小编jon*_*ash的帖子

我正试图在libgdx游戏中实现触摸滚动.我有一个宽广的图像,是一个房间的全景.我希望能够滚动图像,以便用户可以在房间周围看到.我有它,所以我可以滚动一定的距离但是当注册新的touchDragged事件时,图像被移回原始位置.

这就是我实现它的方式

public class AttackGame implements ApplicationListener {

AttackInputProcessor inputProcessor;
Texture backgroundTexture; 
TextureRegion region;
OrthographicCamera cam;
SpriteBatch batch;
float width;
float height;
float posX;
float posY;

@Override
public void create() {
    posX = 0;
    posY = 0;
    width = Gdx.graphics.getWidth();
    height = Gdx.graphics.getHeight();  
    backgroundTexture = new Texture("data/pancellar.jpg");
    region = new TextureRegion(backgroundTexture, 0, 0, width, height);
    batch = new SpriteBatch();

}

@Override
public void resize(int width, int height) {
    cam = new OrthographicCamera();
    cam.setToOrtho(false, width, height);
    cam.translate(width / 2, height / …
