Question

import pygame

#intialize the pygame
pygame.init()

# create the screen
screen = pygame.display.set_mode((800,600))
# Title and Icon
pygame.display.set_caption("Space Invader")
icon = pygame.image.load('spaceship (1).png')
pygame.display.set_icon(icon)

# Player
playerImg = pygame.image.load('ship.png.png')
playerX = 400
playerY = 490

def player(x,y):
    screen.blit(playerImg, (x, y))

# game Loop
running = True
while running:
    # RGB - Red, Green, Blue
    screen.fill((0, 0, 0))
    playerX += .1

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    player(playerX, playerY)
    pygame.display.update()

说

"DeprecationWarning: an integer is required (got type float). 不推荐使用 int 隐式转换为整数，可能会在 Python 的未来版本中删除。 screen.blit(playerImg, (x, y))"< /p>

警告与blit()的坐标参数有关。浮点坐标意味着 Surface 的原点介于窗口中的像素之间。那没有多大意义。坐标会自动隐式截断，并由警告指示。
使用 int 或 round 将浮点坐标转换为整数：

def player(x,y):
    screen.blit(playerStand, (round(x), round(y)))

我试图找出将playerX移到屏幕上的问题是什么？我想移动playerX + = .1，但出现错误？
