How do values interact with attributes?

If you're here, you probably already realise TF2 (item-based) attributes just blows your head off, and you hope this guide resolves that. I think you already get the gist.

Introduction

Is ("damage bonus" 0.20) = "+20% damage bonus"? Is ("fire rate penalty" -9.0) = "-90% fire rate penalty"? If you answered YES to either, you may need to reunderstand the nuances of attribute-values!

All attributes interpret given values according to what they expect the value type to be, which is unknown when without the data of the attributes. This list of item attributes hosted on the TF2-wiki summarises the relevant attribute data from "scripts/items_games.txt". Click on a table header, like "Name", to re-sort the table's order.

Now, a disclaimer to this guide:

1. This is not a comprehensive list of every single valid value-type.r
   
2. Attributes can function identically even if their names or game-description is different, such as the "damage bonus" and "damage penalty" pair. Item attributes obtain their code-functionality from their "attribute class", the rest are distinct settings.

I hope there won't be more confusions, but if you do, give this guide a comment.

additive

If you put 1, the value will be 1. It's usually used for attributes that use 1 or 0 as "True" or "False".

percentage

As the name implies, it uses percentage, so 0.01 goes to 1% in-game.

If you give a bot's Bat "damage penalty" 1.5, it would appear as "-+50% damage penalty" in-game. If the Bat instead is given "damage bonus" 0.5, it would appear as "-50% damage bonus" in-game.

inverted_percentage

This attribute works like percentage but works the opposite. I'll use "fire rate bonus" and "fire rate penalty" for examples, even though they work the same and the only difference is the text.

Expect 0.4 in "fire rate bonus" to be "-60% fire rate bonus" (fires 60% faster) and 1.6 in "fire rate penalty" to be "+60% fire rate penalty" (fires 60% slower).

additive_percentage

A strange attribute value type, but also among the least used ones. There are one of two ways an attribute interprets a given value:

• 1 equals to 1%
  
  • Example: "charge meter on hit" 25
    
• 1 equals to 100%
  
  • Example: "ammo regen" 0.75
    

There is no pattern for which method will an attribute use! No need to trouble yourself with a value type that's used across 11 uncommonly-seen attributes, I've already done it for you.

The following table that condenses these data:

• Name of all attributes that use this class.
  
• Their method of value interpretation.

Attribute Name	100 is 100%	1 is 100%
add uber charge on hit	✓	✘
tmp dmgbuff on hit	N/A	N/A
slow enemy on hit	✘	✓
ammo regen	✘	✓
electrical airblast DISPLAY ONLY	N/A	N/A

override projectile type attribute

Meant for override projectile type;This attribute changes what is shot out of a weapon, and is seen abused by many mission makers.

Below here you will find a list of IDs for override projectile type I made along with some miscellaneous information in it:

PROJECTILE_INVALID              = 0 // (self-explanatory)
PROJECTILE_BULLET               = 1  // Bullet (does not create a bullet trace on weapons that don't normally shoot bullets, to show bullet traces use "sniper fires tracer" or "sniper fires tracer HIDDEN" attribute)
PROJECTILE_ROCKET               = 2  // Rocket
PROJECTILE_PIPE                 = 3  //  Pipebomb (only works well with weapons that shoot projectiles except Rocket Launchers)
PROJECTILE_PIPE_REMOTE          = 4  //  Stickybomb Launcher's stickies  (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_SYRINGE              = 5  // Syringe
PROJECTILE_FLARE                = 6  //  Flare, flare type can be changed with set_weapon_mode (does not inflict afterburn with weapons that can't set enemies on fire in vanilla PvP by any means)
PROJECTILE_JAR                  = 7 // Jarate (only works with Jarate weapons)
PROJECTILE_ARROW                = 8  //  Huntsman arrow (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_FLAME_ROCKET         = 9  //  Unused projectile meant to fire a flame rocket, no longer works (has an unused implemented function, CTFWeaponBaseGun::FireFlameRocket(CTFPlayer*) )
PROJECTILE_JAR_MILK             = 10  //  Mad Milk Jar (only works with Mad Milk weapons)
PROJECTILE_HEALING_BOLT         = 11  //  Crusader's Crossbow arrow (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_ENERGY_BALL          = 12  //  Cow Mangler Particle (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_ENERGY_RING          = 13  //  Bison / Pomson Laser
PROJECTILE_PIPE_REMOTE_PRACTICE = 14  //  Stickybomb (Sticky Jumper) [only works well with weapons that shoot angled projectiles except Flares and Syringes]
PROJECTILE_CLEAVER              = 15  //  Flying Guillotine Cleaver (only works with The Flying Guillotine)
PROJECTILE_STICKY_BALL          = 16  // unused projectile, can't be summoned using this attribute
PROJECTILE_CANNONBALL           = 17  // Loose Cannon cannonballs (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_BUILDING_REPAIR_BOLT = 18  //  Rescue Ranger bolts (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_FESTIVE_ARROW        = 19  //  Festive Huntsman arrows (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_THROWABLE            = 20  //  Summons the throwable of the current weapon being held out, nothing happens if the weapon is not a throwable item such as Gas Passer
PROJECTILE_SPELLFIREBALL        = 21  //  sf2013 fireball spell, cannot be summoned using this attribute
PROJECTILE_FESTIVE_URINE        = 22  //  festive jarate (only works with Jarate weapons)
PROJECTILE_FESTIVE_HEALING_BOLT = 23  // festive crusader's crossbow arrow  (only works well with weapons that shoot angled projectiles except Flares and Syringes)
PROJECTILE_BREADMONSTER_JARATE  = 24  // self-aware beauty mark (only works with Jarate weapons)
 PROJECTILE_BREADMONSTER_MADMILK = 25  // mutated milk (only works with Mad Milk weapons)
PROJECTILE_GRAPPLINGHOOK        = 26  // grappling hook (hooks take a long time cleaned up / removed; they can take up to 30 seconds to be removed)
PROJECTILE_SENTRY_ROCKET        = 27  //  cannot be summoned with this attribute
PROJECTILE_BREAD_MONSTER        = 28  //  cannot be summoned with this attribute (the bread monster that appears on a player's head?)
PROJECTILE_JAR_GAS            = 29  // Gas Passer projectile (only works with the Gas Passer weapon)

reasons on why some projectiles don't work:

"Projectiles that only works well on weapons that shoot angled projectiles except Flares and Syringes" : these ones when given to the wrong weapon will slightly go upwards before dropping straight down to the floor

CM5K is special, it will stay in place and eat fps until an enemy entity runs into them instead

Don't give stickies to a bot that isn't the Demoman, they won't detonate no matter literally anything you do, including setting a sticky max cap for them

"Cannot be summoned / works only with [weapon]" : The projectiles won't spawn when the weapon is fired and weapon firing sounds will not play

IF A PROJECTILE ID USED DOESN'T EXIST IN THIS LIST IT CRASHES TF2

AND DON'T USE "override projectile type" WITH A LOOSE CANNON THAT DOES NOT HAVE "grenade launcher mortar mode" on 0, IF YOU DO THEN THE GAME CRASHES

Note that if you changed projectiles of a weapon, it's base damage will remain unchanged. Because of that you'll need to buff a weapon's damage if you don't want a rocket to deal 18 damage on a Bison.

Thanks to Benoist for reversing TF2 code, and Jakapoa for showing me Sigsegv's outdated list of projectile IDs he reversed years ago

mc (lol), Subsimple and Remilia for helping me test some of the projectiles out

exwum for the good looking and unique screenshots and some gyazo gifs

Small trivia: Righteous Bison, Cow Mangler 5000 and Pomson 6000 supports using both regular projectiles and angled projectiles.

Image examples
Left - A regular weapon using an angled projectile.
Right - An angled projectile weapon using an angled projectile.













Left - Bison's lasers being fired faster on an angled projectile weapon.
Right - Pomson's lasers being fired faster on an angled projectile weapon.






Upper Left - Righteous Bison firing an angled projectile even though it's original projectile it shoots is not.
Right - Pomson 6000 firing an angled projectile even though it's original projectile it shoots is not.
Bottom Left - Cow Mangler 5000 firing an angled projectile even though it's original projectile does not seem like one.

set_weapon_mode attribute class

Attributes that use this is extraordinary.

Since cool guy (Sigsegv) already has a documentation for this, I'll copy everything from it lol

"set_weapon_mode" attribute documentation

accurate as of TF2 version ~20160327

reverse engineering by sigsegv



General Notes

=============

There are many attributes in the game that map to attribute class "set_weapon_mode", with many different names:

- "fists have radial buff"

- "set cloak is feign death"

- "mod bat launches balls"

- "sniper no headshots"

- "set cloak is movement based"

- "revolver use hit locations"

- "mod shovel damage boost"

- "lunchbox adds maxhealth bonus"

- "lunchbox adds minicrits"

- "mod shovel speed boost"

- "mod bat launches ornaments"

- "set icicle knife mode"

- "mod flaregun fires pellets with knockback"

They all do the exact same thing though. All that really changes is the descriptions.


If you happen to want the features from more than one set_weapon_mode value on the same item at once: sorry, that's not possible.



Knives (tf_weapon_knife)

========================

Knife Mode 0

Big Earner Mode 0

Your Eternal Reward Mode 1

Conniver's Kunai Mode 1

Spy-cicle Mode 3


Mode 1:

- Suppresses automatic voice response MP_CONCEPT_KILLED_PLAYER after a kill

- When the weapon is active, sentries are unable to target you if you're in the process of disguising (i.e. not fully disguised)

- Enables some ancient code related to YER's auto-disguise mechanic, likely from before "set_disguise_on_backstab" was invented

  (apparently the knife weapon itself would basically just spam the disguise button every frame)


Mode 2:

- Doesn't do anything in the current version of TF2


Mode 3: "set icicle knife mode"

- Enables the HUD recharge bar for the knife


Notes:

- It appears that most or all knife features were originally done by "set_weapon_mode" but were later separated into their own attributes

- Things which you might expect to be controlled by "set_weapon_mode" which are actually controlled by other attributes:

  - YER's disguise-on-backstab and cannot-disguise-normally mechanics

  - Kunai's health-on-backstab mechanic

  - The "silent killer" mechanic

  - All of the Spy-cicle's special features, aside from the HUD recharge bar itself

Eviction Notice Mode 0

Holiday Punch Mode 0

GRU Mode 2


Mode 1: "fists have radial buff"

- This is a relic of a weapon concept that never made it into the game

- Disallows normal taunts

- Killing an enemy with the weapon forces its user to taunt

- Taunting results in a 1.0 second delay, followed by a radius effect on teammates within 1024 HU:

  - Gives 50 health

  - Applies a 0.5 second temporary +10% crit chance buff

  - (TAUNTATK_HEAVY_RADIAL_BUFF)


Mode 2:

- Doesn't do anything in the current version of TF2

===============================

Sandvich Mode 0

Festive Sandvich Mode 4


Mode 1: "lunchbox adds maxhealth bonus"

- Reduces the healing per bite from 75 to 25

- Adds attribute "hidden maxhealth non buffed" 50, for 30 seconds

- Reduces recharge time to 10 seconds (instead of 30 seconds)

- Alt-fire drops item_healthkit_small instead of item_healthkit_medium

- Makes the dropped healthkit use the candy bar model


Mode 2: "lunchbox adds minicrits"

- Applies no healing when used

- Adds condition TF_COND_ENERGY_BUFF for 16 seconds

- Adds condition TF_COND_COND_CANNOT_SWITCH_FROM_MELEE for 16 seconds

- Makes the dropped healthkit use the steak model


Mode 3:

- Makes the dropped healthkit use the robo-sandvich model


Mode 4:

- Makes the dropped healthkit use the festive sandvich model


Mode 5:

- Appears to be an unfinished "ammo sandvich" mechanic

- Each bite restores 25% of your max primary ammo (100% total)

- It still restores 75hp per bite as well (same as regular sandvich)

- Eating it at 100% health doesn't reset the effect bar but does refill your ammo

=================================

Bonk Mode 0

Crit-a-Cola Mode 2


Mode 1:

- Doesn't do anything in the current version of TF2


Mode 2:

Invis Watch Mode 0

Dead Ringer Mode 1

Cloak and Dagger Mode 2


Mode 1: "set cloak is feign death"

Disciplinary Action Mode 0

Equalizer Mode 1

Escape Plan Mode 2


Mode 1: "mod shovel damage boost"

- Uses pickaxe kill icon (TF_DMG_CUSTOM_PICKAXE)

- Enables the health-based damage boost mechanic


Mode 2: "mod shovel speed boost"

- Uses pickaxe kill icon (TF_DMG_CUSTOM_PICKAXE)

- Enables the health-based speed boost mechanic


Notes:

- The Half-Zatoichi is not a shovel



Mediguns (tf_weapon_medigun)

============================

Medi Gun Mode 0

Kritzkrieg Mode 1

Quick-Fix Mode 2

- Enables passive resistance on heal target

- Enables resistance cycling

- Enables Vaccinator-related TFBot AI logic for ubering and cycling resistances

- Changes the heal sound

- Enables "chunked" ubers of less than 100%


Notes:

- The "set_charge_type" attribute is mostly independent of "set_weapon_mode", so weird combinations may be possible

  - Example: a medigun that has QF-like movement abilities yet gives a kritzkrieg-like ubercharge effect

- However, Vaccinator needs "set_weapon_mode" 3 for it to know that it has 3 possible charge conditions

set_weapon_mode attribute class (continued)

Flamethrowers (tf_weapon_flamethrower)

======================================

Flame Thrower Mode 0

Backburner Mode 0

Mode 3:

- Changes flame particle effect to "flamethrower_rainbow"/"flamethrower_rainbow_FP"

- Changes world model to the bubble wand while taunting

- Changes the the flamethrower sound effect


Notes:

- Mode 2 was clearly intended for the "MVM Giant Flamethrower" item

  - Would have had scaled-up flame particles to make it look less wimpy

  - Presumably it would have had its actual flame reach extended as well

  - As far as I know, this item never actually made it into items_game.txt

  - There is still a reference to this item in the TFBot code to this day:

    pyro bots who have it will believe their effective range is 875 HU instead of 250 HU

Mode 1: "mod bat launches balls"/"mod bat launches ornaments"

- Allows creation of the ball projectile


Notes:

- Regular bats (tf_weapon_bat) are unable to create ball projectiles, so don't waste your time trying that

Bows (tf_weapon_compound_bow and tf_weapon_crossbow)

====================================================

Huntsman Mode 0

Crusader's Crossbow Mode 1


Mode 1: "sniper no headshots"

- Doesn't do anything in the current version of TF2

- In old versions of TF2, this was responsible for disallowing headshots with the crossbow

  (nowadays, it's hard-coded into the game based on the projectile type)

Most weapons uses "lunchbox adds minicrits" for set_weapon_mode due to it being hidden and neutral.

Special Attributes worth mentioning

Cosmectic's paint colour attributes

• set item tint RGB and set item tint RGB 2

This attribute is for painting cosmetics and some weapons. This attribute uses RGB integer values. You can use this attribute to paint stuff with your own color/colour or RGB integer values from items_game.txt.

To get your own paint RGB integer value, first go here[www.w3schools.com] to look at the hexadecimal values of colors/colours you want (they start with # and can only have 6 characters).

Then copy it and go to this site[www.webpagefx.com] to convert the hex value into regular RGB values.

Afterwards, remember the RGB values or leave the tab untouched then go to this site[www.shodor.org] and find out what's the RGB integer value of the color/colour you wanted.

Format of the RGB values : 107 (RED) , 200 (GREEN) , 92 (BLUE)

If you wanted to convert RGB integer to hex, here you go[hewmc.blogspot.com]

"set item tint RGB 2" is used by team colored paint cans. If it is used, it will change the cosmetic's color for ONLY blue team.

Note that this attribute and the other aforementioned does not work on cosmetics that cannot be painted with paint cans in-game (or missing "paintable" tag in items_game.txt). That means they only work with items you can paint with paint cans.

Below here you can find links to each classes's lists of paintable items:

Medic bots and their ubercharge's related attributes

These two following attributes are related to Medic bots. They modify when will a Medic bot pop uber.

• bot medic uber health threshold
This attribute modifies the health the Medic bot or the patient it's healing must reach a certain health before it thinks it should pop uber. For example, this attribute is set to 100 and given to a Medic bot. When the Medic bot/Medic bot's patient reaches 100 HP, it will want to pop uber.

• bot medic uber deploy delay duration
This attribute modifies the time required to wait before Medic bots can deploy their ubercharge. When Medic bots think it's time to deploy their uber, value set by this attribute will be used to delay the time they want to uber. For example, this is set to 5 and given to a Medic bot, when the Medic bot reaches 50HP and wants to pop it's uber, it waits for 5 seconds before popping Uber.(Default: 0)

Miscellaneous

• is_passive_weapon
(The attribute name does has _ between them instead of spaces)

When given to a weapon, that weapon becomes a passive weapon (like the shields and gunboats and related stuff).

That means the weapon will always be active and can be used at all times regardless of which weapon is currently held.

For example, if I give the attribute to a Rocket Launcher, I can use the Rocket Launcher while using my shovel or my shotgun.

Note that you should not give this to two weapons at once to a single person or the game will crash.

There's a part on this video where this attribute gets shown what it is capable of doing.

(skip to 1:47 in this video)
https://youtu.be/Y9ZBtIxRBDc

• no self blast dmg
When set to 1, it does not nullify self blast damage but only greatly reduce it. When this is set to 2 it nullifies self blast damage and changes the rocket to the Rocket Jumper's Rocket.

Friendly Reminder

• Remember to check if the names/IDs of the attributes you used are spelt correctly.
  
• Check an attribute's attribute class to see if it's just a clone of another attribute.
  
• A few attribute classes start with "unimplemented". Don't use attributes that start with "unimplemented" in their attributes classes because that attribute IS unimplemented.

[Orinuse]

I'll revert my most recent edit and we'll leave it at that.

[D. B. Wooper]

Update: apparently I'm kind of an idiot. I was testing the complete wrong attribute, the one to increase spread as health decreases.

However, I tested the actual attribute and couldn't find any difference between inputs 0.1, 1, and 100. It seems like it's functionally a binary attribute, which is weird. On the flip side, there are some attributes that should be classed as additive percentage (like the Zatoichi's heal on kill) that aren't for some reason. I don't know if this one was originally an addperc, but it doesn't seem like one now.

Sorry for my mistake! I hope this clarifies things a bit.

[D. B. Wooper]

Yep, did some testing this evening and it looks like it's a 1-100 scale. I dropped myself to half health and shot at a wall from uniform distance with the attribute set to different values.
At 0.75: basically normal spread
At 3: noticeable spread
At 100: a lot of spread
At 999: absurd spread, like bullets hitting the ceiling above me

I also discovered that the Natascha needs set_weapon_mode 1 to spin up slower... but the Brass Beast doesn't need that. May have changed since sigsegv did his writeup, but it was interesting nonetheless.

If you'd like more testing done (not just on this), I'd be happy to do it!

@Gray Not pursuing this guide to be updated, but the marginal interest is there. If you're *sure* you're right, I'll take your word and add it to the guide, but its unlikely ill test it.

Not figuring out the exacts is fine, just see if you can confirm its on a 1-100 scale.

I don't know if you're still updating this, but I've done some research with mult_spread_scales_consecutive. It looks like it uses the 1-100 scale for its additive_percentage. I haven't calculated how much the spread changes, but it feels like the integer put in is the number of degrees the bullets deviate when at low health... but that's speculation.

Is there an attribute to where you can have the capper particle effects when it shoots apply to any hitscan weapons? I just want to go PEW PEW PEW

[Orinuse]
