Example 26 with SpriteBatch

use of com.badlogic.gdx.graphics.g2d.SpriteBatch in project libgdx by libgdx.

the class TideMapDirectLoaderTest method create.

@Override
public void create() {
    float w = Gdx.graphics.getWidth();
    float h = Gdx.graphics.getHeight();

Example 27 with SpriteBatch

use of com.badlogic.gdx.graphics.g2d.SpriteBatch in project libgdx by libgdx.

the class Box2DTest method create.

@Override
public void create() {
    // setup the camera. In Box2D we operate on a
    // meter scale, pixels won't do it. So we use
    // an orthographic camera with a viewport of
    // 48 meters in width and 32 meters in height.
    // We also position the camera so that it
    // looks at (0,16) (that's where the middle of the
    // screen will be located).
    camera = new OrthographicCamera(48, 32);
    camera.position.set(0, 15, 0);
    // create the debug renderer
    renderer = new Box2DDebugRenderer();
    // create the world
    world = new World(new Vector2(0, -10), true);
    // we also need an invisible zero size ground body
    // to which we can connect the mouse joint
    BodyDef bodyDef = new BodyDef();
