41 | ** Automatic Override | |
42 | ** | |
43 | ** If we should be so unlucky as to be caught in a quadrant | |
44 | ** with a supernova in it, this routine is called. It is | |
45 | ** called from checkcond(). | |
46 | ** | |
47 | ** It sets you to a random warp (guaranteed to be over 6.0) | |
48 | ** and starts sending you off "somewhere" (whereever that is). | |
49 | ** | |
50 | ** Please note that it is VERY important that you reset your | |
51 | ** warp speed after the automatic override is called. The new | |
52 | ** warp factor does not stay in effect for just this routine. | |
53 | ** | |
54 | ** This routine will never try to send you more than sqrt(2) | |
55 | ** quadrants, since that is all that is needed. | |
