Ok so far so good.
I can now have 2 actions per turn for a player. One is moving and one is “Building” although the build action is nothing more then placing a static mesh on the clicked index.
I am having a hard time wrapping my head around the build action |-_-|.
"Subtract the Z location of each tile to the Z location of the center tile and get the absolute value. If it is below an arbitrary threshold you want to add edges between the tiles (if there is not an edge there already). If it is above you want to remove the edges (if they exist).
To add and remove edges is simple. Use the RemoveTileEdgeBothWays and AddTileEdgeBothWays functions in BP_GridManager. There are already checks in place to make sure a tile is not added twice. For these functions input the grid index of the center tile and its neighbor. The order does not matter. You want to use the “both ways” function, as if you only add or remove one way you will still be able to move one of the directions."
Can you maybe elaborate this some more how I would stack the meshes and add a tile?
edit: Ok stacking of blocks works now. I forgot to name the Socketname to get the Z value of the mesh :D. Need to figure out now how to get up on the block.
