Application.ExternalCall

파라미터

설명

Calls a function in the web page that contains the WebGL Player.

ExternalCall calls functionName in the web page containing the WebGL player, passing the given arguments to it. Supported argument types are the primitive types (string, int, float, string) and arrays of such types. Any other objects are converted to string using ToString and passed as strings.

The function is non-blocking; ExternalCall immediately returns without waiting for the function that was called to complete.

The number of passed arguments can be varying:

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    void Example()
    {
        // Calls MyFunction1 in the web page with no arguments
        Application.ExternalCall("MyFunction1");
        // Calls MyFunction2 in the web page with a string
        Application.ExternalCall("MyFunction2", "Hello from Unity!");
        // Calls MyFunction3 in the web page with several arguments of different types
        Application.ExternalCall("MyFunction3", "one", 2, 3.0F);
    }
}

The functions to be called are declared in the HTML page using standard syntax, for example:

// This should be contained in the host page in the appropriate <script> element.
// Using the above call from Unity, this will receive
// "Hello from Unity!" as the argument.
function MyFunction2( arg )
{
    alert( arg );
}
