A ProximityGrid<T> is a uniform 2d grid that can efficiently retrieve items near a specified grid cell. C BVTree: A tree of bounding volumes. C Node: The data stored in a bounding volume node. C CompareX: An IComparer<T> implementation that only compares two Nodes on the X axis. C CompareY
Unity Grid component and adaptation for pathfinding I recently discovered that 2D Tilemap package in 2019.4 LTS comes with a Grid component. I did some experiments and found out that I can potentially make use of this Grid system for AI navigation in the game.
Penalties and tags are more flexible with this package than what Unity has. I think raw pathfinding in this package is faster (I am not 100% sure though), among other things because I think Unity only has the option to use a single thread for pathfinding while this package can use any number of threads.

5. Non-square Search Areas: In our example, we used a simple 2D square layout. You don't need to use this approach. You could use irregularly shaped areas. Think of the board game Risk, and the countries in that game. You could devise a pathfinding scenario for a game like that.
List<PathFind.Point> path = PathFind.Pathfinding.FindPath(grid, _from, _to); If you don't care about price of tiles (eg tiles can only be walkable or blocking), you can also pass a 2d array of booleans when creating the grid "Unity 2d Pathfinding" and other potentially trademarked words, copyrighted...
Learn how to make a 2D Roguelike game with this project. Over the course of the project you will create procedural tile-based levels, implement turn-based movement, add a hunger system, and finally add audio and mobile touch controls. This video series was filmed in Unity 5, but is compatible with Unity 4.6 as well. Want to learn more about this topic? Connect with a community expert for a 1:1 ...

The A* pathfinding project is quite powerful, and allows multiple grid graphs out of the box, which is quite handy considering the requirements of to use the "getting started" movement code instead of anything fancy. code is from here: How to setup the A* Pathfinding Project in a 2D Unity environment.
