The instantaneous velocity mid-journey actually makes interception hard and any combat last microseconds before both parties are out of range.
Still, most Traveller drives are powerful enough that the ships are operating at velocities greater than the escape velocity for that orbit (which is where the radius of the orbit tends to infinity), which means the ships are effectively operating in free space anyway.Īnd the standard constant acceleration assumed for Traveller spaceships makes actual combat only really viable at the start or end of a journey. Only Aerotech (Battletech) and ASAT have attempted to model this in a game. Jumpbreaker Missile: These missiles create localised gravitational distortions when they detonate, making the delicate calculations required for an accurate. Of course the really fun space combat starts happening in orbit, since the lower your orbit the faster you have to go. In effect, interest and bank financing cost a simple 120 of the final cost of the ship, and the total financed price equals 220 of the cash purchase price. effects of gravity on different bodies in the solar system is to calculate what your weight wound be if you were standing on their surfaces Scientists use kilograms to indicate the mass of an object, and it is common for Americans to use pounds as a measure of weight. uses a similar mechanism to Mayday to calculate drift, by referencing where you were at the start of the turn with where you are at the end. Mortgage or Debts: If the crew are paying off debts on their spacecraft, then these debts must be paid each month.The standard terms for a ship mortgage is paying 1/240th of the cash price each month for 480 months (40 years). includes facing and the fact that thrust can only be used to move you forward. Used a 12 impulse type system that was nicely adaptable to Traveller's mechanics. Note that the table gives distances in km, so you've got to tack on three zeroes to end up in meters.One of my favourite hex-based vector movement space combat board games was Shooting Stars by Yaquinto. I guess it all comes down to whose cultural influences shaped your games. (G is rounded to 10 m/s 2 for ease of calculation. Written to be compatible with Cepheus Engine and other classic 2D6 based science fiction games, this product gives you lore to share with players about the onboard gravity systems. Where \$t\$ is measured in seconds, \$d\$ in meters, and \$a\$ in meters/seconds 2. Gravtics: The New Spaceman, is the ideal guide to artificial gravity for a new Spaceman. Roll 2D for the specific Hex (this random selection will not locate any of the. Roll 1D to determine (1-2-3) Black or (4-5-6) White Numbers. When calculating damage, the standard rules in the rule book apply, so roll for damage, deduct armour, multiply with effect.
The formula that produces the above times is: From my reading, Step 10 (Random Places) kicks off how to identify the various hexes with the graphics at the very bottom of the page (which seems to me for use with world, terrain, and local hexes). origin) in the table above is roughly 1 million m/s-approximately 1/3 of one percent of c-so we're comfortable sticking with classical calculations. The greatest veloticy thus attained (w.r.t.
If you want to play the game, get the Mongoose version. Any 'rounded RPG library' should comprise at least one edition.
This table is, indeed, calculated by assuming that a ship can produce constant acceleration away from its origin, instantaneously pivot \$180^\circ\$ at the midpoint of its journey, and constantly decelerate for the second half of its journey. Traveller is a classic and very much old school in its own right (Id include Traveller in my OSR but the D&D folks disagree).
