GetColorFromString

This function will extract Red, Green, Blue and Alpha values from a hex string you provide it. These strings follow the same format as used in HTML, with addition of the Alpha values.

Syntax

int int int int getColorFromString ( string theColor )

Required Arguments

• theColor: A string containing a valid color code.

Valid strings are:

• • #RRGGBB: Colors specified, Alpha assumed to be 255.
  • #RRGGBBAA: All values specified.
  • #RGB: Shortened form, will be expanded internally to RRGGBB, as such it provides a smaller number of colors.
  • #RGBA: As above, shortened - each character is duplicated.

For example:

• • #FF00FF is Red: 255, Green: 0, Blue: 255, Alpha: 255
  • #F0F is Red: 255, Green: 0, Blue: 255, Alpha: 255 (the same as the example above)

8* '#34455699 is Red: 52, Green: 69, Blue: 86, Alpha: 153

All colors used must begin with a # sign.

Returns

Returns four integers in RGBA format, with a maximum value of 255 for each. Each stands for red, green, blue, and alpha. Alpha decides transparancy where 255 is opaque and 0 is transparent. false is returned if the string passed is invalid (for example, is missing the preceeding # sign).

Example

This example will set the blip attached to a player to a color they specify by typing set_my_color [color] in the console.

addCommandHandler ( "set_my_color", "setPlayerBlipColor" )
function setPlayerBlipColor ( playerSource, commandName, colorString )
    red, green, blue, alpha = getColorFromString ( colorString ) -- convert the color to numbers
    playerBlip = getBlipAttachedTo ( playerSource ) -- find the blip attached to the player
    if ( playerBlip and red != false ) -- check a blip is attached to the player and that a valid color was specified
        setBlipColor ( playerBlip, red, green, blue, alpha ) -- set the player's blip color
    end
end
