Welcome to GTGD S2 LEARN UNITY 2D, a brand new tutorial series relaunched for Unity 2021! In this series I'll be showing my approach to using the Unity 2D tilemap dynamically so that in game the player can place and remove tiles, and for the navmesh to update dynamically, and of course saving and loading that data to file and managing multiple save files. You will develop a day and night system and write AI that will respond to the time of day! What you learn in this series will be beneficial in many different projects especially for understanding how to save and load data to file and manage multiple save files.
