I'm considering doing some sort of callbacks from my game to the
level script (for events). What I need is some kind of
lua_isFunctionPresent.
What I'm considering is something along the lines of:
function LoadLevel()
-- do stuff
object = LoadObject("object\fred.x","fredname")
--
end
function fredname_IsDestroyed()
-- do something
end
function fredname_IsHitByEnemy()
-- do something else
end
So when "fredname" is destroyed something like:
if( lua_isFunctionPresent("fredname_IsDestroyed")
{
lua_fn = lua_getglobal("fredname_IsDestroyed");
lua_callfunction(lua_fn);
}
gets called.
Am I barking up the wrong tree here? No doubt the lua gods will say
theres some devastatingly simple way to do it (there usually is...)
but I cannot find it.
