Battle On Map

[MasterMind]

I would like it if someone quickly made me a script to make it so when a battle starts, instead of teleporting to the battlescreen, it teleports the player to a designated map instead. I should be able to tag which map it teleports the player to somehow. It should look like this:

Spoiler: Battle Screen from Selwyn's Era Eilel ourobos

See how the battle is taking place on a map? That's what I would like. If there's already a script for this, please direct to me to it. Thanks in advance.
