EntryPointNotFoundException外部JS库错误

Question

Trying to implement JS library with my C# code. Is very simple but I am getting this error:

EntryPointNotFoundException: Test TalkDB.Start () (at Assets/Scripts/TalkDB.cs:30)

C# code is in scripts folder and JS library at plugins/webgl with .jslib extension. Also read this article, but no idea what I am missing: https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html?_ga=1.27144893.1658401563.1487328483

C# Code:

public class TalkDB : MonoBehaviour
{
    [DllImport("__Internal")]
    private static extern void Test();

    void Start()
    {

        Test();

    }
}

JS Library:

var HighscorePlugin = {
    Test: function()
    {
        window.alert("Testing 1, 2, 3,...");
    }
};

mergeInto(LibraryManager.library, HighscorePlugin);

Answer 1

Found the answer, is quite simple in fact. I does not work when running locally, just when running from a server. To prevent this error this should be done:

#if UNITY_WEBGL && !UNITY_EDITOR

[DllImport("__Internal")] private static extern void Test(); #else

// something else to emulate what you want to do

#endif

And do this also when calling the function. Happy programming :)

Answer 2

EntryPointNotFoundExceptionmeans means that the function "Test" is either (A) not marked as exportable (not visible) or (B) signature does not match C# definition.

Most likely your issue is the former (A).

I would recommend running DUMPBIN.EXE against your library to verify your "test" function is getting exported and that the its respective signature matches your C# definition. Could be some code-injection on JS-side.
