Hello, I am trying to make it so I can set a background color from a string.

Heres an example.


colortable = [colors.red,colors.blue,colors.white]

term.setBackgroundColor(colortable[1])

A post would be appricated.

Thanks,
Nolan

Just replace the [] with {} and you get a table. That sounds just like you wanted


colortable = {colors.red,colors.blue,colors.white}
term.setBackgroundColor(colortable[1])

Truth be told, the keys used to define the colours in the "colours" table are already in the form of strings.

term.setBackgroundColour(colours.red)

-- ... is the same as:

term.setBackgroundColour(colours["red"])

-- ... which is the same as:

local myCol = "red"
term.setBackgroundColour(colours[myCol])
