Change the position of the registration point in Flash CS5

问题

Is there a way to change the position of the registration point inside a Movie Clip using Flash5 ? I've found stuff online for older Flash versions but not CS5.

回答1:

I wasn't aware of that.

As far as I know, all you need to do is:

1. edit the MovieClip(Dobule-click)
2. move the contents of the MovieClip relative to the crosshair on stage

If you want to match the transform point with the registration point:

1. Go one level up
2. Use the Transform Tool(Q)
3. Double-click Transform Tool's circle.

HTH

回答2:

In free transform mode, just move the hollow circle wherever you want and that will set the new registration point.

import flash.display.Sprite;
import flash.events.Event;
import flash.geom.Transform;

var rec:Sprite = new Sprite();
rec.graphics.beginFill(0x00FF00, 1);
rec.graphics.drawRect(-50, -50, 100, 100);
addChild(rec);

var tp:Transform = new Transform(rec);
tp.matrix.tx = 0;
tp.matrix.ty = 0;

trace("X: " + rec.x + " Y: " + rec.y);

rec.x = 250;
rec.y = 250;

trace("X: " + rec.x + " Y: " + rec.y);

addEventListener(Event.ENTER_FRAME, onEnterFrame);
function onEnterFrame(event:Event):void
{
rec.rotation += (Math.PI / 0.1);
}
