This include makes a conversion between hex color (0xFF0000, for example) to their equivalent vehicle color id.

Function:

pawn Код:

HexColorToVehicleColor(color, ColorFormat:format = RGBA);

* Returns the nearest vehicle color id. format must be RGBA, ARGB, or RGBA.

Example:

pawn Код:

#define RED 0xFF0000FF // RGBA
#define GREEN 0x00FF00 // RGB

// set color1 to RED and color2 to GREEN
ChangeVehicleColor(vehicleid, HexColorToVehicleColor(RED), HexColorToVehicleColor(GREEN, RGB));

new someColorFromSomeWebpage = 0xFAB2AFCC;
printf("equivalent to %x: %d", someColorFromSomeWebpage, HexColorToVehicleColor(someColorFromSomeWebpage));

code:

pawn Код:

// by lleps
enum ColorFormat {
    RGBA,
    ARGB,
    RGB

// %0 means src and %1 byte number (starting from zero)
#define getByteN(%0,%1) ((%0 >> (%1*8)) & 0xFF)

No, it's not perfect. It will look at the closer color, based on their RGB components.
