Hi ilteris,
Hmm, this looks fairly weird, though there is a workaround: if by chance
you set the fill of a Sprite to be 0xFF (totally white) and want to
apply a new colour, instead of playing with offsets and multipliers, use
the .color property. Something like this:
package {
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.geom.ColorTransform;
public class ColorTransforma extends Sprite {
var _sprite:Sprite;
var color:ColorTransform;
public function ColorTransforma() {
_sprite = new Sprite();
_sprite.graphics.lineStyle(1, 0xFF);
_sprite.graphics.beginFill(0xFF);
_sprite.graphics.drawRect(0, 0, 100, 100);
_sprite.graphics.endFill( );
addChild(_sprite);
_sprite.addEventListener(MouseEvent.MOUSE_DOWN,
onMouseDown);
color = _sprite.transform.colorTransform;
_sprite.transform.colorTransform = color;
}
public function changeColor() {
color.color = 0xAABBCC;
_sprite.transform.colorTransform = color;
}
private function onMouseDown(event:MouseEvent):void {
changeColor();
trace("yay");
}
}
}
Cheers,
Petro

Re: [Flashcoders] [as3] colorTransform
Thanks Petro. It's interesting that if I set the this line
_sprite.graphics.beginFill(0xFF); it doesn't work but if I set it
like _sprite.graphics.beginFill(0xAABBCC); it works. Does anyone has
any idea why?

Hi ilteris,
Not completely sure what you want to do but assuming you want to change
the colour of the sprite upon mouse click you'd have to set the offsets
to something greater than zero. Say you want to change the colour of the
shape to blue, than your code would look something like below (mind the
value of the .blueOffset property):
package {
import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.events.Event;
import flash.geom.ColorTransform;
public class ColorTransforma extends Sprite {
var _sprite:Sprite;
var color:ColorTransform;
public function ColorTransforma() {
_sprite = new Sprite();
_sprite.graphics.lineStyle( );
_sprite.graphics.beginFill(0xAABBCC);
_sprite.graphics.drawRect(0, 0, 100, 100);
_sprite.graphics.endFill( );
addChild(_sprite);
_sprite.addEventListener(MouseEvent.MOUSE_DOWN,
onMouseDown);
color = _sprite.transform.colorTransform;
_sprite.transform.colorTransform = color;
}
public function changeColor() {
color.redOffset = 0;
color.greenOffset = 0;
color.blueOffset = 255;
_sprite.transform.colorTransform = color;
}
private function onMouseDown(event:MouseEvent):void {
changeColor();
trace("yay");
}
}
}
Cheers,
Petro
