Rolling Barrages in FWW

[Volcano Man]

In the second line of my example above, the Barrage has a duration of 6 turns and it moves a total distance of 12 hexes during that time period. I deduce from your explanation that the Barrage will move forward 2 hexes each turn until the end time and end line are reached.

Correct.

The first line of my example is problematic, in that the Barrage only moves a total distance of 10 hexes during the same time period. How will the game engine handle this situation? Will it linger at the start line for 2 turns and then move forward at a rate of 2 hexes per turn, will it stall during one of the intermediate turns for 2 turns and then continue forward, or will it progress forward at 2 hexes per turn and then linger at the end line for 2 turns?

Well, in that case it will round off. So, in the eample, what you end up with is 1.67 hexes per turn, so essentially in some turns it may move forward one hex and in another turn it might move up two hexes (depending on the decimal). Specifically, in the example, it will move forward two hexes in turn 1, then one more hex in turn 2 (3.33 total), then two more hexes in turn 3 (5.01), then two hexes in turn 4 (6.68), and then one hex in turn 5 (8.35), and finally two hexes in turn 6 for the total of 10 hexes. I could have made a mistake with the math but hopefully you get the idea.
