用于天气系统的Python Pygame Random Imgs

标签: python python-3.x random pygame

我10岁的儿子正试图在这个2D游戏中实现一个天气系统的新功能,他使用pygame进行教程,但遇到了IdententationError问题。

我一直在帮助他,但我还在学习,我认为这是随机和显示,但我不知道如何解决它,因为这是他的第一个pygame方法之一。

他试图让它产生随机天气以在屏幕上发送。他还希望在线下添加碰撞检测,但他仍然在学习该主题。

这是他的代码: all files我还包括原始完成的未完整编辑的

问题区域1:

获取IdententationError第259行就是这个

randomNumber = random.randint(0,20)

从这里下来4行

#a list of resources
WEATHER = [CLOUD,RAIN,THUNDER,TORNADO]

#loop through each weather type and choose weather type for it to be
        #pick a random number between 0 and 20
        randomNumber = random.randint(0,20)
        #if a zero, then the weather is TORNADO
        if randomNumber == 0:
            WEATHER = TORNADO
        #water if the random number is a 1 or a 2
        elif randomNumber in [1,2]:
            WEATHER = THUNDER
        elif randomNumber in [3,4,5,6,7,8]:
            WEATHER = RAIN
        else:
            WEATHER = CLOUD

问题区域2:

#display the weather
DISPLAYSURF.blit(textures[WEATHER].convert_alpha(),(weatherx,weathery))
#move the cloud to the left slightly
weatherx+=1
#if the weather has moved past the map
if weatherx > MAPWIDTH*TILESIZE:
    #pick a new position to place the weather
    weathery = random.randint(0,(MAPHEIGHT*TILESIZE) - 150)
    weatherx = -200

以下是他尝试添加天气之前的原始云系统

#commented out the original cloud only weather system 
#display the cloud
DISPLAYSURF.blit(textures[CLOUD].convert_alpha(),(cloudx,cloudy))
#move the cloud to the left slightly
cloudx+=1
if the cloud has moved past the map
if cloudx > MAPWIDTH*TILESIZE:
    #pick a new position to place the cloud
    cloudy = random.randint(0,(MAPHEIGHT*TILESIZE) - 150)
    cloudx = -200

守则的其他部分

但不是下面的完整代码我们认为是正确的

我在pygame中导入并随机设置时钟

import pygame, sys, random
from pygame.locals import *

fpsClock = pygame.time.Clock()

我加载了天气关闭屏幕

#weather position
weatherx = -200
weathery = 0

天气类型的选择,我可以在雪下等地方添加更多信息

   #the number of each weather type that we have
weather =   {
                CLOUD    : 0,
                RAIN     : 0,
                THUNDER  : 0,
                TORNADO  : 0
                         }

这是我添加纹理或png图像的方法,我遗漏了许多其他图像

DIRT    : pygame.image.load('C:\\Users\\Daddy\\Documents\\python\\working_34\\mincraft2d\\dirt.png'),

有些时候为了让它工作,我必须显示如上所述的完整路径

    #a dictionary linking resources to textures
    textures =   {
                    DIRT    : pygame.image.load('dirt.png'),
                    GRASS   : pygame.image.load('grass.png'),
....

                    CLOUD   : pygame.image.load('cloud.png'),
                    RAIN    : pygame.image.load('rain.png'),
                    THUNDER : pygame.image.load('thunder.png'),
                    TORNADO : pygame.image.load('tornado.png')
             }

我在第261行收到错误,如果randomNumber == 0,则以开头:

    #pick a random number between 0 and 20
    randomNumber = random.randint(0,20)
    #if a zero, then the weather is TORNADO
    if randomNumber == 0:
        WEATHER = TORNADO
    #water if the random number is a 1 or a 2
    elif randomNumber in [1,2]:
        WEATHER = THUNDER
    elif randomNumber in [3,4,5,6,7,8]:
        WEATHER = RAIN
    else:
        WEATHER = CLOUD

1 个答案:

答案 0 :(得分:1)

以下是代码对我来说的样子..(对于第一个问题,第259行)。

    #a list of resources
WEATHER = [CLOUD,RAIN,THUNDER,TORNADO]  # <-- problem here.

    #loop through each weather type and choose weather type for it to be
    #pick a random number between 0 and 20
    randomNumber = random.randint(0,20)
        #if a zero, then the weather is TORNADO
        if yada yada ...

你需要缩小从WEATHER开始的行或者从开始randomNumber的行开始。缩进在python中用于代码块。 WEATHER和randomNumber行之间没有任何内容(如if语句或while语句),这意味着randomNumber行应该相对于WEATHER行缩进。与你得到的所有其他缩进问题相同。在randomNumber分配之后的if行有类似的问题。除非有理由不(例如if语句的主体,而不是if语句本身),否则使用相同的缩进深度获取所有行。

要清楚..它应该是什么样的(所有缩进的4个空格):

    #a list of resources
    WEATHER = [CLOUD,RAIN,THUNDER,TORNADO]  

    #loop through each weather type and choose weather type for it to be
    #pick a random number between 0 and 20
    randomNumber = random.randint(0,20)
    #if a zero, then the weather is TORNADO
    if yada yada ...

也很好,你花时间和你的孩子一起做这件事。
