NAME

       Thrust - a port of the C64 classic

SYNOPSIS

       thrust [--help] [--version] [--nodemo] [--nosoundeffects] [--gamma=Value] [--step] [--svgamode=MODE]

       xthrust [--help] [--version] [--nodemo] [--nosoundeffects] [--gamma=Value] [--step] [--noshm] [--double] [-display display-name]
       [-geometry=geometry-spec]

DESCRIPTION

       This is a port of Thrust, the classic Commodore 64 game, to un*x and MSDOG.

       The object of the game is to lift the Klystron Pod from the bottom of a cave and return it safely to space. The Pod is very heavy (compared
       to the ship) and this makes it tougher than it may seem.

       You must be careful not to run out of fuel, crash into the cave walls, or let the enemy artillary outposts shoot you down.

BACKGOUND STORY

       The resistance is about to launch a major offensive against the Intergalactic Empire. In preparation for this, they have captured several
       battle-grade starships, but they lack the essential power sources for these formidable craft; Klystron Pods.

       You have been commissioned by resistance to steal these pods from the Empire's storage planets. Each planet is defended by a battery of
       Limpet Guns, powered by a Nuclear Power Plant. By firing shots at the power plant, the guns can be temporarily disabled; the more shots
       fired at the nuclear reactor, the longer the guns will take to recharge.

       BUT BEWARE!! If you fire too many shots at the reactor, it will become critical, giving you just ten seconds to clear the plantet before it
       is destroyed. If you have not already retrieved the pod stored at the planet, then you will have failed the mission. If you have retrieved
       the pod, and you manage to send the reactor into its critical phase, and leave the planet safely, you will receive a hefty bonus.

OPTIONS

       -h, --help
	    Print a usage message and exit with a non-zero status.

       -v, --version
	    Print version information on standard output, then exit.

       -d, --nodemo
	    Do not run the demo which is otherwise displayed if the game is left untouched.

       -e, --nosoundeffects
	    If sound is compiled in, be silent anyway.

       -c, --gamma=Value
	    Change the brightness of the colors. 1.0 is the default. Higher values give brighter colors. The value must be positive.

       -j, --jump
	    Only draw every third frame. This makes the game a lot faster.

       -s, --svgamode=MODE
	    This option is only applicable to the SVGAlib version of Thrust.

	    The format of svgamode is G<width>x<height>x<colors> where <width>x<height> is at least 320x200 and <colors> has to be 256. Also, the
	    mode cannot be planar. See the SVGAlib documentation for details on this. The default is G320x200x256. There has been success with
	    modes G320x200x256, G640x480x256, G800x600x256 and G1024x768x256.

       -display display-name
       -geometry geometry-spec
	    These options (-display and -geometry) are only applicable to the X version of Thrust. Se the man page of X for details.

       -m, --noshm
	    This option is only applicable to the X version of Thrust.

	    Do not try to share memory between Thrust and the X server.

       -2, --double
	    This option is only applicable to the X version of Thrust.

	    Double the size of the window. This makes the game slow.

CONTROLS

       Note that the following keys are the default configuration. This can be changed by the user by creating a file named .thrustrc in the users
       home directory.

       A    Turn counterclockwise

       S    Turn clockwise

       Enter
	    Fire

	    Shoots a bullet. Different targets have different effect:

	    The Fuel Tank explodes for 150 points.

	    The Limpet guns expolde for 750 points.

	    The Nuclear Power Plant can take a number of hits. When they are destroyed you are given a short period of time to clear out before
	    the whole neighbourhood is nuked. If a Power Plant is hit - but not destoyed - it will recover after a period of time. During this
	    recovery period, the Limpet guns are not able to fire. 2000 extra points are scored if the Power Plant is destroyed when the level is
	    finished. There is exactly one Power Plant in every level.

	    In the more advanced levels you will find other things to shoot at.

       Right-Ctrl (Right-Shift on MSDOG)
	    Thrust

	    Gives the ship a forward push at the cost of some fuel.

       Spacebar
	    Pick up and shield.

	    If the ship is above a Fuel Tank the ship is refueled, i.e the fuel is picked up. Two vertical bars are drawn to indicate that fuel is
	    picked up. When there is no more fuel left in the tank, it disappears and 300 points are scored.

	    If the ship is close to the Klystron Pod a connecting wire is drawn. The Pod is picked up when the connecting wire is of the right
	    length. If spacebar is released before the correct distance is reached the Pod is not picked up.

	    When the shield is activated, a circle is drawn around the ship. If the ship is carrying the Pod, the Pod and the wire are also
	    protected by the shield. The shield costs fuel to power.

       ESC/Q
	    Quit the game

       P    Pause

       C    Continue a paused game

CONFIGURATION

       The .thrustrc file

       Each command can be customized for either X11 or the SVGAlib (console) versions by specifying the appropriate prefix, X11- or SVGA-,
       followed by the command, and the key to be assigned. Numpad keys can be assigned using KP_[number], and control, shift and alt keys can be
       assigned using [key]_[direction].

       Valid commands:

       counterclockwise
       clockwise
       thrust
       fire
       pickup

       Examples:

       X11-counterclockwise    a
       X11-clockwise	       KP_6
       SVGA-thrust	       Shift_L
       SVGA-fire	       space
       SVGA-pickup	       KP_0
