Malerei Flash CS3: Echtzeit-Löschen-Werkzeug

Montag, 11. Februar 2008

Ausgehend von der Codes in Paint erstellen in Flash CS3 vorgesehen, und die Durchführung kleiner Änderungen, kann sie wesentlich zu verbessern, um das Werkzeug "löschen". Hinzufügen einer Form nicht sichtbar ist, können Sie es als einen "Plan" zu laufen die draw() in Füllmethode verwenden "löschen". Wie im Beispiel unten, nachdem Sie etwas zu zeichnen, halten Sie die Strg-Taste und die Wirkung von "Löschen" erscheint nun in Echtzeit.

Sie haben eine neue Form, erase_shape nicht sichtbar hinzugefügt (noch nicht gefallen ist jede addChild()

  2. / / Form, nicht sichtbar ist, die für die "Annullierung"
  3. Shape = new Shape ( ) ; var erase_shape: Shape = new Shape ();

In dem Teil des Codes, der für Design nimmt wurde eingeführt, um die Strg-Taste gedrückt, wenn Kontrolle und ist genau der betreffenden Form erase_shape und die Bitmap kopiert:

  2. . lineTo ( e . localX , e . localY ) ; erase_shape. Grafiken. lineTo (and. localX, und. localy);
