Java イメージの滑らかな動きを実現するにはbooleans
、その状態からアクションを設定してトリガーする必要があることを理解しました。
実行ループで設定しようとしましたが、スプライトが動きません。私はそれをダバグしてみましたが、すべてのメソッドの中に入るので、何が間違っているのかわかりません。
public void run(){
while (running){
go();
repaint();
System.out.println("The game runs");
try {
Thread.sleep(1000/60);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
//PAINT GRAPHICS
public void paintComponent (Graphics g){
super.paintComponent(g);
g.drawImage(bg, 0, 0, this);
g.drawImage(sprite, cordX, cordY, this);
}
//LOAD IMAGES
public void load (){
try {
String bgpath = "res/bg.png";
bg = ImageIO.read(new File (sfondopath));
String spritepath = "res/sprite.png";
sprite = ImageIO.read(new File (spritespath));
} catch (IOException e) {
e.printStackTrace();
}
}
//MOVEMENT
public void go(){
cordX += vX;
cordX += vY;
}
public void gameupdate(){
vX=0;
vY=0;
if (down) vY = speed;
if (up) vY = -speed;
if (left) vX = -speed;
if (right) vX = speed;
}
public void keyPressed(KeyEvent ke) {
switch (ke.getKeyCode()) {
//if the right arrow in keyboard is pressed...
case KeyEvent.VK_RIGHT: {
down = true;
}
break;
//if the left arrow in keyboard is pressed...
case KeyEvent.VK_LEFT: {
up = true;
}
break;
//if the down arrow in keyboard is pressed...
case KeyEvent.VK_DOWN: {

}
gameupdate();
}
public void keyReleased(KeyEvent ke) {
switch (ke.getKeyCode()) {
