center
fun Camera.center(width: Float = Gdx.graphics.width.toFloat(), height: Float = Gdx.graphics.height.toFloat(), x: Float = 0.0f, y: Float = 0.0f)
Centers this Camera in the middle of the given rectangle. width and height represent the size of the rectangle in world (camera/viewport) units. x and y are optional offsets in world units that will modify camera position.
Note that Camera.update should be called in order to update to the new position.
fun BitmapFont.center(text: String, width: Float, height: Float, x: Float = 0.0f, y: Float = 0.0f): Vector2
Calculates center position of the chosen text written with this BitmapFont on an object with given width and height drawn at x and y coordinates.
The passed text rendered with the selected BitmapFont at the returned coordinates should be in the middle of the object.
Note that x and y are essentially an optional offset added to the calculated position.
