why lua version schedule update pass string as parameter to the callback

cocos2d-x Lua
1

I’m studying the lua example and mod something for fun. The lua example’s tick function doesn’t contain the parameter so I add it like this.
function tick(dt)
xxxx
end

And then I try echo dt find that is a string type.

bool CCLuaScriptModule::executeSchedule(const std::string& handler_name, ccTime cc){
//blah blah blah
lua_pushfstring(d_state, “%f”, cc);
…
}

If my func depends on it. The ccTime must be convert to number type again.
So I just mod this to, everything works fine
lua_pushnumber(d_state, cc);

I don’t know why?

Anther I wanna know does the lua version have memory leak? I really want to write my commerial game in lua.

Yes, we have found memory leak. But I don’t know if it is a bug of lua. You can use other version to make sure, and le me know.
Because I am busy these days, and have no time to do it.

Thank you.
