Well, the first obvious answer is that Velocity will determine Active Defenses. Each point above/bellow the human average will grant +/- 1 to ALL active defenses, while imposing a penalty of +/- 1 to the active defenses of the adversary - therefore, it's the same as imposing a penalty equivalent to the difference of Velocity between the two, since the adversary will also be gaining/losing bonuses to his own active defenses. Example: V 12 vs V 11 V 12: active defenses +2, adversary active defenses -2 V 11: active defenses +1, adversary active defenses -1 V 12: if Dodge 8, final Dodge = 8 +2 -1 = 9 V 10: if Dodge 8, final Dodge = 8 +1 -2 = 7 This is realistic, giving faster fighters better reflexes and making them harder to predict. Does that mean that it's basically impossible to defend or hit a super speedster with V1000? YES! Absolutely! A Speedster with V1000 acts once every 0.01 seconds! This mean that such a super takes 100 regular actions in a single second! You SHOULDNT be able to even see his movements, let alone be able to react to those! Now comes the harder part, because the purpose of all that math is to allow a compreensive set of actions; for example, if a nornal human (V10) is (trying to) fight a Speedster with V1000, the Speedster should hit 50 times, the normal human would finish his one action, and then the Speedster would launch another 50 attacks and only then would a new turn begin, in that exact sequence. Now, in order to simulate that, here's what we are gonna do: Take the Reaction Time (RT) of each person involved in the action. Reaction Time is always 1/V. ExampleFighter A - V11 = RT 1/11 Fighter B - V12 = RT 1/12 Fighter C - V13 = RT 1/13 Fighter D - V14 = RT 1/14 Fighter E - V15 = RT 1/15 Now we find the Least Common Multiple (LCM) in order to place all of those under the same divisor: LCM 11, 12, 13, 14, 15 = 60.060 And now we apply that to all the fractions: Fighter A = 5.460/60.060 Fighter B = 5.005/60.060 Fighter C = 4.620/60.060 Fighter D = 4.290/60.060 Fighter E = 4.004/60.060 We can just simply eliminate the divisors for all now: Fighter A = 5.460 Fighter B = 5.005 Fighter C = 4.620 Fighter D = 4.290 Fighter E = 4.004 This gives the amount of "ticks" that each of this fighters take to complete a single, regular action; therefore, the faster the fighter, in less ticks he completes his actions, therefore the lower this number, the better To know what amount of "ticks" correspond to 1 second, use the "control" parameter of an average human of V10, in this case: V10 = 1/10 = 6.006/60.060 = 6.006 ticks/second. Now comes the action sequence; "Fighter E" goes first with 4.004 ticks, followed by "Fighter D" with 4.290 and so forth. Now gets the sequence of actions. For a quick table between "Fighter E" and "Fighter A to compare how would that play out, and the table of 1 second "turns": Fighter E4.004 8.008 12.012 16.016 20.020 24.024 28.028 32.032 36.036 40.040 44.044 48.048 Fighter A5.460 10.920 16.380 21.840 27.300 32.760 38.220 43.680 Ticks per Second6.006 12.012 18.018 24.024 30.030 36.036 42.042 48.048 Now, we those tables it gets easy to determine the order of actions of each fighter: Fe(4.004), Fa(5.460), 1s(6.006) Fe(8.008), Fa(10.920), Fe (12.012), 2s(12.012) Fe(16.016), Fa(16.380), 3s(18.018) Fe(20.020), Fa(21.840), Fe(24.024), 4s(24.024) Fa(27.300), Fe(28.028), 5s(30.030) Fe(32.032), Fa(32.760), Fe(36.036), 6s(36.036) Fa(38.220), Fe(40.040), 7s(42.042) Fa(43.680), Fe(44.044), Fe(48.048), 8s(48.048) So, to make a clean table, the order of actions would be as follow: Actions per Seconds - E / A s - E / A / E s - E / A s - E / A / E s - A / E s - E / A / E s - A / E s - A / E / E Meaning that in this small interval of 8 seconds, Fighter E will have acted a total of 12 times, while fighter A will only have acted 8 times. Now, obviously all this math is impractical to be done with paper and pen in the middle of play, hence my problem. A friend of mine said he's willing to make an app for that, so the idea is that you just place each person's Velocity and the app gives you the final actions per second table, but I dont know if he'll do it. This can also be done on Excel I suppose. Im trying to learn how to make an app, but I dont know if I can do it. Anybody would be willing to land a hand? It's for a good cause...

 06-29-2022, 03:50 PM #3 Varyon   Join Date: Jun 2013 Re: Turn of Combat Reformulated - Velocity So... is the idea here to basically break up the turn into shorter time periods, with characters who operate at super speeds being able to take their "turn" multiple times in a single second, possibly with what they do on their turn influencing how long it takes before they get another (so if you punch - or do a thrust attack - your next action becomes available sooner than if you took a swing)? I've explored the idea before, and it honestly ends up too complicated to honestly use in play, even with a spreadsheet program to keep track of things (also, it typically requires a spreadsheet program to keep track of things). But you can see some of my previous attempts here and here. Humorously, I still have an almost-complete third version that's a bit more simplified (actually, a lot more, enough it might even be usable at the table), based on my Combat Posture system (specifically, using the Maneuver Points there), in limbo on my blog (but only the part I can access - I never published it). I got stuck trying to work out how to properly handle rapid fire weapons (the bane of any such system) and never resolved it, so it's been there for a few years now, honestly, and probably isn't going anywhere anytime soon... __________________ GURPS Overhaul

Yes, that's the idea, and yes it needs a program to help. I was hoping to have an app, it would be far simpler, a friend of mine said he can make an app but have no idea about the math on it, so I did the math. That friend of mine is brazilian too, but he lives in a boat and he's now in French Polynesia, I'll give him the link of this and see if he can make good of his word.

An app would be the easiest, and you would only need to push a button to show the results, a spreedsheet would be kinda polluted but still manageable.

Take a look at my previous post, I had reserved it to edit with all the math needed, the work is all there and the only part a little harder is to actually make the damn sheet. After it's done thou you just place the Velocities and (hopefully if it's everything right) it already gives you all the action orders and even the modified active defenses for everybody

Just check me second post in this thread

Bah, yes, I forgot the exact name of the advantage at the moment, so I called it "Super Speed"... I'll edit it

The problem of Altered Time Rate is that The Flash doesnt do 50 billions of actions, then the Batman throws a single Batrangue, and the Flash does another 50 billions actions in 1 second.

With Altered Time Rate, the Flash does a single action, then Batman throws a single Batrang, and the Flash does 99.999.999.999 actions afterwards.

Also, unless you also buy ungodly amounts of Enhanced Defenses, you can have Altered Time Rate 5000 that you'll be just as easily to hit as the next guy, and you need ungodly amounts of combat skills to mimic being easy to target a "slow moving" (from your perspective) target, in order to take insane levels of Deceptive Attack, tanking insane levels of skill penalty to nullify the active defenses of your adversaries. That's not exactly how it goes.

The way I built it, you'll actually have an easier time hitting and avoid being hit the faster you are, like a real Speedster.

But that not for Speedsters only, even small changes within human ramge would have an impact. And you can buy the trait in the order of 0.01 apiece; for example, having Velocity 11,24 is slighthly faster than 11,07, and it would be calculated at full by the program (just as an example, Velocity 11,24 would be 1 action every 0.890seconds whike V 11,07 would be 1 action every 0.903, a difference of 0.013 seconds more or less. Now compare those to V 11 full, which is 1 action every 0.909 seconds, and you can note the tiny differences between each fighter)

Honestly, if this is done into a program, the only inconvenience is having to put the Velocities into it. Since all speeds will be a function of "ticks", anything faster or slower would simply increase or decrease the amount of ticks, which the program would automatically adjust; that would include Rapid Fire, so in the example of my Fighter E above with 4.004 "ticks" per action, lets assume that some Rapid Fire weapon is 10x faster than a punch, then his ticks acount would drop to 400.4

Ideally, this would all be invisible to users, you would just place your Velocity, than there would be a buttom for each different action - so for instance, if a Swing gives +10% in speed (meaning it's slower), my example above would go from 4.004 to 4404.4 ticks for the next action, which the program would calculate automatically, adding that value for the next roll of action of the player or NPC; if it's a Rapid Fire, the player will just press the "Rapid Fire" buttom and his tick count will be added by the system on rounds of 400,4 each (meaning the player would should 10 times before any other act).

The only problem I always had is that I dont know programming :)

The issue with rapid fire weapons in a system like this is that, by its nature, you're breaking things up into fractions of a second, meaning each bullet fired should be its own action... but realistically, rapid firing a weapon and firing a weapon a single shot at a time are two very different actions. But it's not right to have someone fire a full second's worth of bullets in a single instant (if you have a foe who gets to act 40 times in a second, and you're shooting at him with a weapon that has RoF 10, he should get four actions per bullet that is fired, rather than getting 10 actions, then having a barrage of bullets come at him, and then taking his remaining 30 actions). So how do you handle it? That's the sticking point I couldn't really get past. Having the character roll once for all the bullets that second when he starts firing (like with the GURPS default) either means other characters' actions during the turn have no influence (making it function as though all the shots were fired in an instant) or they have too much influence (as the firer can't adapt to what their doing, like a real shooter - particularly one with good reflexes - could). Assessing each shot as it happens either gives the shooter too much control (they're basically shooting as though they hadn't just let loose a bullet a fraction of a second ago) or too little (you'd need to use mounting penalties based on Rcl to avoid the shooter having too much control, but those rapidly get to the point where the shooter might as well be shooting at the moon). If you've got a good solution to that, I'd love to hear it.

 06-30-2022, 12:04 PM #10 Curmudgeon   Join Date: Sep 2011 Re: Turn of Combat Reformulated - Velocity The first issue I have with Velocity is that the game slows down to a glacial pace if the velocities are too disparate. If you were to insist on resolving each of Flash's 500,000,000 actions first, the Batman's player is going to be waiting 13 years to declare his action (assuming you can resolve 1 action every second and don't do anything else for 24 hours a day, 7 days a week). If you're not going to resolve things action by action, then Velocity isn't needed and whatever you're using for a more rapid solution is the solution you're looking for. For Velocities where the differential is 2:1 or less, a difference of exactly 2:1 is easily resolved as 1 level of Altered Time Rate. For a ratio less than that, it seems that Initiative by Speed should be an adequate solution. Granted nobody gets an extra action in, eventually, but at GURPS resolution, it seems like much work for little gain. Taking longer with a swing action than a thrust action is perhaps more easily dealt with as a house rule that penalizes speed when swinging as opposed to thrusting, say something like "declare your attack as a swing at your usual place in Initiative, but roll for success at Speed-0.5 in the Initiative list (roll a die to resolve order if you're tied with anyone at that Speed)."
