Eng:Encoding and Decoding Cloud Data

Encoding a cloud variable is the process where one takes a list and compiles it into a number-only format in a cloud variable. It can be used for creating large online leader-boards or even massive multiplayer online games.

Variables Needed
This tutorial will assume a few variables. These are: A single list, named users, will also be used.
 * z
 * i
 * i2
 * i3
 * data

In this example, the project will keep track of users who visit it. However, it is trivial to replace the users list with something else. Alternately, the list and repeat blocks can be removed to only encode a single variable.

Encoding
The encoding process takes each item in a list, separates them with a certain number, such as 00, and assigns each item a (preferably two-digit) number.

This project assumes that it separates them with the code. The code  is used in the following script to separate list items because no character in the variable "z" has an indexed position of 0. In simpler terms, when the cloud variable is encoded, each letter of each item of the list is added as a number. The number represents the letter in the variable "z" (which lists all characters) by which the character from the list meets its equivalent position.

For example, if the first letter of the encoding process is "b", the code representing "b" would be  because the second letter of the variable "z" is "b". The variable that contains all the letters used for parsing is named "z" because each time the variable's value is called, a shorter name takes up less processing power to report the specified character.

when gf clicked set [z v] to [0123456789abcdefghijklmnopqrstuvwxyz?] //the variable name is kept short for faster script execution

define encode set [i v] to [0] set [☁ data v] to [] repeat (length of [users v]) change [i v] by (1) set [i2 v] to [0] repeat (length of (item (i) of [users v])) change [i2 v] by (1) set [i3 v] to [0] repeat until <<(letter (i2) of (item (i) of [users v])) = (letter (i3) of (z))> or <(i3) > (length of (z))>>//if the letter is not included in the variable "z" the loop will not end, change [i3 v] by (1) end if <(i3) > (length of (z))>//so it checks if "i3" is greater than the length of "z" set [i3 v] to [37] // and replaces the letter with a "?" if that is true end if <(i3) < [10]> then //If i3 is less than 10, it needs to be ex: 03 instead of 3 set [☁ data v] to (join (☁ data) (join [0] (i3))) else set [☁ data v] to (join (☁ data) (i3)) end end set [☁ data v] to (join (☁ data) [00]) end

Decoding
Decoding takes the encoded number data and compiles a list out of it. Modifications must be made with the encoder and decoder if multiple lists need to be compiled for a project's particular purposes.

define decode set [i v] to [1] delete (all v) of [users v] add [] to [users v] repeat ((length of (☁ data)) / (2)) if <(join (letter (i) of (☁ data)) (letter ((i) + (1)) of (☁ data))) = [00]> then add [] to [users v]   else replace item (last v) of [users v] with (join (item (last v) of [users v]) (letter (join (letter (i) of (☁ data)) (letter ((i) + (1)) of (☁ data))) of (z))) end change [i v] by (2) end delete (last v) of [users v]
