PacmanmethodformoveJavalibGDX

使用libGDX库中的InputProcessor接口和Actor类来实现Pacman移动方法。

代码示例如下：

1. 首先创建一个实现InputProcessor接口的类，用于处理输入事件。代码如下：

public class PacmanInputProcessor implements InputProcessor {
    
    private PacmanActor pacmanActor;
    
    public PacmanInputProcessor(PacmanActor pacmanActor) {
        this.pacmanActor = pacmanActor;
    }
    
    @Override
    public boolean keyDown(int keycode) {
        if(keycode == Keys.UP) {
            pacmanActor.moveUp();
        } else if(keycode == Keys.DOWN) {
            pacmanActor.moveDown();
        } else if(keycode == Keys.LEFT) {
            pacmanActor.moveLeft();
        } else if(keycode == Keys.RIGHT) {
            pacmanActor.moveRight();
        }
        return true;
    }
    
    // 省略其他接口方法的实现
}

2. 创建一个继承自Actor类的PacmanActor类，用于实现Pacman的移动方法。代码如下：

public class PacmanActor extends Actor {
    
    private TextureRegion pacmanTexture;
    private float x;
    private float y;
    
    public PacmanActor(TextureRegion pacmanTexture) {
        this.pacmanTexture = pacmanTexture;
        setWidth(pacmanTexture.getRegionWidth());
        setHeight(pacmanTexture.getRegionHeight());
    }
    
    public void setPosition(float x, float y) {
        this.x = x;
        this.y = y;
        setX(x);
        setY(y);
    }
    
    public void moveUp() {
        y += 10; // 假设每次移动10个像素点
        setY(y);
    }
    
    public void moveDown() {
        y -= 10;
        setY(y);
    }
    
    public void moveLeft() {
        x -= 10;
        setX(x);
    }
    
    public void moveRight() {
        x += 10;
        setX(x);
    }
    
    @Override
    public void draw(Batch batch, float parentAlpha) {
        batch.draw(pacmanTexture, getX(), getY());
    }
}
