好的,以下是一个简单的Java程序,用于控制王者荣耀移动轮盘:
```java
import java.awt.*;
import java.awt.event.*;
public class MobileControls extends Frame implements KeyListener, FocusListener {
boolean left = false;
boolean right = false;
boolean up = false;
boolean down = false;
public MobileControls() {
addKeyListener(this);
addFocusListener(this);
setTitle("王者荣耀移动轮盘");
setSize(200, 200);
setVisible(true);
}
public void keyPressed(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_LEFT:
left = true;
break;
case KeyEvent.VK_RIGHT:
right = true;
break;
case KeyEvent.VK_UP:
up = true;
break;
case KeyEvent.VK_DOWN:
down = true;
break;
}
redraw();
}
public void keyReleased(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_LEFT:
left = false;
break;
case KeyEvent.VK_RIGHT:
right = false;
break;
case KeyEvent.VK_UP:
up = false;
break;
case KeyEvent.VK_DOWN:
down = false;
break;
}
redraw();
}
public void keyTyped(KeyEvent e) {}
public void focusGained(FocusEvent e) {
redraw();
}
public void focusLost(FocusEvent e) {
left = false;
right = false;
up = false;
down = false;
redraw();
}
public void paint(Graphics g) {
Dimension d = getSize();
int x = d.width / 2;
int y = d.height / 2;
int r = 40;
g.drawOval(x - r, y - r, r * 2, r * 2);
if (left) {
g.drawLine(x - r, y, x - r - 10, y);
}
if (right) {
g.drawLine(x + r, y, x + r + 10, y);
}
if (up) {
g.drawLine(x, y - r, x, y - r - 10);
}
if (down) {
g.drawLine(x, y + r, x, y + r + 10);
}
}
public void redraw() {
repaint();
}
public static void main(String[] args) {
MobileControls controls = new MobileControls();
}
}
```
在这个程序中,我们使用了Java的`KeyListener`和`FocusListener`接口来获取键盘输入,并用`Graphics`来绘制移动轮盘。我们定义了四个布尔变量,分别表示左、右、上、下四个方向是否被按下。
在`keyPressed()`和`keyReleased()`方法中,我们根据键盘输入的方向键来更新对应的布尔变量,并调用`redraw()`方法重绘移动轮盘。在`focusGained()`和`focusLost()`方法中,我们在获得或失去焦点时清除所有方向的状态,并重新绘制移动轮盘。在`paint()`方法中,我们根据各方向的状态来绘制出方向箭头。
最后,在`main()`方法中,我们实例化了`MobileControls`类,以调用`MobileControls`构造函数并启动程序窗口。
