Some function calls fail on Uncaught RuntimeError

[stanoddly]

I found that plenty of function call fails on Uncaught RuntimeError: null function or function signature mismatch. The most absurd occasion I found is a call to Raylib.ColorAlpha, which is a very simple function accepting Color and float. It's from this example:
https://disketteman.github.io/DotnetRaylibWasm/raylib.html?arg=Camera3dFree

My wild guess is that it got trimmed for whatever reason during a build, but more investigation is needed. It's possible to find what specifically failed using this approach:
emscripten-core/emscripten#16305 (comment)

No need for EM_ASM({ Module.wasmTable = wasmTable; });, the table is already generated by --emit-symbol-map.

When running on debug without -O2:

3875 translates into call to ICU:

3875:icu::Hashtable::nextElement\28int&\29\20const

I checked few other examples and it was about ICU calls too. I'm not sure how ICU fits into this since the call doesn't use any string whatsoever.

This is really bizarre, looks like ColorAlpha is failing indeed.

I tweaked this line:
https://github.com/disketteman/DotnetRaylibWasm/blob/6ccfd24ce7cec603cbb69c8c6b84026724f0af28/Examples/Core/Camera3dFree.cs#L73

Into this:

                Console.WriteLine("Before ColorAlpha");
                Color color = ColorAlpha(SKYBLUE, 0.5f);
                Console.WriteLine("After ColorAlpha");

And it fails indeed:

So for some really odd reason replacing a call to Raylib.ColorAlpha with this snippet:

                Color color = SKYBLUE;
                color.a = (byte)(color.a * 0.5f);

here:
https://github.com/disketteman/DotnetRaylibWasm/blob/6ccfd24ce7cec603cbb69c8c6b84026724f0af28/Examples/Core/Camera3dFree.cs#L73

Makes this example work. Puzzling.

So it turned out that the result of:

dotnet build

is actually buggy (❓ ).

To create something which REALLY works publish needs to be used.

dotnet publish
