    Lines actually place mines in the requisite number of randon locations on the board by setting the appropriate cells in the mines array to true. You can play the game just like Microsoft's Minesweeper. Recursion may be slower, but it doesn't matter for small inputs and you almost never have to uncover more than 20 fields This simple explanation hides some potentially quite complex behaviour from this method. However, markng a cell does reduce the count of mines remaining displayed beneath the board, so you can see at a glance how many more mines there are to be found.

    For example my recursive method in my MineSweeper implementation is:. static void main(String[] args) { Minesweeper ms = new Minesweeper(LENGTH. You're creating an infinite loop, since each cell will recur to every neighboring cell, and then each of those that is empty will recur back to the.

    Actually, Worakarn: Minesweeper does not check 4 corners. This protection is important, because we do not want other classes -- perhaps written by other people -- manipulating the internal state of the board in undefined or illegal ways.

    You should probably not attempt to work through this whole set of notes in one sitting; it might be best instead to just read the material for one class and make sure you have fully understood this before moving on to the next. By this point, the player has located all of the mines on the board except for those in the cluster of cells on the left hand side.

    At the end of the game the program will reveal all of the mines whether marked by the player or not and indicate the time taken to play this game. Should you reveal a mine, the game is over and you have lost.

    The StringTokenizer will automatically convert the strings it reads into numeric values, where this is possible.

    The next five methods simply return various items of information about the board, such as its width and height, or the number of cells still unknown. The protected declaration is ideal for this purpose.

    The two nested loops in lines simply set the entire board to a known state: all cells are unknown and no cells at this point contain mines. The parser can recognise and respond accordingly to any string that is in its language; any input that is unrecognised will be rejected.

    open gamefield using recursion */. This is my code for inspecting a cell in minesweeper, and it is not working as I had expected but I can't quite figure out what is wrong.

    But recursion shortens the code and makes it as simple as possible. Like for As mentioned in my first blog, I'll be writing the code in Java.

    String input = s.
    We will rejoin the game a few dozen moves later:. For the class to be truly reusable, it must be carefully designed to make sure that all of the necessary functionality is made available to both current and potential future users of the class. If the cell thus revealed has no neighbouring mines ie.

You should probably not attempt to work through this whole set of notes in one sitting; it might be best instead to just read the material for one class and make sure you have fully understood this before moving on to the next.

    It also opens up any number fields next to zero fields as in ms minesweeper.

    You have to add a check if the cell is already disabled right after checking if x and y are within the bounds and if so return, otherwise you are creating an infinite loop.

    Line 33 creates a new StreamTokenizer object that will read commands from System. You will need to read up on Java's graphics and interface toolkit classes, and restructure the program somewhat this one is very difficult!

    That is, Board will be invoked as the first action of the TextClass constructor. Obviously the version using the conditional operator is much more compact, but it could be argued that the if statement is easier to read.

    1. If insufficient parameters were given, the program prints a brief message telling the user how to run the program correctly, then exits.

    2. In this case the conditional operator was used because four almost-identical if statements would have made the method about five times as long, perhaps obscuring the half-dozen lines at the end of the method that do the actual work!

    3. Right click for marking the mine slots The clicked button will be green and left click for opening the slots. What the Board class will not do is provide any user interface, nor impose any fixed set of rules on the game.

    4. Otherwise, the convert the three parameters to their integer equivalents, create a new MineSweeper object and call its play method to start the game. If we know that all of the column number strings are say three characters long, we know that they will occupy three rows of the terminal when printed in vertical orientation.

    5. By implementing the board in this way, we leave the way open to provide any user interface and set of rules that we care to, while ensuring that the Board class itself is reusable and does not have to be changed for each new variation of the game that we create. Suffice it to say that it will eventually get the job done, provided that the number of mines does not exceed the number of cells on the board!
