That's true, I haven't released it to the public yet because there are still some minor issues, but the bulk of the work is done.

Here you can preview some of the samples running inside a web browser:

Sorry for the delay, I've been out offline on Christmas holidays.

I don't quite know emscripten to answer this question right now. The setup I have first compiles a static library libTilengine.a composed of webassembly (wasm) objects, and then builds a final wasm bundling the library, the compiled sample and packaged assets.

I know that emscripten can compile to plain asm.js instead of wasm. So in theory this intermediate library in asm.js should be usable inside a native javascript application. But as I mentioned, I don't know enough the toolchain and its possible output paths. I just learned how to build the original samples written in C. But it'ssomething that should be explored.

This documentation page talks about calling C code in a library (i.e Tilengine) from javascript code:
https://emscripten.org/docs/porting/connecting_cpp_and_javascript/Interacting-with-code.html#calling-compiled-c-functions-from-javascript-using-ccall-cwrap

1. Open a emscripted-enabled terminal by running emcmdprompt.bat batch file located inside emcscripten install directory
   
2. Navigate to Tilengine (html5 branch) root folder
   
3. Build the library by making src/Makefile_emcc:

In case you're interested, I've pushed online the html5 development branch. This is were I do all tests and changes, it's not for public release yet, but it's working. Once it's completed, my idea is to merge it into main branch and not have a separate "html5" branch anymore.

First you have to setup emscripten compiler:
https://emscripten.org/docs/getting_started/downloads.html

Following instructions are for Windows. If you're using Linux, you'll have to adapt it.

1. Open a emscripted-enabled terminal by running emcmdprompt.bat batch file located inside emcscripten install directory
   
2. Navigate to Tilengine (html5 branch) root folder
   
3. Build the library by making src/Makefile_emcc:
   

Code:

cd src
mingw32-make -f Makefile_emcc

Build the samples by executing samples/build_emcc batch file:

Code:

cd ../samples
build_emcc

Executables are located in wasm directory inside samples:

Code:

cd wasm

To run samples, execute emrun followed by the name of the sample.html.

For example to run platformer sample:

Code:

emrun platformer.html

A web browser will open with the sample running inside

Let me know if you manage to build an run without errors

Glad to know you have it working :-)

As you can see, the single main difference is that the main loop doesn't exist isnide main() function anymore, but is a delegate function set up by the new API call TLN_SetMainTask(). That's because how the browser calls javascript code. Being single-threaded, it means you can't call a function that doesn't return control to the javascript engine, a delegate callback must be used. This new mechanism is also implemented inside the Tilengine window, so the updated samples will also run when compiled to native C applications. The rest of the API is the same.
