In taught you to play games --JAVA GUI Sokoban (two) , we made the interface, this blog, we will try to move the character to achieve a Sokoban.
1. The role of mobile
We need to write a class monitor button, so that when we press to move around up and down about it.
Wherein, the key code is a value corresponding through System.out.println (code); we can easily obtain the corresponding key numbers we
/**
* 内部游戏按键监听类
*/
class PanelListenner extends KeyAdapter {
// 当按键按下
public void keyPressed(KeyEvent e) {
int code = e.getKeyCode();
switch (code) {
case KeyEvent.VK_UP:
break;
case KeyEvent.VK_DOWN:
break;
case KeyEvent.VK_LEFT:
break;
case KeyEvent.VK_RIGHT:
break;
case 87:
// w
break;
case 65:
// a
break;
case 83:
// s
break;
case 68:
// d
break;
default:
break;
}
}
}Keys well, we need to move ah
So, we need to make a move method, put the key inside the monitor
Which playerx coordinates for the role and playery
Move (1); shall go up.
/**
* 角色移动
* @param direction 方向 1234wasd
*/
private void Move(int direction) {
// TODO Auto-generated method stub
switch (direction) {
// 0墙 1地板 2空箱子 3 箱子 4箱子点 5出生点
case 1:
playerx -= 1;
break;
case 2:
playery -= 1;
break;
case 3:
playerx += 1;
break;
case 4:
playery += 1;
break;
default:
break;
}
}Then we add the listener in the constructor. Was added and movement method in the listener class
However, still can not move, this is how it happened? In fact, ah, although we did a way to move, but we do not have to refresh the screen. So we need to do a thread to constantly refresh the interface can be achieved.
2. Refresh panel
New brush wire panels in succession Thread. Refresh panel once every 0.01 seconds. Wherein 10 is 10ms (milliseconds). Adjustable.
package cn.edu.caztc.sokobangame;
import javax.swing.JPanel;
public class UpdateThread extends Thread{
JPanel panel;
public UpdateThread(JPanel panel) {
this.panel = panel;
}
@Override
public void run() {
while(true){
panel.repaint();
try {
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
} Integration code, complete moving effect

3. collision judgment
Let's call it the collision judgment, although our role to move a success. But unscrupulous moving it is not good. We want to add restrictions.
Let's write a check method to determine whether it can be moved.
/**
* 检查能不能走，前方有墙或者两个箱子超界等
*
* @param direction 方向 1234wasd
* @return
*/
boolean check(int direction) {
switch (direction) {
case 1:
//判断1.超界 2.前面是墙 3.前面是箱子或者空箱子 再前面是箱子或者墙或者空箱子
if (playerx==0) {
return false;
}else if (map1[playerx-1][playery][0]==0) {
return false;
}else if (map1[playerx-1][playery][0]==2||map1[playerx-1][playery][0]==3) {
if (map1[playerx-2][playery][0]==2||map1[playerx-2][playery][0]==3||map1[playerx-2][playery][0]==0) {
return false;
}
}
break;
case 2:
if (playery==0) {
return false;
}else if (map1[playerx][playery-1][0]==0) {
return false;
}else if (map1[playerx][playery-1][0]==2||map1[playerx][playery-1][0]==3) {
if (map1[playerx][playery-2][0]==2||map1[playerx][playery-2][0]==3||map1[playerx][playery-2][0]==0) {
return false;
}
}
break;
case 3:
if (playerx==17) {
return false;
}else if (map1[playerx+1][playery][0]==0) {
return false;
}else if (map1[playerx+1][playery][0]==2||map1[playerx+1][playery][0]==3) {
if (map1[playerx+2][playery][0]==2||map1[playerx+2][playery][0]==3||map1[playerx+2][playery][0]==0) {
return false;
}
}
break;
case 4:
if (playery==17) {
return false;
}else if (map1[playerx][playery+1][0]==0) {
return false;
}else if (map1[playerx][playery+1][0]==2||map1[playerx][playery+1][0]==3) {

}Integrate this method into the code, although able to achieve limited functionality. But he did not Sokoban ah
so: We move to modify the method so that it can be achieved with some judgment Sokoban
