Better control keybindings

[danielpa]

I see a lot of mods generate a list of keys when they want to add a keybinding like so:

local FIRST_NUMBER = 48
local FIRST_LETTER = 65
for i = 1, 10 do
    local ch = string.char(FIRST_NUMBER + i - 1)
    keyslist[i] = {description = ch, data = ch}
end
for i = 11, 36 do
    local ch = string.char(FIRST_LETTER + i - 11)
    keyslist[i] = {description = ch, data = ch}
end

Is there a better way to assign a keybinding for your mod?

That code generates a list of possible keys with their proper names, so people can choose which key they want from the list in the mod settings.

I mean...what is it you want to improve upon?

Like the selector don't starve provides for changing his keybindings, like attack, rotate etc...

Anyway,  here is a little improvement on the code, in case someone finds it useful

 

function generateKeys(result, from, to)
    local s = string.byte(from, 1)
    local e = string.byte(to, 1)
    do
        local i = s
        while i <= e do
            local key = string.char(i)
            result[#result + 1] = {description = key, data = key}
            i = i + 1
        end
    end
end
string = ""
local keys = {}
generateKeys(keys, "0", "9")
generateKeys(keys, "a", "z")

Yeah, I don't know if you can influence the UI like that.
