Scratch

Hey, I can't figure out how to create an RPG with a map, that displayed your, lets say arrow, in the correct position. I also need to know how to make a big area. for example if you went through this pathway you'd go here but then if you took a left, the background would change to the costume that correspondes to the persons movements...do you follow me? So if anyone knows a project/thread or can help that would be really helpful! Oh and I would be sure to give credit!
