Need help to create a custom event

Thank you Gi Nattak, those tutorials are good and I already studied them. I'll explain the steps I do and I'll have many questions to ask lol


1-Should i do b2 and go to the f1 bank or should I start my event at the end of the intro?
Then 6B (BA) BA= the old man crazy house inside. So now I have to position de character.
2-How do I know where to place theme?
3-How can I change the map(erase table, add thing)
