//Usage: PingPongInit(%obj, %marker, %time, %smoothness, %delay)
//
//%obj = Object to move
//%marker = Destination position marker
//%time = time in milliseconds for one half of the ping-pong
//%smoothness = Number of movement updates per second, more = smoother = more CPU taxing.
//%delay = time delay in ms at each end of the path

), like for instance the clouds, lets say I wanted to put, I don't know a bird and I wanted it to move here and there and show up like a certain number of times, and actually make it look like its flying, would that be possible?
