将jLabel移到jPanel中的其他位置(类似Pacman的游戏) [英] Moving jLabel to a different place in the jPanel (Pacman like game)
问题描述
我正在制作类似pacman的游戏，到目前为止，我只是从网格开始.我开始使用网格，但是我需要弄清楚如何将某些东西移动到网格中的其他位置，以便当用户单击或我的幻影移动时，它将显示在屏幕上.我该如何移动?我尝试了很多不同的方法，但是没有一种对我有用.
I'm making a game like pacman and so far I am just starting with the grid. I got the grid started but I need to figure out how to move something to a different place in the grid so that when the user clicks or my ghosts move, it will display on the screen. How do I make it move? I have tried a bunch of different ways but none worked for me.
import java.awt.*;
import javax.swing.*;
import javax.swing.border.BevelBorder;
public class GUI {
public static void main(String[] args) {
final JFrame f = new JFrame("Frame Test");
GridLayout Layout = new GridLayout(50,50);
JPanel panel = new JPanel(new GridLayout(50, 50, 1, 1));
//Not sure if I need this or not?
//panel.setLayout(new GridBagLayout());
//first set of black
for (int i = 0; i < 1000; i++) {
JLabel a = new JLabel(new ImageIcon("black-square.jpg"), JLabel.CENTER);
panel.add(a);
}
//adds pacman
JLabel b = new JLabel(new ImageIcon("pacman.png"), JLabel.CENTER);
panel.add(b);
//next set of black
for (int i = 0; i < 1000; i++) {
JLabel c = new JLabel(new ImageIcon("black-square.jpg"), JLabel.CENTER);
panel.add(c);
}
//do the thing
f.setContentPane(panel);
f.setSize(1000, 1000);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
}
}
推荐答案
首先查看如何使用Swing计时器
您将要遇到的下一个问题是容器处于LayoutManager的控制之下.虽然可以使用它来实现移动，但是它会很块状，因为每个组件都会跳出单元格.
The next problem you're going to have is the fact that the container is under the control of a LayoutManager. While it's possible to achieve movement using this, it will be blocky, as each component will jump cells.
如果要平滑移动，则必须设计自己的布局逻辑，这可能会非常复杂.
If you want smooth movement, you're going to have to devise your own layout logic, this can be very complicated.
同样，您应该瞄准的是保持游戏的虚拟"视角.这样，您无需与UI进行大量比较即可了解迷宫的形状和角色的位置.然后，您应该简单地呈现此虚拟"视图或模型的状态
None the less, what you should be aiming for is maintaining the a "virtual" view of the game. This allows you to know the shape of the maze and the position of the characters without need to do a lot of comparisons with the UI. You should then simply render the state of this "virtual" view or model
已更新为VERY BASIC示例
这是一个基本示例，它使用GridLayout和setComponentZOrder移至面板周围的组件...没有碰撞检测，并且"AI"很可悲...
This is a basic example, which uses a GridLayout and setComponentZOrder to move to components about the panel...There is no collision detection and the "AI" is pathetic...
