为何pygame显示器无法正常播放？

问题描述

我正在尝试使用Pygame在Python中创建基于图块的2d平台游戏。我从创建窗口和瓷砖系统开始。它引用一个文本文件，并根据在该文件中找到的每个数字，将图像复制到Pygame显示窗口（草图像为“ 2”，污垢图像为“ 1”）。执行程序时，磁贴会出现在屏幕上，但会快速闪烁并缓慢移动到一侧。瓷砖之间也有缝隙，我不确定为什么要在其中，但我想摆脱它们。

import pygame,sys
pygame.init()

dirt_img = pygame.image.load("dirt2.png")                  #loads dirt image
dirt_img = pygame.transform.scale(dirt_img,(80,80))       #scales dirt image up to 80*80

grass_img = pygame.image.load("grass2.png")                #loads grass image
grass_img = pygame.transform.scale(grass_img,80))     #scales grass image up to 80*80

clock = pygame.time.Clock()                              

window = pygame.display.set_mode((1200,800))


#load map
def load_map(path):
    f = open(path + '.txt','r')             #open text file
    data = f.read()                         #reads it
    f.close()                               #closes
    data = data.split('\n')                 #splits the data by the new line character

    game_map = []                           #creates game map data
    for row in data:
        game_map.append(list(row))          #ads each line in'map.txt'..
                                            #..data to new game map list
    return game_map

game_map = load_map('map')

grass_count = 0         #meant to be used to count each time a grass tile is blitted to.. 
                        #..move the position over 80 pixles for the next tile to be blited  
dirt_count = 0          # I think this might be where my problem is but I am not sure.


# Main loop

run = True
while run:
        
    for event in pygame.event.get():
            if event.type == pygame.QUIT:
                    pygame.quit()
                    sys.exit()
                    
    window.fill((135,178,255))             #sets light Blue background color

    for layer in game_map:
                for tile in layer:                                            
                    if tile == '1':                                         #finds '1' in file,dirt_count += 1                                     #updates dirt count,window.blit(dirt_img,(100 * dirt_count + 80,500))#blits next dirt tile
                    if tile == '2':                                         #finds '2' in file,grass_count += 1                                   #updates grass count,window.blit(grass_img,(100 * grass_count + 80,500))#blits next tile
                                
                   
    clock.tick(60)

    pygame.display.update()

pygame.quit()

解决方法

变量dirt_count和grass_count递增，但是它们永远不会变回0。将变量设置为0，就在循环之前：grass_count = 0 grass_count = 0。无论如何，我认为这不会满足您的需求，因为磁贴的坐标似乎并不取决于其索引。

图块的位置很可能取决于row和column：

for row,layer in enumerate(game_map):
    for column,tile in enumerate(layer):
        x,y = 80 + column * 100,80 + row * 100
        if tile == '1':
            window.blit(dirt_img,(x,y))
        if tile == '2':
            window.blit(grass_img,y))
