我将如何编写代码，以便如果我按一次 ▲，图像从图像的当前位置向上移动 15 个空格，然后在大约 0.5 秒后向下移动 15 个空格?本质上，它是一个像马里奥一样的跳跃游戏，我会添加平台和其他东西.另外，我想知道如何确保您不能在空中进行双跳！对不起，我不是一个好的程序员，我只是需要这个游戏的帮助.
How would I make my code so that if I press ▲ once, the image moves up 15 spaces from the image's current position, and then goes down 15 spaces after about .5 seconds? Essentially, it is a jumping game like Mario that I will add platforms and other things to it. Also, I want to know how to make sure you can't double jump while in the air! Sorry that I am not a good programmer, I just need help for this game.
我使用的是 Python 2.7

添加 GRAVITY 常量，您可以将其添加到 y_change 每一帧以加速播放器向下.当玩家接触地面时，将 on_ground 变量设置为 True，当用户跳跃时检查他/他是否是 on_ground，然后将其设置为 False 防止双跳.
Add a GRAVITY constant which you add to the y_change each frame to accelerate the player downwards. When the player touches the ground set a on_ground variable to True and when the user jumps check if s/he's on_ground and then set it to False to prevent double jumps.
import pygame
pygame.init()
screen = pygame.display.set_mode((1000, 480))
clock = pygame.time.Clock()
GREEN = (110, 190, 27)
BLUE = (0, 185, 225)
PLAYER_IMG = pygame.Surface((30, 45))
PLAYER_IMG.fill((250, 120, 0))
GRAVITY = 1
def game_loop():
x = 1
y = 340
x_change = 0
y_change = 0
on_ground = True
ground_height = 400
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
return
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
x_change = -5
elif event.key == pygame.K_RIGHT:
x_change = 5
elif event.key == pygame.K_UP:
if on_ground:
# Set the y-velocity to a negative
# value to jump.
y_change = -20
on_ground = False
elif event.key == pygame.K_DOWN:
y_change = 5
elif event.type == pygame.KEYUP:
if event.key == pygame.K_LEFT and x_change < 0:
x_change = 0
elif event.key == pygame.K_RIGHT and x_change > 0:
x_change = 0
# Adjust the y-velocity by adding the gravity each frame.
y_change += GRAVITY
# Move the player.
x += x_change
y += y_change
# Stop the player on the ground.
if y > ground_height:
# Stop the movement along the y-axis.
y_change = 0
y = ground_height
on_ground = True
screen.fill(BLUE)
pygame.draw.rect(screen, GREEN, [0, 445, 1000, 35])
screen.blit(PLAYER_IMG, (x, y))
pygame.display.update()
clock.tick(60)
game_loop()
pygame.quit()
