**Note:** Both point A and B are selected by the user from a list of locations in the building. I am making an app for school, and it is for new students in the school to find their way around as it is a big building. I am trying to brainstorm for ideas, the question is: ## How to get from point A to B, when point A or B can be any location that is specified in a list. The app must be able to look at the start point and end point, and work out a route. Each landmark as such would be a photo of a hallway, or room, etc. Is there a name for an algorithm for this that I could look into, or does anyone have any ideas? I can only think of separating the building into sections and making shorts lists specifying which sections to get from A to B. All help, if any, is much appreciated 🙂 ---

It’s called **pathfinding** but I’m no expert on it. ---

See [Here](https://buildasite.info/coding-challenge-51-1-a-pathfinding-algorithm-part-1/) This looks complicated but you can do it and share back when you figure it out!! ---

What a great site! The pathfinding section is really interesting: [https://www.redblobgames.com/pathfinding/tower-defense](https://www.redblobgames.com/pathfinding/tower-defense). And there’s also a section on hexagonal tiles which I did for a prior project. I ended up figuring them out on my own but that page would have helped a lot. ---
