User Interface

This implements a camera class that allows the user to drag and zoom a virtual camera. It works basically by having child elements that are bigger than the view size of the given device. There isn't really a camera that moves, rather it just moves itself and any child elements relative to the devices normal view. Further, when the user lifts their finger in the middle of a drag, the drag movement will continue with some kinetic energy and slow down based on simulated friction.

Code example:

local camera = Camera.new()
local camera = Camera.new({maxZoom=1.5,friction=.5})
stage:addChild(camera)

-- Add whatever you want as a child of the camera
local image = Bitmap.new(Texture.new("sky_world_big.png"))
camera:addChild(image)
