    to those asking implement entrance/ exit to the maze you can garb all the outer walls as such
    //if x=0 first row get the leftwall
    //if x==row-1 last row get the rytwall
    //if z=0 first colunm get the backwall
    //if z=cols-1 first colunm get the frontkwall
    add them to a list an perhaps find an index and clear 2 walls for entrance n exit
    x,and z being the index of the cell row and colums being the width and the depth as per this tutorial

      You can basically put both at opposite ends because every tile can be reached from everywhere

  • @weckar
    @weckar Před rokem +3

    This is nice. However, this method tends to create a single long main path with relatively short side branches.
    To prevent that, you can iterate over a shuffled queue of all cells with unvisited neighbors instead.
    In addition; at the end of the process, you can knock down a couple extra walls at random to create loops and overall a less straightforward to solve maze.

If you know what I mean?

    Never mind I got it.
    For anyone who wants to know:
    Create a variable inside your mazecell script to store the number of active walls of that cell. Now in the maze generator script fetch all the cells who have only 3 active walls, as dead end cells are the only cells with 3 active walls.

    Wow! Sweet stuff! Unity is awesome 🎉 would be nice to add code to the script to create a second floor. So, when the algorithm stops. It's time to move to second floor but there needs to be a connection to the floor below. Stairs or ladders! Then when you set y= 0 just make it y = 1. I will try it out

    • @KetraGames
      @KetraGames  Před rokem +1

      Hi, this is because when using Instantiate it sets World position rather than the local position. You can fix this by adding the following line
      _mazeGrid[x, z] = Instantiate(_mazeCellPrefab, new Vector3(x, 0, z), Quaternion.identity, _parent);
      _mazeGrid[x, z].transform.localPosition = new Vector3(x, 0, z);
      You'll also need to use local position further down in the algorithm
      private IEnumerable GetUnvisitedCells(MazeCell currentCell)
      {
      int x = (int)currentCell.transform.localPosition.x;
      int z = (int)currentCell.transform.localPosition.z;
      Hopefully this should get it working 😊
