Question

我们遇到的错误是：

File "C:/Games/nyuszi/game.py", line 51, in <module>
   for x in range(width/grass.get_width() // 1):
TypeError: 'float' object cannot be interpreted as an integer

这是我的新手，所以不要自大。

我们需要紧急情况帮助，我们还有1天的时间来解决此问题。

# 1 - Import library
import pygame
from pygame.locals import *

# 2 - Initialize the game
pygame.init()
width, height = 640, 480
screen=pygame.display.set_mode((width, height))
keys = [False, False, False, False]

# 4 - keep looping through
running = 1
exitcode = 0
while running:
    badtimer-=1
    # 5 - clear the screen before drawing it again
    screen.fill(0)
    # 6 - draw the player on the screen at X:100, Y:100
    for x in range(width/grass.get_width()+1):
        for y in range(height/grass.get_height()+1):
            screen.blit(grass,(x*100,y*100))
    screen.blit(castle,(0,30))
    screen.blit(castle,(0,135))
    screen.blit(castle,(0,240))
    screen.blit(castle,(0,345 ))

Answer 1

range的参数必须是整数值。 /（除法）运算符的结果可以是浮点值。请改用//（楼层划分）运算符：
（请参见Binary arithmetic operations）

for x in range(width // grass.get_width()+1):
    for y in range(height // grass.get_height()+1):
        screen.blit(grass,(x*100,y*100))

或者，您可以通过int或round将结果转换为整数值。例如：

for x in range(int(width / grass.get_width()) + 1):
    for y in range(int(height / grass.get_height()) + 1):
        screen.blit(grass,(x*100,y*100))

这是我朋友的游戏，我们似乎无法通过浮动解决此问题
