Title: [4e] Hitting a bullet with a bullet?
Post by: MajorTwitch on <11-26-13/0011:58>
Just wondering if their are any rules or collection of rules that says it is possible. Or is this just up to your GM say your character is cool enough to try such a thing.

If it is allowed what would be the modifiers? You are at least looking at a -6 dice perceive the bullet and -6 to hit it due to size.

Its a simple Edge(10) roll. No exploding 6s though.

There are no rules for it, because stuff like this just isn't possible.

You could just say 'no'.

The closest you get is either catching thrown objects, or Way of the Samurai allowing you to fluff a defence bonus while holding a melee weapon (blade?) as deflecting bullets. From there you could probably come up with your own adept power or some SOTA cyberware / sensor / tacnet combo that allows you to add a firearms skill to your dodge pool vs thrown / fired objects if you also expend ammo as a Full Defence action. Not against anything coming at relativistic speeds, explosions, etc as common sense dictates.

Maybe for an unaugmented human. But it is the future! We currently have point defense systems that can track and destroy missiles and artillery shells. Why that couldn't get downsize and applied to a drone or a person with cyberware does seem like to much a stretch.

Something else... the EFA VARIANTS, which is an aircraft out of mil spec moves at speed 2000. So that 2000/3=~667 meters per second. As reference point 45 apc moves around 200m/s while a 50 bmg moves around 900m/s. However, nothing is stopping you from shooting at the EFA. You can hit an object traveling 3x faster then a bullet but not a bullet...

Even with top augnmented reaction and reflexes, a bullet simply moves too fast.  This is not considered to be remotely possible in Shadowrun.  And yes, it does seem like too much of a stretch to apply point defense principles to something with the speed and size of a bullet - keep in mind that the size of an object sets the margin of error for how far off you can be and still hit it, and that that margin basically doesn't exist for a bullet.

Source?  Also, "batted" is different from "shot" - if I remember right, there's an adept power for missile parrying to begin with, though I think it's limited to slower projectiles.

care to REALLY think about that twitch?

Most anti-ballistic systems engage the target at a range of 25km, And are themselves ballistic missiles (see Patriot missile system). For close in Point defense ships rely on the Vulcan mini gun firing 6000 rounds a minute, but even they require over 10km to lock on and track the target.


At typical gun ranges for 100m or less (for urban engagements), and velocity average of 1300f/s (291m/s) you are talking about .3331 seconds to impact... faster then the time needed for your brain to process that you are in danger, and even LESS time then it would take for you to line up a counter trajectory angle (keep in mind, bullets don't fly straight, they arc through the air) and pull the trigger.


IF you absolutely insisted on trying, and Edge(10+) test is very reasonable for such an unreasonable action. Oh, and if you missed? Go straight to the soak roll, no reaction test to get out of the way (you forfeited that with your shot)

Like I said before that - Way Of The Samurai.

I wouldn't work from the assumption that you are noticing and taking out a bullet mid-flight. That is unreasonable. Consider that the defender works from muzzle direction, expected recoil, average speed, etc to predict where bullets are going to be.

Very true. But the year is 2070, and technology does seem to advance at a exponential rate. One great example is the physical size of 1gb computer memory.

Now explain some of the aspects of this character that was I thinking about attempting this with:
It is like a 450bp with an 180 karma go with it.
Now I get this may not be completely legal, but it was within reason of rules and most of it has been okay by my GM. Unless there are some rule(s) that I missed that would says this is blatantly impossible, we have yet to find them.
So the rest of the madness:
*The character is technomancer with a 8 resonance, with the echoes: Biowire, and Acceleration (I may need three ranks of acceleration instead of just one)
*Acceleration: "This advanced echo reinforces the technomancer’s neural structures to accelerate his neural pulse rate, decreasing the amount of time required for an electric signal to traverse the distance..." the electrical pulses that control can the body are moving faster, enabling faster action.
*Next you make rating 16 sprite (I think our GM set a limit on them to 2xRes which I don't think exists by book rules?) have in a comlink that is connected to your biologic PAN, and give the sprite control over the biowire in the body. If the body is controlled with electric pulse how is that much different then a drone? The machine sprite just needs autosofts.
*Sprites: "A sprite’s Matrix attributes are independent of the attributes of any node in which it is running.it runs on other, inexplicable resources." so it should be still rating 16 even in a cheap comlink?
*With modified Radar Sensor (didn't see why you couldn't modify cyberware) boosting the signal to 4, so 1km field of data collection, you have the power of a rating 16 sprite to perceive the bullet with electromagnetic radiation and electricity to move, both of which are faster then the bullet.
*With the right autosoft the sprite that is rigged into your body should have like 32 dice to shoot that bullet.
*I know that sprites have tasks, not so much worried about that.

...  You know, without getting into the rest of it, precisely HOW do you plan to SURVIVE compiling at Rating 16?  That twice Resonance limit IS in the rules, and at a rating past your Resonance the Fading becomes Physical; your plan will kill your character.
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: MajorTwitch on <11-27-13/0619:56>
"For compiling, decompiling, or registering a sprite, the Fading DV equals twice the hits (not net hits) generated by the sprite on the Opposed Test. This applies whether the attempt is successful or not. If the sprite’s rating is greater than the technomancer’s Resonance, the damage is Physical rather than Stun."
So worst case would be 32 and or 64dv, and that would be death. Compiling 16*2*.33=10.56dv  - average hits to resist 16*.33=5.28 for a net average of 5.28dv p. Registering 16*2*2*.33=21.12  - average hits to resist 16*.33=5.28 for a net average of 15.84dv p. Have 6 body, 11 boxes, so real death is 17+ boxes so on average survivable.

If I remove the exaggeration for effect, the statement is that it has a very high probability of killing you - far, far higher than you should be comfortable with.  There's a reason why the vast majority of players get very, very nervous about summoning or compiling past about 9 or so.

Yeah, had not done the math on surviving the complying process in some time. Much safer to keep the rating at 10 to 12. I think part of the reason that I had r16 sprites, was the party has crazy ideas of trying to kill a dragon in combat. If making the sprite didn't kill me a dragon would lol.

You have to go fully outside the rules for this.  Technically, it's not explicitly permitted - but even the closest match doesn't permit for it with projectiles of that speed.

That's pretty much flat out - the technomancer is not a device; their body as a whole does not interact with the Matrix even if it does interact with some Resonance abilities, only the bionode is at all connected to the Matrix.  The only possible way I can see to rig a body, and this is DEEP into grey area, is to have a Technomancer use Mind Over Machine to jump into someone's Move-By-Wire (as Mind Over Machine lets you jump into a device as if it had rigger adaptation, and a Stirrup Interface is "basically a Move-By-Wire system with rigger adaptation"); sprites cannot even get to that except possibly free sprites.

A biowire is close-ish to skillwires, but they're not at all the same - and skillwires alone wouldn't, even in the greyest of cases, get you to what you want, nor would a sprite that you'd be able to compile.

And, frankly, I don't see a sprite pulling this off on a drone - sprites aren't really distinctly faster than a Sam with Wired Reflexes 2, an Adept with Improved Reflexes 2, a rigger in Hot Sim VR, or a mage with 3 hits on an Increase Reflexes.  They're not appreciably faster in combat than anyone else is regardless of Rating; they might win Initiative and go first, but they can't act or react with greater speed than anyone else.  The fastest you can get is 5 VR passes, but that's available only with specific augmentations or echoes.

Rig into to the technomancer body was poor word choice. Sprite are similar to agents and agents don't need a rigger adaption to run a vehicle. To me the question is how is the biologic PAN and the brain connected? You can take real damage from black IC, it would seem there would some sort of direct connection.

A biowire is close-ish to skillwires, but they're not at all the same - and skillwires alone wouldn't, even in the greyest of cases, get you to what you want, nor would a sprite that you'd be able to compile.
Wasn't even sure that I needed biowire. The technomancer is not going to be rigged into per say, it more like giving up control of part of brain to sprite control. Adhering to provided rules would require mostly like require a Stirrup Interface that sprite uses.

And, frankly, I don't see a sprite pulling this off on a drone - sprites aren't really distinctly faster than a Sam with Wired Reflexes 2, an Adept with Improved Reflexes 2, a rigger in Hot Sim VR, or a mage with 3 hits on an Increase Reflexes.  They're not appreciably faster in combat than anyone else is regardless of Rating; they might win Initiative and go first, but they can't act or react with greater speed than anyone else.  The fastest you can get is 5 VR passes, but that's available only with specific augmentations or echoes.
Not sure why you think that. "A Pilot program is basically a System program with extra features, and so is used whenever the drone’s System rating would be. It also stands for a drone’s “Mental attributes” when called for (usually Intuition and Logic, and sometimes Willpower)." So that sprite could have 16  Intuition and Logic, that would make them insanely fast?

1) What you're talking about isn't achievable.  The damage Black IC does is bio-feedback, which has nothing to do with the interaction between the bionode and the body - bio-feedback hits mundanes just as hard, if not harder (depending on the Technomancer's Charisma).  The bio-node is not the brain; it is impossible to go from the bio-node to the brain.  This is important and made sufficiently clear in Unwired.

2) That is not possible.  At all.  The closest possible way to achieve something like this involves having or somehow mimicking the Stirrup Interface, which would require 'ware and a specific Echo, and even then it's very grey area.  There is no possible way to go from bio-node to brain.  What you're looking for, basically, is a technomancer analogue to Possession spirits, which simply doesn't exist (and getting it would involve giving up other capabilities of your sprites, much like Possession Magicians cannot summon spirits with the Materialization power, substantially limiting how their spirits can operate).  As far as this goes, it's not simply a matter of the rules not existing; it contravenes how things work in-setting.

3) Doesn't change their initiative passes, so no, it doesn't make them faster (Initiative Passes measuring how much you can do in a given amount of time, and as such being the useful metric of speed here).  It has an impact on Initiative order, but does not allow them to compress actions into a tighter time scale than they would otherwise be able to do them in.

Post by: MajorTwitch on <11-27-13/1502:30>
1) Have page numbers where that is clarified in unwired? I either missed it or miss read it, most likely the latter.

3) I completely miss understood what you were getting at. Anyhow, so a combat turn is 3 seconds. You have 3 Initiative Passes so that is 1 action phase per second. You have take one complex or two simple actions. So that would be 0.5 second per simple action, which is pretty quick but not fast enough. But the rules do not state that simple action is necessarily 1/2 the time of a action phase. Could one simple action take 0.9 seconds while the another 0.1 seconds or for the matter does the action even use the whole second? My line thinking was with such high attributes the speed at which it could process tasks would be greater. Duo core process and quad core processor both could a task just a difference of time required.

Roleplaying Biological Node
Hacking
Having your b io -no de
hacked is an unpleasant experi-ence for any technomancer—it
is, in e ect, an intruder in your
head. Just as the biological node is not a normal “place” in the
Matrix, however, it should also not be confused for the tech-nomancer’s brain.The bio-node is a construct created and
maintained by the brain as an extension of their abilities. So while
a biological node can be hacked, this does not mean the hacking
technomancer can gain any control over the target’s memories,
thoughts, personality, or actions. Instead, hacking a bio-node is
more akin to attacking the root of a technomancer’s Resonance
abilities.

Page 136.  As an aside, the word "brain" occurs a lot in Unwired...

If we're looking at the duration of a Simple Action, because any two Simple Actions can be combined and they take the same amount of time as a Complex Action, we have to assume it's an even split.  Free Actions may take much less time.

If something took that large a share of a pass, it would be a Complex Action - and regardless of that, the travel time of a bullet is smaller than the space of the action at the absolute fastest - we'll call a pass 0.6 Seconds (considering specifically a character in VR with 5 passes); a bullet travelling at 291 m/s moves 174.6 m in that time; if we assume the Complex or 2 Simple actions are 0.5 seconds, that's 145.5m in the COMPLEX action you'd be trying to pull here, that's 67% of what are being tossed around as the outside of urban engagement ranges; it's 0.34 of a second to travel 100m).  Just calculating the trajectories would be an extended test; even if we give it the very fastest interval time (which wouldn't make much sense), you're looking at rushing the job from 3 seconds to 1.5 to 0.75 to 0.325 (assuming you GM even lets you stack rushes), and glitching if you get half (1, 2, 3, or 4).  In that space, you're looking for what would probably be assigned Hard or Extreme difficulty - you're trying to get 18 or 24 hits on one roll, and that's even before attempting to fire a bullet on the exact calculated trajectory.  And this is the sort of operation that multi-threading cannot help - you're performing a set of related calculations, so you'd need it to be a single thread or things just get worse.

If we take this to a sprite, and we consider this a Logic + Intuition Extended Test (1 Combat Turn, 18) - do keep in mind that 1 Combat Turn is the shortest possible interval on the table - a Rating 16 sprite will roll 32 dice for 10.67 hits per interval, requiring 2 Combat Turns to make the calculations.  In that time, the bullet (not factoring for deceleration) will have traveled 1.746 kilometres.

So current system point defense can acquire and destroy a target in 0.3 seconds. Not that matters so much, but making the sprite take an extend test to do something he was design for seems silly. Like having a calculator to find the answer to 3.75^324, but then you don't get to use the calculator. Yeah that would be insanely hard, the autosoft should be seen as tools or a like to lower the threshold. Or not even make a test, do you make extended test to shoot the size micro drone speeding towards you?
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: RHat on <11-27-13/1637:39>
A sprite wasn't "designed" for this.  Far as anyone knows, they weren't "designed" in the first place, and certainly not for any known purpose.

And why don't you link me to an article on those systems, then?
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: MajorTwitch on <11-27-13/1704:28>
By designed mean that you have chosen to compile a machine sprite and you have also selected its complex forms, that not sprites were created or designed for shooting bullets with bullets.

http://en.wikipedia.org/wiki/Close-in_weapon_system (http://en.wikipedia.org/wiki/Close-in_weapon_system)
Mmm its states 1/3 not not 0.3, still pretty fast at 0.33 seconds.
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: RHat on <11-27-13/1808:11>
Yeah, big frigging difference at play - much larger projectile to be intercepted, travelling a far, far, far greater distance (and probably more warning, given the need for acceleration time).  And they're not using 1 bullet, they're using a massive barrage of bullets.  It's really not a similar case.

Also, I feel I should point out:  It really isn't any more likely that technomancers create sprites than that mages create spirits - pretty much all the indicators are that they exist before you compile them, and they go on existing after you dismiss them.  And there are no complex forms available to select that make a Sprite a perfect match to this.

Why I brought it up was proof of concept. A musket and 50cal browning machine gun are both firearms with year of technology between them. However, one is far better of a weapon then the other. And I could get a mini gun to have 15 rounds down range per action phase.

Rereading the text on sprites: the first lines says you create them. Now will give you that they have in parentheses another school of though that sprite might be like spirts. Machine sprites have optional complex form of autosoft any. So that should allow you to tailor them to the job as they one extra complex form per 3 force it has.

Post by: RHat on <11-27-13/2006:34>
The whole idea of simply creating sprites isn't really compatible with everything else that's around about them.  Sprites exist in the Resonance Realms independently (perhaps even having some sort of society - in one place, they're even fighting a civil war), some of which show signs of significantly predating technomancers, otaku, or even the Sixth World (the Endless Archive, in particular, goes back to the invention of computational devices, and depending on the definition you're using that's very damn far).

Basically, certain streams - Cyberadepts and Dronomancers in partiucular - think of sprites as their creations, but overall they don't seem to be correct.  The default stream presented in SR4A is the Cyberadept stream, so the text tilts towards that.

And Autosoft any requires the autosoft to exist - even checking War, there is no autosoft for anything remotely close to this.
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: MajorTwitch on <11-27-13/2123:06>
What autosoft do you think would be needed? To me that default list seems to cover everything needed. There are rules for coding your own software is that only book stuff at a selected rating?
Title: Re: [4e] Hitting a bullet with a bullet?
Post by: RHat on <11-28-13/1913:02>
There's nothing applicable to the task of point defense as seen on CIWS - the closest thing would basically be suppressing fire in the area.

The Targeting Autosoft is made to make general combative use of the weapon; this would be outside of its parameters.  And I'll just state again:  You seriously overestimate how feasible this would be, and how related to the CIWS concept it is.

So still exploring the concept of sprite control. The biological pan is a construct of the brain, but to the two are not directly connected. If hacking the biological pan you are only interacting with the root of the technomancers ability. Bio wires are run with complex forms so would that mean that the bio wire is linked to biological pan? And if it treated like cyberware skillwire otherwise, would it be a device that is slaved to the biological pan and therefore accessible to a sprite.

So I am still not sure why you think that a clearsight and a targeting autosoft  would not do the job. They do not pose any limits of what can be perceived and targeting allows it to use the weapon. Use of weapon should include the ability to calculate target trajectory and use given weapon to hit target. I do not remember seeing: if target is size micro and moving fast you need more stuff to shoot at it. There could be combat rules that explain that I missed.

Now there is the missile defense system on 139 of arsenal. Has a firmware package to shoot missiles. Could a technomancer thread that? Not within the rules to have that as an autosoft? There rules for creating non book given software or programs?

Could bullets be easier to hit then missiles? I realize they have far less mass to hit but they also may move up seven times slower then a missile. Missiles can also change course, bullets may only deviate slight from their trajectory. Very predictable, I guess most point defense systems would not brother trying stop bullets because things they are mounted are not going to effected by them.

I just want you, RHat to know, I deeply appreciate you taking the time to answer my questions and work through the concepts. It is not that I  am overestimating the possibility of this, it is more about the creative challenge.

Skillwires, and thus biowire, would still be insufficient for this trick.  And you can't give a sprite activesofts anyways.  A sprite cannot control a person; it is simply not possible.  Technically, as it follows all basic rules for skillwires it doesn't explicitly alter, you could get a Machine Sprite to run Diagnostics and Stability in there, but that's all it could do there.  It's possible you might be able to use the skillsoft of a Tutor sprite, but then you're limited to Technical and Vehicle skills.

In any case, missile defense is not even close to the same thing.  Missiles, in this context, are inarguably an easier target - detected from a much, much greater range or at the very least with more time (due to acceleration; even if it is a supersonic missile it isn't leaving the launcher at that speed), and as you'll note even in Shadowrun the task can only be attempted with a laser or a fully automatic weapon.  It's still doing the same thing as modern CIWS systems are, at least when using bullets - you fill the projected path with as much lead as you possibly can, and just hope the missile happens to hit a few bullets.

The other thing about that missile defense system is that it's not just a matter of firmware - it also requires the extra large sensor array that can only be gained with the Improved Sensor Array mod, which means you're dealing with a sensor array notably larger than what the typical vehicle carries, and that's just to manage this with missiles; I'll repeat, that's a much easier task.

Could bullets be easier to hit then missiles? I realize they have far less mass to hit but they also may move up seven times slower then a missile.


A round fired from a 44 magnum handgun travels at 391m/s OR 1407.6km/hr  for the LIGHTEST load... or 460m/s (1656 km/hr)

A round fired from an M4 (5.56x45mm NATO) travels at 936m/s OR 3369.6 Km/hr

Now the average speed of a air to ship missile (since we are talking about CiWS systems) has a speed of 735km/hr all the way to 3000+Km/hr



The width of a .44 magnum round (the "fattest" round here and a good example of a heavy pistol round) is .43 inches the 4.46x45mm is less then half that.

The Width of the average anti-ship missile is .5 meters (1ft 7.5 in) to 1.4 meters (4ft 3.3 in) (for the fastest missile on record)


Speeds are similar.

Size different is MASSIVE. (and we haven't even talked about length),


Nor the fact that a CiWS takes up to 8 seconds to achieve lock on for a firing solution, which means the missile has to be deployed at ranges of  3km (for the slowest adjusted for safety margin.) to 10km (for the fastest, adjusted for safety margin)



In a gun fight in a urban setting, most engagements happen at ranges of 200 meters or less.... which means for more weapons, you are hit before you know you are under fire. Especially considering that the speed of sound is 343.2 m/s, means that the bullet has hit it's target before the rapport of the shot gets to the target.


There is no way to react in time to shoot a bullet with an other bullet in that time frame. when you look at the time needed to receive stimulus from the optic nerve to the brain, then the brain to process the danger, then sand a signal to the muscles, you are around .3 seconds (Providing of course you can see a 1.03cm object travelling faster then the speed of sound. AND, we have not even taken into consideration the time needed for your cyberware implanted computer (or threaded form) to process the speed and trajectory, compensated for gravity, AND factoring in your own weapon's trafectory, speed and compensating for gravity..... which, it you where lucky would be .1 to .4 seconds.


So now, you are looking at a response time of .4. to .7 of a second, and you are not even guaranteed to hit the target. meanwhile that bullet has traveled to you approximately 170.2m (If you react in .4 seconds) to 297.85m (if you react at .7 seconds) And that is for the 44magnum, using an averaged speed

If it was the assault rifle, in .4 seconds the bullet would have travelled 374.4m OR 655.2m if you reacted in .7 seconds.


Again, given that urban engagement happen at 200 meters or less... you hit with assault rifle everytime... and hit with the heavy pistol IF you are less then 171 meters from the shooter.


As said, physically it can not be done. And as Rhat points out, there is no cyber/bio or thread that allows you to either.

Not to mention that by RAW/RAI there is no mechanic for it either.

Which is why I suggested not doing it in that manner.

Have you not read the rest of the thread Reaver? At this point it is more of question if a sprite rigged into something could do it. Also you talking know it is coming: *With modified Radar Sensor (didn't see why you couldn't modify cyberware) boosting the signal to 4, so 1km field of data collection. That can see through walls, 360 degrees and detect things as slight as breathing. Those radio waves move at the speed of light, it just comes down to processing the data. Which I would like to think a rating 10+ sprite could do in under 0.1 of a second. With three Initiative Passes a simple action is around 0.5 seconds. So with slower rounds it is possibility if I understood your findings.

You say claim that RAW/RAI does not support this. But I yet to understand why. No where I have seen if the target is moving super fast you are no longer able to shoot it. You +3 dice (body size) to hitting a jet moving at 667m/s. So why can I not take -6 dice for bullet size and shoot? Or some place where they say shooting bullet with bullets is impossible. They did not say you could and they did not say you could not either.

Other musings... They never listed armor or body for a bullet. Shooting is not normally part of a defensive action so this could not used as interrupt action. However, if you had the higher initiative you delay action to shoot it?

aside from the fact that a bullet is too small to be picked up on radar?

IF the bullet could be picked up on radar, it would also pick up anything the size of a large housefly and bigger, which would totally scramble your radar anyways and give you dozens to hundreds of false positive signals.

As it stands, radar only picks up objects of 1 meter or greater, so they still get false positives off of large birds.....


Also, at a range of 1 km, it would be possible in theory..... but then you are talking about an even larger projectile (a pistol or assault rifle round, while in theory can travel this distance, it's accuracy would be so low, it would have to be aimed at a large target... like a vehicle. Which are already pretty immune to small arms fire... At personal target by RAW would be a -6 + dice pool modification.)


so again, at 1km,  for a missile sure, but a solid slug projectile? with such mass and velocity coupled with a VERY small cross section? nope. But you have improved your reaction time to about  1 to 1.4 seconds....

And note that the missile defense option itself requires for more than that for sensor ability.
