Have and Idea, Need Help

[PhZXgames]

I have an idea, but I need help to bring it to life. (through Ren'py)

I want to make a moving sequence Like in the Pokemon Franchise, you have a little overworld sprite and you move around on a grid template of the world. Is that possible? I'm sure it is somehow, like displaying an image that automatically centers itself as the character moves around. Now that I think about it, it'd basically be like moving a picture, but having a small sprite in the middle.

Also another question would be doors and/or exits. Pokemon used a portal system, like when the player's sprite hit a certain tile (or tiles) then it would plop them down on another map. How would I go about doing this? Let me know if any of you geniuses out there can explain it to me.

Thanks!
