameTime")
function GetGameTime()
{
    // not actual time :)
    return 20;
}

@Coherent.UI.CoherentMethod("ViewReady", true)
function ViewReady()
{
    // show the options
    m_View.View.TriggerEvent("OpenOptions", m_GameOptions);
}
