Activating Monsters/Entities

[GhastDagger]

Hey guys, i need a couple of monsters and a corpse to appear after the player picks up an item, and make a Vase break when the player gets near it, and also the scare effect (the 1 that makes the camera get pushed or somethin) plus making him look at a direction for a couple of seconds

Would you kindly tell me the scripts and callbacks i'll need to make these things ? also is it possible to make a window break after the player picks the item ?

sorry for asking too much..
