| 20 | ** Check for Condition After a Move | |
| 21 | ** | |
| 22 | ** Various ship conditions are checked. First we check | |
| 23 | ** to see if we have already lost the game, due to running | |
| 24 | ** out of life support reserves, running out of energy, | |
| 25 | ** or running out of crew members. The check for running | |
| 26 | ** out of time is in events(). | |
| 27 | ** | |
| 28 | ** If we are in automatic override mode (Etc.nkling < 0), we | |
| 29 | ** don't want to do anything else, lest we call autover | |
| 30 | ** recursively. | |
| 31 | ** | |
| 32 | ** In the normal case, if there is a supernova, we call | |
| 33 | ** autover() to help us escape. If after calling autover() | |
| 34 | ** we are still in the grips of a supernova, we get burnt | |
| 35 | ** up. | |
| 36 | ** | |
| 37 | ** If there are no Klingons in this quadrant, we nullify any | |
| 38 | ** distress calls which might exist. | |
| 39 | ** | |
| 40 | ** We then set the condition code, based on the energy level | |
| 41 | ** and battle conditions. | |
