Can ProGrids be used in game?

Is it possible to use ProGrids in game?

I've been developing a movement system for my game that allows the player move objects on a grid, however I would like to use something more robust and came across ProGrids.

 

progrids doesn't really do anything except for allow you to visualize units and snap objects by increment. you can achieve this yourself. i suggest you research the A* algorithm and pathfinding in general as it will help you to understand grids in a less abstract way. Try to visualize a plane that takes up one single tile with it's origin directly in the center. A grid is just a combination of these objects. You can make your own grid system. There's a bunch of youtube tutorials on A* to help you familiarize yourself with the concept. You don't have to actually use it for pathfinding if you don;t want to, but even just the concepts should help you.
