Really stumped on "GameCore::createGame();"
by Vince Gee · in Torque 3D Professional · 05/16/2012 (8:57 am) · 3 replies
The syntax GameCore::CreateGame as far as I understood meant to lookup the GameCore Package, and execute the function named CreateGame.
The code below finds the namespace, but the namespace doesn't have any functions in it's mEntryList, so it can't find the function.
I am really at a loss, I have a work around, but does anyone have a clue what I'm missing?

- When is this function running? Has the function been created yet?
- isFunction is a global lookup.
- Go into c_scripting.cpp and look at this function: "script_get_namespace_entry" It should help give you some ideas.
Here is the code for isFunction, it does not search against the namespace:bool isFunction(const char *fn) { const char *string = StringTable->lookup(fn); if(!string) return false; else return Namespace::global()->lookup(string) != NULL; }
