Please be aware of our Arma 3 modding license: http://community.bistudio.com/wiki/Arma_3_Modding_License


Additional functionality compared to A2/OA

  • Slotable weapon accessories
  • Custom reload animations
  • Adjustable sights
  • Underwater weapons
  • Ammo changes on fly and on hit
  • Rotating muzzle-flash
  • Explosion shielding


Model requirements {p3d}

  • proxies for slotable accessories
    • muzzle accessory should be on proxy \A3\data_f\proxies\weapon_slots\MUZZLE
    • optics should be on proxy \A3\data_f\proxies\weapon_slots\TOP
    • side accessory should be on proxy \A3\data_f\proxies\weapon_slots\SIDE
    • bipod accessory should be on proxy \A3\data_f_mark\proxies\weapon_slots\UNDERBARREL
    • all these proxies could be redefined in cfgWeapons >> Weapon >> WeaponSlotsInfo >> XXX >> linkProxy parameter where XXX is the slot name
  • selections for folding iron sights
    • You need to create selections and axes for iron sights if You want them folded once the optics is put on the weapon
    • Front part should be named ForeSight with ForeSight_axis in memory lod
    • Rear part should be named BackSight with BackSight_axis in memory lod
  • adjustable sights for grenade launchers
    • there needs to be a selection that is going to rotate (in case of collimator sights), default naming is OP
    • this selection needs to have an axis in memory lod, default naming is OP_axis
    • there needs to be a focus point, the best place is the red dot of collimator, with memory point OP_look by default and several points for eye, usually OP_eyeX where X is the number of the point. Good practice is to place them in same distance form focus point


Model config changes {model.cfg}

  • custom reload animation have a good use of newly added parameter unHideValue for hide type of animations - you are now able to make asymmetrical animations eg. for hiding of magazine:

{model.cfg}

class magazine_hide
{
	type = "hide";
	source = "reloadMagazine";
	selection = "magazine";
	minValue = 0.000000;
	maxValue = 1.00000;
	hideValue = 0.220;
	unhideValue = 0.550;
};
  • the animations could look a bit better by simply adding a translation for the magazine and adding an axis for that in model - magazine should translate at first, then disappear, appear and translate back

{model.cfg}

class magazine_reload_move_1
{
	type = "translation";
	source = "reloadMagazine";
	selection = "magazine";
	axis = "magazine_axis";
	minValue = 0.145;
	maxValue = 0.170;
	offset0 = 0.0;
	offset1 = 0.5;
};
  • foldable iron sights use hasOptics controller

{model.cfg}

class BackSight_optic
{
	type = "rotation";
	source = "hasOptics";
	selection = "BackSight";
	axis = "BackSight_axis";
	memory = 1;
	minValue = 0.0000000;
	maxValue = 1.0000000;
	angle0 = 0.000000;
	angle1 = (rad 90);
};
  • new animation controllers zeroing1 and zeroing2 take values from discreteDistance[] of first and second muzzle of the weapon. The value is index number of current zeroing in the array starting with zero (that means the first value is 0, second is 1, the last is number of discrete distances plus one). It might be used for iron sights of the weapon if desired but better use is for UGL collimator sights rotation:

{model.cfg}

class OP_ROT
{
	type="rotation";
	source = "zeroing2";		// use second muzzle zeroing for rotation
	sourceAddress = "loop";		// loop when phase out of bounds
	selection = "OP";			// selection we want to rotate
	axis = "OP_axis";			// has its own axis
	minValue = 0;
	maxValue = 3;				// this weapon has array with 4 distances
	angle0 = "rad 0";
	angle1 = "rad 65";
};
  • rotating muzzle flashes are done using a new animation source ammoRandom which changes it is value every time weapon is fired. Various degrees of rotation may be set up by using correct muzzle flash shape and minValue maxValue combination.

{model.cfg}

class MuzzleFlashROT
{
	type = "rotationX";
	source = "ammoRandom";		// use ammo count as phase for animation
	sourceAddress = "loop";		// loop when phase out of bounds
	selection = "zasleh";		// selection we want to rotate
	axis = "";					// no own axis - center of rotation is computed from selection
	centerFirstVertex = true;	// use first vertex of selection as center of rotation
	minValue = 0;
	maxValue = 4;				// rotation angle will be 360/4 = 90 degrees
	angle0 = "rad 0";
	angle1 = "rad 360";
};


New config parameters {config.cpp}

Slotable weapons

  • Available slots are defined in each weapon but are usually inherited from a parent weapon. They are stored as classes in class WeaponSlotsInfo which contains the slots and parameters for inventory
    • Mass is a new unit used to describe weight and volume of an object used. Each container has a set capacity in the same units.
    • allowedSlots[] is an array of slot numbers where you may put the weapon. 701 stands for vest, 801 stands for uniform, 901 stands for backpack
    • each weapon slot is a separate subclass in class WeaponSlotsInfo
      • parameter linkProxy defines a proxy in weapon model for said slot (see standard names on top)
      • parameter displayName describes a mouse-over name of slot in Inventory
      • array compatibleItems[] lists possible accessory placeable into that slot. Most weapons are able to have any RIS equipment, but eg. muzzle accessory differs according to caliber.
    • external classes CowsSlot and PointerSlot are used for standard optics and side accessory. That means these classes are outside cfgWeapons and changeable for all weapons at once.
class SlotInfo;
class CowsSlot : SlotInfo
{
	// targetProxy
	linkProxy = "\A3\data_f\proxies\weapon_slots\TOP";

	// display name
	displayName = $STR_A3_CowsSlot0;

	// class names with items supported by weapon 
	compatibleItems[] = {"optic_Arco","optic_aco", "optic_ACO_grn","optic_hamr","optic_Holosight"};
}; 
class PointerSlot : SlotInfo
{
	// targetProxy
	linkProxy = "\A3\data_f\proxies\weapon_slots\SIDE";

	// display name
	displayName = $STR_A3_PointerSlot0;

	// class names with items supported by weapon 
	compatibleItems[] = {"acc_flashlight","acc_pointer_IR"}; 
};

class cfgWeapons
{
	class myWeapon
	{
		class WeaponSlotsInfo
		{
			mass = 4; // default mass of a weapon
			class MuzzleSlot : SlotInfo
			{
				// targetProxy
				linkProxy = "\A3\data_f\proxies\weapon_slots\MUZZLE";

				// display name
				displayName = "Muzzle Slot";

				// class names with items supported by weapon
				compatibleItems[] = {}; // moved to each weapon
			};
			class CowsSlot: CowsSlot {};
			class PointerSlot: PointerSlot {};
			allowedSlots[] = {901}; // you simply cannot put this into your pants
		};
	};
};

Muzzle accessories

  • suppressors are configured as a weapon inheriting some item abilities from class ItemCore
  • the class itself consists only from scope, displayName, picture and model, there is a separate subclass ItemInfo with all the required parameters
    • there is subclass MagazineCoef inside class ItemInfo with parameter initSpeed - this is just a multiplier of initSpeed of weapon's magazine
    • subclass AmmoCoef of class ItemInfo has more parameters for the ammo shoot through the suppressor:
      • hit is the coefficient of hit of original ammo
      • visibleFire, audibleFire, visibleFireTime and audibleFireTime are coefficients for detection upon shooting the weapon
      • higher cost coefficient should make AI think more about shooting the suppressed weapon
      • typicalSpeed and airFriction coefficients change the ballistic characteristics of the ammo
    • there are alternate muzzleEnd and alternativeFire directly inside class ItemInfo to have different muzzle effects origin and muzzle flashes
class Mode_SemiAuto;
class cfgWeapons
{
	class ItemCore;
	class InventoryMuzzleItem_Base_F;	
	class myMuzzleAccessory
	{
		scope = 2;
		displayName = "My Muzzle Accessory";

		picture = "\A3\weapons_F\Data\UI\myMuzzleAccessory_CA.paa";
		model = "\A3\weapons_f\acc\myMuzzleAccessory";	
		
		class ItemInfo: InventoryMuzzleItem_Base_F
		{	
			soundTypeIndex = 1; // index of sound in sounds[] in weapon modes (inherited 1 from parent class)

			class MagazineCoef
			{
				initSpeed = 0.8;
			};

			class AmmoCoef
			{
				hit = 0.8;
				visibleFire = 0.3;
				audibleFire = 0.8;
				visibleFireTime = 0.5;
				audibleFireTime = 1.0;
				cost = 1.0;
				typicalSpeed = 0.8;
				airFriction = 1.0;
			}; 

			muzzleEnd = "zaslehPoint";		// memory point in muzzle supressor's model
			alternativeFire = "Zasleh2";	// class in cfgWeapons with model of muzzle flash	
	
			class MuzzleCoef
			{
				dispersionCoef = 1.0f;
				artilleryDispersionCoef = 1.0f;

				fireLightCoef = 0.1f;

				recoilCoef = 1.0f;
				recoilProneCoef = 1.0f;

				minRangeCoef = 1.0f; minRangeProbabCoef = 1.0f;
				midRangeCoef = 1.0f; midRangeProbabCoef = 1.0f;
				maxRangeCoef = 1.0f; maxRangeProbabCoef = 1.0f;
			};
		};
	};
};

Sound Values

  • Starting from patch 1.24 (dev version 1.23 from 23.6. 2014 on), there is a change how sounds are handled because of sound suppressors:
    • Weapon without any muzzle accessory has a soundTypeIndex equal to 0, while it could be any number (by default 1) according to suppressor type used.
    • array parameter sounds[] of fire mode is used to chose what sound subclass is going to be used - it is sounds[] = {StandardSound, SilencedSound}; by default
    • classes defined in previous parameter are subclasses of a fire mode with various sound parameters: weaponSoundEffect, soundBegin[], soundClosure{}
class MyWeapon: Rifle_Base_F
{
	class Single: Mode_SemiAuto
	{			
		sounds[] = { StandardSound, SilencedSound };

		class BaseSoundModeType // this base class has base definitions that both standard and silenced sounds will inherit (sound of closure stays the same no matter what muzzle accessory is used)
		{
			weaponSoundEffect = "DefaultRifle";

			closure1[] = { "A3\sounds_f\weapons\closure\closure_rifle_2", db-12, 1, 10 };
			closure2[] = { "A3\sounds_f\weapons\closure\closure_rifle_3", db-12, 1, 10 };
			soundClosure[] = { closure1, 0.5, closure2, 0.5 };
		};

		class StandardSound: BaseSoundModeType // Sounds inside this class are used when soundTypeIndex = 0, according to sounds[]
		{
			begin1[] = { "A3\Sounds_F\weapons\SMG_02\SMG_02_st_1b", db0, 1, 500 };
			begin2[] = { "A3\Sounds_F\weapons\SMG_02\SMG_02_st_2b", db0, 1, 500 };
			begin3[] = { "A3\Sounds_F\weapons\SMG_02\SMG_02_st_3b", db0, 1, 500 };
			soundBegin[] = { begin1, 0.33, begin2, 0.33, begin3, 0.34 };
		};

		class SilencedSound: BaseSoundModeType // Sounds inside this class are used when soundTypeIndex = 1, according to sounds[]
		{
			begin1[] = { "A3\sounds_f\weapons\silenced\silent-07", db-1, 1, 200 };
			begin2[] = { "A3\sounds_f\weapons\silenced\silent-08", db-1, 1, 200 };
			soundBegin[] = { begin1, 0.5, begin2, 0.5 };
		};
		// various other fire mode parameters
	};
};

Optics

  • in addition to default parameters mentioned in muzzle accessories class, there is weaponInfoType to choose a correct resource for weapon info directly inside optic class
    • there is the same ItemInfo subclass but with different parameters
      • don't forget that ItemInfo inherits some parameters from InventoryOpticsItem_Base_F (eg. muzzlePos and muzzleEnd) in case you rename the memory points
    • parameter opticType is used for balancing the optics for specific fire modes (should be further described by balancing crew)
    • modelOptics is the 2D model for selected optics
    • subclass OpticsModes works the same way it used to work in A2/OA
class cfgWeapons
{
	class ItemCore;
	class InventoryOpticsItem_Base_F;	
	class myOpticsAccessory
	{
		scope = 2;
		displayName = "My Optics Accessory";

		picture = "\A3\weapons_F\Data\UI\myOpticsAccessory_CA.paa";
		model = "\A3\weapons_f\acc\myOpticsAccessory";	
		weaponInfoType = "RscOptics_myOptics"; 
		
		class ItemInfo: InventoryOpticsItem_Base_F
		{	
			mass = 7;
			modelOptics = "\A3\Weapons_f\acc\reticle_MyOptics_F"; 
			class OpticsModes
			{
				class MyOptics
				{
					opticsID = 1;
					useModelOptics = true;
					opticsPPEffects[] = { "OpticsCHAbera1", "OpticsBlur1" };
					opticsZoomMin = 0.0555;
					opticsZoomMax = 0.1300;
					opticsZoomInit= 0.1300;
					discreteDistance[] = {100,300,400,500,600,700,800,900,1000};
					discreteDistanceInitIndex = 1;	
					distanceZoomMin = 100;
					distanceZoomMax = 1000;	
					nFovLimit = 0.07;
					discreteFov[] = { 0.1300, 0.0555 };
					discreteInitIndex = 0;						
					modelOptics[] = { "\A3\Weapons_f\acc\reticle_MyOptics_F", "\A3\Weapons_f\acc\reticle_MyOptics_z_F" }; 
					memoryPointCamera = "opticView";
					visionMode[] = {"Normal","NVG"};
					opticsFlare = true;
					opticsDisablePeripherialVision = true;
					cameraDir = "";
				};
				class IronOnTopOfMyOptics: MyOptics
				{
					opticsID = 2;
					useModelOptics = false;
					opticsFlare = false;
					opticsDisablePeripherialVision = false;
					opticsZoomMin = 0.375; 
					opticsZoomMax = 1.1;
					opticsZoomInit = 0.75;
					memoryPointCamera = "eye";
					visionMode[] = {};
					discretefov[] = {};
				};	
			};
		};
	};
};

Side Accessory

  • the class of side accessory is made the same way as for muzzle accessory
    • subclass ItemInfo contains some specific parameters, but they work the same way as they did in A2/OA
class cfgWeapons
{
	class ItemCore;
	class InventoryFlashLightItem_Base_F;	
	class mySidesAccessory
	{
		scope = 2;
		displayName = "My Sides Accessory";

		picture = "\A3\weapons_F\Data\UI\mySidesAccessory_CA.paa";
		model = "\A3\weapons_f\acc\mySidesAccessory";	
		
		class ItemInfo: InventoryFlashLightItem_Base_F
		{
			mass = 9;
			class Pointer
			{
				irLaserPos = "laser pos";
				irLaserEnd = "laser dir";
			};
			class FlashLight{};		
		};
	};
};

Custom reload animations

  • parameter reloadAction is now for both a magazine and the weapon.
    • if it is not defined for any of them, default reload is played.
    • if the parameter is defined for the weapon but isn't defined for a magazine, reloadAction for weapon is played upon reloading said weapon
    • if the magazine has reloadAction defined, the action selected by this parameter is played every time (not depending on weapon). This ensures different reloads for different magazines of one weapon (eg. UGLs)
  • the action chosen by reloadAction is played according to config of animations for said soldier (action in CfgMovesMaleSdr leads to a state in CfgGesturesMale for default soldier), different target states could be defined for different action maps (eg. there could be a different reload gesture for crouch and prone with rifle)
class CfgMovesBasic
{
	class DefaultDie;
	class ManActions
	{
		reloadMyWeapon = "reloadMyWeapon";	
	};
};

class CfgGesturesMale
{
	class Default;
	class States
	{
		class reloadMyWeapon: Default
		{
			file = "\A3\anims_f\Data\Anim\Sdr\wop\erc\stp\rld\rfl\reloadMyWeapon.rtm";
			looped = 0;
			speed = 0.400000;
			mask = "handsWeapon";
			headBobStrength = 0.200000;
			headBobMode = 2;
			rightHandIKBeg = 1;
			rightHandIKEnd = 1;
			leftHandIKCurve[] = { 0, 1, 0.050000, 0, 0.950000, 0, 1, 1 };
		};
	};
};

class cfgWeapons
{
	class myWeapon
	{
		reloadAction = "reloadMyWeapon";
	};
};

Underwater weapons

  • weapons with canShootInWater set to 1 are able to shoot under water
    • parameter soundBeginWater[] has the same use as soundBegin[] and defines what sounds and with what probability is going to be played while shooting under the water surface, both of them are defined per fire mode:
class Mode_SemiAuto;

class cfgWeapons
{
	class myWeapon
	{
		modes[] = { "Single" };	// this example weapon has just one fire mode
		canShootInWater = 1;	// allows to shoot under water
		class Single: Mode_SemiAuto
		{		
			begin1[] = { "A3\sounds_f\weapons\myWeapon\myWeapon_st_1b.wav", db5, 1, 900 };
			begin2[] = { "A3\sounds_f\weapons\myWeapon\myWeapon_st_2b.wav", db5, 1, 900 };
			begin3[] = { "A3\sounds_f\weapons\myWeapon\myWeapon_st_3b.wav", db5, 1, 900 };
			soundBegin[] = { begin1, 0.33, begin2, 0.33, begin3, 0.34 }; // all three sounds have roughly the same probablity
			beginwater1[] = { "A3\sounds_f\weapons\myWeapon\underwater_myWeapon_st_1b.wav", db0, 1, 200 };
			beginwater2[] = { "A3\sounds_f\weapons\myWeapon\underwater_myWeapon_st_2b.wav", db5, 1, 200 };
			beginwater3[] = { "A3\sounds_f\weapons\myWeapon\underwater_myWeapon_st_3b.wav", db5, 1, 200 };
			soundBeginWater[] = { beginwater1, 0.33, beginwater2, 0.33, beginwater3, 0.34 }; // all three sounds have roughly the same probablity
		};
	};
};
  • underwater ammo has some different characteristics
    • waterFriction is underwater equivalent of airFriction and supercavitating ammunition has this close to zero. Standard ammo doesn't have this set and that means it is set to -0.4 by default (ie. stops nearly right after entering water)
    • timeToLive for underwater ammo is rather low to let it be harmless after some 40 meters
    • the fancy bubble effect is done by having effectFly set to AmmoUnderwater, you'll try to modify it to work even on ground and we all know it
class cfgAmmo
{
	class BulletBase;
	class myAmmo: BulletBase // for myWeapon
	{
		waterFriction = -0.00096;	// nearly direct line underwater
		timeToLive = 0.12;			// that's enough for 45 meters underwater
		effectFly = "AmmoUnderwater";
	};
};

Ammo changes on fly and on hit

  • there are two new simulations of ammo available mainly for shells and missiles.
  • simulation shotSubmunitions allows to deploy multiple ammo from the parent one upon meeting certain conditions
    • parameter submunitionAmmo defines class of newly created ammo and this could be used multiple times
      • you could set the inherited ammo and it would spread in cone according to submunitionConeAngle and submunitionConeAngleHorizontal (in degrees)
      • Arma 31.68 you can also define multiple sub-munition projectiles and their probability: submunitionAmmo[] = {"MySubammo1",0.8,"MySubammo2",0.2}; (80% of sub-munition will be MySubammo1 and 20% will be MySubammo2)
    • submunitionConeType[] describes pattern of ammo in detail, first part is a distribution function ("random", "randomcenter", "poissondisc", "poissondisccenter", "custom"), second parameter is number of ammo except of custom one, where it is another array of pairs for specific locations
submunitionConeType[] = {"random", 10};
submunitionConeType[] = {"randomcenter", 10};
submunitionConeType[] = {"randomupcone", 10};
submunitionConeType[] = {"poissondisc", 10};
submunitionConeType[] = {"poissondisccenter", 10};
submunitionConeType[] = {"custom", {{0,0}, {-1,0}, {1,0}, {0,-1}, {0,1}} };
    • parameter submunitionAutoleveling affects if cone has the up vector in model space (rotated when lying on steep hill) or always up in world space coord system (replaced by submunitionDirectionType)
    • parameter submunitionDirectionType defines the direction in which the submunition is generated; "SubmunitionModelDirection" retains the parent munition's vector, "SubmunitionAutoLeveling" levels the submunition out horizontally and "SubmunitionTargetDirection" generates the submunition in the direction of the parent's locked target (see PCML from 1.81+). If present the param overrides submunitionAutoleveling parameter.
    • parameter triggerDistance is used to deploy ammo in set 3D distance before expected target
    • parameter triggerTime is used to deploy ammo in set time after being fired
    • parameter triggerOnImpact(bool) is used to deploy ammo after impact
    • parameter deleteParentWhenTriggered (bool) defines if parent munition should be deleted after releasing sub munition
    • parameter submunitionInitialOffset (array) sets spawning offset of submunition. i.e. {0,0,-0.2}; will spawn projectile 20 cm before impact position if it is coupled with SubmunitionModelDirection for example.
    • parameter submunitionInitSpeed sets the submunition init speed directly (in m/s)
    • parameter triggerSpeedCoef is a coefficient of speed of inherited ammo relative to speed of parent ammo
      • Arma 31.68 you can also define the speed as range, with the actual coefficient being selected randomly from within the range: triggerSpeedCoef[] = {0.5,1.0};
    • parameter submunitionParentSpeedCoef is a coefficient of how much speed of the parent munition is retained in the submunition - i.e. submunitionParentSpeedCoef = 0; will spawn submunition exactly at its own submunitionInitSpeed regardless of how fast was the parent munition flying
    • for Artillery computer use array aimAboveTarget[] and aimAboveDefault as a index of the array to set different heights to change the ammo to something different (eg. flare)
class cfgAmmo
{
 	class SubmunitionBase;
	class MyAmmo: SubmunitionBase
	{
		submunitionAmmo = "MySubmunitionAmmo";
		submunitionConeType[] = {"poissondisc", 10};
		submunitionConeAngle = 10;
		triggerDistance = 100;
	};
};
  • simulation shotDeploy is used to change ammo upon impact (eg. change to a mine)
    • it uses the same submunitionAmmo parameter as described above
class cfgAmmo
{
	class ShotDeployBase;
	class Mo_ClassicMineRange: ShotDeployBase
	{
		submunitionAmmo = "APERSMine_Range_Ammo";	// some random mine deployable by a mortar
		airFriction = 0;							// artillery ammo works better without friction
		EffectFly = "ArtilleryTrails";				// some funky effect of smoke trails and stuff
	};
};

Explosion shielding

  • class hitpoints in configuration of all vehicles (including soldiers) has got a new parameter called explosionShielding
    • this parameter simply multiplies inidrectHit taken from explosives (that makes it explosion vulnerability in an effective way) - the higher it is the more damage would selected hitpoint get from the hit
class cfgVehicles
{
	class myVehicle
	{
		class HitPoints
		{
			class HitLFWheel { armor = 0.12; explosionShielding = 0.8; };
		};
	};
};

Weapon inertia

  • inertia coefficient of the weapon is easily set by the inertia parameter, common values are 0.1 for a pistol, 0.5 for a rifle, 0.7 for machinegun and around 1.0 for a launcher
class cfgWeapons
{
	class myWeapon
	{
		// inertia coefficient of the weapon
		inertia = 0.5;
	};
};

Inventory icons overlay method

  • Update 1.40 adds a new functionality for Inventory icons of weapons - using one icon for the weapons and display slot icons as an overlay for that icon.
  • If there is no slot with positive value of iconScale property, the game falls back to old behaviour
  • The icon lower layer of the inventory picture is still defined in property icon of the weapon itself
class cfgWeapons
{
	class myWeapon
	{
		class WeaponSlotsInfo: WeaponSlotsInfo // default accessories for this slot, iconPicture and iconPinpoint is defined in the base class
		{
			class MuzzleSlot: MuzzleSlot
			{
				iconPosition[] = {0.0, 0.45};	// position of the slot icon inside of the weapon icon, relative to top-left corner in {right, down} format
				iconScale = 0.2;				// scale of icon described in iconPicture
				iconPicture = "\A3\Weapons_F\Data\UI\attachment_muzzle.paa"; // icon for selected slot
				iconPinpoint = "Center";		// top, bottom, left, right, center alignment of the icon on snap point
			};
			class CowsSlot: CowsSlot // default accessories for this slot, iconPicture and iconPinpoint is defined in the base class
			{
				iconPosition[] = { 0.5, 0.35 };
				iconScale = 0.2;
			};
			class PointerSlot: PointerSlot // default accessories for this slot, iconPicture and iconPinpoint is defined in the base class
			{
				iconPosition[] = { 0.20, 0.45 };
				iconScale = 0.25;
			};
		};
		icon = "\A3\MyAddon\Rifles\MyRifle\Data\MyRifle_X_CA.paa" // this stays the same as before and is used as a base layer
	};
};

Magazine compatibility groups

  • Update 1.80 added new technology called magazineWells (also known as "magwells") which replaces old, non working magazineGroups. Technology consist from two parts: class CfgMagazineWellsin root config & parameters (array) magazineWell in weapon muzzle. In contrast to old solution, Magazine Wells are using separate class in root config containing all type of magazine wells with list of arrays containing compatible classes. It's possible to add new entries by 3rd party modifications
class cfgWeapons
{
	class arifle_MX_Base_F;
	class rhs_weap_m4_Base : arifle_MX_Base_F
	{ 
		[...]
		// first magazine in array is used as a default magazine in Virtual Arsenal
		// Eden editor ammo crates widget is also using that array to create list of compatible magazine which can be placed in crate
		magazines[] =
		{
			"rhs_mag_30Rnd_556x45_M855A1_Stanag"
		};
		// Link to magazine wells
		magazineWell[] = {STANAG_556x45};
	};
};

// Located in root config
class CfgMagazineWells
{
	class STANAG_556x45
	{
		// Magazines listed by mod
		// It is possible to add new arrays to class but for now inheritance (i.e. STANAG_556x45_New: STANAG_556x45 {};) is not supported 
		RHS_Magazines[] =

Bipods

  • Update 1.42 (Marksmen DLC release) adds a possibility to use #bipods by either utilizing another weapon slot - under barrel - or by using a inbuilt one
    • Bipod as an attachment works exactly the same way as for example muzzle attachment
    • There are two new properties - deployedPivot describing memory point in model around which the weapon pivots while deployed and hasBipod which is self-explanatory
class CfgWeapons
{
	class ItemCore;
	class InventoryUnderItem_Base_F;
	class test_bipod_01_F: ItemCore
	{
		scope		= 2;															// available in Arsenal
		displayName	= "My Little Bipod";											// name of item in Inventory (and Arsenal)
		picture		= "\A3\Weapons_F_Mark\Data\UI\gear_accu_bipod_01_snd_CA.paa";	// icon in Inventory
		model		= "\Samples_f\Test_weapon_01\test_bipod_01_F.p3d";				// path to model

		class ItemInfo: InventoryUnderItem_Base_F
		{
			deployedPivot		= "bipod";	// what point should be used to be on surface while unfolded
			hasBipod			= true;		// bipod obviously has a bipod
			mass				= 10;		// what is the mass of the object
			soundBipodDown[]	= {"A3\Sounds_F_Mark\arsenal\sfx\bipods\Bipod_AAF_down",db-3, 1, 20};	// sound of unfolding the bipod
			soundBipodUp[]		= {"A3\Sounds_F_Mark\arsenal\sfx\bipods\Bipod_AAF_up",db-3, 1, 20};		// sound of folding the bipod
		};
		inertia = 0.2; // how much does the bipod add to inertia of the weapon
	};
};
  • Inbuilt #bipods are much easier, you just need to add deployedPivot and hasBipod properties to the weapon itself
class cfgWeapons
{
	class myWeapon
	{
		deployedPivot		= "bipod";	// what point should be used to be on surface while unfolded
		hasBipod			= true;		// a weapon with bipod obviously has a bipod
		soundBipodDown[]	= { "A3\Sounds_F_Mark\arsenal\sfx\bipods\Bipod_AAF_down", db-3, 1, 20 };	// sound of unfolding the bipod
		soundBipodUp[]		= { "A3\Sounds_F_Mark\arsenal\sfx\bipods\Bipod_AAF_up", db-3, 1, 20 };		// sound of folding the bipod
	};
};
  • The important part about bipods is that the actual model may be animated despite of it being a proxy on a weapon
    • Animation source bipod_legs is used for that, possible values are 0 for weapon not deployed and 1 for weapon deployed
    • The model obviously needs to have a skeleton to work properly
    • Configuration is the same in case of inbuilt bipods, the only difference is in animation source - it is bipod

{model.cfg}

class legs
{
	type			= rotation;
	source			= bipod_legs; // this one is for an attachment, weapon itself would have just bipod
	sourceAddress	= clamp;
	selection		= "bipod_legs";
	axis			= "bipod_legs_axis";
	minValue		= 0;
	maxValue		= 1;
	angle0			= (rad 0);
	angle1			= (rad 90);
};
  • The bipods may have even adjustable length of legs according to actual position
    • Animation source bipod_legs_length is used for that as it returns distance between bipod point and surface in meters (means that 5 centimeters are 0.05 value of the source)
    • Configuration is the same in case of inbuilt #bipods, the only difference is in animation source - it is bipod_length

{model.cfg}

class Leg_L_move // we use different animation for each leg as they are folded by default and rotate while unfolding, this one is for the left one
{
	type		= translation;
	source		= bipod_legs_length;
	selection	= "Leg_L";
	axis		= "Leg_L_axis"; // the axis is part of "bipod_legs" selection in model
	memory		= 1;
	minValue	= 0;
	maxValue	= 0.1;	// this #bipod extends up to 10 centimeters for example
	offset0		= 0;
	offset1		= 1;	// we use axis with length of 10 centimeters, that means translation needs to be multiplied by ten
};

Pistol holsters

  • Update 1.48 adds a possibility to use show pistols inside of holsters of vests that have the holster
    • The vest model should contain proxy leading to \A3\Characters_F\Proxies\pistol_holstered.p3d, the standard position is in sample of vest inside Characters samples, but feel free to move it according to the model
    • As soon as the vest contains the proxy, weapon is going to be shown in it. There are just two properties to adjust the way the weapon shows on the proxy:
      • The standard pistol is P07 which has its center around the trigger. If you want to move the center of your weapon, just create a memory point called holster (according to holsterOffset property in weapon configuration) to serve as new center of the model
      • P07 is even taken as a standard weapon for holster size, you may adjust the scale at which is your gun drawn in the holster with holsterScale property
class Pistol;
class Pistol_Base_F: Pistol
{
	class WeaponSlotsInfo;
};
class MyLittlePistol: Pistol_Base_F
{
	class WeaponSlotsInfo: WeaponSlotsInfo
	{
		holsterOffset = "holster";	// name of a memory point in weapon to serve as zero of the model
		holsterScale = 1;			// scale of gun in holster relative to standard size (0.5 means the gun is 50 % of original size)
	};
};

Magazine Proxies

  • With update 1.78 it is possible to have dynamic magazines using modelSpecial & modelSpecialIsProxy property.


Virtual Arsenal visibility

  • In order to reduce clutter in Virtual Arsenal weapon list, parameter "baseWeapon" was introduced, which filters out all subvariants from the VA.
class cfgWeapons
{
	class myWeapon
	{
		baseWeapon = "myWeapon";
	};
	class myWeapon2: myWeapon
	{
	};
	class myWeapon3: myWeapon
	{
		baseWeapon = "myWeapon3";
	};
};
  • In above example "myWeapon" & "myWeapon3" would be visibile in Virtual Arsenal. Please note, that all 3 weapons can be normally accessed in game and that baseWeapon parameter is only used in Virtual Arsenal
