Thanks for your responses guys. I'm still stuck on this and I have been
playing around a lot. I can get the number from the decimal format to the
hex string but when I try to convert it to a hex number the colour is
incorrect.
Any advice much much appreciated, this is taking up lots of time.
Thanks:
public function colorIn(o:Object):void
{
trace("===================");
var colA:Array = o.Colors.split(",");
colA.splice(0,1);
for ( var i:uint=1; i<=totSprites-1; i++ ) {
var c:String = colA[i];
trace("string colour:"+c); // e.g. for red: 16711680
//convert to decimal number
var tmpN:Number = Number(c);
trace("decimal:"+tmpN); // traces: 16711680
//convert to string of hex number
var hexStr:String = tmpN.toString(16);
trace("hexStr:"+hexStr); //traces: ff0000
//convert to hex number
var hexNum:Number = parseInt(c, 16);
trace("= = = = = = => hex number:"+hexNum); //traces in decimal format and
wrong number: 376510080
//set mc to color
var mcToCol:* = mainImage["s"+i];
//transform color
var newColorTransform:ColorTransform = mcToCol.transform.colorTransform;
newColorTransform.color = hexNum;
mcToCol.transform.colorTransform = newColorTransform;
};
}
