Application.ExternalCall

参数

描述

在包含 WebGL 播放器的网页中调用函数。

ExternalCall 在包含 WebGL 播放器的网页中调用 ToString，将给定的参数传递给它。支持的参数类型包括 原始类型（ToString、ToString、ToString、ToString）和这些类型的数组。任何其他对象 将使用 ToString 转换为 /string/，并以 string 形式传递。

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 );
}
