```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;
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
