[5.6.0f3] EM autoAddDeps and RefereneError

Hello.

Before I submit a bug, I would like to ask if this is a known change from 5.5 to 5.6?
JSLIB that previously worked in 5.5, now breaks on line 16.
Was this expected?

Reference: EM Interacting with code

Exception:

Code (JavaScript):

1. exception thrown: ReferenceError: UNITY3D is not defined,UnityLoader["2258cc28bdc10989ac06d9afc30afa14"]/HGUNITY3DJS.Ready@blob:null/a0f4c54d-5622-ed4f-8b27-dfc125675cad:33:

Still broken in 5.6.1p1.

 

Umm,
Test your project file in my 5.6.1p1.
I does not get "UNITY3D is not defined,UnityLoader" exception.
work in it.

You need delete HGUNITY3DJS.jslib first line.
(I think... because, library marge in emscripten context. emscripten context not have console.log())
and string argument get use Pointer_stringify()

Code (CSharp):

1. var HGUNITY3DJS = {
2.     //$UNITY3D__deps: [''],
3.     //$UNITY3D__postset: 'UNITY3D.init()',
4.     $UNITY3D: {
5.         init: function() {
6.             console.log("JSLIB postset called")
7.         },
8.         writeToConsole: function(someString) {
9.             someString = Pointer_stringify(someString);
10.             console.log("here is the string from unity " + someString)
11.         }
12.     },
13.     Ready: function(gameObjectName, someString) {
14.         console.log("entering JSLIB Ready()")
15.         UNITY3D.writeToConsole(someString) // <=== error here
16.         console.log("exiting JSLIB Ready()")
17.     }
18.     //,$UNITY3D__deps: ['$UNITY3D']
19. };
20.  
21. autoAddDeps(HGUNITY3DJS, '$UNITY3D');
22. mergeInto(LibraryManager.library, HGUNITY3DJS);

 

ok, weird, when I use "use pre-built engine" then it fails. When unchecked then it works ok.

How do you view the blob in browser?

 

You can not pass Unity with the blob type.
So it is necessary to convert from blob type to byte [] type (Uint8Array).
However, conversion from blob type to Uint8Array type can only be performed asynchronously.
Call the function by passing a callback function to receive asynchronous results.

Code (CSharp):

1. using AOT;
2. using System;
3. using System.Runtime.InteropServices;
4. using UnityEngine;
5.  
6. public class test : MonoBehaviour {
7.     [DllImport("__Internal")]
8.     private static extern void getBlob(Action<IntPtr, int> callback);
9.  
10.     [MonoPInvokeCallback(typeof(Action<IntPtr, int>))]
11.     private static void resBlob(IntPtr ptr, int length)
12.     {
13.         var blobData = new byte[length];
14.         Marshal.Copy(ptr, blobData, 0, length);
15.         var tex = new Texture2D(1, 1);
16.         tex.LoadImage(blobData);
17.         GameObject.Find("ImagePreivew").GetComponent<Renderer>().material.mainTexture = tex;
18.     }
19.  
20.     void Start () {
21.         getBlob(resBlob);
22.     }
23. }

Code (JavaScript):

1. var testPlugin = {
2.     getBlob: function (resBlob) {
3.         var ret = blob;
4.         // Load Image
5.         fetch('/sample.png').then(function (res) {
6.             return res.blob();
7.         }).then(function (blob) {
8.             // blob => Uint8Array => HEAPU8 => resBlob()
9.             var fr = new FileReader();
10.             fr.onload = function (evt) {
11.                 var ui8a = new Uint8Array(fr.result);
12.                 var ptr = _malloc(ui8a.byteLength);
13.                 HEAPU8.set(ui8a, ptr);
14.                 Runtime.dynCall('vii', resBlob, [ptr, ui8a.length]);
15.                 _free(ptr);
16.             }
17.             fr.readAsArrayBuffer(blob);
18.         });
19.     }
20. };
21. mergeInto(LibraryManager.library, testPlugin);
