Hi Ivan,

The description in LBB2 can be a little obscure if you are not already very comfortable with vector addition. It really is basic vector addition as can be found in many a text book.

This site has a nice description of the basic concept:

http://www.glenbrook.k12.il.us/GBSSC...ectors/va.html


To your specific questions:
Quote:
So, can someone give a basic rundown of ship vector movement (book 2) for moving a ship at a steady pace, turning, and accelerating, respectively ?
For a steady pace, don't accelerate.

Turning, draw you current vector, then draw the longest vector you can in the direction you want to go, keep doing this until your vector is in the direction you want.

Acceleration, keep adding vectors to your current direction.

If you have a hex mat the Mayday approach, linked above I believe, does the same thing but you can ditch the protractor and ruler!

Finally the range band approach is very good and an even more accurate representation of actual movement if only two ships are involved. The reason being LBB2 and Mayday (IIRC) ignore the third dimension. With two combatants only distance matters, since a straight line can always be drawn between two points range bands (a straight line)are always an accurate representation. Of course if you throw in a planet all bets are off.

Heh, you know, when I saw this I had to wonder, do they even still teach vector geometry/algebra in primary/high school?

I use Mayday to teach vectors in high school.

allright. That helps clear up things. I'll have to break out the mini's or counters and play around with it a bit.

One quick bit of advice, you can skip the whole planetary gravity effects bit in my opinion, it'll simplify things a bit and you won't miss it. It never made much sense since Traveller ships seem to operate with an anitgravity effect that cancels out local gravity.
