Map Graph v1.1.2 is now available. This update mostly addresses some issues with the Randomly Stamp Tilemaps node and hexagonal grids. Please be aware that the Randomly Stamp Tilemaps node now gives a different output on the Placements port, so that may affected your existing map generators. In order to get the same result as before, you can merge the result from the Placements port and Empty points port together, using the newly added Merge Points node. Changes: Made changes to how the Randomly Stamp Tilemaps node stamps tilemaps. It no longer stamps the empty tiles within the tilemap prefab's bounding rectangle, removing any existing tiles at those points. Please note: This change might impact your existing Map Graphs' output, as these empty tiles are no longer included in the points gotten from the Placements output port. Instead you can now get them from the new Empty Points port. Added the Empty Points output port to the Randomly Stamp Tilemaps node, containing any empty tiles spaces within the stamped tilemap prefab's bounding rectangle. Added the "Create/Map Graph/Tilemap Prefab" option to the Create menu, which creates a new tilemap prefab with all the required components, as a more convenient way of creating entries for Tilemap Sets. Added the Map Graph Tilemap Prefab component with a Lock Shape option for tilemap prefabs with hexagonal grids. Enabling Lock Shape on a tilemap prefab will make adjustments to tile coordinates when it's stamped onto another tilemap, so that its shape stays the same whether it's placed on rows with different offsets or not. More info about this issue in this forum post: https://forum.unity.com/threads/rel...ed-random-map-generation.944568/#post-6681352 Added the optional "Precise Margin?" input port to the Randomly Stamp Tilemaps node. Settings this to true will create a more accurate margin outline around stamped tilemaps, instead of the default bounding rectangle, at the expense of performance. Added the Merge Points node, which takes two sets of points and merges them together into one set. Check out the complete changelog here.
