Title: What's with the dual wield hate?
Post by: Dooz on February 28, 2012, 06:49:47 pm
Before you try that "not historically accurate" nonsense, consider every other aspect of the game. Then ask yourself what possible grounds could you have for deeming dual wielded weapons less "realistic" or "accurate" than leaping fully plated pike pokers from 3 inches, disorganized and nonsensical troops and battles, and all other manner of things that are what they are because this game is what it is, a game.

Now ask yourself, how freaking awesome would it be with dual wielded weapons, while I ask myself isn't this super possible with WSE? I imagine just making it exactly like having another 1her in the other hand controlled with the other mouse button would be all you need. No blocking, one swing at a time, maybe some sort of damage penalty for dual wielding like in most other games of this sort to negate possible op-ness, whatever other such nerfs and balances become necessary from observation like the rest of the mod. I probably personally wouldn't do it, at least not as a main, but I know there are plenty of crpg-ers who would.

If there is a legitimate argument against it, I'd love to hear it.

Well without blocking i dont see why anyone would use it. Just gonna end up being a lolclass like agi daggers

Agi daggers, which exist. You know people would use it, and having drawbacks is a good thing as any class should. Also, you can chamber, so it's not technically without any defense whatsoever.

Why wouldn't you be able to block dual wielding?

I imagine the reasons for no dual wielding is because you would need to make animations, balance it, and a whole lot of other nonsense.


If there ever was a dual wielding weapon/s I would hope that choosing which weapon you want to swing with could be decided by pressing the x(secondary) key.

Post by: Dooz on February 28, 2012, 07:52:29 pm
No block because how would you block using both mouse keys for attacks, plus it's part of hopefully balancing it to give it a disadvantage as mentioned. You wouldn't need new animations, just a flip of the existing animations, one on each side. Though the X alternate attack opens up some new options I hadn't considered, such as using that to activate the second weapon being only for blocking, giving you that option should you need it. So you can either go full on double swinging mental, or switch to a bit more defensive posture being able to block.

I'd love to hear a devs take on it and be told why it's impossible, that's what I'm asking for if reasons exist. It's just that WSE has made so many things possible, I can't imagine putting the same animations and mechanics of one 1her into two is out of the realm of consideration.

No dual wielding, it's unrealistic. A shield shaped like a parrying dagger would be kinda cool though.

Post by: Angantyr on February 28, 2012, 08:26:26 pm
People may be able to do silly things with weapons already in the mod but at least these with the exception of the lolhammer all have historical counterparts, so it could be a matter of consistency.

Personally, I'd not want the module to be more Hollywood-ish where every antagonist/protagonist absolutely has to dual wield, this is one of the few games where the fantasy elements have been kept at a minimum.


A parrying dagger would be nice, though yes, and was used in the renaissance.

Ignoring any other arguments, adding dual wielding would be nontrivial even with access to the game source. For the crpg devs, adding it would be a herculean task.

Why do you say it's unrealistic, if we've seen it in movies?

Regarding blocking, I have an idea: with each mouse button you attack with each sword, but when you press both clicks you block. Thus, you could attack with one weapon, or both (sequentially), and block when holding both buttons at the same time.

It actually is historically accurate. A whole mess of cultures and warriors have duel wield weapons in one form or another. It won't however work with this engine and this game. It won't work because either it takes away your ability to block or just functions as a shield.

It's okay from a realism point of view within the current borders of the mod (only if limited to dagger/1h combos though). But completely out of the scope of a mod like cRPG.


Actually, we could even introduce cloaks as usable 2nd hand weapons. The cloak and rapier fighting style fits in the mod's time period.

Post by: Angantyr on February 28, 2012, 11:41:44 pm
To judge by the to my best knowledge complete absence of support for this in the historical record it seems it has never been judged really effective by anyone.

But despite this it may have occurred of course, but never to a degree where it has been chronicled or evolved into a real fighting style.

There may also be proof of some obscure warrior monk or something using it somewhere, but I've never heard about it.

Since people post without reading the op, I'll say again here on the second page that "not historically accurate" or "unrealistic" are not valid arguments. Use google to find examples of it being used in history, and use your head ( :?) to realize that it's no less realistic than anything else that goes on in crpg.

It's okay from a realism point of view within the current borders of the mod (only if limited to dagger/1h combos though). But completely out of the scope of a mod like cRPG.

Meaning even if dual wielding was ever used, it wasn't during the "time period" of crpg? I'dunno, that seems like a pretty weak reason not to. How much stock can you really put into what time period all these random chaotic battles with all sorts of mishmashed troops are taking place in, and what does or doesn't belong, at least loosely? I think it's a lot easier to say guns don't belong for example, than using the weapons that already exist in a certain way. Doesn't seem like an irrefutable position.

Someone is making a dual wielding script for Warband as I type this, so not impossible.

However unrealistic if we stick to a certain time frame (and don't go and include some obscur African tribe into the mix)

Its a pretty good positon to exclude stuff from a time frame, otherwise we could end up with firearms and flak jackets.

Now for the first part, find me an example of dual wielding being used in the right time frame DURING A BATTLE, not silly civilian dueling, find me a proper battle where people used a weapon in each hand.

Just as soon as you find me an example of samurais fighting with morningstars alongside plated knights with katanas and every other combination of arms, armor, fighting style, aesthetic, etc. you wanna pick from a typical crpg battle.

My point throughout has been that any argument you can make to exclude dual wielding, is an argument you can make to exclude most other things from the game. And since that would leave nothing, we shouldn't do so. And if we're not doing so for any other aspect of the mod, why does the buck stop at dual wielding?

it is possible to make dual wield weapons such as 2 swords, you can still block with it. But it must become a shield while the weapon is 1 handed, and the shield needs a model from a sword.

Example:

But they all existed at one point, unlike dual wielding on the battlefield.

Though the technique of two-weapon fighting went out of style as single blade weapons and techniques evolved, it is still a central part of the history of fencing.  Two-weapon, or dual wield, combat was common in the late Middle Ages and early Renaissance period in Europe.  There are a number different weapons that were wielded in the off-hand.  The Main Gauche (French for left hand) was a small parrying dagger, while the notched sword breaker was a longer dagger that was designed to catch the blade of an opponent’s sword.  There are several myths about heroes and warriors wielding two swords of equal size, but these are often exaggerated, as a consistent technique for wielding two heavy weapons just doesn’t exist.
Though modern fencing is now based around a primary weapon, there are still a few fencing schools that allow the use of two weapons.  The main exception is Japanese kendo where two weapons of different size are still allowed in competition; though this is rare.
http://www.medievalweaponinfo.com/medieval/58-two-weapon-fighting/ (http://www.medievalweaponinfo.com/medieval/58-two-weapon-fighting/)

That being said, lets not pretend to know what exactly did or didn't go on on a medieval battlefield hundreds of years ago, or that crpg is a medieval simulator. Realize that we're not talking about adding new weapons that did not exist during a certain time frame, we're talking about using some existing weapons in a certain way. By what authority can this be proven impossible? Not very popular, not practical, not the best idea in the world, fine. Who cares? It's crpg. Look around you. Most of what goes on fits the bill. Doesn't make it impossible.

So if we're not talking about adding new weapons, and only a gameplay mechanic, then lets talk about some other gameplay mechanics that are not historically accurate or realistic. No matter how much you train, you can't make your shield less likely to break through sheer force of will or cover more physical space around you. Get rid of shield skill. No matter how hard you train, you can't force yourself to resist more blows to the head and survive, get rid of ironflesh. People in heavy armors should not be able to jump, or move nearly as fast as they do compared to others, slow them down greatly. What examples in history do we have of lone pikemen jumping through the air and stabbing an opponent in the face from mere inches, do not allow pikes to connect unless they are as far away from the target as realistic to do so. There are more, because this is a game.

And just for fun, here are some intelligent people discussing the topic on a relevant forum.

Forcefield of the shield represents the skill of the user to move his shield around to block stuff.

You could technically keep your shield in better condition the more you're used to it, just knowing how to angle it to reduce the stress of the blow, kinde stretched, but you're ok with that, right?

As for all the thing about armor: http://www.youtube.com/watch?v=NqC_squo6X4

Watch, learn.

I wish with all my heart that they fix the pike.

Its a medieval combat simulator with a bunch of of different factions and its got video game limitation, doesn't mean you should add stuff that was there ''just because its cool''

Title: Re: What's with the dual wield hate?
Post by: Paul on February 29, 2012, 10:43:35 am
Wat? I'm pretty sure someone with a lot experience with fighting with a shield can prevent damage to it to a certain degree with adjusting the blocking/parrying angle and thus deflecting a blow instead of letting the shield be hit frontally. Same for the increased coverage for someone with automated shielding reflexes.

The ironflesh skill can be interpreted like knowing how to "brace" oneself or doing minimal dodging to minimize the damage from an impact just like a boxer who can take a would-be knockout blow with relatively low damage if he sees it coming. Although then the ironflesh skill should probalby not be active when getting hit from behind.
Title: Re: What's with the dual wield hate?
Post by: Dooz on February 29, 2012, 10:47:16 am
So we can interpret anything we want in any way we want to justify it, just not two weapons in two hands. Can we just admit it's a personal preference issue at this point and nothing to do with accuracy or realism?

Post by: Paul on February 29, 2012, 10:58:36 am
Afaik the main reason why we don't have dual wield is engine limitations that can't (or only with a lot of trouble) be overcome even with WSE. But even if we could pull it off, I doubt there would be a consensus in the dev team to add it in. The historical evidence is thin. Off-hand weapons only seemed to reach a certain popularity in a time period that doesn't really fit to cRPG. Even then it would only be the off-hand daggers. So no dual swords, dual axes, dual pikes for you, Dragonborn.
Title: Re: What's with the dual wield hate?
Post by: Dooz on February 29, 2012, 11:13:31 am
Bah, it was never meant for me anyway. Consider me the dual wielding devil's advocate.

Regarding shield skill and ironflesh, you being able to move yourself and move your shield independently would seem to cover whether or not you can move to absorb hits, since speed bonuses exist. So you can already move away from an incoming strike to minimize damage, both to yourself and to the shield without the need for inventing invisible actions. You can argue one way or the other with things like this till the cows come home, then argue some more with the cows. And if you were so inclined, you'd do the same for dual wielding, which is where personal preference comes in at the end of the day.

To sum up, I'm not convinced it totally isn't historically accurate, definitely no reason to think it's impossible within the realm of physics and human ingenuity (both real life and coding-wise), and we sure have a lot more history professors and time travelers in the community than I would have imagined.  :mrgreen:

Time to be a smart ass:

There are always reasons something happens or does not happen.

There is no way to doupt that 2h ,1h+shield and polearms had large popularity in the window of time crpg takes place. There IS however not much proof that dual wielding weapons in that same era gained a lot of popularity. Since these people back then fought wars to the death and did not play games, (although im not a time traveler) Im pretty sure they used those weapons that prooved to be the most effective ones and not these that would give the most fun to carry into battle. In conclusion Id say that dual wielding simply was not as effective as other weapons we already have in the game.

BUT: Looking at the 1h weapons equipment page or any other, I see tons of weapons that are not used other than for teh lulz. Simply because they are not as effective as other ones. "Its not historicly accurate" sounds like implying that people back then didnt "unlock" the ability yet to be able to think about puting one weapon in each hand.

That said: If dual wielding is simply not vastly effective, as plenty of other things in the game right now are not as well, just add it but balance it in a way that it is simply not vastly effective. I really dont see the point here to not implement it just because there are no big battles in history that show its existence. In real life i might paint the fletching of my arrows light red to be able to see them flying at greater distances better. In real life, if Id carry a bow in a castle, knowing there could be an enemy around the next corner, Id definitly hold the arrow already nocked, saving me much time that could be the difference between life and death, instead of starting to pull it out of my quiver just when someone jumps around the corner 2m infront of me. Its not like god comes down from the heavens and sais "Mortal, you shall not do this, as it is not written down in the history books".

Personaly I dont care as Im not a melee. But why not give melees a new toy if its not gamebreaking ?

That's not what I meant. The dagger/sword fighting style fits in the late period of this mod.

The true problem is implementing dual wielding. And making it different than a shield, but not preventing blocks either.

Post by: Gravoth_iii on February 29, 2012, 09:07:33 pm
Id say this would be pretty cool, with or without blocking, you could use 1 weapon for blunt/pierce damage or for knockdown, and one for longer reach. Who cares about realism or that it isnt practical, it'd still be a cool addition imo, adds some more variation.

Sorry for being a prick, in general. Character flaw. And thanks to those who responded reasonably.

But what exactly are you referring to when you say I'm discussing things that only exist in my head (putting aside the possibility that everything only exists in one's head)? What am I making up? I'm not the one pretending to know what went on centuries ago and denying all possibility of something that frankly doesn't seem impossible. I don't assert dual wielding was a popular style anywhere in my posts, and did provide a couple links that seem to suggest it at least existed.

Also, quoting another user's post and referring to it as if it's mine seems weird.  :P

They had the ability to use dual wielding, but it was not only fairly ineffective, was a sure sure way to get you killed. Their 2nd second so to speak was the shield, which they used in a number of offensive and defensive way.

That's still missing the point of it being possible, and allowing for the option of using an ineffective method if you should so choose.

Also, when was the last time black guys were on a medieval battlefield in shining armor? If we're only sticking to what happened on battlefields, and even then only what was most prominent and not just possible, then we should get rid of the darker skin tones. But that'd be silly. Almost as silly as disallowing dual wielding.  :P

I'm not talking about what came first, just what existed.

Quote
Musashi created and perfected a two-sword kenjutsu technique called niten'ichi (二天一, "two heavens as one") or nitōichi (二刀一, "two swords as one") or "Ni-Ten Ichi Ryu" (A Kongen Buddhist Sutra refers to the two heavens as the two guardians of Buddha). In this technique, the swordsman uses both a large sword, and a "companion sword" at the same time, such as a katana with a wakizashi. Although he had mastership in this style of two swords, he most commonly used a katana in duels.

Going around in circles here, but point is it existed. Unlike black guys on a european battlefield. So if guys from Africa at the time could conceivably go to Europe and loot their shit and fight alongside presumably racist white knights, a samurai master could teach his dual sword techniques to those same knights.

In my opinion Musashi's argueing for dual wield had mainly philosophical reasons. If you read his work then it becomes obvious that one of his main ideas was not to develop a preference. On the battlefield a commander shouldn't generally prefer one troop type but equally employ infantry, ranged and cavalry, only depending on the circumstances. Becoming to attached to a single troop type or tactic makes one predictable and vulnerable - it becomes a weakness.

A similar idea seems to be behind using two weapons with both arms. That way the weaker arm is constantly trained to wield a weapon on his own and the warrior can still fight well even if his strong arm is incapacitated. Again, the main goal is to overcome the weakness of having a preference, a weak and a strong arm.

It seems to me that this is a very elite and idealistic thing, probably unrealistic for the common warrior. He is better off taking every opponent seriously and expecting him to be on an equal level. Dual wield would probalby weaken the warriors blows and parries which is especially bad against an armored foe. I just don't see a place for it on the medieval European battlefield.
