[VXA] Individual Strikes when Dual Wielding

Individual Strikes when Dual Wielding
Version: 1.0.1
Author: modern algebra
Date: 2 February 2013

Version History

• <Version 1.0.1> 2013.02.02 - Fixed a bug where use of item 1 by dual wielding characters would be replaced with an attack.
• <Version 1.0.0> 2012.09.22 - Original Release

Description

This script changes the dual wielding option so that, instead of the actor attacking only once with increased damage, the actor attacks twice, once with each weapon. Additionally, this script allows you to modify the damage formula when dual wielding, thus allowing you to, for instance, make the actor's proficiency with dual wielding dependent on the actor's dexterity or some other stat.

Features

• Individual Strikes when dual wielding
• An easy way to modify the damage formula when dual wielding for balance purposes
• Compatible with Weapon Damage Formulas

Instructions

Paste the script into its own slot in the Script Editor, above Main but below Materials.

If you wish, you can assign a modifying formula at line 38. What that will do is allow you to change the damage formula for a weapon when you are dual wielding, and it serves as a way to assign a penalty to dual wielding for balance purposes.

#  By modifying this constant, you are able to modify the damage formula when
# dual wielding. It must be a string, and the original damage formula will
# replace the %s. In other words, if the original damage formula is something
# like "a.atk * 4 - b.def * 2", and you assign the constant to the following:
#    MAISDW_DUAL_DAMAGE_MODIFIER = "(%s)*0.75"
# then the formula when dual wielding would be: "(a.atk * 4 - b.def * 2)*0.75"
MAISDW_DUAL_DAMAGE_MODIFIER = "(%s)"

If you're using Internet Explorer, then code boxes do not play nice. You might need to retrieve the script from Pastebin instead.

Known Compatibility Issues

I am not currently aware of any compatibility issues.

SiliconDragon reports that it appears to work well with Kread-EX's Custom Weapon Formulas, but that the expected damage is mildly reduced.

Author's Notes

I wrote this script basically to complement my Weapon Damage Formulas script since the default dual wielding scheme did not accomodate for a situation where the two weapons have different formulas.

Terms of Use

I adopt RMRK's default Terms of Use.

How would Yanfly's Weapon Attack Replace work with this? Would it use both attack skills as set on both weapons?

Well, I've never looked at that script before, but judging by its name, I assume it is essentially like my Weapon Damage Formula script? If so and if it is similarly designed, then yes. Why not try it out and get back to me if you discover it doesn't work?

All Yanfly's script seems to be doing is stopping yours from working correctly, though it's hard to tell using the default battle system. It just displays one attack, simply says "(name) attacks!"; but giving one weapon an attack that merely poisons without fail and an attack that merely blinds without fail(both with 1000% chance) has them both work.

That sounds fine? What should happen is that it should say:

"(name) attacks"
"x damage dealt"

And then "x damage dealt" should be replaced with the damage of the second weapon.

I assume that both animations are shown?

Both animations seem to be shown, the second one appears mirrored which I believe is normal

Yeah, then I think it's working as intended. Is there a problem with the way it executes?

Not as far as I can tell. I didn't test it too extensively, not every single possible combination, but I couldn't see anything wrong, just the "(name) attacks!" only appearing once.

Alright, then I think that's fine. It's only supposed to show "(name) attacks" once.

Will this script use the damage formulas of both weapons if they have custom formulas using this script: http://grimoirecastle.wordpress.com/2011/12/13/custom-weapon-formulas/ by Kread-Ex?

Hmm, my guess is yes. Why not try it out and see?

Just tried it out and it seems to be working, except it subtracts one from the damage of each weapon, and the off hand weapon seems to never miss.  I need to test the off hand weapon more, but in three battles of ten to twenty rounds it never missed, though the main weapon did about half the time.

Well, the lessened damage might be because this script unequips the non-attacking weapon for each attack, in order that the stats of the non-attacking weapon don't affect the damage of the attacking one.

As for the off-hand weapon not missing, err, don't know? Nothing in this script should affect hit rate.

Thanks, unequipping a weapon shouldn't have changed the damage because I used an set damage of 10 for main weapon, and 5 for off-hand weapon, no stats or anything else effecting it so I could see if I was getting expected values.

And the damage formula for the skills you are using is purely just actor.atk? It doesn't subtract from the opponent's defence, it has no variance, etc.?

Anyway, are you asking me to do something? If so, then please clarify, and also create a new project with both scripts in it and recreate the error, then upload it to me so I can see what's going on.

can you make it where you can select the hand you attack with?

Not with this script, no. You always attack with both.

It would be possible to add that option, but I don't intend to write that.

@modern algebra, no there is no request I just others trying use both scripts would like to know how they worked together, and to test them I just placed 10 in the main hand formula and 5 in the off hand weapon formula so I knew exactly what the damage was supposed to be, in actual game the formulas will be a bit more complex.

Alright, thank you for doing that. It is very helpful for those other users and I will add that information to the initial post.

There seems to be a bug in your script.
When using a healing item with dual wielding character, such as a potion, instead of healing it damages.

Thank you for reporting that bug! I've updated the script to v. 1.0.1 to fix it.
