Question about using zones,

[Eagle]

I need to link a door to a new level so when a player touches a door or
opens a door he will be sent to a new zone that contains only the shop,
can someone tell me how?

I also wanted to know how to set an NPC to a certain location on the map,
like for instance, If I wanted to place a NPC in front of a door or by a
fountain how would I do that?

Thanks for all the help!

:D

always~
