This function will tell you what color a blip is. This color is only applicable to the default blip icon (
, 
or 
). All other icons will ignore this.
Syntax
int int int int getBlipColor ( blip theBlip )
OOP Syntax Help! I don't understand this!
- Method: blip:getColor(...)
- Counterpart: setBlipColor
Required Arguments
- theBlip: The blip whose color you wish to get.
Returns
Returns four integers in RGBA format, with a maximum value of 255 for each. The values are, in order, red, green, blue, and alpha. Alpha decides the transparancy where 255 is opaque and 0 is fully transparent. false is returned if the blip is invalid.
Example
This example will find all the blips that exist and set them all to white if they aren't white already.
-- Retrieve a table containing all the blips that exist blips = getElementsByType ( "blip" ) -- Loop through the list, storing the blip from the table in the variable blipValue for blipKey, blipValue in ipairs(blips) do -- Retrieve the blip's colors into the variables red, green, blue and alpha red, green, blue, alpha = getBlipColor ( blipValue ) -- If the blip's icon isn't white already if ( red ~= 255 or green ~= 255 or blue ~= 255 or alpha ~= 255 ) then -- Set the blip's color to white setBlipColor ( blipValue, 255, 255, 255, 255 ) end end
