The overworld is no different than any other level. The main difference is that most classic JRPGs use a free camera as opposed to fixed camera.

You can create the OverworldCamera from the Level Design Tool

The other main difference is how the transition from OW to other levels work. Usually for the OW we will use a CrossSceneDoor. This means a new level will be loaded and the OW unloaded.

Going from a level to the OW

To go to an overworld level, simply use a Cross-Scene Doors

You can find an example of this type of door in GameExample, where the door transition will unload the current level to load the OW level

Going to a level from the OW

These are also implemented as cross scene doors. But in our GameExampleOverworld it’s implemented slightly different.

The Door is triggered from an interaction, so the player will see an interaction prompt (an exclamation over the player’s head) and won’t trigger automatically like other doors.

However, you can choose the approach that works best for your project.
