AH, I was talking to fponticelli and he said something and it struck me what
I am doing wrong here.
This is the right c++ code :
void ncb_quickLoad(value module)
{
value o = val_field(module,val_id("NekoPtkGame"));
if( val_is_object(o))
{
value f = val_field(o,val_id("cb_quickLoad"));
if( val_is_function(f))
{
val_call0(f);
}
}
}
Now I can call functions within object that I created in neko language to
mimic what Danny said and it works.
I will go now further where I already noticed new problem, but I have to dig
deeper about it now that this works and see if I can solve it without asking
here. (When I compiled the minimal haxe file with haxe to .n my c++ app just
exits).
I already have material for 2 short tutorials until now. One is how to call
back into c++ app from embeded neko, ano another short one is this with
objects.
Best regards,
Janko
