Hello! I need to somehow get data from a hardware serial port (win32) to somewhere I can access it with serverside LUA in a timely manner. (yaw/pitch/roll values for a player.SetEyeAngles type thing.)
I haven’t done much LUA but I’m decent with C++. So far I figure my options are:
Write data to a text file then read it from LUA. I can see this being slow and buggy.
Run an external application and try to do this through sockets, adding more lag and drag on the system.
Ideally, make or steal a binary module in C++ that reads the serial port and returns an Angle.
I’ve read through http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexbfe8.html
and gotten the example from http://wiki.garrysmod.com/page/Creating_Binary_Modules
to compile and run, but I haven’t been able to find anything approaching a reference for doing this stuff. Can I just stick raw C++ serial object code into the module? How do I pass data of type Angle back to LUA? Has anyone tried this or similar before?
Any information, help, or links would be greatly appreciated!
