JavaFX Hausaufgaben [duplizieren]
Diese Frage ist ein genaues Duplikat von:
JavaFX Kopien derselben Animation erstellen 1 Antwortch freue mich darauf, diese Hausaufgaben zu erledigen. Ich habe ein Programm, das bis zu 5 "FanPanes" anzeigt, bei denen sich ein Fan dreht. Sie können einen Schieberegler verwenden, um die Geschwindigkeit der Lüfter zu steuern. Mit den Schaltflächen können Sie die Lüfter stoppen, wiedergeben und die Richtung der Lüfter umkehren.
Ich habe Probleme, herauszufinden, wie mein Schieberegler ("slider2" ist das, was ich für ihn aus der Klasse FanPane verwenden möchte) die Anzahl der Blades aktualisiert, die der Lüfter anzeigt. Ich möchte in der Lage sein, zwischen 1 und 10 Klingen anzuzeigen.
Auch ich habe Probleme damit, meine Fans richtig auszurichten. Ich hatte es zuvor richtig und jetzt, da ich diese neuen Schieberegler hinzugefügt habe, sind meine Klingen in meinen Kreisen nicht richtig ausgerichtet.
Hier ist mein Code:
