Minesweeper

Welcome to this tutorial on building your very own Minesweeper game using the LÖVE framework and Lua programming language. Minesweeper is a classic puzzle game that challenges players to clear a grid of hidden mines using logic and deduction. By the end of this tutorial, you will have a fully functional Minesweeper game and a deeper understanding of game development concepts.

In this step-by-step guide, we will cover everything from setting up your development environment to implementing game mechanics such as grid creation, bomb placement, and user interactions. Whether you are a beginner or an experienced developer, this tutorial will provide you with the knowledge and skills needed to create a fun and engaging game.

Let’s dive in and start building our Minesweeper game!

Grid Creation

In this section, we will start by creating our Minesweeper grid. The grid is the main playing field where the game takes place. It consists of a matrix of cells, each of which can either contain a mine or be empty. We will use a two-dimensional array to represent this grid in our code.

Here is a step-by-step guide to creating the grid:

Initialize the Grid: First, we need to initialize the grid with empty cells. We will create a function to generate a grid of a specified size.

function createGrid(rows, cols)
   local grid = {}
   for i = 1, rows do
      grid[i] = {}
      for j = 1, cols do
        grid[i][j] = { isMine = false, isRevealed = false, isFlagged = false, adjacentMines = 0 }
      end
   end
   return grid
end

Next we will create a function to draw the grid infomation into our canvas

function update()
  -- draw grid
  for row = 1, MINE_ROWS do
    for col = 1, MINE_COLS do
      drawGrid(row, col) -- we will create a function to draw a grid on row,col
      drawMines(row, col) -- draw an exploded mine
      drawUnopenedBox(row, col) -- we will create a function to draw an unopened mine
      drawOpenedBox(row, col) -- show the number of mines on its surounding
      drawFlagged(row, col) -- if not opened an the user choose to flag the box as mine, we will display a little flag
    end
  end
end

2. **Place Mines**:
Next, we will randomly place mines in the grid. We will create a function to place a specified number of mines.

```lua
function placeMines(grid, numMines)
   local rows = #grid
   local cols = #grid[1]
   local placedMines = 0

   while placedMines < numMines do
      local row = math.random(1, rows)
      local col = math.random(1, cols)
      if not grid[row][col].isMine then
        grid[row][col].isMine = true
        placedMines = placedMines + 1
      end
   end
end

Calculate Adjacent Mines: After placing the mines, we need to calculate the number of adjacent mines for each cell. This information is crucial for the player to make informed decisions.

function calculateAdjacentMines(grid)
   local rows = #grid
   local cols = #grid[1]

   for i = 1, rows do
      for j = 1, cols do
        if not grid[i][j].isMine then
           local count = 0
           for x = -1, 1 do
              for y = -1, 1 do
                local ni = i + x
                local nj = j + y
                if ni > 0 and ni <= rows and nj > 0 and nj <= cols and grid[ni][nj].isMine then
                   count = count + 1
                end
              end
           end
           grid[i][j].adjacentMines = count
        end
      end
   end
end

Putting It All Together: Finally, we will create a function to initialize the entire grid, place the mines, and calculate the adjacent mines.

function initializeGame(rows, cols, numMines)
   local grid = createGrid(rows, cols)
   placeMines(grid, numMines)
   calculateAdjacentMines(grid)
   return grid
end

By following these steps, we have successfully created the grid for our Minesweeper game. In the next sections, we will implement the game mechanics such as revealing cells, placing flags, and handling win/loss conditions.
