Alrighty!
publicvoid rotate(Graphics g,int direction)
{
Image ship = sprite.getImage();
double turnDirection = Math.toRadians(direction);
AffineTransform AF =new AffineTransform();
Graphics2D g2 = (Graphics2D) g;
//g2.drawImage(ship, 0, 0, null);
g2.drawImage (ship, AF.getRotateInstance(turnDirection, this.x,this.y),null);
}
Trying to rotate a ship in my game.
Any suggestions or help you can give?
Thanks! :)
public void rotate(Graphics g, int direction)
{
AffineTransform at = new AffineTransform();
Graphics2D g2 = (Graphics2D) g;
Image ship = sprite.getImage();
angle = angle + direction*15;
double turnRadians = Math.toRadians(angle);
at.translate(-x, -y);
at.rotate(turnRadians);
at.translate(ship.getWidth(null)/2, ship.getHeight(null)/2);
System.out.println(called);
g2.drawImage (ship, at, null);
}
that didn't help much, experiemented a bit.
