Iâm trying to code a âHigh Scores programâ, which simply accesses values
from a separate file and then displays them on the screen. Hereâs my code:
#high scores program
#imports score values from a seperate file an prints them on the
screen
import pygame,sys,random
from pygame import *
pygame.init()
WINWIDTH=640 #width of the window in pixels
WINHEIGHT=420 #height of the window in pixels
FPS=30 #frames per second
# r g
b
RED= (255, 0, 0)
BLACK=( 0, 0, 0)
def get_text(pos,text,size,color):
"""Returns a text surface and a rect object based on the
parameters given to be displayed on the screen. """
BASICFONT=pygame.font.Font('freesansbold.ttf',size)
textSurf=BASICFONT.render(text,True,RED)
rectObj=textSurf.get_rect()
retcObj.center=(size)
return textSurf,rectObj
def displayScores():
"""Displays the high scores on the screen. """
#keep track of how many scores have been displayed on
the screen
index=0
#add each line of the high scores file into a list
scores=[]
for line in scoresFile:
scores.append(line)
#a list containing all of the score surfaces and rect
objects
scoresList=[]
while True:
DISPLAYSURF.fill(BLACK)
for event in pygame.event.get():
#event loop
if
event.type==QUIT:
pygame.quit()
sys.exit()
for i in scores:
index+=1
scoreSurf,scoreObj=get_text((WINWIDTH/2,(index*10)),'%s.:%s'%(index,i),15,RED)
scoresList.append([scoreSurf,scoreObj])
DISPLAYSURF.blit(scoresList[0][0],scoresList[0][1])
pygame.display.update()
FPSCLOCK.tick(FPS)
while True: #main loop
global DISPLAYSURF,FPSCLOCK
DISPLAYSURF=pygame.display.set_mode((WINWIDTH,WINHEIGHT))
pygame.display.set_caption('High Scores!')
FPSCLOCK=pygame.time.Clock()
#randomly select a number between 1 and 100 to be added
to the high scores
randomScore=random.randint(0,100)
#open the high scores file in read/ append mode
scoresFile=open('highScores.txt','a+')
displayScores()
scoresFile.close()
Everytime I run the program I get an IndexError saying that when the line
âDISPLAYSURF.blit(scoresList[0][0],scoresList[0][1])â runs, the list index is
out of range. Can anyone help me? Iâm using Python
