Spawn more items/place items with a trigger

For example, on an enemy death, it would be nice to be able to spawn hearts, triangles, a key (looking forward to that whole system being implemented)...
Also, place/manipulate other items with a trigger, like spawning some pottery shards when you break a vase, and/or, make the barrels and vases actually interactive (breakable).
