Its main function is the computation of action grids: queriable grids that efficiently store all pathing and attack options available to a unit during its current turn. Square tiles and hexagonal tiles are supported, but line of sight is not yet implemented for hex tiles.Action grids are intended to be used for efficiently retrieving shortest paths to any reachable tile, for displaying the movement and attack options that are available to the player's selected unit, and for providing AI units with a search function to retrieve the set or a subset of valid actions, which can then be processed by your high level AI controller.The system includes features such as editing of level layouts in the editor and at run-time, multiple terrain types with different interaction per unit and optional line of sight checking when determining which tiles are in attack range. Action grids can be merged to represent the influence radius of multiple units. An example map and player controller is included that demonstrates usage of the plugin in blueprints and handling of player input. All blueprint is commented.A detailed user guide for this plugin is available at: http://www.zkshao.com/downloads/TBStrategyGrids_UserGuide.pdf
