My background prior to about 6 weeks ago was Adobe Flash back to the Flash 3 and the Macromedia days. It was very common for some of the swf apps I wrote to use dynamic variables for repetative tasks. In ActionScript it would be something like this:
1 2 | num = 1; eval("box" + num) == 10 |
One possible problem is you declared your swapAbilities function as local. The function won't be defined in other modules if you do that.
Also FYI, there is a built in Lua-ism for swapping. In Lua, you can do:
a=1
b=2
a,b = b,a
-- a is now 2, b is now 1
You don't need a temporary variable.
Brilliant!! I will incorporate this into the function. I will test your local theory on the function as well. There are probably much better ways to do this but I think I will stumble on and try to work it through. If anything it might teach me a few things. ;)
Thanks for taking the time to help!

Does removing the word "Local" make the function Global? If so, it didn't work. It's almost like the "_G" is for some reason not available to the external module. Is that possible?
1 2 3 4 | _G[swapValue1],_G[stat] = _G[stat],_G[swapValue1] -- Where swapValue1 = "dex" and stat = "str", this FAILS str,dex = dex,str -- These are global variables, work fine. |
If you are using the Lua module system, I think there are visibility things that change the environment to insulate changes to _G to not contaminate your main program.
module(..., package.seeall) has something to do with this.
Well, I am using:
1 | module(..., package.seeall) |
