Java Libgdx Actor未检测到的触摸输入

我正在寻找触摸检测。下面显示的代码是我在应用程序中设置圆圈所做的操作。我想检测这个圆上的触摸，而不是周围或整个纹理。奇怪的是触摸没有被检测到，在任何地方我都检测不到 圆圈类：

public class Circle_Obj extends Actor{
    private Vector2 position;
    private float radius;

    private com.badlogic.gdx.math.Circle circle;
    private Texture texture;

    public Circle_Obj(float x, float y, float radius) {

        position = new Vector2(x,y);
        this.radius = radius;

        circle = new com.badlogic.gdx.math.Circle(x,y,radius);
        texture = new Texture(Gdx.files.internal("texture.png"));

        addListener(new InputListener(){
            @Override
            public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
                Gdx.app.log("TOUCHED", " TOUCHED ");
                return true;
            }
        });

    }

    @Override
    public void draw(Batch batch, float parentAlpha) {
        batch.draw(texture,0, 0);
}
}

public class GameScreen implements Screen {
    private Stage stage;
    private Circle_Obj circle_obj;

    public GameScreen() {
        circle_obj = new Circle_Obj(Static_values.Width/2, Static_values.Height/2, Static_values.Width / 100 * 10);

        stage = new Stage(new FitViewport(Static_values.Width/3, Static_values.Height/3));
        stage.addActor(circle_obj);

        Gdx.input.setInputProcessor(stage);

    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        stage.draw();    
        }
    @Override
    public void dispose() {
        stage.dispose();
        }
/** other methods **/
}

屏幕类别：

public class Circle_Obj extends Actor{
    private Vector2 position;
    private float radius;

    private com.badlogic.gdx.math.Circle circle;
    private Texture texture;

    public Circle_Obj(float x, float y, float radius) {

        position = new Vector2(x,y);
        this.radius = radius;

        circle = new com.badlogic.gdx.math.Circle(x,y,radius);
        texture = new Texture(Gdx.files.internal("texture.png"));

        addListener(new InputListener(){
            @Override
            public boolean touchDown(InputEvent event, float x, float y, int pointer, int button) {
                Gdx.app.log("TOUCHED", " TOUCHED ");
                return true;
            }
        });

    }

    @Override
    public void draw(Batch batch, float parentAlpha) {
        batch.draw(texture,0, 0);
}
}

public class GameScreen implements Screen {
    private Stage stage;
    private Circle_Obj circle_obj;

    public GameScreen() {
        circle_obj = new Circle_Obj(Static_values.Width/2, Static_values.Height/2, Static_values.Width / 100 * 10);

        stage = new Stage(new FitViewport(Static_values.Width/3, Static_values.Height/3));
        stage.addActor(circle_obj);

        Gdx.input.setInputProcessor(stage);

    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        stage.draw();    
        }
    @Override
    public void dispose() {
        stage.dispose();
        }
/** other methods **/
}

您可以在circle类中使用libgdx的触控检测。只有触控的circle才会受到影响

    public boolean is_touched() {
    if (Gdx.input.justTouched()) {
        float xx = Gdx.input.getX();
        float yy = Gdx.input.getY();
        float x = position.x;
        float y = position.y;
        return (xx - x) * (xx - x) + (yy - y) * (yy - y) < radius * radius;
    }
}

当两个圆重叠且用户触摸重叠区域时，也可以忽略其中一个被触摸的圆

if (Gdx.input.justTouched()) {
                float xx = Gdx.input.getX();
                float yy = Gdx.input.getY();
                if (circle0.is_touched(xx, yy)) {
                    // do something about circle0
                }
                else if (circle1.is_touched(xx, yy)) {
                    // do something about circle1
                }
                else if (circle2.is_touched(xx, yy)) {
                    // do something about circle2
                }
            }

要检测添加到舞台中的演员的触摸，该演员的方法

hit

被称为（）

---

如果从Actor继承，则需要设置边界，否则将无法单击/触摸！。 只需设置边界以匹配演员包含的纹理

    //add this Set bounds the x, y, width, and height
    circle_obj.setBounds(0, 0,texture.getWidth(), texture.getHeight());

您是否尝试过“stage=newstage（）”；它不起作用编辑：“>radius*radius”是错误的，正确的是“@Override public Actor hit (float x, float y, boolean touchable) { if (touchable && getTouchable() != Touchable.enabled) return null; return (x - position.x)*(x- position.x) + (y - position.y)*(y - position.y) < radius*radius ? this : null; }

    //add this Set bounds the x, y, width, and height
    circle_obj.setBounds(0, 0,texture.getWidth(), texture.getHeight());
