WebGL -- Extended Callbacks Crashing #3

Open lathertonj opened 2 years ago

lathertonj commented 2 years ago

The Extended Callback Tests scene is currently crashing on WebGL.

To reproduce:

Compile the "Chunity Extended Callback Tests" scene for WebGL
Run a simple HTTP server from the build directory, e.g. python -m SimpleHTTPServer 8080
Run the scene
You may want to comment out most of the tests to isolate one test at a time

To fix:

Fix the implementations for related functions in Chunity/Plugins/WebGL/AudioPluginChuck.jslib
For example, if FloatID is failing in ChunityTestCallbacks.cs, then the fix will lie in getChuckFloatWithID

The issue is likely with the dynamic callbacks from javascript back to C#, i.e. the dynCall. First place to look would be Emscripten documentation, as well as Unity documentation. https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html https://forum.unity.com/threads/c-jslib-2-way-communication.323629/ https://stackoverflow.com/questions/25576458/calling-a-function-pointer-with-emscripten

Not sure if this is related but when running in editor with build target being WebGL, lines containing DllImport fail due to EntryPointNotFoundException.
