RE: [Swftools-common] _x and _y move everything? (bug?)

[Huub Schaeks]

Hello Jon

I'm no actionscript expert myself, but my guess is that if you put the ".filled person" on the stage like you did, it's just a shape, not a movieclip. Only movieclips have onEnterFrame events and shapes don't have onLoad events either, so I think that when you specify handlers for those events the way you did these handlers get assigned to those events for the stage , which is a movieclip. So the _x and _y refer to the position of the whole stage.

The code below works as I think you intended. What I did  was put the  ".filled person" into a sprite first (renaming it to person_shape) and put that sprite onto the stage. I assigned the handlers explicitly to the 'stage'-events and specified that the "person" sprite was to be moved.

Regards,
Huub

Try http://peachcobbler.uni.cc/persondemo.swf (without the www.) if the other link isn't working. My web host is being retarded. Sorry.

If I compile the following code and load the swf, the arrow keys make all the objects in the movie move. Is this right or should it only move the object that the script is attached to? (the person, but not the box):

(You have to click inside the bounding box to activate keyboard control.)


As far as I understand (I'm a newbie at actionscript, so it's likely I'm wrong), the person.onEnterFrame function is part of the person object, so it should only move the person, and not the box (b1).

It does the same thing if I put person._x and person._y, too.

I am using swftools 0.8.1 on Windows XP SP1. I haven't tried this with the current dev release.
