Moving Target

[jgsugden]

Wow, I never met someone who could shoot 100% at skeet and trap. This I would like to see.
Trivial physics exercise on paper. Rather more difficult in practice.

Have you ever seen someone that hits skeet and trap targets at approximately the same accuracy that they hit stationary targets of equal size? That is the more appropriate comparison. And I know people that are about that acurate when dealing with a target moving at a predictible speed and vector.

A clay pidgeon moves at about 45 MPH. That is about 400' per round in D&D terms. You might give that a +1 circumstance bonus to AC, but I doubt that the game will be well served by that level of detail.

This is one of those situations where we could argue for a few weeks, come up with slightly different models to cover the situation and put into place rules that have a trivial effect on the game. Or, we could just say, "The devil is in the details ... speaking of which, my time could be better spent designing a cool encounter with a Cornugon." Worrying about this trivial detail is too much micromanagement.

If you need a game that perfectly duplicates reality, I suggest taking a bamboo stick to the local zoo, climbing over a fence and whacking a bear with it. That should give you a realistic violent game.

d20 Modern Uses Vehicle speed Modifiers.

Speed_____AC Bonus___Attack Modifier
0-100'_________0_________0
101-250'______+1_________-1
251-750-______+2________ -2
751+_________+4________-4

Vehicles can't do double moves though.

If you use the above a Monk19/Brb1 (speed 100) would only get a Speed Bonus to AC when pulling a double move or charging more than 100'. I'd be lenient and give him the +1. He'd still be attacking with a -1 though.

As mentioned above, don't worry about it.

Oh so you've never patterned a shotgun before. At the range where you will be shooting skeet or trap, the shot pattern should be something like 18 inches. That's mighty close to the width of a torso. As long as the shot pattern overlaps the pigeon, it breaks.

A clay pidgeon moves at about 45 MPH. That is about 400' per round in D&D terms. You might give that a +1 circumstance bonus to AC, but I doubt that the game will be well served by that level of detail.

Gee, and that shotgun fires it's shot at around 1200-1400 fps. How fast does your bowshot go? (I'll answer the question myself, since I don't expect anything useful based on prior performance). Hmmm, about 450 fps with modern bows. Gee if we do a ratio type of thing, we end up with that skeet lead being roughly comparable.

This is one of those situations where we could argue for a few weeks, come up with slightly different models to cover the situation and put into place rules that have a trivial effect on the game. Or, we could just say, "The devil is in the details ... speaking of which, my time could be better spent designing a cool encounter with a Cornugon."

Since I was asking the question after reading about super speeds of 8K MPH, the matter might be a touch relevant. What if the speedster is doing 400 MPH?

Though since you are expert at all things of physics, riddle me this- what would the lead be for a bowshot at 230' at a target moving at a 20 fps perpendicular rate. Don't use a calculator now. That wouldn't be fair. You have six seconds. Oh, of course you better remember that the velocity of the arrow is not constant, and will decrease with range.

If you need a game that perfectly duplicates reality, I suggest taking a bamboo stick to the local zoo, climbing over a fence and whacking a bear with it. That should give you a realistic violent game.

Or maybe I could come to the board and listen to snide comments from people who are very taken with their own lack of useful information. That might simulate a different sort of reality.

If you don't think the discussion is worth the time, then move on. Someone else already offered some useful information (unlike you) with the d20 Modern speed penalties.
