Set Global Lua Variable in Leadwerks 3

[SpiderPig]

In LE2 the following code worked for setting a global variable in lua,

 

BP L=GetLuaState();
lua_pushobject(L,camera);
lua_setglobal(L,"camera");
lua_pop(L,1);

 

but in LE3 GetLuaState() and lua_pushobject() doesn't seem to exist...

Are there other ways to set global variables from c++ now? A command like GetCurrentCamera() would be useful...

I think if you make a new Lua project, then open up the VS solution and look at the code in there you can find a way to do this as.

lua_pushobject(Interpreter::L,camera);
lua_setglobal(Interpreter::L,"camera");
lua_pop(Interpreter::L,1);

Thanks for the info guys, but lua_pushobject is not defined? I've updated my project just to be sure, but still it's not there

Interpreter::PushObject(Object* o)

 

Almost every Lua function has an analog in the Interpreter class.

It compiles now, but I get an unhandled exception at PushObject. ...I created this project in the editor as a C++ project by the way - does it need to be set-up as a Lua project in order to work?

Try this initialization code first:

if (Interpreter::L==NULL) Interpreter::Reset();

That fixed it. Thanks!
