Step 1: Download and Install the Interpreter

First, we will need the actual Ruby interpreter, in order to execute Ruby scripts that we create. You can head over to:

http://www.ruby-lang.org/en/downloads/

There are a few ways to install Ruby, however, if you are in a Windows environment, the easiest and most painless way is to use the RubyInstaller:

http://rubyinstaller.org/downloads/

The version you get isn't overly important. RPG Maker XP/VX use (I believe) version 1.8.4

If you plan to go beyond RPG Maker scripting, I would personally choose 1.9.3 (latest version)

Once you have downloaded rubyinstaller, run the installer.

IMPORTANT:

Ensure you have "Add Ruby executables to your PATH"

In this tutorial I will be mostly working with ruby from the command prompt, and this will help that process immensely.

I would suggest associating .rb/.rbw files with this interpreter (assuming this is the only interpreter you have installed). This will allow you to run ruby scripts by double clicking on them.

tk/tcl is NOT necessary for this tutorial. tk (toolkit) is the main GUI library for ruby, and I will not be teaching that. If you wish to learn to build GUI applications with ruby, I would advise learning tk: http://www.tkdocs.co...al/onepage.html

Step 2: Confirm Installation

Simply open up a command prompt

Go to Start > Program Files > Accessories > Command Prompt

or

Go to Start > Run

Type in "cmd" (without quotes)

Click ok

Once you have a command prompt open, type:

ruby -v

The output *should* be something similar to this:

ruby 1.9.3p0 (2011-10-30) [i386-mingw32]

The exact details may vary, but if ruby -v displays a message, then everything went correctly.

If you are in a Linux based environment, you could use your package manager to get ruby.

ex. Aptitude Package Manager

sudo apt-get install ruby

You could also download the source code, and compile it yourself:

http://www.ruby-lang.org/en/downloads/

Or, what I use is, RVM - the ruby version manager

http://beginrescueend.com/rvm/basics/

This program allows you to seamlessly use and install multiple ruby interpreters side-by-side,

follow the website's directions. If you need help, I can help walk you through it in more detail.

Then to verify everthing went well:

open a terminal, type:

ruby -v

The output *should* be something similar to this:

ruby 1.9.3p0 (2011-10-30) [i386-mingw32]

Step 1: Create a new Project

Open RPG Maker (XP or VX) and create a new project.

Step 2: Setup Scripts

Open the script editor (F11 or Tools > Script Editor), and then delete EVERY SINGLE SCRIPT.

IMPORTANT: In this tutorial, when I redirect output to the console I mainly use `puts`. Unfortunately, RPG Maker does not use a console, and puts will do nothing for you. To get around this, either replace puts with `p` this will redirect the output to a Windows Message box. Or, add this script to the script editor (above any tutorial code you write)
