java如何为键盘输入制作不同的动画
我正在用爪哇制作一个自上而下的射击游戏,我有一个固定的玩家,他可以左右转动,可以向移动到中间(玩家所在的位置)的敌人开枪。当我的球员转身时,我为每一边做了不同的脸,但我不知道如何在使用箭头键时切换脸。这是我的主面板:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
public class FinalPanel extends JPanel
{
private static final int FRAME = 1600;
private static final Color BACKGROUND = new Color(255, 255, 255);
private Player player;
private ImageIcon faces;
private ImageIcon playerFace = new ImageIcon("PlayerUpImage.png");
private BufferedImage myImage;
private Graphics myBuffer;
private Timer timer;
public FinalPanel()
{
myImage = new BufferedImage(FRAME, FRAME, BufferedImage.TYPE_INT_RGB);
myBuffer = myImage.getGraphics();
addKeyListener(new Key());
setFocusable(true);
}
private class Listener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
ImageIcon player = new ImageIcon("PlayerUpImage.png");
myBuffer.drawImage(player.getImage(), 800, 800, null);
repaint();
}
}
public void paintComponent(Graphics g)
{
super.paintComponenet(g);
g.drawImage(myImage, 0, 0, getWidth(), getHeight(), null);
}
private class Key extends KeyAdapter//The arrow keys make the player change directions and it replaces his face with a different animation to show the change in direction
{
public void keyPressed(KeyEvent e)
{
if(e.getKeyCode() == KeyEvent.VK_W)
{
playerFace = new ImageIcon("PlayerUpImage.png");
}
if(e.getKeyCode() == KeyEvent.VK_S)
{
playerFace = new ImageIcon("PlayerDownImage.png");
}
if(e.getKeyCode() == KeyEvent.VK_A)
{
playerFace = new ImageIcon("PlayerLeftImage.png");
}
if(e.getKeyCode() == KeyEvent.VK_D)
{
playerFace = new ImageIcon("PlayerRightImage.png");
}
repaint();
}
}
}
玩家等级:
import java.awt.*;
import javax.swing.*;
public class Player
{
//Private fields for player class
private int myX;
private int myY;
private int myXWidth;
private int myYWidth;
public Player()
{
myX = 775;
myY = 775;
myXWidth = 50;
myYWidth = 50;
}
public Player(int x, int y, int xWidth, int yWidth)
{
myX = x;
myY = y;
myXWidth = xWidth;
myYWidth = yWidth;
}
//I borrowed this health code from: https://stackoverflow.com/questions/9834609/how-to-make-a-player-class-that-holds-lives-inheritance//
int liveCount = 10;
public boolean damage() {
--liveCount;
return isDead();
}
public boolean isDead() {
return liveCount < 1;
}
public void boostLives(int moreLives) {
liveCount += moreLives;
}

public int getX()

return myX;
}
public int getY()
{
return myY;
}
public int getXWidth()
{
return myXWidth;
}
public int getYWidth()
{
return myYWidth;
}
//Modifier Methods//
public void setX(int x)
{
myX = x;
}
public void setY(int y)
{
myY = y;
}
public void setXWidth(int xWidth)
{
myXWidth = xWidth;
}
public void setYWidth(int yWidth)
{
myYWidth = yWidth;
}
}

我有一些建议可能会有所帮助:
不要使用可变面,而是使用名为playerFace的图像图标,默认方向为向上
你的作画方法可能是这样的
在按下键的方法中,您所要做的就是更改播放器图像并调用repaint方法,以便面板再次调用paintComponent方法:
最好是将playerFace作为Player类的属性,并使用getter方法来获取playerFace方向(因此将playerFace设置为Player的变量)。但这是为了让你开始
您还需要设置一个框架,而不是使用当前的变量框架
