My goal is to make a csv file reader for some pictures that lead to other pictures, something like a gps, but I get this notification:

Error
Pictures.lua:38: table index is nil
Traceback

Pictures.lua:38: in function 'init'
class.lua:79: in function 'Pictures'
main.lua:30: in function 'load'

My code is this:

Code: Select all

local csvFile = love.filesystem.read('myCsv.csv')

    local values = {}
    local firstLine = true

    while string.len(csvFile) > 0 do
        local index = string.find(csvFile, "\n") or string.len(csvFile)
        local line = string.sub(csvFile, 1, index - 1)
        local lineValues = {}

        for value in string.gmatch(line, "%w+") do
            if firstLine then
                table.insert(values, value)
            else
                table.insert(lineValues, value)
            end
        end
         
        if not firstLine then
            paths[lineValues[1] .. '.jpeg'] = {}

            local size = #lineValues
            for i = 2, size do
                paths[lineValues[1] .. '.jpeg'][values[i]] = lineValues[2] .. '.jpeg' (error line)
            end
        end

        firstLine = false
        csvFile = string.sub(csvFile, index + 1)
    end

Can anybody help?

t = {} ; t[nil] = 1
