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…

node?

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:

https://www.raywenderlich.com/4946/introduction-to-a-pathfinding

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!

Cheers
