Hey there guys. I have come to a bit of a snag in my game. I am trying to make a Tales style of RPG where the player will essentially have 3 modes. A "Battle" mode, an "Exploration" mode, and a "Cutscene" mode. Since I have mostly been focusing on the games combat, I already have the "Battle" mode completed. The problem, however, is with the other modes.

What do you guys think the best way to execute this style would be? My goal is to have the player running around the world until he touches an "Enemy" entity. Once the entity is touched, the game then goes to the Battle Arena level, and once the player wins the game re loads the last position in the last world he was in. It's hard for me to describe, so here is a quick video demonstrating what I am talking about.

Demonstration

I currently have the "Main" script act as the test level for my combat system. Should I make three seperate scripts for all three modes? I was thinking of using a "Mode" variable. Something like this...

var mode = 0;

I am NOT asking for code or anything, merely advice on the best way to achieve this style. Thanks for your help guys, cheers.

Its a bit tough to say without knowing how you game "flow" is put together.
Not something that you could easily explain I think.

But as an idea, how does this sound.

Have three separate player "action"s and when the player shifts from
one game-mode to another, the currently running action calls the next
action type and then aborts itself.

EG.

(I first thought that video is your game, in wich case you dont need any advice

The cleanest way to have the different game modes, is
to have one main game-loop that acts as a state machine.

Depending on the case wich gamemode is running, the mainloop
executes the sub functions for each mode.
Any actions should observe if they are running in the
correct game-mode. If not, they should pause or delete the entity.

In case that your exploration and fighting area are different locations, you should use level-load to make a clean
new state for every fight / run-around.
All persistant data should not be stored in entity-skills,
but stored or saved to some global variables/fields.

After the level-load you can recreae the exploration-scene
from the stored data.
The fights usually dont need to save anything else than the
result to points and attributes.

The cuscenes could just pause the game and show the slides/video,
or when using the ingame-rendering, do the same as
the fights -> using a clean new level-load state.
