Question

我正在使用PyGame创建游戏。

我想让我的角色看起来一直在运行。要做到这一点，我必须在两个精灵之间切换。但是这样做通常会导致图像变化太快，如果我添加

time.sleep(1)

暂停整个程序。如果这样做，则不允许我在暂停时间内输入任何内容。

import pygame
import time

pygame.init()


white = (255,255,255)
black = (0,0,0)
red = (255,0,0)
green = (0,155,0)


display_width = 500
display_height = 500



gameDisplay = pygame.display.set_mode((display_width, display_height))



pygame.display.set_caption("Sword")
gameDisplay.fill(white)

pygame.display.update()

sUp = pygame.image.load("C:/Users/michael/Google Drive/PyGame/Images/image4.png")
sUp = pygame.transform.scale(sUp, (500,500))
sUp1 = pygame.image.load("C:/Users/michael/Google Drive/PyGame/Images/image5.png")
sUp1 = pygame.transform.scale(sUp1, (500,500))
sDown = pygame.image.load("C:/Users/michael/Google Drive/PyGame/Images/image6.png")
sDown = pygame.transform.scale(sDown, (500,500))   


def SUP(x=0, y=0):
    gameDisplay.blit(sUp, (x, y))
    pygame.display.update()


def SDOWN(x=0, y=0):
    gameDisplay.blit(sDown, (x, y))
    pygame.display.update()

def running(x=0, y=0):
    gameDisplay.blit(sUp, (x, y))
    pygame.display.update()
    time.sleep(1)

    gameDisplay.blit(sUp1, (x, y))
    pygame.display.update()
    time.sleep(1)

def gameLoop():
    game = True

    while game == True:
        running()
        for event in pygame.event.get():
            print event

            if event.type == pygame.QUIT:
                game = False
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_SPACE:
                    SDOWN()

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_SPACE:
                    SUP()

    pygame.quit()
    quit()

gameLoop()

这是我的代码。如果有更好的方法，请告诉我。

由于

我已使用您的建议更新了它，但它返回了我在评论中提到的错误。我检查了代码，我很确定它是正确的。

frames = [sUp, sUp1] # Defined at the top of the code to define the frames 
frameid = 0 # The current frame
lastframe = None


def SUP(x=0, y=0):
    gameDisplay.blit(sUp, (x, y))
    pygame.display.update()


def SDOWN(x=0, y=0):
    gameDisplay.blit(sDown, (x, y))
    pygame.display.update()

def running(x=0, y=0):
    global frameid
    gameDisplay.blit(frames[frameid], (x, y))
    pygame.display.update()
    frameid = 1 if frameid == 0 else 0

def gameLoop():
    game = True
    lastframe = time.time()
    while game == True:
        if time.time() - lastframe() > 0.25: # Ensure we only update animation every 1/4 second
           running()
           lastframe = time.time()

        time = datetime.now()
        print time
        running()
        for event in pygame.event.get():
            print event

            if event.type == pygame.QUIT:
                game = False
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_SPACE:
                    SDOWN()

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_SPACE:
                    SUP()

    pygame.quit()
    quit()

    time.sleep(0.1)  # Run the game at 10 loops per second.
gameLoop()

我的部分意见......

在模块的顶部：

frames = [sup, sup1] # Defined at the top of the code to define the frames 
frameid = 0 # The current frame
lastframe = None

将运行功能更改为：

def running(x=0, y=0):
    global frameid
    gameDisplay.blit(frames[frameid], (x, y))
    pygame.display.update()
    frameid = 1 if frameid == 0 else 0

游戏循环函数中的

：

 lastframe = time.time()
 while game == True:
 if time.time() - lastframe > 0.25: # Ensure we only update animation every 1/4 second
       running()
       lastframe = time.time()

在循环结束时：

 time.sleep(0.1)  # Run the game at 10 loops per second.

这些都没有经过测试。

PyGame，我希望能够在不延迟整个程序的情况下延迟一些代码
