?

maphardness ? [?]

Default: 100, Defines how much a map will deform from impacts. Higher values mean less deformation, negative values will result in negative deformation (really funny looking)

notDeformable bool

Default: false,Setting it to 1 means that no explosions can deform the map.

gravity ? [?]

Default: 130, The force of gravity in units/sec^2

tidalStrength ? [?]

Default: 0,The amount of energy which will be given by tidal generators.

maxMetal float [?]

Default: 0.02, How much metal a map square with the maximum metal value gives.

extractorRadius ? [?]

Default: 500, The radius of effect that a single extractor will extract from. If two radii intersect, both extractors will suffer from reduced output.

voidWater bool

Default: false, Voidwater means there will be no water plane, and all parts of the map under water will be completely transparent, to show the skybox through the map. For example, check Apophis_v2

autoShowMetal bool

Default: true, Defines wether the metal map (F4 mode) is shown automatically when a mex is queued for placement.

smf

local mapinfo = {
   ...
   smf = {
      minheight = 1000,
      maxheight = -300,
      smtFileName0 = "",

      smtFileName.. = "",
      smtFileNameN = "",
   },
   ...
}

minheight int [?]

Overrides the minimum map height specified while compiling. Compile time height used if undefined

maxheight int [?]

sound

local mapinfo = {

      reverb = {
         ...
      },
   },
   ...
}

preset string

Default: "default", Sets the _reverb_ preset (= echo parameters), passfilter (the direct sound) is unchanged. To get a list of all possible presets check: EFXPresets.cpp

Hint: You can change the preset at runtime via:

• /tset UseEFX [1|0]
• /tset snd_eaxpreset preset_name (may change to a real cmd in the future)
• /tset snd_filter %gainlf %gainhf (may " " " " " " " " )

passfilter

Note, you likely want to set these tags due to the fact that they are _not_ set by `preset`! So if you want to create a muffled sound you need to use them.

local mapinfo = {
   ...
   sound = {
      ...
      passfilter = {
         gainlf = 1.0,
         gainhf = 1.0,
      },
      ...
   },
   ...
}

gainlf float [?]

Default: ?, ?

gainhf float [?]

damage int [?]

Default: 0, Number of hit points per game frame (30 frames per second) a unit will be damaged if it is in the water. i wonder if this can be made to give life...?

repeatX ? [?]

Default: ?, effects the filing frequency of the watertexture

repeatY ? [?]

Default: ?, effects the filing frequency of the watertexture

absorb rgb

Default: {0.0, 0.0, 0.0}, How fast different colors (RGB in order) are absorbed by the water. Can be used to make the water look murky at deeper sections and so on. How this works: the waterabsorb value for the color channel gets multiplied by the depth of the water at a point, and this product gets subtracted from WaterBaseColor, until WaterMinColor is reached. Example: WaterAbsorb is 0.01, for the red channel, and we want to know how much red will be left in the water at a Spring elevation of -100, since 0.01*100= 1 , at this depth, there will be no more red component in the water, unless WaterMinColor is higher than 0 on the red channel.

baseColor rgb

Default: {0.0, 0.0, 0.0}, The color of the water just beneath the surface plane. This is the starting color from which deeper waters will absorb more color. The values are in the order Red, Green, Blue.

surfaceColor rgb

Default: {0.75, 0.8, 0.85}, The color of the water surface. Mostly affects the colors of the reflections off the top of the water. Has no effect on bump mapped water!

surfaceAlpha float [0.0-1.0]

Default: 0.55, Transparency of the water surface. 0 meaning almost fully transparent water plane(low amount of reflections visible), and 1 being nearly opaque (massive amount of reflections).

diffuseColor rgb

Default: value, This specifies the diffuse color of the water body. WARNING: use of this tag disables the effect of WaterAbsorb , in fact, this tag does nothing but disable WaterAbsorb. Avoid.

specularColor rgb

Default: {0.5, 0.5, 0.5}, ?

fresnelMin ? [?]

: Default: 0.2, ?

fresnelMax ? [?]

: Default: 0.3, ?

fresnelPower ? [?]

: Default: 4.0, ?

reflectionDistortion ? [?]

Default: ?, How much the surface should distort reflections that are cause by waves not being level: ergo it adds more choppyness to your reflections sensible from 0 to 20

blurBase ? [?]

Default: ?, Something to do with blur, but it just seems to cause banding with values under 2 and corruption with values above 10

blurExponent float [?]

Default: ?, How much reflections on water surface should be blurred together with the water surface, lower values meaning clearer reflections, (0.2-5) Warning: above 5 seems to cause water corruption

perlinStartFreq ? [?]

Default: 8, Wave sizes, smaller = big waves, sensible: [1,20] (influence the wave sizes)

perlinLacunarity ? [?]

Default: 3, Defines the size of the perlin waves, small values being big waves ([0.2,5] is sensible)

perlinAmplitude float [?]

Default: 0.9, Base stillness of water surface, 0 is dead still, 1 is 'windy' .This doesnt affect the bump texture depth, besides the fact that this disables the bump texture when set to 0

windSpeed ? [?]

Default: ?, does nothing yet

shoreWaves bool

Default: ?, ?

forceRendering bool

Default: ?, ?

will have to ask about those undefined tags
