我正在尝试WebGL的示例代码，但问题是我的构建失败了。这是我的密码。
jslib
margeInto(LibraryManager.library,{
GameObjectHasClicked : function (str){
window.alert(Pointer_stringify(str));
},
Hello: function (){
window.alert(Pointer_stringify(str));
},
});
和UnityC#脚本
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，我正在从C#调用jslib的两个简单方法(GameObjectHasClicked，Hello)，但是
首先，每当我在编辑器模式中点击游戏对象时，它都会给我错误
EntryPointNotFoundException: Hello
SendInfoToBrowserJS.OnMouseDown () (at Assets/Scripts/SendInfoToBrowserJS.cs:29)
UnityEngine.SendMouseEvents:DoSendMouseEvents(Int32)
其次，构建是失败并成功(但没有构建)消息。实际上有三个消息：
第一条错误消息：

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