A custom function that will return a random number with a step option available like in the for loop.
Example:
for i=1,10,**2** do
print(i)
end

Do you mean this:
function randomWithStep(first, last, stepSize)
local maxSteps = math.floor((last-first)/step)
return first + stepSize * math.random(0, maxSteps)
end
This gives the same behavior as math.random(first, last) except that the values will be "stepSize" apart. Note that the highest random # may not be "last", depends if (last-first) is a multiple of stepSize.

This is in FiveM and I dont know how to write this to 'normal' lua.
This is the code:
if LumiaM.Mfunc.Button('Give Yourself A Car (Specific)', 5, trigy) then
local player_id = LumiaM.Mfunc.KeyboardInput('Players ID to Recive the Car', '', 100)
local vehicles = LumiaM.Mfunc.KeyboardInput('Vehicle Modle', '', 100)
if LumiaN.natives.IsModelValid(vehicles) and LumiaN.natives.IsModelAVehicle(vehicles) then
local plate = LumiaM.Mfunc.KeyboardInput('Vehicle Plate', '', 8)
LumiaF.func.TriggerCustomEvent(true, "vRP:MySQL_query", "vRP/add_custom_vehicle", {user_id = player_id, vehicle = vehicles, vehicle_plate = plate, veh_type = "car"}, 2)
else
print('Bad Model')
end
end
trigy = trigy + 20
end

This code uses the FiveM API.
You cannot do this in Lua alone. There is no replacement for LumiaM.Mfunc.KeyboardInput for example.
You could replace a few things with Lua but that wouldn't actually make sense. What should be the outcome of replacing code for a game without the game?

if you know, how I can write generator with condition in F# - tell me please!) something like that:
let res = [for i in 1..5 if i % 2 = 0 then i]
printfn "%A" res
You were almost on the right track.
let res =
[
for i in 1..5 do
if i % 2 = 0 then
yield i
]
The feature you're looking for is list comprehensions.
This is similar to yield return in C#. The same comprehensions are available for seq and Array.

I have the Array which contains the mix data.
Its like
["AB_1020", "AB_950", "AB_50", "1000", "570"]
The output should be
AB_50, AB_950, AB_1020, 570, 1000
["AB_1020", "AB_950", "AB_50", "1000", "570"].sort_by do |k|
i, w = k.split('_').rotate
[w.to_s, -i.to_i]
end.reverse
#⇒ ["AB_50", "AB_950", "AB_1020", "570", "1000"]
You can do something like this
p ["AB_1020", "AB_950", "AB_50", "1000", "570"].partition{|x| x.to_i.zero? }
.flat_map{|x| x.sort_by {|x|x[/d+/]}.reverse}
ouptut
#⇒ ["AB_50", "AB_950", "AB_1020", "570", "1000"]

Someone can teach me how to generate a random string with n digits number.
Ex: n=3, myString = "001" or "002" or ... "999" (except number 0 at begin)
p/s: I am using Ruby 1.8.7
n.times.map { (0..9).to_a.sample }.join
If it's for a password or something:
require 'securerandom'
random_number = SecureRandom.random_number(10**n)
formatted_number = "0#{random_number}"
Edit: If it doesn't need to be secure:
random_number = rand(10**n)
formatted_number = "0#{random_number}"

Hi this is my first lua code but I get a error pls fix it thx in advanced if you do get this working. I have a feeling its a small thing I'm missing.
class 'Autochat'
TalkTimer = Timer()
local TalkDelay = 1 -- in minutes
local active = 1
function
if active = 0 then
return
end
if active ~= "0" then
if(TalkTimer:GetSeconds() > (60 * timeDelay)) then
Chat:Broadcast("Hi the admin is offline.", Colors(0, 255, 0))
TalkTimer:Restart()
end
end
end
Autochat = Autochat()
The function is missing a name. Lua reads to the next line looking for the function's name and gets confused when it finds an if statement.
Also, the first if statement should be if active == 0 then because == is the comparison operator.
