Hello,

Can anyone help me to overcome this issue, I can post the full code if required

Kind regards

Stewart.

ObjectGrid2D is shown correctly within the GUI.
I use the same code for a horizontal rectangle and a vertical rectangle with the following differences:

Grid Width and Grid Height are reversed.
Random start X and start Y

Here is the neighbourhood function I use and the function to get the next cell.
hop = dist.

  mySpace.getMooreNeighbors(myX, myY, hop, Grid2D.BOUNDED, false, result, xNeighbors, yNeighbors);

  nextX = mySpace.tx(xNeighbors.get(i));
  nextY = mySpace.tx(yNeighbors.get(i));
  if (mySpace.field[nextX][nextY]== null) {
      mySpace.field[nextX][nextY] = child;
      child.myX = nextX;
      child.myY = nextY;
      theAgents.add(child);
      counter++;
      break;
     }
   } myX = nextX; myY = nextY;
 }


Horizontal works correctly at all times and Vertical always gives an incorrect Y position at the start.
Also Y coordinate does not go beyond the X coordinate size. Thus we see a square area occupied equivalent of X squared.

Regardless of the grid sizes the same behaviour is observed. In addition when I use the same code for the von Neumann Neighbourhood the same errors are observed.

"mySpace.getVonNeumannNeighbors(myX, myY, hop, Grid2D.BOUNDED, false, result, xNeighbors, yNeighbors);"

This is the output obtained for the Moore neighbourhood:

Horizontal rectangle. Initiate and one step.

 GridWidth = 10, GridHeight = 5.
 Start X = 3, Start Y = 3.
 x = 2 : y = 2
 x = 2 : y = 3
 x = 2 : y = 4
 x = 3 : y = 2
 x = 4 : y = 4
 x = 3 : y = 4
 x = 4 : y = 2
 x = 4 : y = 3
 nextX = 2 : NextY =  : 2
 
Vertical rectangle. Initiate and one step.

 GridWidth = 5, GridHeight = 10.
 Start X = 2, Start Y = 8
 x = 1 : y = 7
 x = 1 : y = 8
 x = 1 : y = 9
 x = 2 : y = 7
 x = 3 : y = 9
 x = 2 : y = 9
 x = 3 : y = 7
 x = 3 : y = 8
 nextX = 1 : NextY = 2

Vertical rectangle. Second step.
This is correct.

 Start X = 1, Start Y = 2
 x = 0 : y = 1
 x = 0 : y = 2
 x = 0 : y = 3
 x = 1 : y = 1
 x = 2 : y = 3
 x = 1 : y = 3
 x = 2 : y = 1
 x = 2 : y = 2
 nextX = 0 : NextY = 1
