Referencing a table column by name

bjandthekatz

Hello, I am trying to call a table column based on an attribute. The attribute is the current level that the user is on and the column has multiple variations: 1type, 1x, 1y, 1w, and 1h because it holds the actors data. I was trying to use game.currentLevel.."x" and create all 5 rules to set the data, but it is showing up as 0 when called, not the correct table data. I saw somewhere that you have to use quotations when referencing a table name. How would I go about calling this data from the table? I have already tried currentLevel.."x", "currentLevel".."x" and "game.currentLevel..x"

There seems to be a problem with concatenating an integer to a text string. But if you do it the other way around it seems to work better.

Example: "x"..self.currentLevel

I don't think we can reference tables by name, at least i can't on GS Windows.
But your question is titled "referencing a table column by name" so is it column or table that you're having problems with.
So i am confused not sure i understand your question.

Wow, thank you very much! Should I submit a bug report or is it a known occurrence?

Its not exactly a bug. Its just how Lua deals with type conversion.

So you mention Lua so I looked it up and see how concatenation works.
According to this documentation, "If any of its operands is a number, Lua converts that number to a string"

I think it might be a bug in Lua then
