Lesson 2: Familiarizing Yourself with the Workspace
The purple lines that you see in three of the views is actually a cube and the lines represent the walls of this cube. Each wall is a double line so you can see the inside wall and the outside wall. Much like any kind of container there is an inside and an outside.
Without doing anything else now hit the enter button. The default pattern is applied to your purple cube. You can see this default pattern in the window on the upper left. It is yellow with a bunch of round faces.

What you have done here when you hit the enter button is accepted the purple cube as a hollow object. In effect you have created your first room!
Want to take a look around inside this new room?
Left click on the textured window (smiley faces) hold and drag it around and your view changes. Drag down and you pull away. Voila the room takes shape. You can see where the walls, floor and ceiling meet.

You can even pull completely out of the room by bringing your mouse down. Now you can look at the outside of it.

Not too hard now was it? Note that if you don't see the green lines in your 3d view simply click inside this view and they will appear.
Now let's change this texture because it has definitely got to go! It can make you sea sick.
Click on the textures tab. This is where a whole variety of textures is stored.
Directly underneath this tab you will now see a variety of textures to choose from. The smiley head is also included in this list. Double click on a new texture -something a little more game like and it will be applied to your room. If it isn't applied to your room simply click on the room in the 3d view.
Here is what the room looks like with a new texture applied:

Now isn't that much better? This isn't too hard is it? You are going to get real good at this. And applying textures is very important. It gives your world the look and feel you are trying to achieve.
You have actually started making a video game.

Lesson 3: Now let's add a character and actually walk around inside this room. This is where it starts to get fun! You can have something up and running in just a matter of minutes.
Hit the tab called templates.
Directly underneath this tab, and a little way down the page is a drop down box called "Entities"
Pull down this menu and select Player setup then hit enter on your keyboard.
This causes a small icon to appear in your room. This (Player setup) gives your player all of its characteristics.
Now let's place a player in the game. Reality factory already has pre-made players for you so all you have to do is place it in the game.
Pull down the Entities menu again and select Player start.
Now click on your 3d view and look around. Near the floor a light bulb has been placed in the room. This is the player start. Hit Enter again and the light bulb will change to a little red box that says player start.
This is your player!
Now lets run this and take a walk around inside.
Click the Build button. This takes the world you built and compiles it into an actual game world.
Now a menu appears. Check the box called Preview in Reality Factory. and then hit OK.

The world is built and you now can take a walk around your new room! That didn't take long did it. Reality Factory is an amazing tool that does all of the programming work for you. You can focus on the creativity of building a game.
Lesson 4: Now You actually have your very first game and most of the hard work was actually already done for you. This Reality Factory software is designed to do exactly that. It will do most of the hard work and leave the creativity to you. You will be free to design games and worlds. Let's look at a screen shot of the one room game you built. This is the modern world of game design. All the hard work is done for you and you are left to do the creating! But as you get better you will be delving deeper into the game and you will be creating your own character, guns, weapons, and whatever else you can think of. But for now this is just a good start in your video game making.
Looks pretty good doesn't it! You saw that you started the game up and had to choose a character and a name. Then you were popped right into the room you made. Right now you can see the shotgun I am holding and in the upper left you can see my health bar and in the upper right is my radar screen where I can see enemies.
To play you would use the left mouse to fire the shotgun and the W-A-S-D keys are for motion and the space bar is for jumping.
The player start and player setup entities you dropped into the room were prefabrications and for now this is great because you can focus on designing games and levels. But of course this is just what came with the software and you can design your own characters and players with their own unique weapons and characteristics and put them in the game. But that will come with time and practice. For now this tutorial will focus on understanding how to use the desktop to design some nice looking game levels. .
Now I recommend you review these lessons; start from the beginning and make another room. This is important because you need to do this without thinking about it. Build one or two more rooms and then run them. Try using different textures and see how it looks.
Once you have built another room or two then you can continue on with the lessons.
