Provides 1D, 2D, and 3D grids, including rectangular and hexagonal, configurable in the editor. Features advanced shape transformations, A* pathfinding, range-finding, and other grid algorithms.

Render pipeline compatibility

The Built-in Render Pipeline is Unity’s default render pipeline. It is a general-purpose render pipeline that has limited options for customization. The Universal Render Pipeline (URP) is a Scriptable Render Pipeline that is quick and easy to customize, and lets you create optimized graphics across a wide range of platforms. The High Definition Render Pipeline (HDRP) is a Scriptable Render Pipeline that lets you create cutting-edge, high-fidelity graphics on high-end platforms.

Description

Grids are used in strategy games, RPG games, puzzle games, and many more. If you need a grid in your game, this package is for you.

Suitable for a variety of games

Supports 1D, 2D, and 3D grids.
Supports rectangular and hexagonal grids.
Provides sophisticated ways to describe grid shapes. Besides using several primitive shapes, you can also combine shapes or transform shapes using a variety of operators.

Suitable for implementing gamelogic and algorithms

Allows grids to be used as data structures similar to 2D arrays or dictionaries, which may or may not have a physical representation in the game. This makes it easy to keep your logic and representation separate.
Provides useful games-specific grid algorithms: A* path finding, range finding, connected sets (includes connected line algorithms used in match games), and 2D aggregation (can be used to diffuse AI knowledge of game state over time).
Provides integer vectors (grid points) and matrices, so linear transformations can be done efficiently in grid spaces. This allows you to work with grids geometrically in ways similar to using floating point vectors and matrices.

Provides editor setup

Allows you to build grid shapes from graphs in the editor.
Allows you to build grid maps from graphs in the editor. (This technology allows you to do things such as put a hex grid on a ring or Mobius band).

Advanced Usage

Comes with algorithms to calculate grid colorings: systematic ways to classify cells into patterns that are useful in many grid algorithms.
Can be extended to support more exotic grids, additional shape nodes or additional map nodes.
