In some cases I can’t help thinking that AS3 hasn’t made our live easier.
The same happened with the change that happened from the AS2 setRGB to AS3.
Specifies an RGB color for a Color object.
setRGB
This is what the ActionScript 2.0 Migration has to say about this:
| ActionScript 2.0 | ActionScript 3.0 | Comments |
| setRGB() Method | flash.geom.ColorTransform.color | The RGB color value can be set by using the color accessor property of the ColorTransform class. |
ActionScript 2 example code:
[as]
// AS2 Code
var my_color:Color = new Color(my_mc);
my_color.setRGB(0xFF0000); // my_mc turns red
[/as]
[as]
// AS2 Code (The Color class has been deprecated in favor of the flash.geom.ColorTransform class.)
import flash.geom.ColorTransform;
var colorTrans:ColorTransform = new ColorTransform();
colorTrans.rgb = 0xFF0000;
var trans:Transform = new Transform( my_mc);
trans.colorTransform = colorTrans;[/as]
and the same code in ActionScript 3:
[as]
// AS3 code
import flash.geom.ColorTransform;
// Changes my_mc’s color to red.
var newColorTransform:ColorTransform = my_mc.transform.colorTransform;
newColorTransform.color = 0xff0000;
my_mc.transform.colorTransform = newColorTransform;
[/as]
More code to write, for something that I don’t use very much. The next time I need to change an Objects color I probably need to search the solution on the web…
No, I going to fix this in a neat little package:
Save this file into: ‘nl.matthijskamstra.utils’

And now I hope you will never have to look for it again
Happy AS3 😉
