      public Engine(int engineRating, int engineType, int engineFlags)
      The constructor takes the rating of the engine, the type of engine and any flags. Engine ratings are divided by the weight of the mek to get they walk MP.
      Parameters:
      engineRating - the rating of the engine
      engineType - the type of the engine, either combustion or a type of fusion engine.
      engineFlags - Wether the engine is a tank engine, a clan engine, or large engine, or any combination of those.

  • Method Details
