[英]Full screen background regardless of screen size and keep image aspect ratio
我有一個 540x720 的背景圖片。
無論屏幕大小和分辨率如何(我的游戲將在桌面和 Android 上運行),無論縱向/橫向模式如何,我都需要以全屏方式顯示它。
如有必要,我想通過裁剪圖像來保持圖像的縱橫比。
我已經嘗試過 ScreenViewport 和 ExtendViewport,但是在調整窗口大小時,背景不再是全屏(例如,如果窗口變為水平)並且出現信箱(顯示白色邊欄)。
public class MainMenuScreen implements Screen, InputProcessor {
final MyGame game;
TextureRegionDrawable textureRegionDrawableBackground = new TextureRegionDrawable(new TextureRegion(new Texture(game.backgroundFileName)));
Stage stageBackground = new Stage(new ScreenViewport());
// Stage stageBackground = new Stage(new ExtendViewport(Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), new OrthographicCamera(Gdx.graphics.getWidth(), Gdx.graphics.getHeight())));
Image image = new Image(textureRegionDrawableBackground);
image.setPosition(0, 0);
image.setHeight(Gdx.graphics.getHeight());
// makes the background as tall as the screen while maintaining its aspect ratio
image.setWidth(Gdx.graphics.getHeight() * textureRegionDrawableBackground.getRegion().getRegionWidth() / textureRegionDrawableBackground.getRegion().getRegionHeight());
stageBackground.addActor(image);
}
public void render(float delta) {
stageBackground.getViewport().apply();
stageBackground.draw();
}
public void resize(int width, int height) {
stageBackground.getViewport().update(width, height, true);
}
如何做到這一點?
謝謝
使用FillViewport
,它將通過裁剪圖像的一部分來保持縱橫比並全屏顯示。
