Turned Based system?

Hey there, I’ve been interested in making an RPG with a turn based system. I was kinda wondering if someone would be able to point me in the right direction as to how I would go about a turned based system of fighting and the transition from one scene to the battle scene, and then back to the original point of contact with the battle, but with your hp decreased due to damage and items received. I haven’t really given it much thought cause I’m worried about the models and such, but if I could get a good point in a useful direction, that would be awesome, thanks a lot.

Examples would be like FFVII and Xenogears.

EDIT: Woops, just noticed I posted in the wrong board, ehh sorry, delete this is you so want to.
