Does anyone have any idea of how to achieve an effect like Piperoll here - http://www.youtube.com/watch?v=Gqzrt6Ks8_Y
I'm guessing a grid with series of sprites that can be rotated 4 ways, but not sure how you would do the following:
1) Detect whether a connection has been made?
2) If connection has been made then how do you mask the water so it progresses through the pipe?
Many thanks for your help
