X/Y Moving

[SabreKnot]

Is there anyway I could make something so that if the player touchs the npc, they will move left or right slowly until they reach the X coordinate and then move up/down until they reach the Y coordinate?

I want it to be able to be done anywhere on screen and still end up in the same place. Its for a chapel level, it is long, so I want to make it so when a person sits down, an npc of them is put in their place and they are made invisible... they slowly move to the X and then to the Y so that they can be sitting in the ver back, yet can see the main part of the level. Also, when they say "back" it needs to put them back in the place and get rid of the npc.

I dunno if it can be done, im more of an LAT than an NAT so I need help lots lol.
