NAME    [Toc]    [Back]

     blast - 3D	space war game

SYNOPSIS    [Toc]    [Back]

     blast [-T]	[-t time] [-a]

DESCRIPTION    [Toc]    [Back]

     blast is an interactive 3D	game where the user destroys asteroids to gain
     points. There are several large asteroids in orbit	around a small protoplanet.
  From your	space station base, you	must venture out and shoot
     these asteroids to	break them into	smaller	pieces without colliding into
     either the	asteroids or the proto-planet.	Watch out for the alien	ship
     that fires	back at	you!  Destroy this ship	before it destroys you.	(All
     divestments, embargoes, blockades,	economic sanctions, and	other political
 actions have failed with the 'aliens')

OPTIONS    [Toc]    [Back]

     -T	is for no texture mapping

     -t	<time>	is for duration	of play.  <time> is in integer units of	view
     updates.  2000 is about a minute depending	on frame rates.

     -a	is for audio (currently	only for vigra board)

CONTROLS    [Toc]    [Back]

	  The leftmouse	button fires your rockets to move forward.

	  On a PI or INDIGO: The middlemouse button enables the	rocket to move
     in	a roll/pitch motion instead of the default yaw/pitch.

	  On a PowerVision or RealityEngine: the middlemouse button fires an
     asteroid seeking missile

	  The rightmouse button	fires normal missiles


	  The X	position of the	mouse controls your yaw

	  The Y	position of the	mouse controls your pitch

	  The space bar	will show a set	of 3D lines that point toward asteroids.
  Green lines point to asteroids in front of you, blue lines
     point behind.


	  There	are inertial dampeners that will eventually slow you down if
     you do not	fire your rocket thrusters.

SCORE    [Toc]    [Back]

	  BIG asteroids:	 20 pts
	  MEDIUM asteroids:	 50 pts
	  SMALL	asteroids:	100 pts
	  alien	ship:	       200 pts

	  The score is shown as	a large	red LED	display
	  your speed is	shown as a small yellow	LED display
	  time left is shown as	a small	green LED display

NOTES    [Toc]    [Back]

	     It	takes a	lot of practice	to be able to judge the	proper amount
     to	lead an	object when firing at it.  This	makes hitting an asteroid
     rather tricky for the novice.  Note that asteroid size, speed, direction
     of	travel,	and distance all have to be taken into account.	  The easiest
     way for a beginner	to actually hit	an asteroid is to fly up close to it.

	     The yaw and pitch controls	are a little bit like those in an airplane.
  pulling the mouse towards you makes you pitch up, just as pulling
     an	airplane stick towards you makes the plane pitch up

	     asteroids that fall onto the proto-plane self destruct on impact

	     After the number of remaining asteroids is	diminished, a new set
	     of	asteroids appear.

	     After 3 lives are used up,	game prompts user for a	reset
