Question

您好我是python的新手，我正在尝试将一个简单的计数器作为延迟来在pygame中显示一些文本，因此它不会立即显示。我想做的是当玩家升级时让文字显示在一个框中。

def TEXT(A, B, C):
    global ONE, TWO, THREE, FOUR
    counter = 0
    text = True
    if text:
        if counter == 10:
            ONE = A
        if counter == 20:
            TWO = B
        elif counter == 30:
            THREE = C
        elif counter == 40:
            ONE = None
            TWO = None
            THREE = None
            text = False
        counter += 1

整个代码似乎工作正常，但我无法让计数器工作。这是完整的程序作为参考：

from pygame import *
from userInterface import Title, Dead
WIN_WIDTH = 640
WIN_HEIGHT = 400
HALF_WIDTH = int(WIN_WIDTH / 2)
HALF_HEIGHT = int(WIN_HEIGHT / 2)
DISPLAY = (WIN_WIDTH, WIN_HEIGHT)
DEPTH = 32
FLAGS = 0

init()
screen = display.set_mode(DISPLAY, FLAGS, DEPTH)
saveState = False

WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GRAY = (30, 30, 30)
FONT = font.SysFont("Courier New", 15)



heroHP = 1000

      'stats': {'str' : 12, # strength

                'int' : 15, # intelligence
                'hp'  : heroHP, # health
                'atk' : [250,350]}} # range of attack values


boss1={'name' : 'Imp',
       'xp' : 0,
       'lvlNext':25,

        char['xp']=char['xp'] - char['lvlNext']
        char['lvlNext'] = round(char['lvlNext']*1.5)
        nStr=0.5*char['stats']['str']+1
        nDex=0.5*char['stats']['dex']+1
        nInt=0.5*char['stats']['int']+1
        print(f'{char["name"]} levelled up to level {char["lvl"]}!') # current level
        A = (f'{char["name"]} levelled up to level {char["lvl"]}!') # current level

        print(f'( INT {round((char["stats"]["int"] + nInt))} - STR {round(char["stats"]["str"] + nStr)} - DEX {round(char["stats"]["dex"] + nDex)} )') # print new stats

如果您只想让counter成为一个全局变量，只在程序开始时设置为0，而不是在每次调用时重置为0的局部变量，那么就这样做了。以同样的方式处理ONE和同一函数中的其他全局变量：

counter =0
def TEXT(A, B, C):
    global ONE, TWO, THREE, FOUR
    global counter
    text = True
    if text:
        if counter == 10:
            # etc.
    counter += 1

唯一的变化是将counter = 0从函数体移动到顶层，并在函数体的开头添加global counter。
