Colors

Any place you need to specify a color in the game (at the moment this is just with VECDRAW, HIGHLIGHT. and HUDTEXT) You do so with a rgba color structure defined as follows:

Method 1: Use one of these pre-arranged named colors:

RGB(r,g,b)

This global function creates a color from red green and blue values:

SET myColor TO RGB(r,g,b).

where:

r
A floating point number from 0.0 to 1.0 for the red component.
g
A floating point number from 0.0 to 1.0 for the green component.
b
A floating point number from 0.0 to 1.0 for the blue component.
RGBA(r,g,b,a)

Same as RGB() but with an alpha (transparency) channel:

SET myColor TO RGBA(r,g,b,a).

r, g, b are the same as above.

a
A floating point number from 0.0 to 1.0 for the alpha component. (1.0 means opaque, 0.0 means invisibly transparent).
structure RGBA
Members
Suffix Type Description
:R or :RED scalar the red component of the color
:G or :GREEN scalar the green component of the color
:B or :BLUE scalar the blue component of the color
:A or :ALPHA scalar the alpha (how opaque: 1 = opaque, 0 = transparent) component of the color
:HTML or :HEX string the color rendered into a HTML tag string i.e. “#ff0000”. This format ignores the alpha channel and treats all colors as opaque.

Examples:

SET myarrow TO VECDRAW.
SET myarrow:VEC to V(10,10,10).
SET myarrow:COLOR to YELLOW.
SET mycolor TO YELLOW.
SET myarrow:COLOR to mycolor.
SET myarrow:COLOR to RGB(1.0,1.0,0.0).

// COLOUR spelling works too
SET myarrow:COLOUR to RGB(1.0,1.0,0.0).

// half transparent yellow.
SET myarrow:COLOR to RGBA(1.0,1.0,0.0,0.5).

PRINT GREEN:HTML. // prints #00ff00
HSV(h,s,v)

This global function creates a color from hue, saturation and value:

SET myColor TO HSV(h,s,v).

`More Information about HSV <http://en.wikipedia.org/wiki/HSL_and_HSV>`_,

where:

h
A floating point number from 0.0 to 1.0 for the hue component.
s
A floating point number from 0.0 to 1.0 for the saturation component.
v
A floating point number from 0.0 to 1.0 for the value component.
HSVA(h,s,v,a)

Same as HSV() but with an alpha (transparency) channel:

SET myColor TO HSVA(h,s,v,a).

h, s, v are the same as above.

a
A floating point number from 0.0 to 1.0 for the alpha component. (1.0 means opaque, 0.0 means invisibly transparent).
structure HSVA

The HSVA structure contains all of the suffixes from the RGBA structure in addition to these

Members
Suffix Type Description
:H or :HUE scalar the hue component of the color. It is a value from 0.0 to 360.0
:S or :SATURATION scalar the saturation component of the color. It has a value from 0.0 to 1.0
:V or :VALUE scalar the value component of the color. It has a value from 0.0 to 1.0

Examples:

SET myarrow TO VECDRAW.
SET myarrow:VEC to V(10,10,10).
SET myarrow:COLOR to HSV(60,1,1). // Yellow
SET myarrow:COLOR:S to 0.5. // Light yellow
SET myarrow:COLOR:H to 0. // pink
