At present, I am dividing certain objects into separate Portable Network Graphic (png) files to hand over to Brendan. These will include rollovers, menus, fridge objects etc. Above is a sample the clock states that will be animated during the course of each level. This image consists of nine separate png files. For our design we have created a stop frame animation from these images using the 'Sidewalk' excutable file accompanying Playground. It creates a single xml file and a single png file that can be controlled to correspond with gameplay.
