Java 捕捉到Libgdx光标后，光标消失

我将鼠标设置为“捕捉”

但当此设置打开时，光标消失。 我正在开发一个等轴测2d rts游戏，我真的需要光标被强制留在窗口内，但我显然也需要光标被显示出来。

我正在使用平铺地图绘制地图。

我有一个游戏，我在玩家触地或触地的任何地方/任何时候绘制一个点，如果你抓住光标，它将消失，这是预期的行为

要解决此问题，您必须使用

纹理

、

精灵

或

纹理区域

自己绘制鼠标。下面是一个例子：
绘制光标：

public class MyCursor {

    private TextureRegion cursor;
    private float x, y;

    public MyCursor(TextureRegion cursorRegion) {
        cursor = cursorRegion;
    }

    public void render(SpriteBatch spriteBatch) {
        spriteBatch.begin();
        spriteBatch.draw(cursor, x, y);
        spriteBatch.end();
    }

    public void setPosition(float x, float y) {
        this.x = x;
        this.y = y;
    }
}

public class MyInput extends InputAdapter {

    private OrthographicCamera camera;
    private MyCursor myCursor;

    public MyInput(OrthographicCamera camera, MyCursor myCursor) {
        this.camera = camera;
        this.myCursor = myCursor;
    }

    @Override
    public boolean mouseMoved(int screenX, int screenY) {
        Vector3 temp = camera.unproject(new Vector3(screenX, screenY, 0));
        myCursor.setPosition(temp.x, temp.y);
        return true;
    }
}

public class MyGame extends Game {

    @Override
    public void create() {
        OrthographicCamera camera = new OrthographicCamera();
        TextureRegion cursorRegion = new TextureRegion(new Texture("myCursor.png"));
        MyCursor cursor = new MyCursor(cursorRegion);
        MyInput myInput = new MyInput(camera, cursor);
        Gdx.input.setInputProcessor(myInput);
    }
}

处理输入：

public class MyCursor {

    private TextureRegion cursor;
    private float x, y;

    public MyCursor(TextureRegion cursorRegion) {
        cursor = cursorRegion;
    }

    public void render(SpriteBatch spriteBatch) {
        spriteBatch.begin();
        spriteBatch.draw(cursor, x, y);
        spriteBatch.end();
    }

    public void setPosition(float x, float y) {
        this.x = x;
        this.y = y;
    }
}

public class MyInput extends InputAdapter {

    private OrthographicCamera camera;
    private MyCursor myCursor;

    public MyInput(OrthographicCamera camera, MyCursor myCursor) {
        this.camera = camera;
        this.myCursor = myCursor;
    }

    @Override
    public boolean mouseMoved(int screenX, int screenY) {
        Vector3 temp = camera.unproject(new Vector3(screenX, screenY, 0));
        myCursor.setPosition(temp.x, temp.y);
        return true;
    }
}

public class MyGame extends Game {

    @Override
    public void create() {
        OrthographicCamera camera = new OrthographicCamera();
        TextureRegion cursorRegion = new TextureRegion(new Texture("myCursor.png"));
        MyCursor cursor = new MyCursor(cursorRegion);
        MyInput myInput = new MyInput(camera, cursor);
        Gdx.input.setInputProcessor(myInput);
    }
}

也不要忘记启用输入：

public class MyCursor {

    private TextureRegion cursor;
    private float x, y;

    public MyCursor(TextureRegion cursorRegion) {
        cursor = cursorRegion;
    }

    public void render(SpriteBatch spriteBatch) {
        spriteBatch.begin();
        spriteBatch.draw(cursor, x, y);
        spriteBatch.end();
    }

    public void setPosition(float x, float y) {
        this.x = x;
        this.y = y;
    }
}

public class MyInput extends InputAdapter {

    private OrthographicCamera camera;
    private MyCursor myCursor;

    public MyInput(OrthographicCamera camera, MyCursor myCursor) {
        this.camera = camera;
        this.myCursor = myCursor;
    }

    @Override
    public boolean mouseMoved(int screenX, int screenY) {
        Vector3 temp = camera.unproject(new Vector3(screenX, screenY, 0));
        myCursor.setPosition(temp.x, temp.y);
        return true;
    }
}

public class MyGame extends Game {

    @Override
    public void create() {
        OrthographicCamera camera = new OrthographicCamera();
        TextureRegion cursorRegion = new TextureRegion(new Texture("myCursor.png"));
        MyCursor cursor = new MyCursor(cursorRegion);
        MyInput myInput = new MyInput(camera, cursor);
        Gdx.input.setInputProcessor(myInput);
    }
}

为什么光标需要停留在窗口内？例如，如果用户想要关闭或最小化窗口，他们可以随时选择alt tab或退出。我只需要一个帝国时代的风格设置。谢谢！我不得不将myCursosr.render（spriteBatch）添加到渲染循环中，现在它可以工作了！
