Row Count and coloumn count

[Yegor123]

Im making my first game on python and it was talking about adding row and coloumn counts could someone explain what that means and what does it do ?

You will need to provide more information. The question is kinda vague.

So im watching this video on a tile game and he said everytime i go through one of the tiles increase that variable by one and I didnt really Understand what he was talking about. Ive also never used this type of code before so I dont understand it. here is my code for reference

row_count = 0
        for row in data: 
            col_count = 0
            for tile in row:
                if tile == 1:
                    img = pygame.transform.scale(dirt_img, (tile_size, tile_size)) 
                    img_rect = img.get_rect()
                    img_rect.x = col_count * tile_size
                    img_rect.y = row_count * tile_size
                    tile = (img, img_rect) 
                    self.tile_list.append(tile)              
                col_count += 1
            row_count += 1

world_data = [
[ 1 ,1 ,1, 1, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,1 ,1, 1, 1],
]

world_data can be thought of as a grid, like a chessboard. "tile" is used to refer to the individual squares. A row is a group of tiles aligned in one direction, and a column is a group of tiles aligned in the other direction (often horizontal rows and vertical columns).

For your example:

world_data = [
[ 1 ,1 ,1, 1, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,0, 0, 0, 1],
[ 1 ,1 ,1, 1, 1],
]

The first row is:

[ 1 ,1 ,1, 1, 1]

and the first column is

[ 1,
  1,
  1,
  1,
  1 ],

The way world_data is organized, it is very easy to loop through the rows, because each row is a list.

row[0] = [ 1 ,1 ,1, 1, 1]
row[1] = [ 1 ,0, 0, 0, 1]
row[2] = [ 1 ,0, 0, 0, 1]
row[3] = [ 1 ,0, 0, 0, 1]
row[4] = [ 1 ,1 ,1, 1, 1],

The "for row in data:" loop will run 5 times, once for each row shown above. The first time through the loop it uses row[0], the second time through the loop it uses row[1]. This continues until the last loop uses row[4].

"for tile in row:" works just like "for row in data", except this time it loops through the values in row. If row == row[1]:

tile[0] = 1
tile[1] = 0
tile[2] = 0
tile[3] = 0
tile[4] = 1
