我正在尝试编写一个简单的迷宫,其角色要使用操纵杆(触摸板)移动。我使用Fit视口在保持迷宫的纵横比的同时将其保持在屏幕中央;
但是,我发现在迷宫旁边也添加了操纵杆。 sample of what it looks like currently
我希望操纵杆位于屏幕的左下角。我尝试对UI元素(包括操纵杆)使用不同的视口来执行此操作,但是整个迷宫只会变得失真。
这是我的BaseScreen类的一部分,该类也是我在其他游戏中重复使用的扩展:
public abstract class BaseScreen implements Screen, InputProcessor {
public BaseScreen(){
gameWorldHeight = 1024;
gameWorldWidth = 1024;
cam = new OrthographicCamera(gameWorldWidth, gameWorldHeight);
port = new FitViewport(cam.viewportWidth, cam.viewportHeight, cam);
port.apply();
cam.update();
mainStage = new Stage(port);
uiStage = new Stage(port);
uiTable = new Table();
uiTable.setFillParent(true);
uiStage.addActor(uiTable);
initialize();
}
public abstract void initialize();
public void render(float dt) {
mainStage.getCamera().update();
uiStage.getCamera().update();
uiStage.act(dt);
mainStage.act(dt);
update(dt);
mainStage.draw();
uiStage.draw();
}
public abstract void update(float dt);
public void resize(int width, int height) {
mainStage.getViewport().update(width,height, true);
uiStage.getViewport().update(width,height,false);
}
}
这也是我的GameScreen类的一部分,我实际上在其中编写了游戏的所有核心机制
public class gameScreen extends BaseScreen {
@Override
public void initialize() {
//..
uiTable.pad(10);
uiTable.add().expandX().expandY();
uiTable.row();
uiTable.add(ball.touchpad).left();
uiTable.add().expandX();
}
}
如果您想知道,这是ball.touchpad是
public class Ball extends BaseActor {
public Touchpad touchpad;
public Touchpad.TouchpadStyle touchpadStyle;
public Skin touchpadSkin;
public Drawable touchBackground;
public Drawable touchKnob;
public Ball (float x, float y, Stage s) {
//..
//Create a touchpad skin
touchpadSkin = new Skin();
//Set background image
touchpadSkin.add("touchBackground", new Texture("touchBackground.png"));
//Set knob image
touchpadSkin.add("touchKnob", new Texture("touchKnob.png"));
//Create TouchPad Style
touchpadStyle = new Touchpad.TouchpadStyle();
//Create Drawable's from TouchPad skin
touchBackground = touchpadSkin.getDrawable("touchBackground");
touchKnob = touchpadSkin.getDrawable("touchKnob");
//Apply the Drawables to the TouchPad Style
touchpadStyle.background = touchBackground;
touchpadStyle.knob = touchKnob;
//Create new TouchPad with the created style
touchpad = new Touchpad(10, touchpadStyle);
//setBounds(x,y,width,height)
touchpad.setBounds(15, 15, 200, 200);
}
那我如何在屏幕左下方添加此触摸板?
