Question

我正在研究一个简单的游戏教程。当我按下按钮以提高速度时，播放器消失了；而如果我将Y / x值加到了它，它就会按需工作。我认为我的问题与代码的密钥发布部分有问题有关。无论如何，如果有人可以帮助我，那将是理想的选择。谢谢

public void keyPressed(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.Player) {
            //Key Events for player 1
            if(key == KeyEvent.VK_W) tempObject.setY(tempObject.getY() -2);
            if(key == KeyEvent.VK_S) tempObject.setVelY(2);
            if(key == KeyEvent.VK_A) tempObject.setVelX(2);
            if(key == KeyEvent.VK_D) tempObject.setVelX(-2);
        }
        if (tempObject.getId() == ID.Player2) {
            //Key Events for player 2
            if(key == KeyEvent.VK_UP) tempObject.setVelY(-5);
            if(key == KeyEvent.VK_DOWN) tempObject.setVelY(5);
            if(key == KeyEvent.VK_RIGHT) tempObject.setVelX(5);
            if(key == KeyEvent.VK_LEFT) tempObject.setVelX(-5);
        }

    }

}
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.Player) {
            //Key Events for player 1
            if(key == KeyEvent.VK_W) tempObject.setVelY(0);
            if(key == KeyEvent.VK_S) tempObject.setVelY(0);
            if(key == KeyEvent.VK_A) tempObject.setVelX(0);
            if(key == KeyEvent.VK_D) tempObject.setVelX(0);
        }
        if (tempObject.getId() == ID.Player2) {
            //Key Events for player 2
            if(key == KeyEvent.VK_UP) tempObject.setVelY(0);
            if(key == KeyEvent.VK_DOWN) tempObject.setVelY(0);
            if(key == KeyEvent.VK_RIGHT) tempObject.setVelX(0);
            if(key == KeyEvent.VK_LEFT) tempObject.setVelX(-0);
        }

    }

}

播放器1的'W'键按下代码将更改垂直位置，而不是速度。

您可能只用“ W”按钮进行测试，这会使播放器移出屏幕吗？

Java keyRelease似乎不起作用
