Robots Manual
Robots is a graphical version of the original text-based robots game, which can be found on a number of UNIX systems. The player must outwit the robots chasing him/her by getting them to run into each other.

Introduction
GNOME Robots is a game where you try and avoid a band of marauding robots which are, for no adequately explained reason, trying to kill you. It is based on the text-based robots game which can be found on a number of UNIX systems.
This new version includes two types of robots, movable junkheaps, multiple game configurations, user definable keyboard layouts, and sound, as well as all of the features which were present in the original GNOME Robots game.
To run GNOME Robots, select Games Robots from the Main Menu, or type gnobots2 on the command line.
GNOME Robots is included in the gnome-games package, which is part of the GNOME desktop environment. This document describes version 2.18 of GNOME Robots.

GNOME Robots Objective
The objective of GNOME Robots is quite simple. You are surrounded by a number of robots or other hostile adversaries. As you move about they will move directly towards you for every move that you make. Their goal is to kill you. Your goal is to kill all the robots on the board by taking advantage of their vulnerabilities.
Robots are destroyed when they collide with each other, or when they collide with the debris of some previous collision. You die if a robot ends up right next to you.
In some of the game configurations (you can choose from five different sets of rules), you can push the junkheaps around to form barricades to protect you. Also, if you are daring enough, you can Splat! the robots by pushing junkheaps on top of them for an additional bonus.
You can also save yourself by teleporting yourself to a random location. Unfortunately, randomly teleporting means that you might end up being right next to a robot, so they can kill you when they make their move. Luckily, there are also safe teleports which will place you out of immediate danger, but there are only a limited supply of them. You can earn more free teleports as you go along (how you gain them depends on the chosen game), but typically you get one for each robot that is destroyed while you are 'waiting', up to a maximum of 10. If you don't want to waste your saved-up safe teleports, you can choose to teleport randomly if you think it's safe enough.
If you press the Wait button (see below) you will no longer be able to move until either all of the robots (which still move towards you) are gone, or you are killed. Doing this is risky, but may earn you extra safe teleports.
If you manage to reach the point where more than half of the screen is occupied by robots, the number of robots will be reset to the starting amount, allowing you to continue.

Using GNOME Robots
GNOME Robots is extremely simple to play. You can use either the mouse or the keyboard. This section describes basic usage of GNOME Robots.

Basic usage
Starting GNOME Robots opens the Main window, shown in GNOME Robots Main Window.

To start a new game, choose New in the Game menu or click on the New button on the toolbar.
To move, either click in the direction you want to move (the cursor will show you which way you will go) or press the appropriate key on the keyboard (keypad by default). Clicking on the little man will keep you still. To teleport (safely or unsafely), and to wait, use the buttons on the toolbar or use the items in the Move menu.

Menus
The menu bar, located at the top of the game board, contains the following menus:
Game 	 This menu contains three items:
Ctrl-N New — starts a new game of GNOME Robots.
Scores — shows the higher scores.
Ctrl-Q Quit
Move 	 This menu contains:
Teleport— teleports you in a safe location.
Random— teleports you in a random location.
Wait— places you in wait mode.
Settings 	 The Settings menu contains only one item:
Preferences which brings up the preferences dialog box.
Help 	 This menu contains:
Contents— shows this manual.
About— shows basic information about GNOME Robots, such as the author's name and the application version number.

Using the keyboard
You can use the keyboard to control the little man. By default, the keys from the keypad are configured for the game. However you can customise the key mappings in the Keyboard tab in the Preferences dialogue. To select a different key for a command, double-click on the line for that command and then press the key you want to use.

Default Key Mappings
By default, you use the numeric keypad on the right-hand side of the keyboard (not the separate arrow keys).

Switch off the NumLock Key
You may need to switch off the NumLock to make these work.

Customising GNOME Robots
You can modify the behaviour and appearance of the game by selecting Preferences under the Settings menu. This brings up a dialog with three tabs:
Game — This page allows you to choose the type of game you want to play. The drop-down box at the top of the page allows you to choose from a number of predefined games. You can't change these options in the middle of a game, so they will be disabled then. There are also several options at the bottom of the dialog:
The safe moves option will help you to avoid being killed due to a mistake. If you try to make a move that would lead to your death when there is a safe move available, you will not be allowed to proceed. But be warned: if there was no safe move available, other than teleporting, the move will be allowed to proceed.
There is also a super safe mode. If you select this, you get beeped when there is no safe move and your only option is to teleport out.
If you select the sound checkbox the game will play sounds for various events throughout the game.
The Splats checkbox selects whether you want the sound played and a small Splat! to appear on the screen.
Appearance — This page allows you to select the graphics used throughout the game from the list in the dropdown-box. You can also select the background colour from this tab.
Keyboard — This screen allows you to define your own keyboard controls. To select a different key for a command, double-click on the button for that command and then press the key you want to use.
Any changes you make take effect immediately and are automatically saved.
You can design your own graphics for the game if you want. The graphics files are found in $PREFIX/share/gnome-games/gnobots2/pixmaps, where $PREFIX is the prefix into which GNOME was installed. This is usually either /usr or /usr/local.
Each character is 16×16 pixels and there are 14 of them arranged in a PNG file which is 224×16 pixels in size. You can look at the existing files to see the order in which they must be arranged to produce the correct animated sequences.
Any graphics files which are placed in the directory are auto-detected, so you don't need to alter any configuration files. You can also define your own game configurations by creating extra .cfg files which are stored in the $PREFIX/share/gnome-games/gnobots2/games directory.
