Titel Rotationsgeschwindigkeit bei Flash-Menü |
  |
|
Hallöle
ich hab vor einiger Zeit ein fertiges Flash-Menü erhalten, das leicht angepasst werden sollte für eine Homepage.
Bilder drehen sich wie auf einem Karusell, werden unscharf und kleiner, wenn sie in den Hintergrund gelangen und bewegen sich je nach Position des Mauszeigers mit.
Das nervige an dem Script ist die Rotationsgeschwindigkeit, wenn die Maus die Flash-Datei zur Seite hin verlässt. Dann drillert das Ding, dass man nix mehr erkennen kann.
Ich hab jetzt versucht den Code anzupassen, allerdings hatte das den Nachteil, dass sich das auf die gesamte Rotationsgeschwindigkeit ausgewirkt hat. Sprich: Nach dem Laden rotiert das ganze entweder gar nicht oder viel zu langsam.
Vielleicht kann mir jemand weiterhelfen, was ich ändern muss?
Hier meine Änderungen, ab //rot -= (Stage.width/2-_xmouse)/10000*turningspeed; :
| Code: |
//CHANGEABLE VARIABLES
//image dimensions
imageWidth = 112;
imageHeight = 75;
//span when animation has finished
xxspan = 200;
yyspan = 45;
//Starting span before moving to center
xspan = 5*xxspan;
yspan = 5*yyspan;
//scale when totally at the back (in %)
minimumscale = 25;
//turningspeed
turningspeed = 4;
//use a focal blur
useFocalBlur = true;
focalBlurValue = 2;
//margin from center of carousel where mouse position has no effect on turning
marg = 50;
