Well, I think the way you're trying to do it is alot more complex then it has to be. Since this isn't exactly a script request, I'm not going to make it for you.
But to create an event with scripts is kind of more trouble than its worth when you could just use RPG Maker itself to right-click and create one. Anyways, to create an event all you have to do is this:
event = RPG::Event.new(x, y) # Your x and y
And there you have a blank event! But, you want to have a certain graphic, so you then have to do:
event.page.graphic.character_name = "" # You graphic name
event.page.graphic.direction = 2 # Direction
event.page.graphic.pattern = 0 # Pattern
And THEN you have to add what you want the event to do, which is just a pain in the ass... and then you have to get it on the map by adding it to Game_Map. I'm sure someone will cover the rest if you need it. (But I suggest that you find an easier way to do what you have in mind.)
