I would like to propose a feature that many game developers (not only them of course) can benefit a lot when using lua embedded in a game.


Ability to define custom attributes, like in C#, for lua declarations, for functions variables and table members.

Where custom attribute is a simple string that is associated with the value, and can be access at runtime thru C interface,

They will allow defining custom handling of lua variables or functions.


As an example something like this.


Table = {

            <UIWidget=”slider” UIMin=0 UIMax=100>

            Radius = 10,



            TargetName = “MyName”,



            Color = {r=1,g=1,b=1},



            Position = {x=0,y=0,z=0},




The strings in < > brackets can be parsed by Lua and associated with the table values, and later at runtime game engine can fetch this custom attribute string, parse it

And apply special processing on the values with this attribute.


As for now I see this is one as the main lacking feature from the Lua, which is limiting its full use for game engines.

I’m quite sure it’ll be a dream feature for all game developers trying to use lua in their engines.

I would really like to hear opinions on that.
