As you would expect, we need to create a new scene for our battles. There is a choice to make whether you want to create several scenes for different battle areas or define one generic scene and randomize the contents of that scene to add variation. Obviously there are pros and cons to each approach, but ultimately the choice is up to you.
For now, we will keep things simple and just create a new scene and then configure it as our battle area. So, add a new scene called Battle to the project and make it look pretty with some additional background scene elements.
For this example, I have used the Fantasy background (Environments\Fantasy\Background01.png) with some of the environmental assets from our asset pack to create the following screenshot:
