This reference page was created for Arma 3 v1.60+, some fields may not exist in prior games and versions.

A

access

Integer: Determines the manipulability of the class.

Value Type Description
0 ReadAndWrite Additional values can be added
1 ReadAndCreate Only adding new class members is allowed
2 ReadOnly No modifications enabled
3 ReadOnlyVerified No modifications enabled

All BIS classes are ReadOnlyVerified and can only be inherited into a new class

access = 2; // ReadOnly

AIAvoidStance

Introduced with Arma 3 version 1.60

Integer: Allows restricting the AI from entering prone with two levels of emphasis

Value Description
0 No change in behavior
1 Less preference for going prone - avoid prone (unless stealth or suppressed or *)
2 Almost never going prone - never prone (unless *)
* means commanded, injured, animated, forced, ...

C

character

String: Points to a corresponding CfgSurfaceCharacters entry, which defines the clutter on this surface.

character = "Empty";		// No clutter will be used on this surface
character = "SeabedClutter";	// SeabedClutter defined in CfgSurfaceCharacters will be used on this surface

D

dust

Float: Amount of dust vehicles will create on this surface (higher value = more dust)

dust = 0.75;	// High amount of dust, used for GdtStratisDryGrass
dust = 0.05;	// Almost no dust, used for GdtConcrete

F

files

String: Defines which ground texture and roadway texture filenames this surface will apply to

files = "gdt_grass_green_*";	// Tells the ground texture what surface it corresponds to
files = "surfint_wood_*";		// Tells the texture used in the roadway LOD what surface it corresponds to

From commented configs of BI (binarize\bin)

Caution: wildcard pattern "files" is matched using special purpose matching

* may be used only as last character of the pattern
* matches any string in filename
? matches any single character in filename

when six trailing question-marks are detected "??????", two patterns are matched:
full pattern and short pattern with ?????? omitted

friction

Seems obsolete

Float: Unknown

friction = 0.9;	// Default value, used by all A3 surfaces

G

grassCover

Float: Reduces visibleSize (taken from CfgMovesBasic) of unit for AI visibility movement computations (cannot make fully invisible) - it is NOT about visual drawing

grassCover = 0;		// Used by GdtStratisConcrete, there will be no simulated grass cover at a distance
grassCover = 0.05;	// Used by GdtStratisGreenGrass, there will be some simulated grass cover at a distance

I

impact

String: Defines what particle effect is shown when the surface is hit by a bullet, points to a corresponding entry in CfgAmmo

impact = "hitGroundHard";	// Used by GdtStony, particle effect will be chunks of rock flying when hit
impact = "hitGroundSoft";	// Used by GdtStratisDirt, particle effect will be dirt flying when hit

isWater

Integer: Declares whether the surface is water

isWater = 1;	// Used by SurfWater, declares the surface as water
isWater = 0;	// Used by Default, declares the surface is not water

L

lucidity

Float: how hard to detect a mine on this surface. Default: 1

lucidity = 0.3;	// Used by GdtStratisConcrete
lucidity = 3.5;	// Used by GdtStratisForestPine
lucidity = 150;	// Used by GdtStratisSeabed

M

maxClutterColoringCoef

Float: Defines the maximal coefficient of difference between the color of the surface and clutter (must be greater than or equal to 1)

maxClutterColoringCoef = 1.35;	// Used by GdtStratisConcrete
maxClutterColoringCoef = 1.5;	// Used by GdtBeach

maxSpeedCoef

Float: Defines the maximum speed coefficient on that surface for carEPE simulation. Default is 1

maxSpeedCoef = 1;	// Used by GdtStratisConcrete, no change in speed
maxSpeedCoef = 0.9;	// Used by GdtStratisGreenGrass, 10% reduction in speed
maxSpeedCoef = 0.8;	// Used by GdtStratisForestPine, 20% reduction in speed

For cars also limited by terrainCoef factor defined in cfgVehicles. Max reduction is 50%.

R

restitution

Seems obsolete

Float: Unknown

restitution= 0;	// Used by every surface

rough

Seems disabled in A3.

Float: Defines the roughness of the surface when driving over it in a vehicle (higher value = more bumps). Seems to limit also speed of tanks somewhat

rough = 0.05;	// Used by GdtStratisConcrete, minimal bumps
rough = 0.15;	// Used by GdtMud, fairly bumpy

S

soundEnviron

String: Defines the sound played when walking or driving a vehicle on the surface, points to sounds defined in SoundEnvironExt

soundEnviron = "drygrass";	// Used by GdtGrassDry, dry grass sound
soundEnviron = "gravel";	// Used by SurfRoadDirt, gravel sound
soundEnviron = "int_wood";	// Used by SurfIntWood, weapons fired while on this surface will have a reverb effect.

This value also determines the sound for footsteps inside of a building corresponding for the roadway LOD. It is important to use corresponding textures for surfaces that are indoors or outdoors, as it has an effect on the sound when firing weapons on that surface.

Relates also the sound controllers

soundHit

String: Defines the sound played when the surface is struck by a bullet

soundHit = "concrete";		// Used by GdtStratisConcrete, sound of bullet hitting concrete is played when this surface is hit
soundHit = "soft_ground";	// Used by GdtStratisDirt, sound of dirt is played when this surface is hit

Seemingly valid values:

  • body
  • building
  • concrete
  • default
  • foliage
  • glass
  • glass_armored
  • hard_ground
  • iron
  • metal
  • metal_plate
  • plastic
  • rubber
  • soft_ground
  • water
  • wood

surfaceFriction

Float: Defines the surface friction on this surface (lower value = more friction)

surfaceFriction = 2.5;	// Used by SurfRoadTarmac, highest surface friction value
surfaceFriction = 2;	// Used by SurfRoadConcrete, above average surface friction value
surfaceFriction = 1.8;	// Used by GdtDirt, below average surface friction value
surfaceFriction = 1.5;	// Used by GdtMarsh, low end of surface friction values

T

terrainClutterFactor

Integer: Can enable clutter on roadway when above 0

terrainClutterFactor = 0;	// Default value used by all surfaces, except for Water = 1

tracksAlpha

Seems obsolete

Integer: Defines the alpha value of vehicle tracks

tracksAlpha = 1;	// Default value used by all surfaces

transparency

Seems obsolete

Integer: Unknown

transparency = -1;	// Default value used by all surfaces
