Weapon and ItemPackages

Overview

Below you'll find the majority of parameters available in CRYENGINE, which can be used by weapons, ammo and other item scripts.

The default location for these files is: GameSDK\Scripts\Entities\Items\XML\

Please refer to the shipped Rifle.xml file which outlines the structure and many useful parameters used in a real example weapon.

Items

Weapons, accessories, equipment, etc.

Root

Code\GameSDK\GameDll\WeaponSystem.cpp
Code\CryEngine\CryAction\ItemSystem.cpp

ParamTypeDescription
name<string>Name for the item. Needs to match the item filename. For example, Rifle.xml uses item name="Rifle".
inherit<string>Inherit script values from another weapon. Useful for doing weapon skin modifications where the only thing defined in the custom weapon is the geometry.
class<string>Class identifier for weapon C++ code which gives access to various parameters and functionality.
category<string>Used for inventory management. Primary, Secondary, Special, Explosive, etc. These are used for controller mapping. See ItemSharedParams.cpp GetItemCategoryType.
priority<int>Used for inventory management, a lower priority weapon will appear first when scrolling through inventory.
weaponParams<bool>If true, loads basic shared weapon parameters to be used in the script. Should always be true for weapons.
Items (accessories/attachments/etc) don't require many of these params and therefore don't require the weaponParams to be true.

Recoil

Code\GameSDK\GameDll\Recoil.cpp

ParamTypeDefaultDescription
max_recoil<float>0.0Max_recoil is an arbitrary value which is mapped onto the maxx and maxy and is referenced by the attack.
attack<float>0.0Attack is the fraction of the max_recoil added on with each bullet fired, so effectively attack is the fraction of the maxx and maxy added on with each shot. As an example if max_recoil is 1 (as it usually is for clarity) and maxy is 3.0 and attack is 0.33 then the first shot causes the sights to recoil upwards 1 degree, the second shot causes the sights to continue to climb now up 2 degrees and the third and all subsequent shots hold the sights at 3 degrees above the initial aim point. However, its not quite that simple because we also have decay.
first_attack<float>0.0First_attack is only applied to the first bullet, it can be used to give an extra large initial attack and then use a lower attack for the subsequent shots, typically to prevent people tapping fire to be really accurate.
decay<float>0.65Decay is the time in seconds it takes for the max_recoil to be reduced to zero. If max_recoil is 1 and decay is 1.0 second then every 10th of a second the max_recoil would be reduced by 0.1. The rate must be taken into account of course. At rate 600 the gun fires 10 bullets per second. If attack is set to 0.1 and decay is set to 1.0 then every tenth of a second the max_recoil is reduced by 10% or 0.1 attack. So in this case each shot causes 10% of the total recoil to be applied but the sights then return to 0 recoil just as the next bullet is fired, so the sights do not climb steadily in the Y whilst the trigger is held down. If decay is increased slightly then attack has not returned to 0 before the next bullet is fired so the sights slowly climb as the trigger is held down until the attack reaches the max_recoil.
end_decay<float>0.0End_decay is the time it takes for the max_decay value to return to zero once firing ceases.
recoil_time<float>0.0The length of time decay will apply after a shot.
maxx<float>8.0Maxx is the maximum recoil deviation in degrees along the x-axis (upwards). This is influenced by the <hints>.
maxy<float>4.0Maxy is the maximum recoil deviation in degrees upwards in the y-axis (sideways). This is influenced by the <hints>.
tilt<float>0.0Applies a rotation to the recoil to tilt the camera/HUD. The higher the number, the more rotation that is applied.
randomness<float>1.0Randomness is added to each hint when they are applied to the x and added or subtracted from the y recoil (should be added or subtracted to x as well).
impulse<float>0.0Value defines the amount of physical impulse when firing. Firing direction is calculated and then impulse is applied to the weapon owner. If a character is holding this weapon, the character also receives the impulse.
recoil_crouch_m<float>0.85Recoil_crouch_m is the modifier to recoil when player is in crouched stance. If this is greater than 1.0, the recoil in Crouch will be less than the recoil in Stand stance.
This value is applied to the amount of decay reduction per frame and increasing the decay per frame reduces the recoil.
recoil_jump_m<float>1.5Recoil_jump_m is the modifier to recoil when jumping (or falling, essentially if the player is in the air). If this is less than 1.0, the recoil will be greater in the air than the recoil while on the ground.
This value is applied to the amount of decay reduction per frame and increasing the decay per frame reduces the recoil.
recoil_holdBreathActive_m<float>0.5Recoil_holdBreathActive_m is the modifier to recoil when player is holding their breath. If this is less than 1.0, the recoil while holding breath will be less than the standard recoil.

RecoilShake

Code\GameSDK\GameDll\FireModePluginParams.cpp

ParamTypeDefaultDescription
rotateShake<vec3>0,0,0Amount to rotate the camera on the X,Y,Z axis.
shiftShake<vec3>0,0,0Amount to shift the camera on the X, Y, Z axis.
frequency
<float>1.0How frequently to apply the shift/rotation. '2' will mean it's applied every 2 seconds.
time<float>0.1Time taken to achieve the full amount of shift/rotation. '3' will mean it takes 3 seconds to reach maximum XYZ values and return to normal.
randomness<float>0.0Add randomness to all values.

Spread

Code\GameSDK\GameDll\Recoil.cpp

ParamTypeDefaultDescription
min<float>0.015Minimum spread (cone size) in all directions.
max<float>0.0Maximum spread (cone size) in all directions, excluding modifiers.
attack<float>0.95Attack is the amount the cone size increases with each bullet until the max is reached.
decay<float>0.65Time taken for the attack to reduce to zero. Is active whenever your spread is above minimum, but is more noticeable when not firing.
end_decay<float>0.65End_decay is the time to reduce the attack to 0 once firing stops.
speed_m<float>0.25Amount of spread added while moving. Multiplies the current velocity by the amount stated and then adds it to the attack.
This can take attack above the max spread. As an example if the player is moving at 5m/s and the Speed_m is set to 0.2 then the attack will be increased by 1.
speed_holdBreathActive_m<float>0.25Additional modifier placed on top of speed_m, used when the 'hold breath' function is active.
rotation_m<float>0.35Amount of spread added while rotating (turning, pitching, etc).
spread_crouch_m<float>0.85Spread_crouch_m is a modifier that alters the spread whilst in Crouch stance. The lower this is below 1 the greater the reduction.
spread_jump_m<float>1.5Spread_jump_m is a modifier that alters the spread whilst jumping (or falling, essentially if the player is in the air). The higher this is above 1 the greater the increase.
spread_slide_m<float>1.0Spread_slide_m is a modifier that alters the spread whilst in sliding state. The lower this is below 1 the greater the reduction.
spread_holdBreathActive_m<float>1.0Additional modifier which affects final spread result, used when the 'hold breath' function is active. The lower this is below 1 the greater the reduction.
