我是libgdx的新手,并且一直在练习使用ShapeRenderer
。我试图在屏幕底部放置一个矩形,但是Gdx.graphics.getHeight()
函数返回的值不能覆盖整个长度。如果我将矩形的坐标设置为(0, screenHeight)
,则它只会在屏幕上移一半。
此外,当我记录getWidth()
和getHeight()
函数的尺寸值时,它们都返回1440。
width = getWidth()
和height = getHeight()
时的This is the rectangle (White section)。
代码:
public class GameClass extends ApplicationAdapter {
private SpriteBatch batch;
private Texture goalTexture;
private Sprite sprite;
private OrthographicCamera cam;
private ShapeRenderer shape;
private ScreenViewport viewport;
//x-axis length for top/bottom bar
private float goalWidth = 200;
//y-axis height for back bar
private float goalHeight;
private float goalPostThickness = 20;
//Screen height and width
private float screenWidth;
private float screenHeight;
//How far down/up posts are from edge of screen
private float goalPostOffset;
@Override
public void create() {
viewport = new ScreenViewport();
cam = new OrthographicCamera();
cam.setToOrtho(false, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
shape = new ShapeRenderer();
}
@Override
public void dispose() {
batch.dispose();
goalTexture.dispose();
shape.dispose();
}
@Override
public void render() {
//Logic
screenWidth = Gdx.graphics.getWidth();
screenHeight = Gdx.graphics.getWidth();
System.out.println(screenWidth);
System.out.println(screenHeight);
goalPostOffset = screenHeight/3;
//Draw
cam.update();
Gdx.gl.glClearColor(0, 0, 0, 0);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
shape.setProjectionMatrix(cam.combined);
//Top goal bar
shape.setColor(Color.WHITE);
shape.begin(ShapeRenderer.ShapeType.Filled);
shape.rect(0, 0, screenWidth, screenHeight);
shape.end();
}
@Override
public void resize(int width, int height) {
}
@Override
public void pause() {
}
@Override
public void resume() {
}
}
答案 0 :(得分:3)
您在代码部分张贴的是错字。您在高度中加载宽度 screenHeight = Gdx.graphics.getWidth();
