QUESTION
I wrote a pretty simple minesweeper clone using tkinter, but for some reason when I call the boom()
method, "BOOM!"
is printed but the window is not closed. Why is this not working?
ANSWER
Answered 2021-Jun-09 at 03:43You never called boom
function. That's the issue.
QUESTION
Trying my hands on a beginner minesweeper project and have a question on nested loops. I understand the basic when its with numbers. However, adding arrays and objects into a nested loop iteration is a bit tricky for mind and need some clarity (understanding the logic better).
For the below code, does the "const row = []
" reset back to an empty array after every time the inner loop finishes pushing the "tile" variable into "row"? I am assuming it does since X will go to "1", which it'll reset the loop again?
Declaring boardSize as 2, I got an output of:
board First Iteration: [[{0,0}, {0,1}]]
board Second Iteration: [[{0,0}, {0,1}],[{1,0},{1,1}]]
ANSWER
Answered 2021-Jun-05 at 19:59Yes you are correct, const row is declared in a Scope, which is terminated after the iteration is finished, each iteration will have it's own row variable. Generally a new scope is created if the code is surrounded by Curly Braces {}
such as If statements, Functions, and Loops, though there are a few extra cases.
The Lowest Scope will override scopes Above it, and variables Defined within a scope are only accessible to that scope and other scopes within it.
QUESTION
I'm learning wxWidgets and am trying to make minesweeper using wxButton
s. I use the following code to create and position the buttons:
ANSWER
Answered 2021-Jun-01 at 16:20To make the grid sizer layout the buttons, you need to either
- set it to be the sizer for a window or
- add it to another sizer.
Assuming the code above is from the constructor of your main frame window, you would set grid to be the sizer for the frame like this
QUESTION
Clicking on one of the tiles triggers clickerbox().
The issue is that if the user clicks on a tile with b no surrounding mines it's supposed to reveal them, and if any of those also have no mines it should do the same.
It seems to do some of this and then stop before revealing all the tiles it should. I was wondering if anyone knew why or how to fix this?
screenshot of the game board after a zero is clicked on
The first 5 clicks were made by the user then the rest where triggered by the function.
...ANSWER
Answered 2021-May-29 at 23:30The mistake is hidden in for
loop of autoclick
function:
for (i = 0; i < 8; i++) { ... }
You have to use var
keyword to create local iteration variable. Otherwise the global variable is created and reused by recursive calls.
for (var i = 0; i < 8; i++) { ... }
My favorite game btw.

I am Currently working on a minesweeper algorithm for a cs50 assignment. There seems to be an issue with my code. (Inside the minesweeper class)

...ANSWER
Answered 2021-May-23 at 19:56During the iteration over safes
(the cells
of a Sentence
) you call self.mark_safe(safe)
. That removes the cell
in cells
on which you iter. But you cannot change a set during iteration.
Grab a shallow copy of safes
and iterate over it instead.
QUESTION
Recently I've been trying to learn C++ through SFML. The Project I'm working on at the moment is Minesweeper (https://minesweeper.online/ if not familiar with the game). I want to avoid having to attach too much code so I'll explain step by step what the program does and elaborate on parts that run into issues.
- A
Grid
object is created, containing two 2D arrays,grid
andstategrid
. populate()
populatesgrid
with a certain amount of randomly placed mines, in this case 1 mine, for simplicity's sake.- the
analyze()
function fills in the amount of surrounding mines per tile. - the
check()
function checks if the mines are not too clumped together, if so, it repeats steps two and three.
An important thing to notice is that the stategrid
array stores wether a tile has been 'discovered' or not. Another is that 'discovering' these tiles needs to be done recursively, as when you discover empty tiles, you must maneuver around corners and into cavities. The way I set this up is that when you 'open up' a specific tile with the dig()
function and adjacent tiles are empty, these are opened aswell. The reason why this SO error surprised me is that I have set the condition that if a tile had been opened before, it could not be opened again as to avoid looping indefinitely, causing such an error.
Any help with this would be greatly appreciated.
PS: If this snippet of code is incomplete or additional information is required, please let me know.
PPS: It's quite late already where I live, so this could just be the result of late-night-blindness to details ;)
...ANSWER
Answered 2021-May-02 at 11:42Turns out my grid was too big considering i only had one mine, so there were too many empty squares and recursion went too deep. With more mines/smaller grid the program worked fine.
QUESTION
I am a beginner at python and decided to attempt to make minesweeper. Everything seems to be working correctly, but the section of my code responsible for filling a dictionary with data on every square does not seem to be working. here is the function in question:
...ANSWER
Answered 2021-Apr-24 at 20:51You should put parenthesis i.e. (int_to_str(x, y) in grid_values) == False
or better yet you should write it as int_to_str(x, y) not in grid_values
.
When you're writing it as you did, it's operator chaining. Meaning, int_to_str(x, y) in grid_values == False
is equivalent to int_to_str(x, y) in grid_values and grid_values == False
.
QUESTION
I was trying a very simple thing with javascript, to create a minesweeper grid.
...ANSWER
Answered 2021-Apr-22 at 13:05The issues is that Array#fill
doesn't do what you think it does.
In your example you create a SINGLE array Array(gridsize).fill(null)
and then you put that array at each index of the outer array. Meaning that your grid
actually contains the same array, 9 times over. So when you assign grid[0][0]
you actually assign grid[0][0]
, grid[1][0]
, grid[2][0]
, grid[3][0]
, etc... all at once (ish).
