| 25 | ** Automatic Override |
| 26 | ** |
| 27 | ** If we should be so unlucky as to be caught in a quadrant |
| 28 | ** with a supernova in it, this routine is called. It is |
| 29 | ** called from checkcond(). |
| 30 | ** |
| 31 | ** It sets you to a random warp (guaranteed to be over 6.0) |
| 32 | ** and starts sending you off "somewhere" (whereever that is). |
| 33 | ** |
| 34 | ** Please note that it is VERY important that you reset your |
| 35 | ** warp speed after the automatic override is called. The new |
| 36 | ** warp factor does not stay in effect for just this routine. |
| 37 | ** |
| 38 | ** This routine will never try to send you more than sqrt(2) |
| 39 | ** quadrants, since that is all that is needed. |
