Grid Framework is a powerful, yet easy to use solution for all your grid-based needs. Just drag a grid component of your choice onto an object in your scene, set the values to your liking and get started making your game without worrying about the underlying math. All grids are three-dimensional, support rotation and are infinite in size. Convert coordinates from world space to grid space and back, render it, find vertices, faces and boxes, align and scale objects to your grid or store vertices inside a matrix for quick access.
No matter if you are making a board game, a strategy game, a puzzle game, an arcade-style game or just any other type of game that needs clockwork-like precision, Grid Framework will help you in setting up your game and writing game logic in an intuitive way.
