JRPG battle transitions

Having trouble with something simple and can’t seem to find a tutorial for it. When i run into an enemy, i want the screen to switch to a “battle map” and then respawn the player and the enemy on that map.
Some reason I can not get this to work. I am rather new. I have a “fader” already that happens between scenes but I can’t get the battle transition right.

Also should I use an entirely new scene for it, or simply make another terrain hidden from the first, and have them respawn there?

Separate scenes are always a worthwhile win in Unity.

Also, breaking your game into “sub scenes” (loaded additively) is also a win: then you can unload certain scenes and keep others, then load new ones and so on.

For instance, I often have a single GameManager scene, then it additively loads a Player scene, then a UI scene, and whatever Content scene I’m on (level 1, level 2, etc.)

Finally when the game is over I go to a new GameOver scene, then back to Menu.

Scenes are awesome in Unity.

I recommend getting the overall flow first, with instant-transitions, then it’s fairly easy to drop in fader effects after the fact, and by not having them initially you avoid confusing the process.
