Partial Movement

Henrik · March 21, 2001, 05:38

In my scenario I have a road modifier of: 2.
When I enter 172 in movement for a unit (this would suposedly give it 1 and 1/3 moves) it gets 44 moves in the game, have anyone tried to give partial movement to a unit when the road multiplier is 2?

You can't do it with road modifier 2.

actual move=((r*move) mod 128)/r, where r is the road modifier, move is the move value in rules.txt.

Examples:
r=3, move=172, actual move=((3*172) mod 128)/3 = (516 mod 128)/3 = 4/3,
r=3, move=343, actual move=((3*343) mod 128)/3 = (1029 mod 128)/3= 5/3.

Since 128 is a motiplyer of 2, 4, 8, 16, 32, and 64, you cannot get partial move if your r is one of the above numbers. Unless, the game can read 1.5 from rules.txt.

With a total movement of 1/3 (Move 43, RM=3), what happens to the units?

Can they only move on roads and rivers? A unit down to 1/3 move point will typically not be able to move from a road square to a non-road square... but on the other hand units seem always to be able to move a least one square.
Which Civ-rule takes precedence?

Usually when you have a unit whit 1/3 movement left (happens when you walk on raod or river as you said yourself) you can sometimes move to a new tile and sometimes not, I would guess the chance of moving to a new tile would be 1/3 of the times.
This probably applies to a unit that starts out whit this many moves to.

One more thing. When playing Imperial Rome, a 5/3 move unit would have move 2 sometimes (which is greater than 5/3!), when it has lost some blood in battle. That's interesting.

It is not possible to get a third of a movement point when your road modifier is 2. If fact your can not get a partial movement factor with any number divisible by 2.

I hate to correct the mighty Xin Yu

but, the formula should be mod 256 not 128. The reason being that numbers between 128 and 255 produce a negative hexidecimal value resulting in a unit with no movement allowance at all.

I figured as much myself, but I had hoped that you guys would have found a way to do it...

Too bad, I really needed a unit whit 1 1/2 moves (sould have been called Rackoczy(a transylvanian duke who had his army drawn by oxes rather than horses making his troups very slow))
