Examples for realtime moving or hiding of props?

Hi everyone,

I'm new to Unity and even more new to programming in general. I'm hoping to find good tutorials or example files specifically for the following situation.

I've created an interior of an apartment and props like furnature. I want to have a series of possible positions stored for each prop, and want to allow the player to be able to choose from these positions for each prop via a keypres or a UI.

For instance, the player might select the sofa, and each time the player clicks on the sofa Icon it would dissappear from its current spot and appear at the next predetermined spot in the interior.

Ideally I'd like these positions (the ones selected) to be stored as variables that are fetched from a MySQL database

Anyone run across this sort of example?

thanks for your time.
