Unity's AI Navigation or Aron's A* Pathfinding Project for a top-down 2D game?

Hi there!

I’ve just finished setting up my first map (with obstacles) for my top-down 2D project and I’m exploring enemy navigation/AI options. I’m currently deciding between two packages: Unity’s AI Navigation and A* Pathfinding Project.

My requirements are relatively simple:

  • Agents need to perform basic actions (move, wander, patrol, chase)
  • Movement should be restricted to 90-degree turns (similar to Bomberman or Tank games)

While A* Pathfinding Project seems capable of handling these requirements, I’m wondering if Unity’s AI Navigation can accomplish the same tasks? I’m naturally leaning towards Unity’s solution due to its larger community support, but I’ve seen some comments suggesting it can be problematic with grid-based movement.

Has anyone had experience with either package for similar grid-based movement requirements?

Thanks!
