RMXP Getting Started

Ive just started to use RMXP (Rpg maker xp) and ime not sure how to use it.
But all i know is the basics. so could someone help me

Is there anything in particular you're looking for help with, such as variables or switches, or is there something you want to do, but can't seem to get to work?

well let me think, i need to know how to make the interior of houses and haw to get a good battle system and enimies.
I think thats about it. And ime not sure how to use switches

I'll let someone else cover the battle system and enemies. And I can link you to a number of threads about switches sometime.

Interiors.

How familiar are you with creating new maps, and teleporting the player to the new maps?

i know how to make new maps and how to teleport

That's basically it.

If you make the interior of the house as a new map, say 50 x 50, or even smaller, and put a teleport to it in the door of the exterior on the village map, then you'e got it all working.

If you go into the properties of each map, then you should be able to set a chipset to each map - that is, the different elements you can use. So if you don't like the default chipset, you can easily find an interior using a Google search and use that instead.
