所以,我刚刚添加了 InputHandler,这样我就可以使用 wasd(上、下、左、右)移动我的屏幕。但是当我尝试它时,我的 spritesheet 被撕裂了,屏幕不会向上或向下移动,只是对角线(左右工作正常),我不知道为什么会这样。我没有任何错误...
package ca.linus.game;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.ArrayList;
import java.util.List;
public class InputHandler implements KeyListener {
public InputHandler(Game game) {
game.addKeyListener(this);
}
public class Key {
private int numTimesPressed = 0;
private boolean pressed = false;
public int getNumTimesPressed() {
return numTimesPressed;
}
public boolean isPressed() {
return pressed;
}
public void toggle(boolean isPressed) {
pressed = isPressed;
if (isPressed) numTimesPressed++;
}
}
public List<Key> keys = new ArrayList<Key>();
public Key up = new Key();
public Key down = new Key();
public Key left = new Key();
public Key right = new Key();
public void keyPressed(KeyEvent e) {
toggleKey(e.getKeyCode(), true);
}
public void keyReleased(KeyEvent e) {
toggleKey(e.getKeyCode(), false);
}
public void keyTyped(KeyEvent e) {
}
public void toggleKey(int keyCode, boolean isPressed) {
if (keyCode == KeyEvent.VK_W) {up.toggle(isPressed);}
if (keyCode == KeyEvent.VK_S) {down.toggle(isPressed);}
if (keyCode == KeyEvent.VK_D) {right.toggle(isPressed);}
if (keyCode == KeyEvent.VK_A) {left.toggle(isPressed);}
}
}
这是我的 InputHandler 文件。
