如果玩家 2 向另一个方向移动，则玩家 1 停止移动

Question

如果我向上移动我的玩家 1 和玩家 2，假设我按下玩家 1 的向下键，我的玩家将停止向上移动。我找不到问题。有人可以帮助我并解释我做错了什么吗？

package game;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
public class KeyInput extends KeyAdapter{
private Handler handler;
private boolean [] keyPressed = new boolean [4];
public KeyInput(Handler handler){
this.handler = handler;
}
public void keyPressed(KeyEvent e){
int key = e.getKeyCode();
keyPressed[0]= false;
keyPressed[1]= false;
keyPressed[2]= false;
keyPressed[3]= false;
for(int i = 0; i <handler.object.size(); i++){
GameObject tempobject= handler.object.get(i);
if (tempobject.getId()== ID.Player1){
if (key == KeyEvent.VK_UP){tempobject.setSpeedy(-7); keyPressed[0] = true;}
if (key == KeyEvent.VK_DOWN){tempobject.setSpeedy(7); keyPressed[1] = true;}
}
if(tempobject.getId()== ID.player2)
if (key == KeyEvent.VK_W){tempobject.setSpeedy2(-7); keyPressed[2] = true;}
if (key == KeyEvent.VK_S){tempobject.setSpeedy2(7); keyPressed[3] = true;}
}
if(key == KeyEvent.VK_ESCAPE)System.exit(1);
}
public void keyReleased(KeyEvent e){
int key = e.getKeyCode();
for(int i = 0; i <handler.object.size(); i++){
GameObject tempobject= handler.object.get(i);
if (tempobject.getId()== ID.Player1){
if (key == KeyEvent.VK_UP) keyPressed[0] = false;
if (key == KeyEvent.VK_DOWN) keyPressed[1] = false;
if(!keyPressed[0] && !keyPressed[1])tempobject.setSpeedy(0);
}
if (tempobject.getId()== ID.player2){
if (key == KeyEvent.VK_W) keyPressed[2] = false;
if (key == KeyEvent.VK_S) keyPressed[3] = false;
if(!keyPressed[2] && !keyPressed[3])tempobject.setSpeedy2(0);
}
}
}
}

Answer 1

这可能与此有关：

keyPressed[0]= false;
keyPressed[1]= false;
keyPressed[2]= false;
keyPressed[3]= false;

这样，只要按下任何键，其他键就会设置为 false，即使它们可能仍被按住。
