Intro to Lua & C++ in Stingray

[MatthewDoyleArt]

Hi all,

A few weeks back I did a live Twitch stream that covered Lua and C++ in Stingray in considerable detail. This tutorial covers how to talk back and forth between Lua and a C++ DLL as well as Lua and Flow.

Thanks for the video Matthew!

Just wanted to point out that if you are using Visual Studio on Windows 8 or 10 you can still compile LuaJIT without the Windows 7 SDK.

Open the start menu and type:

developer command prompt

This will launch a console. You then need to set the environment to 64bit so type:

cd VC

vcvarsall.bat x64

Then you're ready to proceed with building LuaJIT 🙂

Hello Matt I was going over your Intro to Lua for Stingray and I have a question.

I have a question about this:

local level = SimpleProject.level or nil                                     
local level_name = SimpleProject.level_name or nil
local Trig_Event = stingray.Level.trigger_event                         

function Project.on_level_load_pre_flow()
     local MyObject = AbeClass()   --getting a reference to my class
    MyObject:Foo("Hello Mate")
    MyObject:Bar(3,15)                                                            
   Trig_Event(level,"explode")  

end                                                            

 In the code above level returns nil and Trig_Event works fine even though the are both declared as local when I try and get references to SimpleProject and stingray.Level.trigger_event.    The code above only works if I don't make the variable level local. Why is that?
