出现错误 需要解密整数

Question

我一直在按照本教程使用 pygame 构建一个简单的 2D 游戏。 我已经多次检查了我的代码，但我仍然无法弄清楚这个错误意味着什么

import pygame as pygame  
pygame.init() 
window = pygame.display.set_mode((500, 500))
pygame.display.set_caption('First Game')
pygame.display.update()

在这里，我设置了所有命令以响应用户的输入

walkRight = [pygame.image.load('R1.png'), pygame.image.load('R2.png'), pygame.image.load('R3.png'),
pygame.image.load('R4.png'), pygame.image.load('R5.png'), pygame.image.load('R6.png'),
pygame.image.load('R7.png'), pygame.image.load('R8.png'), pygame.image.load('R9.png')]
walkLeft = [pygame.image.load('L1.png'), pygame.image.load('L2.png'), pygame.image.load('L3.png'),
pygame.image.load('L4.png'), pygame.image.load('L5.png'), pygame.image.load('L6.png'),
pygame.image.load('L7.png'), pygame.image.load('L8.png'), pygame.image.load('L9.png')]
bg = pygame.image.load('bg.jpg')
char = pygame.image.load('standing.png')
clock = pygame.time.Clock()
x = 50
y = 50
width = 64
height = 64
vel = 5
isJump = False
jumpCount = 10
left = False
right = False
walkCount = 0
run = True

在这里，我定义了每个动作的帧和相应的图片。问题来自这里，但我不明白为什么

def redrawgamewindow():
global walkCount
window.blit(bg, (0, 0))
pygame.draw.rect(window, (255, 255, 255), (x, y, width, height))

if walkCount + 1 >= 27:
walkCount = 0
if left:
window.blit(walkLeft[walkCount // 3], (x, y))
walkCount += 1
elif right:
window.blit(walkRight[walkCount // 3], (x, y))
walkCount += 1
else:
window.blit(char, (x, y))
walkCount = 0
pygame.display.update() 

while run:
clock.tick(27)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT] and x > vel:
x -= vel
right = False
left = True
elif keys[pygame.K_RIGHT] and x < 500 - (width + vel):
x += vel
right = True
left = False
else:
right = False
left = False
walkCount = 0
if not isJump:
if keys[pygame.K_UP] and y > vel:
y -= vel
if keys[pygame.K_DOWN] and y < 500 - (height + vel):
y += vel
if keys[pygame.K_SPACE]:
isJump = True
right = False
left = False
else:
if jumpCount >= -10:
neg = 1
if jumpCount < 0:
neg = -1
y -= (jumpCount * abs( jumpCount))*0.5
jumpCount -= 1
else:
isJump = False
jumpCount = 10
redrawgamewindow()
pygame.quit()

显示的错误是

/Users/Thomas.V/Documents/Documents/Perso/Coding /Python /Pycharm Projects/Pygame.py:40: DeprecationWarning: an integer is required (got type float).  Implicit conversion to integers using __int__ is deprecated and may be removed in a future version of Python.
pygame.draw.rect(window, (255, 255, 255), (x, y, width, height))

Answer 1

引起警告是因为y不是整数值，因为

y -= (jumpCount * abs( jumpCount))*0.5

通过四舍五入y来消除警告(请参阅round(：

pygame.draw.rect(window, (255, 255, 255), (x, round(y), width, height))
