  • Yes, chess group will do the job.

  • Update:

    New plugin: rex_board_edge , to maintain edges on a board.

    User also need to update rex_board, rex_slg_movement plugin.

    Done.

  • Update:

    rex_board plugin: add action: create chess above tile

    rex_board_edge plugin: add condition:On edge kicked

    I will add more actions/conditions to make the board system more easy to use.

  • rexrainbow, thanks so much for pointing me here! I still have to try to implement the board_edge plugin, but it looks very promising.

  • Hi again rexrainbow,

    I've been trying to implement the board_edge plugin, and so far, for a certain configuration, it works.

    However, when using squareTx's '8 direction' the edge only respects one direction. I've attached an image which demonstrates the behaviour: the player is behind a long wall, and if the target tile is behind the wall, it will try to move diagonally (because there is no edge between the diagonal tiles). If I use '4 direction' it works fine.

    I've tried switching squareTx.Direction based on slg_movement's PreTile and Tile conditions, but I can't get it to work and I'm not sure if this is correct approach.

    I'm still trying to play around with the switching, but you have any tricks/ideas to get around this, it would be much appreciated.

    Thanks again!

    best,

    lernie.

    You are right, it had miss something in my board system in squareTx layout.

    In squareTx's '8 direction' mode, the grid will become an octangle, although it looks like a tetragon. So that it will have 8 edges, you need put a "wall" for diagonal side, currently.

    I will try to solve it. Let me think....

    [Edit]

    You might try to turn the direction mode to 4 direction before requesting a path in slg_movement plugin.

  • Hi rexrainbow,

    Thanks for the suggestion. I've used 4 direction successfully, but I am currently trying to find a way to combine it: using 4 direction when it hits an edge, and 8 direction when no edge is involved.

    I'm trying to find a logic solution, but it would be nice to get your thoughts on it because you're obviously more familiar with the moving path algorithm.

    What I will attempt is this:

    -request a moving path from slg_movement

    -move chess accordingly

    -for every GridMove On tile, determine if current tile has an edge

    -if current tile has edge, switch to 4 direction

    -then get rid of moving path

    -request another moving path from current position to original destination

    (That's just the rough idea)

    (I will, of course, update if I get anything working)

    Thanks again!

    "using 4 direction when it hits an edge, and 8 direction when no edge is involved."

    • "Condition:Has edges around chess" and set parameter direction to (-1) to check if there is any edge around TileUID.
    • "Expression:NeigborUID2DIR" (new in board plugin, you need update board plugin) to get the direction from PreTileUID to TileUID.

    In 4 directions, the value is 0~3, in 8 directions, the value is 0~7.

    It might be -

    + NOT Edge :Has edges around chess : TileUID , dir to (-1) // no edge around TileUID

    • set cost to 1

    + ELSE

    + Board.NeigborUID2DIR( PreTileUID , TileUID ) >= 4 // diagonal

    • set cost to BLOCKING

    + ELSE

    + Edge :Has edge between chess ( PreTileUID , TileUID )

    • set cost to BLOCKING

    + ELSE

    • set cost to 1
  • Hi rexrainbow, I've updated the latest on GitHub, but the NeighborUID2DIR expression doesn't seem to be registered in the editor (need to update edittime.js, too?). Thanks!

  • faulknermano

    Yes, you need download these files. Or using this tool to update my plugins.

  • Thanks rexrainbow! Your download tool updated it, and now I can see the NeighborUID2DIR expression.

    However, just so you know your GitHub repository doesn't seem to be updated; I compared the new edittime.js with the one in my GitHub directory (which I'm always synching), and NeighborUID2DIR only appears in the tool-updated one, not in GitHub.

    Thanks again.

  • faulknermano

    I might forget submit the code, sorry.

  • rexrainbow, thanks for your help. I finally got it working! The first few times I tried to make it work, the function became messy. But during the debugging I started to understand how slg_movement's moving path function worked, and I came up with something more straightforward, and something that I could read and maintain later.

    Like you suggested, Board.NeighborUID2DIR was used to get 'check direction', used a 2-dim array to get the 'reverse direction', corner1 (left of direction), and corner2 (right of direction).

    Then I made 2 checks: first check is destination Tile; if an edge exists the 'reverse direction', or any of the reverse direction 'corners', it means tile is inaccessible: movement is blocked (cost = -1).

    Second check is PreTile: if edge exists in the 'check direction' of PreTile, or any of the check direction corners, then movement is blocked.

    Else, default variable cost value of 1 is used.

    Again, thanks for this suite of plugins you've made. Although at the beginning it was hard to use because I didn't quite understand how it worked 'under the hood', now that I have more experience with it, it is getting easier to tweak and get specific results, making it a powerful tool.

  • faulknermano

    Congratulations!

    Your request is too specific to implement in a simple way. It really need dig the board system more deeply, to get more information from board/edge.

    For tracing, you could dump PreTileUID and TileUID to console, under "on cost" event. Anyway, I am glad that you had came up this problem.

    "on cost" could be customized to do diffusing, see the demo in this post.

    Have fun!
