ColorTransform

[mike05]

I'm looking back at some of my old code and I can't seem to figure out why this works....

var myShapeColour:uint = 0x000000;
var myColour:ColorTransform;
myColour = shape_mc.transform.colorTransform;
myColour.color = myShapeColour;
shape_mc.transform.colorTransform = myColour;

Doesn't it seem redundant?

Can someone explain how the colorTransform works?

It must be one of those "update only on direct assignment" properties that only reads the values once.

Yes, as henke37 said, the .colorTransform property cannot be updated by simply changing its properties, it has to be completely re-assigned. That is redundant logically, but internally when you get a reference to .transform.colorTransform you get a copy of the object, not a reference. AS3 is pretty inconsistent in what properties behave like that, for instance .transform.matrix is a copy, but .transform.matrix3D is a reference. Go figure.

Thanks guys, yeah it was just weird to look at it and wrap my head around it. Thanks again!
