are their rules on difficulties for shooting a moving target

[tetsuoh]

as the topic says, been looking.

Nope but there are difficulty penalties for size. There are also situational modifiers the GM may assess as well. Do not forget cove modifiers as well.

You could say that dodging is movement.

MAP with running.

The only mods i see in any of the books based on target movement comes in space combat in regards to missiles/torpedoes and bombs.

Page 127.

Missiles, bombs and proton torpedoes: Missiles, bombs and torpedoes are physical weapons which deliver awesome firepower. However they are difficult to target. Their Difficulty numbers are modified by how fast a target is moving.
A ship going a space speed of 3/atmospheric speed of 100-150) has a +5 modifier.
A ship with a space of 4/atmos of 151-200 adds +10
A space of 5/atmpos of 201-250 adds +15
and anything from space 6 or atmos of 251+ adds +20.

The only OTHER spot you see about target speed modifying a to hit roll is in the MTFAS (multiple targeting and frequency acquisition system) of Storm troopers helmets, adding a +2d to their blaster skill to hit targets going faster than 10m a round.

I really just counted this as one of the many things a GM was supposed to take into account when setting the difficulty number.

There is also the question of heading. A target moving towards or away from the shooter will not be as difficult to target as a target moving laterally across the shooter's line of fire. The relative lack of lateral movement will make calculating lead somewhat easier.

Personally, I've never liked applying the target speed penalties just to missiles and bombs, as their short effective range seemed penalty enough. I'd rather take those difficulties and apply them more generally, like so:

Target Speed = To Hit Difficulty Modifier
Stationary or Cautious = None
Cruising = +5
Full = +10
All-Out = +15

-5 if the Shooter is in the Target's Front or Rear Fire Arcs.

It's not pretty or perfect, but it works...

I think that "in the front/rear fire arc" needs some more thought.

Its's perfectly possible to be travelining perpendicular to an enemy and still be in his front fire arc.

It sounds like the rule makes the assumption that the weapons are mounted on some kind of mobile platform (a ship/vehicle) and that some of them are mounted port or starbord.

Also, the rule seems to assume that shooter and target are the same scale. "All-out" for a turtle would make no difference to a targeting system (even human eyes, in this case) that is designed to engage targets moving at higher speeds.

I think that the penalties are probably good as is. I just feel that given that scaled weapons have fire control systems, we run into some weird scenariios. I actually feel that this question raises another issue with regard to the RAW scale system, and why I think that opponents of different scale should have targeting restrictions placed on the fire control systems (the system just doesn't "register" targets below a certain scale).

Here's an alternate idea, using the 2R&E Speed Modifier Chart from Torpedoes and Missiles:

Space / Atmosphere Speed Range* = Fire Control Penalty
11-20 / 400-799 = -1D
21-30 / 800-1,199 = -2D
31-40 / 1,200-1,599 = -3D
41-50 / 1,600-1,999 = -4D
51-60 / 2,000-2,399 = -5D
60+ / 2,400+ = -6D

Additional -1D penalty if the attacker is firing at the defender from the defender's Left or Right Fire Arcs.

*This number is the total Move per round, not the Base Move. For instance, an A-Wing moving at All-Out (Base Speed of 12, times 4 for All-Out) would move up to 48 units in one round. That speed falls in the 41-50 group, so any Fire Control attempting to target the A-Wing would suffer a -4D penalty.

To use a film example, the TIE Fighters attacking the Falcon in ANH were "coming in too fast", flying at 20 SUs/round (Space 10 x 2 for Full Speed), which imposes a -1D penalty to the Quad-Laser's Fire Control on the Falcon.

I intentionally designed the chart with insanely high numbers because some of the ships on the upper limits of speed actually get that fast at All-Out. The Plexus Droid Vessel with a Space of 15 just barely misses the 60+ range, while the Storm IV Cloud Car tops out at 2,080 meters per round at All-Out.

Of course, the upper range Fire Control penalties can only be used at All-Out Speeds (no evasive maneuvers allowed), and the player will need to weigh the benefits of using pure speed to evade attacks as opposed to performing evasive maneuvers.

I'm on the relative speed already. It would be a variation on the chart from above, but with the speed calculated by the combined velocities of the two ships. For instance, an A-Wing in a head-to-head with an Interceptor at Full Speed would have a combined velocity (in space) of 46, which would generate a bonus that each would apply to their Dodge rolls.

If, however, the A-Wing was on the Interceptor's tail, the Speed difference would be negligible (-2), thus cancelling out any bonus or penalty. I did something similar for my ASC system, and I have some free time today, so I will probably be working something up for it.
