我试图在我的游戏中制作一个日光循环,但是一旦变成晚上就不会回到白天

I tried to make a daylight cycle in my game, but once it turns to night it will not go back to day

对于我的游戏中的另一个错误,日光循环将不起作用我尝试翻转位置: 时间 = 0 去,但运气不好,我调查了这个问题,我只找到了为其他语言制作 day/night 的方法,而当我尝试通过其他方式自动将其更改为 day 时,python 不喜欢它。

正如我所描述的,我尝试翻转位置:

Time = 0

进入:

elif Time >= 4800:
    Time = 0
    Raycast('Textures/Screens/Skybox/Earth',0,0,800,600)
    ReDisplayItem()

但运气不好,我什至尝试使用 while 语句,但 python 不喜欢那样。

import pygame

#2000,1001

pygame.init()

Screen = "None"

Sobj = "None"

Width = 800

Height = 600

Time = 0

Frame = pygame.display.set_mode((Width,Height))

pygame.display.set_caption("HypoPixel")

FPS = pygame.time.Clock()

def ReDisplayItem():
    if Sobj == "None":
    Raycast('Textures/Extra/ItemBox.png',0,0,160,160)
elif Sobj == "Loom":
    Raycast('Textures/Extra/IBO.png',0,0,160,160)
    Raycast('Textures/Blocks/loom_side.png',10,10,140,140)

def Raycast(TTR, RayXPos, RayYPos, RaySizeX, RaySizeY):
    RaycastThis = pygame.image.load(TTR)
    RaycastThis = pygame.transform.scale(RaycastThis,(RaySizeX,RaySizeY))
    Frame.blit(RaycastThis, (RayXPos, RayYPos))
Loop = True
Raycast('Textures/Screens/Skybox/Earth.png',0,0,800,600)
Raycast('Textures/Extra/ItemBox.png',0,0,160,160)
while Loop == True:
    Time = Time + 1
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            exit()
        if event.type == pygame.KEYDOWN:
            if event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
                exit()
            elif event.type == pygame.KEYDOWN and event.key == pygame.K_0:
                Raycast('Textures/Extra/ItemBox.png',0,0,160,160)
                Sobj = "None"
            elif event.type == pygame.KEYDOWN and event.key == pygame.K_1:
                Raycast('Textures/Blocks/loom_side.png',10,10,140,140)
                Sobj = "Loom"
    if Time >= 2400:
        Raycast('Textures/Screens/Skybox/EarthNight.png',0,0,800,600)
        ReDisplayItem()
    elif Time >= 4800:
        Time = 0
        Raycast('Textures/Screens/Skybox/Earth',0,0,800,600)
        ReDisplayItem()
    pygame.display.update()

FPS.tick(60) 

本以为是黑夜转白昼,没想到天黑了。

当条件Time >= 4800满足时,那么Time >= 2400也满足。

永远不会执行elif语句中的语句列表,因为if条件在"wins"之前计算。

所以 if 条件必须是 Time >= 2400 and Time < 4800:

if Time >= 2400 and Time < 4800:
    Raycast('Textures/Screens/Skybox/EarthNight.png',0,0,800,600)
    ReDisplayItem()
elif Time >= 4800:
    Time = 0
    Raycast('Textures/Screens/Skybox/Earth',0,0,800,600)
    ReDisplayItem()

或者情况的顺序必须颠倒:

if Time >= 4800:
    Time = 0
    Raycast('Textures/Screens/Skybox/Earth',0,0,800,600)
    ReDisplayItem()
elif Time >= 2400:
    Raycast('Textures/Screens/Skybox/EarthNight.png',0,0,800,600)
    ReDisplayItem()
