Is it possible to get real world coordinates and use it to trigger event in game?

Hi! I’m really new to this but I want to try something. Please bear with me

My project is a mobile game (Android). So, I want to know is it possible to

  • Set zone with real-world coordinates (with LocationService I guess?)
  • Set a trigger so when player devices are in that zone, it’ll trigger event in the game

Thank you in Advance! Any suggestions would be appreciated.

Sure, Pokemon Go was made with Unity.
