Help with using coroutines

[Nino Jagar <njagar@...>]

Hello,

I have two lua scripts which represents levels.

Each time a level is loaded it's respective StartLevel script is called in another thread like this:

lua_State *thr = lua_newthread(LuaMain);

lua_getglobal(thr, "StartLevel"); 

lua_pcall(thr, 0, 0, 0);

In first script I'm trying to call C function (StartExplosion) and then I want to wait until it's over.

After that I'm trying to start that coroutine again to load another level (LoadLevel) function.

I've tried returning lua_yield() from StartExplosion function and then calling lua_resume from main game loop after 10s have elapsed, but it doesn't work at all.

It seems that I need to use lua_pcallk but there is no example how to use it, can you please help me by writing a small example?

Or is it done in a completely different way?

my lua function looks like this:

**level1.lua**

function StartLevel

  StartExplosion();

  LoadLevel("level2.lua");

end

**level2.lua**

function StartLevel

  print("hello");

end

Thanks!
