-Algorithm for moving bad guys:
-
- * Enterprise has "force" based on condition of phaser and photon torpedoes.
- If both are operating full strength, force is 1000. If both are damaged,
- force is -1000. Having shields down subtracts an additional 1000.
-
- * Enemy has forces equal to the energy of the attacker plus
- 100*(K+R) + 500*(C+S) - 400 for novice through good levels OR
- 346*K + 400*R + 500*(C+S) - 400 for expert and emeritus.
-
- Attacker Initial energy levels (nominal):
- Klingon Romulan Commander Super-Commander
- Novice 400 700 1200
- Fair 425 750 1250
- Good 450 800 1300 1750
- Expert 475 850 1350 1875
- Emeritus 500 900 1400 2000
- VARIANCE 75 200 200 200
-
- Enemy vessels only move prior to their attack. In Novice - Good games
- only commanders move. In Expert games, all enemy vessels move if there
- is a commander present. In Emeritus games all enemy vessels move.
-
- * If Enterprise is not docked, an agressive action is taken if enemy
- forces are 1000 greater than Enterprise.
-
- Agressive action on average cuts the distance between the ship and
- the enemy to 1/4 the original.
-
- * At lower energy advantage, movement units are proportional to the
- advantage with a 650 advantage being to hold ground, 800 to move forward
- 1, 950 for two, 150 for back 4, etc. Variance of 100.
-
- If docked, is reduced by roughly 1.75*game.skill, generally forcing a
- retreat, especially at high skill levels.
-
- * Motion is limited to skill level, except for SC hi-tailing it out.
