I found/made some sprites for a "pipe"type game. A pipe game is like trying to direct water through pipes to get to a certain area. My question is, what would be the most efficient way to check if the pipes are connected? Link to a game with the same concept. thanx in advance and if know one knows, i understand.

Oh, but i don't need the water "flow" effect, just want to know how i can check if they are connected.

if collision left side?

Make an array, or give each pipe section sensors on all four sides that tell what is around them.
