Hi, just to preface, I’m pretty new to AS3 and having a hard time using external classes.
I’m using a class that I converted from AS2 to AS3 using Patrick Mineault’s converter: http://www.5etdemi.com/convert/index.php
The original AS2 class:
/**
* Colour handling routines
* Culled from many places:
* - http://www.actionscript.org/forums/showthread.php3?t=15155
*
* @version 1.0
*/
class Colours extends Object {
/**
* Convert RGB values to hexadecimal number
* @param Number r Red value
* @param Number g Green value
* @param Number b Blue value
* @return Number RGB as a hex value
* @access public
*/
static function rgb2hex ( r:Number, g:Number, b:Number ):Number {
return ( r << 16 | g << 8 | b );
}
/**
* Convert a hex number into rgb values
* @param Number hex_col Hex colour to convert
* @return Object Object with r, g and b properties
* @access public
*/
static function hex2rgb ( hex_col:Number ):Object {
var red:Number = hex_col >> 16;
var green_blue:Number = hex_col - ( red << 16 );
var green:Number = green_blue >> 8 ;
var blue:Number = green_blue - ( green << 8 );
return ({r:red, g:green, b:blue});
}
/**

* @return Object Object with h, s and v properties
* @return Object Object with h, s and v properties

static function hex2hsv ( hex_col:Number ):Object {
var rgb:Object = Colours.hex2rgb( hex_col );
return Colours.rgb2hsv( rgb.r, rgb.g, rgb.b );
}

static function hsv2hex ( hue:Number, sat:Number, val:Number ):Number {
var rgb:Object = Colours.hsv2rgb( hue, sat, val );
return Colours.rgb2hex( rgb.r, rgb.g, rgb.b );
}

In the main swf I have imported the class:
import convertcolors.Colours;
On publishing I get no errors.
However, I don’t really understand how to talk to the class to return some converted colour variables.
Here’s my attempt:
//test convert
var hex_col = 0xffffff;
var convertedcol = Colours.hex2hsv(hex_col);
trace(convertedcol);
the trace returns “[object Object]”
What am I doing wrong? Is the AS2 to AS3 conversion part of the problem (aside from my ignorance of how to use it)?
Any help would be appreciated.
Thanks
