异常:为WebGL生成时,生成WebGL播放器失败

unity-webgl unity3d c# javascript

Muhammad Faizan Khan · 技术社区 · 6 年前

margeInto(LibraryManager.library,{

    GameObjectHasClicked : function (str){
        window.alert(Pointer_stringify(str));
    },
        Hello: function (){
        window.alert(Pointer_stringify(str));
    },


});

using System.Runtime.InteropServices;
using UnityEngine;

public class SendInfoToBrowserJS : MonoBehaviour {

    [DllImport("__Internal")]
    private static extern void GameObjectHasClicked(string pos);

    [DllImport("__Internal")]
    private static extern void Hello();


    private void OnMouseDown()
    {
        string currentPos = this.transform.position.ToString();
        Debug.Log("cube clicked "+ currentPos);
        //#if UNITY_WEBGL
        Hello();
        GameObjectHasClicked(currentPos);
        //#endif
    }


}

正如您所看到的,我正在调用两个简单的方法( GameObjectHasClicked Hello )来自C#的jslib,但是

首先,每当我在编辑器模式下点击游戏对象时,它都会给我错误

EntryPointNotFoundException: Hello
SendInfoToBrowserJS.OnMouseDown () (at Assets/Scripts/SendInfoToBrowserJS.cs:29)
UnityEngine.SendMouseEvents:DoSendMouseEvents(Int32)

其次,构建是信息也是如此。实际上有三种信息:

我仔细检查了我的第一个错误

发现问题就在这里

ReferenceError: **margeInto is not defined**,,ReferenceError: margeInto is
not defined at eval (eval at load

实际上是的 mergeInto 不 margeInto ,通过替换语法错误,我能够成功构建。
