如何移动游戏中网格的位置

Question

import pygame

pygame.init()

width = 800
height = 600
running = True
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Dijkstra's Path-Finding Algorithm Solver")
icon = pygame.image.load('icon.jpg')
pygame.display.set_icon(icon)

def title():
    button_font = pygame.font.Font('TrajanPro-Regular.otf', 40)
    rect_display = button_font.render('Dijkstra Path-Finding Algorithm', True, (255, 255, 255))
    # display global total deaths
    screen.blit(rect_display, (12, 10))

def title_underline():
    # create the button
    rect = pygame.Rect(0, 60, 800, 3)
    rect_display = pygame.draw.rect(screen, [255, 255, 255], rect)
    button_font = pygame.font.Font('TrajanPro-Regular.otf', 100)
    rect_display = button_font.render('', True, (255, 255, 255))
    # display global total deaths
    screen.blit(rect_display, (270, 198))

def grid():
    blockSize = 20 #Set the size of the grid block
    for x in range(width):
        for y in range(height):
            rect = pygame.Rect(x*blockSize, y*blockSize, blockSize, blockSize)
            pygame.draw.rect(screen, (200,200,200), rect, 1)

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    screen.fill((0, 0, 0))
    title()
    title_underline()
    grid()
    pygame.display.update()

我已经为我的项目创建了一个标题，我创建了一个网格，我想运行我的应用程序，但是网格是在我的屏幕上的每一个x，y位置创建的。但我希望网格只在标题下，而不是在上面。

定义网格的左上角坐标(grid_x，grid_y)，并在构造单元格的矩形时添加坐标。例如：

def grid():

    grid_x = 12
    grid_y = 30
 
    blockSize = 20 #Set the size of the grid block
    for x in range(width):
        for y in range(height):
            
            rect = pygame.Rect(
                grid_x + x*blockSize, grid_y + y*blockSize,
                blockSize, blockSize)
           
            pygame.draw.rect(screen, (200,200,200), rect, 1)
