I'd like to know how to get input from the user (a number) and then looping the number the user entered.

So it'd work like this

Number: 2
Running through loop : 0
Running through loop : 1

Now, i can print and read from user:

print ("Enter number: ")
max_value = io.read()

My problem is looping max_value number of times, thanks.

That code gave this to me:

lua: helloworld.lua:1: unexpected symbol near ';'

That code gave:

lua: helloworld.lua:6: 'then' expected near 'for'
I'm getting a bit pissed at Lua, the syntax is confusing.

get_num = function()
  print("Enter number: ")
  max_value = io.read("*number")
end
if type(max_value) == number then
  for i=1,max_value,1 do print(i) end
else
  print("Not a Number!")
endThis returns "Not a Number!".

get_num = function()
  print("Enter number: ")
  max_value = io.read("*number")
end
if type(max_value) == number then
  for i=1,max_value,1 do print(i) end
else
  print("Not a Number!")
  break
end
This returns "lua: helloworld.lua:10: no loop to break near 'end'."

I'm more fluent in Lua syntax than most other languages, it's easy when you memorize it.

Then perhaps you can help me please?

The problem I have is the nSpire platform, I can't even make a loop to draw a screen.

Perhaps I should link you to the forum where this topic is.

Right here.

Code: [Select]

  print("Enter number: ")
  max_value = io.read("*number")
  if type(max_value) == "number" then
  for i=1,max_value,1 do print(i) end
  else
  print("Not a Number!")
  end
This seems to work.

Indeed it works, thanks a lot

Phew, after a while, I managed to make my first program

print("Enter number: ")
max_value = io.read("*number")           --Get maximum random number
if type(max_value) == "number" then      --If the user enters a number

  math.randomseed( os.time() )
  random_number = math.random(max_value) --Define a number
 
  while true do
    print ("Guess a number: ")
    tried_number = io.read("*number")
    if type(tried_number) == "number" then
      if tried_number == random_number then
        print ("You Won")
        break
      end
    end
  end

else
  print("Not a Number!")
  end
I will still add a few checks and other stuff, but this language is not really for me.

EDIT:

Yay, added a few cool stuff:

print("Enter number: ")
max_value = io.read("*number")           --Get maximum random number
if type(max_value) == "number" then      --If the user enters a number

  math.randomseed( os.time() )
  random_number = math.random(max_value) --Define a number
 
  while true do
    print ("Guess a number: ")
    tried_number = io.read("*number")
    if type(tried_number) == "number" then
      if tried_number == random_number then
        print ("You Won")
        break
      elseif tried_number > random_number then
        print ("Try a lower number")
      else
        print ("Try a higher number")
      end
    else
      print ("Not a number!")
    end
  end

else
  print("Not a number!")
  end
