Python 如何在pygame中反映屏幕 我想从右边画出矩形

如何使这些矩形水平移动？ 我试图从本教程中理解它，但我无法理解 有什么想法吗 我的小角色幽灵

导入pygame

pygame.init（）
显示宽度=800
显示高度=600
gameDisplay=pygame.display.set_模式（（800600））
pygame.display.set_标题（'FullMarx'）

def重影（x，y）：
游戏显示.blit（鬼影，（x，y））
定义事物（thingx、thingy、thingw、thingh、颜色）：
pygame.draw.rect（游戏显示，颜色，[thingx，thingy，thingw，thingh]）
def text_对象（文本、字体）：
textSurface=font.render（文本，真，黑色）
返回textSurface，textSurface.get_rect（）

text rect.center=（（显示宽度/2），（显示高度/2））
blit（TextSurf，TextRect）
def gameOver（）：
信息显示（“游戏结束”）
def rect（）：
pygame.draw.rect（屏幕、颜色、（x、y、宽度、高度）、厚度）
def事件（）：
对于pygame.event.get（）中的事件：
如果event.type==QUIT或（event.type==KEYDOWN和event.key==K_ESCAPE）：
pygame.quit（）
sys.exit（）

尽管如此：

#____鬼魂运动___________#
keys=pygame.key.get_pressed（）
如果不是（isJump）：
如果键[pygame.K_UP]或键[pygame.K_SPACE]或键[pygame.K_w]：
isJump=True
步行次数=0
其他：
如果跳线计数>=-9：
负=1
如果跳线计数<0：
负=-1
y-=（跳线计数**2）*0.5*负
跳转计数-=1
其他：
isJump=False
跳数=9
时钟滴答（50）
#____鬼魂运动
#东西（东西，东西，东西，东西，东西，颜色）
事物（事物开始，事物开始，事物宽度，事物高度，黑色）
物体开始速度+=物体速度
幽灵（x，y）
如果事物开始>显示高度：
物体起点=0-物体高度
thing\u startx=random.randrange（0，显示宽度）
如果y<物体起点+物体高度：
打印（'y交叉'）
如果x>thing\u startx和xthing\u startx和x+ghost\u width

通过修改矩形的x和y坐标来移动矩形（从而移动播放器/图像）

下面是一个基本的注释示例，可帮助您可视化：

import pygame
from pygame.locals import *


# Initialize a screen
SCREEN = pygame.display.set_mode((700, 500))
# Fill it with black
SCREEN.fill((0, 0, 0))

# Create a rect that'll represent our player
# Arguments: x, y, width, height
player = pygame.rect.Rect(100, 100, 20, 50)



# Keep track of which direction
# the player is moving in
moving_left = False
moving_right = False
moving_up = False
moving_down = False


# Loop
while True:
    for event in pygame.event.get():
        # Go through every event that pygame
        # records, the 'event queue' and
        # react accordingly

        # User closed the window
        if event.type == QUIT:
            pygame.quit()


        # If the user presses any key, a
        # KEYDOWN event is placed into the
        # event queue, and we detect it here
        if event.type == KEYDOWN:

            if event.key == K_d:
                moving_right = True

        # pressing the keyboard,

            if event.key == K_s:
                moving_down = False


    # Increment/decrement the players
    # coordinates, its 'position'
    # this is akin to movement
    if moving_left:
        player.x -= 2
    if moving_right:
        player.x += 2
    if moving_up:
        player.y -= 2
    if moving_down:
        player.y += 2


    # Repaint our screen black,
    SCREEN.fill((0, 0, 0))

    # draw our player (the rect)
    # onto the SCREEN, at its coordinates
    # in white.
    # You'd simply use SCREEN.blit
    # here in order to place an image
    pygame.draw.rect(
        SCREEN, (255, 255, 255),
        player
    )

    # refresh the screen to show our changes
    pygame.display.update()

你必须对2D表面上的运动进行概念化，如下所示：

不要在帖子中添加垃圾。必须将

东西\u startx

位置设置为大于屏幕宽度的值，并在每一帧中从中减去速度。
