[Help]What is A* (A Star)?

What is A* (A Star)?
Principle operation, simplification
Is there an example to combat?
I am still new to the newcomer.
I really want to understand the algorithm
But I don’t quite understand…

Hey Tony!

A* is a pathfinding algorithm based on nodes (also known as cells or tiles).
I haven’t used it much myself, but we do have a tutorial on the subject:


Note that that’s an iOS tutorial, but there’s hardly any code in there so the principles apply to Unity (& C#) as well.
I’m not sure what you mean by combat since the algorithm is used to find the shortest path from point A to point B on a given grid.

If you just need a quick solution for a game, you can also look into this excellent A* Pathfinding Project for Unity:

I did use that in the past and it’s easy to use and works pretty great once you set it up.

I hope that helps!
