Tool Model Change while hold it. how to ?

Hi. Thanks to read my topic now. I have a problem major for creating my game (Tears of Another's Life)

And i need to creat an item named (The Finder) its an Eye.. notting really special. but! this object is suposed to help the player to find hidding object (or hidden way)

i've think abouth 3 option.. but i dont have enought skills with scripting to do what i need to.

1- Make the eye look at a specific point to gide the player 2- Change the model of the eye

and 3 .. only put sparkle on it (i prefer not this one)

Hope somebody help me that should be really apreciated.

Hey BTW i can send some money to someone who really want to help me (only by your email Safe and secure)

i really need to finish this game and the only think it stop me is the scripting so. i offert 5 Dollard by script if its simple and 15 if its more loud I pay first
