Python Game Development Project Using OOP - Minesweeper Tutorial (w/ Tkinter) 

Wow, I am happy to see you on freeCodeCamp again, Jim

i recently watched some of your videos on your channel (python OOP videos) and i found some useful things. thanks!!

Thank you very much for your wonderful teachings.

Great course, Jim!

I have a question. I want to randomixe the mines if the first click is mine. How can I do that?

HAHA I did something similar, I left a section of commented lines called "IDBEHOLDA 😈"

Or randomize 1 mine instead of 9

how can I show all the mines at the game over?????????????????????????any one please, I tried this but it does not work def show_mine(self): for cell in Cell.all: if cell.is_mine: cell.cell_btn_object.configure(bg='yellow') ctypes.windll.user32.MessageBoxW(0, 'You clicked on a mine', 'Game Over', 0) sys.exit()

i created a button and bind it to the function. # Debugging mine_viewer = Button( left_frame, bg='black', fg= 'white', text= 'View Mines', font=('', 10), ) mine_viewer.place( x= utils.width_prct(2), y= utils.height_prct(25) ) mine_viewer.bind('', Cell.show_all_mines) #replace the Cell.show_all_mines() & add the above code to the main module. #just a nice touch. and great job on creating the function :)

and also changes on the real function @staticmethod def show_all_mines(event): mine_cell = [] for cell in Cell.all: if cell.is_mine: mine_cell.append(cell.cell_btn_object.configure(bg='yellow')) return mine_cell #added a list

Thank you. Could you also help with ctypes lib? windll doesn't work on Linux

@@to_my_ears haven’t tackled that part just yet. i saw there’s a way using gtk in linux, but I haven’t gotten it to work just yet

That issue makes me a little worried when developing cross-platform GUI apps. What GUI lib can be used cross-compile and using python?

Piggy-backing your comment to deliver another message to Linux users: as Jim mentions in the video, the ctypes module won't work for you. However, tkinter already has dialog box functionality. In `cell.py` add `messagebox` to this list of `tkinter` imports. Then, down in the `show_mine` method add: `messagebox.showinfo("title here", "message text here.")`

@@DennisChaves thank you! I'll definitely give this a try

Wonderful!

@anon only kotlin course is available.. There is an android studio course but they use Java in the course not kotlin... And they use xml not jet pack compose...Java and xml are old.. And nowadays people use kotlin and jet pack compose

Thx mate, could not figure out how to do that

@@dontreadmyusername6787 I meant making it myself will be even cooler

@@dontreadmyusername6787 no bro, you got it right, I miswrote. All good. Have a great day

Weird. Did you click the mine and the move cursor out of the cell? I noticed that my cells turned back to gray when I hover over them.

@@markomwansa I clicked on every cell, and it didn't change colour but showed that cell was being clicked and mines were opened randomly

same here

@@pearlr.2411 Aaah! Coding can be frustrasting lol. I would see if you have the same issue with the tutorial's code. The github link is provided up in the description.

If you're using mac, it handles buttons differently and won't let you change the background color. I got around it by highlighting the cell in the show_mine method instead: self.cell_btn_object.configure(highlightbackground="red")

if you're talking about all = [] then yes. it's a global variable. as the cell's are initializing, they are also getting appended in the list.

Pycharm

That's literally being unlucky lol

Typo in "hight=150"

There is only a min chance that ist will happen tree limes, so in this case I go with copy und paste

def left_click_actions(self,event): self.is_opened=True if self.is_mine: self.show_mine() else: self.cell_btn_object.configure(bg="SystemButtonFace") if self.surrounded_cells_mines_length==0: for cell_obj in self.surrounded_cells: if cell_obj.is_opened==False: cell_obj.left_click_actions('') cell_obj.show_cell() self.show_cell() if Cell.cell_count==settings.MINES_COUNT: ctypes.windll.user32.MessageBoxW(0,'You won!','Game Over',0) Note : I had to move the is_opened logic a bit and rewrite the Cell Left count. It's not terribly efficient but checks all of the cells for is_opened on each click. def show_cell(self): #if not self.is_opened: self.cell_btn_object.configure(text=self.surrounded_cells_mines_length) x=0 for celly in Cell.all: if celly.is_opened==True: x += 1 print(x) Cell.cell_count=settings.CELL_COUNT-x # Replace the text of the cell with a newer count if Cell.create_cell_count_label_object: Cell.create_cell_count_label_object.configure( text=f'Cells Left : {Cell.cell_count}' ) self.is_opened = True

Also trying to work this out. Have tried a recursive method that calls itself, but getting the same recursion depth error you're getting. Laurie's solution doesn't seem very efficient.

@@Sebastianimator You're most likely getting the recursion depth error because you check the surrounding cells on the clicked square, which checks the cells surrounding each of the cells surrounding the original cell including that original cell (amongst the other 8), which restarts the check again. Without a breaker you hit the native recursion limit. The cell count is affected by all of this virtual clicking. You can end up with a negative count unless you implement an alternate approach.

​@@ravag3 That's the intended functionality though. Logically, the method should first check if there's 0 mines, and if true, then loop through each surrounding cell that's not been opened, show it, then check if it's zero again. I'm not really following why the recursion depth would be a problem in this instance (though to be fair I haven't added any debugging to show how deep it's recurring).

because that's boolean value. None is totally different, False means something like 0 and true = 1

it's jut python's way of saying not opened, [ if self.is_opened not open ] ---> [ if not self.is_opened ]

Were you able to solve the problem? I have the same issue with the configure( bg ='orange')

I think it's because we have Mac OS System.

same

If you're using mac, it handles buttons differently and won't let you change the background color. I got around it by highlighting the cell in the show_mine method instead: self.cell_btn_object.configure(highlightbackground="red")

Here's my class and __init__. Note there are two underscores before and after init. These are called Dunder methods (double underscores). class Cell: def __init__(self, x, y, is_mine=False): self.is_mine = is_mine self.cell_btn_object = None self.x = x self.y = y

@@BlitheBrandon thank you, but i already have my code like this i dont know what happen

@@BlitheBrandon maybe you have other idea :s

@@efhndz7990 paste class line and your __init__ method, like I did. I'll take a look.

@@BlitheBrandon class Cell: def __int__(self,x,y,is_mine=False): self.is_mine=is_mine self.cell_btn_object=None self.x=x self.y=y

try `exit(0)` with out the sys. it'll still work and the 0 is exit code for the parent process to know the program is terminated.

I am using mac for this project

@@soumobratamanna6681 I'm also working on a Mac in my create_btn_object method, I have these binds and they are working for left and right clicks. btn.bind("", self.left_click_actions) btn.bind("", self.right_click_actions)

@@BlitheBrandon Only the left button is working , I am follwoing the same thing like the way u said but still it's not working , after clicking right button its showing that I am left clicked .

pls fix my error

@@soumobratamanna6681 share your btn.bind lines here.

You don't mention what specific problems you've encountered, but I'm going to go out on a limb and point a finger at the dot between the f and the initial double quote. It should look like: f"{self.x}, {self.y}"

PyCharm

it's in the description of the video
