我正在製作一款遊戲，玩家圖標應該總是按照他走的方向旋轉，但圖標不旋轉爲什麼？下面是他旋轉的方法：爲什麼我的JLabel（圖標）不旋轉？ （RotatedIcon）
public static void turnPlayer(Direction d){
if (pt == Playere.Kaneki){
RotatedIcon ri = new RotatedIcon(new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/Kaneki_walk.png")));;
if (d == Direction.DOWN && p.getDirection() == Direction.RIGHT)
ri.setDegrees(90);
if (d == Direction.LEFT && p.getDirection() == Direction.RIGHT)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.RIGHT)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.LEFT && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.DOWN && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2);
if (d == Direction.DOWN && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.LEFT && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
System.out.println("Went as kaneki!");
playerImage.setIcon(ri);
playerImage.repaint();
RepaintPlayer();
p.setDirection(d);
}
if (pt == Playere.Touka){
RotatedIcon ri = new RotatedIcon(new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/touka_walk.png")));
if (d == Direction.DOWN && p.getDirection() == Direction.RIGHT)
ri.setDegrees(Math.PI/2);
if (d == Direction.LEFT && p.getDirection() == Direction.RIGHT)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.RIGHT)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.LEFT && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.DOWN)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.UP && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.DOWN && p.getDirection() == Direction.LEFT)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
if (d == Direction.RIGHT && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2);
if (d == Direction.DOWN && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2+Math.PI/2);
if (d == Direction.LEFT && p.getDirection() == Direction.UP)
ri.setDegrees(Math.PI/2+Math.PI/2+Math.PI/2);
System.out.println("Went as touka!");
playerImage.setIcon(ri);
playerImage.repaint();
RepaintPlayer();
p.setDirection(d);
}
}
如果需要RepeintPlayer（）方法：
public static void RepaintPlayer(){
if (p.isAttacking() == true){
if (pt == Playere.Kaneki){
ImageIcon img = new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/Kaneki_hit.png"));
playerImage.setIcon(img);
System.out.println("WHY IT NO WORKING????? EVEN DO I PUT THISSS?");
}
if (pt == Playere.Touka){
ImageIcon img = new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/touka_hit.png"));
playerImage.setIcon(img);
}
}else{
if (pt == Playere.Kaneki){
ImageIcon img = new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/Kaneki_walk.png"));
playerImage.setIcon(img);
}
if (pt == Playere.Touka){
ImageIcon img = new ImageIcon(StartMenu.class.getResource("/Schoo/NewGame/touka_walk.png"));
playerImage.setIcon(img);
}
}
MovePlayer(p.getX(), p.getY());
playerImage.repaint();
f.repaint();
}
如果你需要全班同學：

爲什麼不用一個包含Icon的JLabel創建一個簡單的程序，然後像「Left」和「右鍵「將會旋轉圖標。首先了解如何使用圖標。在你最後一個問題中，特別提到你設置了度（而不是弧度） – camickr
