calling mainloop from JS never returns

[nevo natan]

I have a straight forward CPP flow as follows:

  emscripten_set_main_loop_arg(one_iter,this, 0, 1);

    while (1) {

     one_iter(this);

     SDL_Delay(time_to_next_frame());

   }

in my JS it looks like this:

function init() {

myObj = new Module.myObj();

myObj.myAction() ;

}

but myObj works great.

but the next js line never gets executed.

Any ideas how I can add myAction functionality to the mainloop?

Help much appreciated!

I don't quite understand what you want to achieve, but the emscripten_set_main_loop_arg() function will not return because its "simulate_infinite_loop" argument is true (or rather 1), this is explained here:

https://emscripten.org/docs/api_reference/emscripten.h.html#c.emscripten_set_main_loop

The infinite while-loop in the next line will block the browser-tab though and after a couple of second the browser will kill your application. The emscripten documentation has more information on that behaviour here: https://emscripten.org/docs/porting/emscripten-runtime-environment.html#emscripten-runtime-environment

I don't understand how the JS snippet is related to this though, too little information :)
