LuaRousr
Price: 9.99
Demo (lovingly provided by @net8floz)
Currently Windows Only

LuaRousr is a GMS2 Extension that enables you to run (and even reload and run again) Lua scripts with your GMS2 games. It features the ability to bind instances as Lua objects, (only instance variables are automatically bound currently) and you can bind your own functions to call from your Lua scripts as well.

This allows you to easily make moddable games but could also help larger games with iterative design. Since the scripts are 'hot reloadable' it's much easier to tweak a script and reload than having to rebuild / rerun your entire game.

Just a curiosity: Is script binding actually calling GM scripts from Lua code or just switching context between Lua and GM to issue the call back? I'm asking this in order to assess the performance penalty of binding multiple scripts

 

[babyjeans]

Internally, there's a buffer that is passed between Lua and GML. Once per step, GML ticks Lua, and then processes this buffer to make any calls that are necessary. So to oversimplify, a buffer says "call this script with these arguments" and GML does that.

EDIT: When you do a straight up call, or executeFile/String, the buffer is processed right then, and not at the 'step' part, to make the immediate execution of the script / function possible.

The 'step' part is if you're using lua coroutines.

Interesting. Might check this extension out in a few days, not personally familiar with Lua but it might be interesting nonetheless

This is one of those things that YYG should add themselves so thank you for spending the time to add this yourself.
We will definitely be using this in the future.

Keep up the great work.

Just been updated to v1.0.0!!!
Due to a bug with DLLs on Linux and OSX, those aren't published yet - but if you're interested in using them I can help get you set up. You currently are limited to using one or the other until the file naming bug for libraries is fixed (currently, they'll only work if I don't give the lib a file extension, since you can't have 2 files of the exact same name)

Dropping to $5.99 for the Holidays. You know what it goes good with? ImGuiGML! (I bet you thought I was going to say eggnog)

For the new year, we've upgraded to v1.1.1 which mainly does a bunch of cleanup and small optimizations!
