** CAUSE SUPERNOVA TO OCCUR
|
||
**
|
||
** A supernova occurs. If 'ix' < 0, a random quadrant is chosen;
|
||
** otherwise, the current quadrant is taken, and (ix, iy) give
|
||
** the sector quadrants of the star which is blowing up.
|
||
**
|
||
** If the supernova turns out to be in the quadrant you are in,
|
||
** you go into "emergency override mode", which tries to get you
|
||
** out of the quadrant as fast as possible. However, if you
|
||
** don't have enough fuel, or if you by chance run into something,
|
||
** or some such thing, you blow up anyway. Oh yeh, if you are
|
||
** within two sectors of the star, there is nothing that can
|
||
** be done for you.
|
||
**
|
||
** When a star has gone supernova, the quadrant becomes uninhab-
|
||
** itable for the rest of eternity, i.e., the game. If you ever
|
||
** try stopping in such a quadrant, you will go into emergency
|
||
** override mode.
