In this Unity tutorial, we'll explore how to add some simple obstacle resolution logic to enemies, so they don’t get stuck walking into each other.
We’ll also look at how the same logic can be used to have the enemies navigate around obstacles.
To do this we'll make use of Unity's Physics2D.CircleCast method to detect obstacles and then take action to avoid them
This is the twentieth video in our series showing how to make a full top down 2D shooter game in Unity.
