  • height - The height of the grid (number of cells in the y-direction).

Methods

private void initialiseGrid()

• Description: Initialises the grid by creating a GridCell at each position.

public GridCell getCell(int x, int y)

• Description: Gets the GridCell at the specified coordinates.
• Parameters:
  • x - x-coordinate of the cell.
  • y - y-coordinate of the cell.

public boolean isOccupied(int x, int y)

• Description: Checks if the cell at the specified coordinates is occupied.
• Parameters:
  • x - x-coordinate of the cell.
  • y - y-coordinate of the cell.

public void setOccupied(int x, int y, boolean occupied)

• Description: Sets the occupancy status of the cell at the specified coordinates.
• Parameters:
  • x - x-coordinate of the cell.
  • y - y-coordinate of the cell.
