Damage_taken =
   Trunc(100 * MineHitDamageFor100KT / Hull_mass)
                     ...for normal mines
   Trunc(100 * WebHitDamageFor100KT / Hull_mass)
                     ...for web mines

Other effects of a mine hit (all of them are checked, in this order):

• if the ship hit a web mine, it burns Max(WebHitFuelLoss, Fuel/6) fuel, and stops (warp 0).
• if the ship is Lizard and has 150% damage or more, it explodes.
• if the ship is not Lizard and has 100% damage or more, it explodes.
• if the ship exceeds the DamageLevelForCloakFail, it de-cloaks (this affects its mine hit odds for further movement, if any).
• if the ship has hardened engines, it continues movement normally (unless it hit a web mine, in which case its speed is now 0).
• otherwise,
  • if HullTechNotSlowedByMines = 0, its speed is recomputed according to the speed limit formula at the beginning of this section. It continues movement for the remaining time with that speed. In other words, Permitted_dist is reduced to Distance_moved + New_max_dist * (1.0 - Movement_time_used).
  • otherwise, if Hull_tech < HullTechNotSlowedByMines, the ship's Permitted_dist is reduced by 10 ly. For example, a regular ship moving at Warp 9 has a Permitted_dist of 81 ly. The first mine hit reduces that to 71 ly, the second one to 61 ly, and so on.
