Config Properties Megalist

Intro

Arma 3 documentation is scattered to the 4 winds, and this applies to config file properties as much as anything. This is an attempt to make a single master list of properties with links to [sources]. Yes, there are other partial lists but they have problems: obsolete information, and no links to their sources. So rather than rummage and re-order everyone else's lists, I'm going to add my own in the hopes that it serves as a comprehensive resource (by Arma standards!).

(This list was compiled in Fall of 2014, and should be up-to-date as of that point.~Olds.)

How Do Configs Work?

All configs get merged into one big config in memory when the game starts. Where duplicates exist, which config takes precedence depends on load order - the last config loaded "wins" by overwriting any previous value(s). Load order is determined by mod folder order, PBO name, but most importantly/properly by the "requiredAddons" section of the CfgPatches class.

How Many Config Files?

A corollary to the discussion above is that you can spread your configs across tons of little files or ball them up into one big one or anything in between. It is essentially a matter of clarity and ease of editing. There is no iron-clad rule that requires certain classes (e.g. CfgAmmo) to be located within certain filenames.

Weapons

For understandable reasons, weapons data is scattered across several different config classes. Defining a weapon properly requires working with all these classes.

CfgAmmo

Projectile-specific properties

airFriction

How much the projectile slows down as it travels through air. (Seems to be equivalent to Bird-Livingston's "ballistic K factor" * 0.0000001).[A, B]

caliber

[float>=0]. Penetrative power of a projectile based on speed. (A value of 1 is standardized as 15mm of RHA penetration at 1000m/s.) The formula for mm of penetration is: (projectile speed / 1000)x(caliber)x(bulletPenetrability of the target BISURF). So higher = more penetration. Restating the formula: caliber = (mm penetration @speedX)*1000 / (bulletPenetrability * speedX). <!>Adding caliber values to missile or rockets results is bugged and results in missiles flying through targets.[A]

muzzle velocity

Tricked you! Muzzle velocity for a projectile is defined in the CfgMagazines class and it's called "initSpeed".

CfgMagazines

Magazine properties plus some projectile-specific stuff that gets stored here instead of CfgAmmo.

initSpeed

tbd

CfgWeapons

Gun/launcher-specific properties.

dispersion

[float>=0]. Weapon's dispersion in radians (1 angular milliradian = 0.001 dispersion, 1 MOA = 0.000290888 dispersion)

Vehicles

Model.cfg

Model.cfg is the place where we describe the basic parts of a game model (i.e. its P3D file). It is divided into two classes: CfgSkeletons & CfgModels.
