41 | ** Check for Condition After a Move | |
42 | ** | |
43 | ** Various ship conditions are checked. First we check | |
44 | ** to see if we have already lost the game, due to running | |
45 | ** out of life support reserves, running out of energy, | |
46 | ** or running out of crew members. The check for running | |
47 | ** out of time is in events(). | |
48 | ** | |
49 | ** If we are in automatic override mode (Etc.nkling < 0), we | |
50 | ** don't want to do anything else, lest we call autover | |
51 | ** recursively. | |
52 | ** | |
53 | ** In the normal case, if there is a supernova, we call | |
54 | ** autover() to help us escape. If after calling autover() | |
55 | ** we are still in the grips of a supernova, we get burnt | |
56 | ** up. | |
57 | ** | |
58 | ** If there are no Klingons in this quadrant, we nullify any | |
59 | ** distress calls which might exist. | |
60 | ** | |
61 | ** We then set the condition code, based on the energy level | |
62 | ** and battle conditions. | |
