What is this?:
This is a little python script made by my genius brother to help me balance weapons in my mods faster.
What exactly does it do?:
You just have to point it to the weapon's .hml file file and it will automatically examine the weapon's stats and do a bunch of calculations for you, then pump out some more useful stats so you can see how the weapon is performing.
What sort of stats?:
Here's an example of what it puts out when targeted at a .hml file with only the Vanilla M-16 in it:
Reading xml file: VanillaWeapon-M-16Rifle.xml
cooldownTicks: 40.0
DamageAmountBase: 7.0
basePrice: 325.0
warmupTicks: 108.0
range: 32.0
accuracyTouch: 0.96
accuracyShort: 0.87
accuracyMedium: 0.77
accuracyLong: 0.64
burstShotCount: 3.0
ticksbetweenburstshots:7.0
Ticks per shot: 56.333333333333336
Shots per second: 1.0650887573964496
Damage per second:7.455621301775147
Power Rating before accuracy: 238.5798816568047
Power Rating: 229.0366863905325
Suggested Silver Value: 458.073372781065
So as you can see, it first of all shows all the basic stats that are visible, cooldown, damage, price, warmup, range, accuracy, and burst fire information.
Then it does some calculations and shows you some extra stuff.
Ticks per shot is found by multiplying the burst shot count by the ticks between burst shots, then adding that figure to the warmup and cooldown, then dividing by the burst shot count. Now you don't have to do all that though, it does it for you.
Shots per second is found by taking 60 and dividing it by the ticks per shot.
Damage per second is found by taking the shots per second and multiplying it by the damage amount base.
Power Rating before accuracy basically just takes the damage per second and multiplies it by the range.
Power rating takes the power rating before accuracy and multiplies it by the largest accuracy figure.
Suggested silver value just multiplies the power rating by 2. Might not be ideal for everybody, but it's about where I want things for my mod. You can always do whatever you want with all this infromation, of course.
How does this balance play out?:
Well here's all the non-incendiary/explosive vanilla Alpha 5 weapon's power ratings:
Thrown Stones: 25
Pila: 74
Short Bow: 78
Great Bow: 109
Pistol: 124
Shotgun: 124
Uzi: 145
Lee-Enfield: 172
Charge Lance: 190
M-16: 229
M24: 240
LMG-15: 264
R4: 312
Minigun: 369
Heavy Charge Blaster: 380
The Minigun and Heavy Charge Blaster both have an extra stat "forced miss radius" that isn't taken into account by the formula because I don't know how it works, exactly.
For the sake of this list I've taken the accuracy value, divided it by the forced miss radius, then multiplied it by the power rating before accuracy value.
Result:
Minigun:
Power Rating without forced miss: 887 (I think this is inaccurate stat in this case)
Power Rating before accuracy: 1123
Accuracy: .79
Forced miss radius: 2.4
Accuracy divided by forced miss: 0.3291666666666667
Power rating with forced miss radius: 369.6541666666667
Heavy Charge Blaster:
Power Rating without forced miss: 1103 (I think this is an inaccurate stat in this case)
Power Rating before accuracy: 1186
Accuracy: .93
Forced miss radius: 2.9
Accuracy divided by forced miss: 0.3206896551724138
Power rating with forced miss radius: 380.3379310344828
Overall I think that's a pretty accurate assessment, but it does change from situation to situation. For example the pistol and shotgun have the same rating, but they're very different weapons. The Shotgun has about half again more DPS but the pistol has about half again more range.
In close quarters combat the shotgun is a lot better, but in an open skirmish I personally actually prefer the pistol because the range is so much better.
Likewise the M16 and M24 have a similar power rating. In some situations (such as attacking siege bases) the M24 is a lot better, but in base defense I generally prefer the M16 because it has more then adequate range for that situation and has slightly better DPS.
Also, the accuracy stats are a little funny. Right now the formula only uses the highest accuracy stat. I chose that because then it assumes that the player is using the weapon to it's greatest potential, carefully choosing the range that will best complement it.
If I instead made the formula average together all the accuracy values together then you get some funny results. For example a shotgun has low enough range that it basically only uses the touch and short range stats, and the medium and long range stats will basically just confuse the formula and make the weapon seem worse then it actually is.
In the end, if you don't like the accuracy system I've used, or even the entire power rating system the script will still put out stats like DPS and power rating before accuracy, so it'll still speed up whatever formula modifications you want to use.
So take it with a grain of salt, but at the very least I think it gives people a good starting point for their weapon's balance. At the most I'm planning on using this formula exclusively for my new mod.
Bullet speed isn't taken into account because it has such a small effect on combat that it's not worth taking into account in my opinion. (And yes, it does have an effect on combat. If you want to know what it is ask and I'll post the long explanation, and show that it does make a difference but it's so small that it doesn't matter 99% of the time.)
How do I get this?:
First of all you'll need python. It's a free download and can be found here. (https://www.python.org/downloads/) I'm using 3.4, you should probably try to get the same version, unless you know a lot about python and can fix it as you go along.
Second of all you'll need to download my brother's script.
You should hopefully be able to download it from File Dropper here. (http://www.filedropper.com/rwb)
If that download doesn't seem to be working then either post here or send me a PM or something so I know it's not functioning, I've not used a free upload/download site before. On that note, I'm very open to suggestions of which free site to use and could upload it again.
Alternatively you could send me a private message saying you want it with your e-mail address and I can send it to you in an attachment.
How do I use it?:
Okay, put the rwb.py file somewhere that you'll remember.
I've put it in my Python34 folder, which I installed right into C:. So if I want to find it, it's in:
c:\python34\
Go into your mod and hold down shift then rightclick on the folder that has all your weapon .hml files in it. In the popdown menu there should be the option: "Open Command Window Here". Press that.
It should open command prompt, which looks a lot like MS/DOS if you're old enough to remember what that is.
It'll show a text line that has your mod file directory in it.
Mine looks like this:
C:\RimWorldAlpha5Win\RimWorld492Win\Mods\ProjectArmoury211\Defs\ThingDefs>
This is because I'm looking at the ThingDefs folder in the Project Armoury mod.
Now you should type in:
python (rwb.py with it's directory here) (.hml filename you want it to check here)
On my computer it looks like this:
python c:\python34\rwb.py PA_MedievalWeapon-Crossbow.hml
If I hit enter, then it'll pop out all the Crossbow's stats, like this:
C:\RimWorldAlpha5Win\RimWorld492Win\Mods\ProjectArmory211\Defs\ThingDefs>python
c:\python34\rwb.py PA_MedievalWeapon-Crossbow.xml

Hopefully that makes sense to you. :P
Extra important bugfixing stuff:
Python is case sensitive. If you type "RWB.py" instead of "rwb.py" it won't work.
This especially applies for stuff inside of .hml files. One of the stats it's looking at is the <DamageAmountBase> </DamageAmountBase> figure. For whatever reason about half of Tynan's weapons have the "D" capitalized, and the rest have it in lower case. The script doesn't recognize the lower case ones, so you have to go through your files and make sure that "D" is capitalized it to make it work.
.hml files can't have the same stat in it twice. The script will collect data from one and ignore the other. (and not tell you that it did so) So you need to have all the weapons in their own .hml files, not all bundled together. If you look in the Core mod's weapons they're all bundled together. It won't work on them unless you separate them all into their own files. If you look at Project Armoury's weapons you'll notice that almost all of them are in their own files, which will work.
This also applies in some cases where the stat shows up twice. In the upper "BaseGun" section of a weapon's .hml file is a "CooldownTicks" stat, usually it's at 40. Some guns have a replacement "CooldownTicks" stat which will overwrite the upper one in the game. This python script will only read the top one though, so you'll want to replace the top one's stat with the bottom one's stat. (which is totally fine if there's only 1 gun in the file. If there's more than 1 gun in the file it'll change the stats on all the guns, so split them apart first)
Also, sometimes modded guns have special duplicate stats. For example mrofa's boomerang uses 2 projectiles, each with their own stats which will confuse the python script. For these guns I suggest either doing the formula by hand, or copying the weapon file then removing the second bullet on the copy and running that one through the script to see how the weapon works.
It doesn't take into account fire or explosive stuff, so just use it on "normal" weapons for now. Grenades, mortars, and Molotov Cocktails won't work.
If you run into other problems, please say so and post any errors or anything that comes up.

Veeeeeeeeeeeeeeeerrry nice :D It looks like it still needs a little refining to me, but otherwise I will definitely use this if the need arises. Using the same version can be very important, 3.2 and 3.4 handle lists very differently for example so I would be wary there.

So, could you explain to me how the ForcedMissRadius works? Then maybe I could come up with a good way to take it into account and coerce my brother into coding it so this thing gets a little better. :)

If forcedMissRadius > 0, the game chooses a random miss distance d where 0 < d < forcedMissRadius. It then chooses a random angle. It then determines the square at that distance and angle away from the target center square. If it is in the same square as the target center square, all proceeds as normal. If not, the shot is fired at that square instead.
It's used for making weapons that spray shots over a wide area.

Okay, cool. I'll probably mull that one over for a few days and do a bit of experimentation with it.
Thanks.
This is a pretty great tool, but it should really take time to kill (TTK) into consideration.
Sure, guns like the Lee Enfield have good accuracy, but are totally outclassed by the fire rate of a pistol mostly because of the low damage/high warmup.

The DPS stats show that the LE has 4.86 and the pistol has 5.5. So yes, the pistol will kill a target faster if it hits with every bullet.
If we take the touch accuracy into account (by manually multiplying the accuracy and the DPS with a calculator) we get:
LE: 4.67
Pistol: 5.05
So, yes, the pistol still has a higher "true" DPS at close range.
So we could fairly easily add a new stat where DPS is combined with accuracy but doesn't take range into account. I don't really know what to call it. (Maybe "True DPS" or "stopping power" or something) Would that be good enough for you?
Calculating TTK is a different story though. It'd be easy enough to make the system automatically figure how how many shots a gun needs to remove 100 hitpoints then compare that to the bullets per second to see how many seconds it takes to put a standard unarmoured human down, but that system will go obsolete very soon because in the
upcoming now released Alpha 6 the character health system
is changing has changed a lot.
Why not just output separate DPS for each range?
Quote from: Tynan on August 13, 2014, 12:27:03 PM

Could do that too. ;D Good idea.
So I'd probably change "DPS" to "Base DPS" then add touch/short/medium/long DPS stats.
I'll see if I can get together with my brother tonight so we can get it updated.
Any other suggestions in the mean time?
Here's an example of what the tool can do.
I measured the power rating of all the weapons in the upcoming Project Armoury Release. (which we want to balance, because it's bad in some areas... look at the strongest vanilla weapon and then look even further down if you don't believe me) Overall, it took me less than an hour and a half to make this list. Can you imagine how long it would have taken me to run through the formula by hand on each of these? And can you imagine how many errors I would have made as my mind turned to mush, throwing the balance off?

That's over 150 weapons, in case you were wondering. ;D And that time included bug fixing. (about a quarter of the weapons needed the "d" capitalized in their .hml files, and there was a few other things)
Bog: I suggest you do some math to have the tool reduce its power estimate for overkill. E.g. a weapon that does 1000 damage isn't 10x better than a 100-damage weapon because once a body part is destroyed the rest of the damage is wasted. You can bias the results in favor of smaller damage amounts per shot to capture this effect.

Thanks for the input. I didn't think of that. In fact I've actually been contemplating the opposite effect, ie:
If a gun does too little damage (Thrown Stones, Uzi) it won't do enough damage to any given body part before "going on" and damaging the next body part, so a target might end up with a lot of very minor survivable wounds instead of a few strong ones. On the other hand a gun with high damage (M24) might take out any body part it touches with the first shot it fires, giving it a much higher chance to kill or severely cripple someone right off the bat. (and a shot that instantly permanently cripples a colonist is a lot worse for players then a bunch of weak shots that can be potentially recovered from, so in their eyes it's more dangerous, and so also "more powerful".)
So I was previously thinking about making the formula value higher damage weapons more. :P
I think I might have to come up with a way to do both at the same time, valuing damage to a point and then not counting it with the same weight because of the overkill. Of course I'll probably have to set it up for a regular humanpawn vs. humanpawn battle as that'll be the most common battle and the upper damage threshold is probably a lot higher on a centipede, which throws things off again. (assuming centipede's body parts have more health than human. I haven't specifically checked.)
Hopefully sometime this week I'll have the time to systematically figure out where the system evens out. Is a pistol that only has 1 damage but shoots 10x as fast better? Or would it be better to shoot 1/5th as fast but deal out 50 damage a shot? Or is it best as-is?
I'll probably answer those questions through a lot of trial and error by spawning colonists and making them shoot each other to death. ::)
.....
By the way, how does the "death threshold " work? Do people just die when a vital part (heart, brain, blood loss, etc.) reach 0? Or can they still be killed though damage volume if it doesn't finish off a vital part? That'd make a huge difference to my thoughts.
Also, how is blood loss measured? Does any damage contribute to it making it like the old health system?Never mind, found a good thread on it. ;D

Assuming that losing a limb is something that you want to avoid, then pistol that deals 1 damage but shoots 10x as fast is less deadly than one with higher damage but normal shooting rate, because damage is then equally distributed among all body parts.
For example if someone's body consists only of 3 parts with 50 health each (all with 33.(3)% coverage), then one 50hp bullet = 100% chance to lose a limb, while 50 1hp bullets would usually lead to ~16 damage per body part.

For example if someone's body consists only of 3 parts with 50 health each (all with 33.(3)% coverage). Then one 50hp bullet = 100% chance to lose a limb, while 50 1hp bullets would usually lead to ~16 damage per body part.
Yup, that was my point when I made the post. I'm just wondering where the "sweet spot" is, because if you make the weapon do too much damage it gets waste, as Tynan said.
So if I make a whole bunch of weapons with the same DPS, but they have different bullet damage and rate of fire the current RWB system will think that they're equal in usefulness. But in reality there'll be some which don't perform well because the bullet damage is too low, not letting them easily destroy body parts because the damage gets shared between them.
There will also be those which don't preform well because bullet damage is too high, and when they destroy a body part there's still extra damage which doesn't get the change to affect the target. In these cases the gun doing less damage but getting a higher rate of fire to maintain it's DPS would actually make it better.
I've been doing some preliminary thinking in this area, so far I've made a list of the different body parts broken down into "wound severity" and mapped out where the damage reaches thresholds where it'll instantly destroy body parts.
In the end formula hopefully we'll be able to get it so that the system will value a bullet in accordance to the variety and severity of wounds that it can give, then devalue it in accordance to how much waste it has from overshooting the different wound thresholds.
Wound types in accordance to the kinds and number of body parts with their HP stats:
Leathal hits: (x6)
Torso 40 HP
Head 30 HP
Skull 30 HP
Neck 30 HP
Heart 20 HP
Brain 10 HP
Dual Lethal hits: (x4)
Lung 20 HP (x2)
Kidney 20 HP (x2)
Paralysis: (x11)
Spine 35 HP
Leg 30 HP (x2)
Pelvis 25 HP (x2)
Tibia 25 HP (x2)
Femur 25 HP (x2)
Foot 20 HP (x2)
Medium Injury: (x16)
Arm 30 HP (x2)
Clavicle 25 HP (x2)
Humerus 25 HP (x2)
Radius 20 HP (x2)

Jaw 20 HP
Eyes 10 HP (x2)
Ears 10 HP (x2)
Small injury: (x34)
Sternum 25 HP
Rib 15 HP (x12)
Nose 10 HP
Fingers 7 HP (x10)
Toes 7 HP (x10)
Minor injury:
(nothing)
(Note: Stomach, Jaws, Eyes and Ears have been classified as "medium injuries", but I haven't checked to see exactly how badly they affect characters in comparison to losing an arm.)

Ideally the system should value weapons that have a higher ability to kill or maim targets, then start to care a lot less about damage per bullet after it reaches a certain threshold because the extra damage is all wasted.
So my gut feeling just looking at the data without doing any real math is that against un-armoured targets 30 damage might be the most "efficient" bullet type. It can instantly destroy the vast majority of most body parts, and also looks like it has the best "damage to lethal hit" ratio.
Of course that's only covering unarmoured humans, it doesn't take power armour or mechanoids into account.
For example, right now against humans I think the bullet damage probably hard-caps at 62. That's when a gun should be able to kill a target with a single torso shot even if it's wearing power armour. Any damage more than that shouldn't help the weapon at all and so shouldn't add to it's power rating by much at all. Of course a 1000 damage super-gun would still be useful for destroying cover in a single shot, so there's nothing in the way for a second shot. Oh, and blowing up mortars and stuff. ::) I also haven't yet checked centipede's body parts and their HP yet on this front. :P
If I'm writing too much and not making sense it's because I'm having an information overload. My mind is racing thinking about all of it. ;D
Anyways, still processing...
Edit: Had a good long chat with my brother about this. We're pretty optimistic that we can make it work, and do it in such a way that it can be fairly easily "calibrated" after it's been made if there're changes in the health system.
Well we did a bunch of work on the new version last night. It's not ready for release yet but it's looking pretty cool.
Here's a chart based on it's attack value calculations:
(http://i.imgur.com/rLQp47z.png?1)
So the bar on the bottom is the Damage after Armour stat. (which is basically BaseDamage with armour reduction applied)
The bar on the side is the "attack value" which in the new version is later multiplied by shots per second, accuracy and range to figure out the weapon's power rating.
As you can see, the weapons get a lot more attack value in Alpha 6 whenever they cross a threshold that allows them to destroy body parts, but crossing that threshold also starts causing "overkill decay" which lowers the passive attack value gain. At first the weapon gains 1 attack value for every 1 base damage it has, but after it passes the 40 damage mark it's finished eroding down to less than .1 attack value per damage it gains.
Here's the above stats in "list" format:
Damage Attack Value
1 1.0

Notice how at 7 damage the value jumped from 6 to 9? That's because a 7 damage weapon can shoot off a finger or toe in a single shot. A 6 damage gun needs 2 shots.
The damage thresholds for injury types are listed in my previous post.
The current bonus attack values are:
small_injury_value = .1
medium_injury_value = .3
paralysis_injury_value = .6
dual_lethal_injury_value = .5
lethal_injury_value = 3.0
These numbers are added to the attack value every time a gun reaches a threshold for that type of injury.
The current overkill values are:
small_injury_overkill = .0017
medium_injury_overkill = .0059
paralysis_injury_overkill = .0175
dual_lethal_injury_overkill = .0145
lethal_injury_overkill = .0873
These numbers are multiplied by the BaseDamage gained after reaching the threshold for their type of injury, then that number is subtracted from the attack value.
The injury values and overkill values can be really easily modified, so I can change them later to "calibrate" the formula. :)
I have two questions though,
First, how does the armour handle rounding? So if a 7 damage gun hits someone wearing power armour it has a 35% damage reduction. That comes out to 4.55 damage. Does the game handle that as 4 damage, 5 damage, or what?
Second of all, do all the body parts have the same chance of getting hit? Like if a guy gets shot with a bullet, is it equally likely to hit his left pinky as hitting his right big toe as hitting his brain as hitting his torso?
Thanks in advance.

Generally, 4.55 would be rounded up, 4.51 would be rounded up, 4.50000001 would be rounded up, but I'm guessing like most programs (and computers in general) that 4.5 is rounded down.
As for your second question, I have a really detailed article about how the damage model works. Not every part has the same chance to be hit, but rather is determined by a "coverage" percentage that determines what the chance there is to hit a certain group of body parts
http://rimworldwiki.com/wiki/Human
This is highly subjective to where the body part is located - for example, the brain has a 100% coverage rating, and the brain is in the skull (and the skull is inside the head). This means anything that hits the skull will also hit the brain (there is no account for glancing blows I guess), but the chance of having a bullet strike the head -> hit the skull is very low.

Thanks a lot. That'll help us get chart the attack value of weapons a lot more accurately.
Do you still have this?
