我有一个绘制健康栏的功能，使用全局变量设置绿色矩形的宽度以覆盖预设的红色矩形。当我改变我的代码以便能够让怪物实际损坏墙壁时，rect参数停止工作。
我已经尝试了许多不同的方法来使它工作，但没有一个工作。
这是我的代码：
import pygame
import random
pygame.init()
displayWidth = 500
displayHeight = 600
currentWeapon = 'Bow'
projectileLength = 64
projectileHeight = 10
wallHealth = 100
coinCount = 0
currentWave = 0
black = (0, 0, 0)
white = (255, 255, 255)
darkGrey = (100, 100, 100)
orange = (200, 100, 0)
brightOrange = (250, 125, 0)
green = (0, 200, 0)
brightGreen = (0, 255, 0)
red = (200, 0, 0)
gameDisplay = pygame.display.set_mode((displayWidth, displayHeight))
pygame.display.set_caption('Project')
clock = pygame.time.Clock()
wallImg = pygame.image.load('buildings/wall.png')

pygame.draw.rect(gameDisplay, black, (0, (displayHeight/2)-1, displayWidth, 2))

def coins():
global coinCount
gameDisplay.blit(coinImg, (displayWidth-100, 25))
def wallHealth(health):
global wallHealth
pygame.draw.rect(gameDisplay, red, (displayWidth - 110, 5, 100, 15))
pygame.draw.rect(gameDisplay, brightGreen, (displayWidth - 110, 5, wallHealth, 15))
def text_objects(text, font, colour):
textSurface = font.render(text, True, colour)
return textSurface, textSurface.get_rect()
def button(msg, x, y, w, h, ic, ac, action=None):
mouse = pygame.mouse.get_pos()
click = pygame.mouse.get_pressed()
if x+w > mouse[0] > x and y+h > mouse[1] > y:
pygame.draw.rect(gameDisplay, ac, (x, y, w, h))
if click[0] == 1 and action != None:
action()
else:
pygame.draw.rect(gameDisplay, ic, (x, y, w, h))
smallText = pygame.font.Font('freesansbold.ttf', 10)
textSurf, textRect = text_objects(msg, smallText, black)
textRect.center = ((x+(w/2)), (y+(h/2)))
gameDisplay.blit(textSurf, textRect)
def weapon():
global currentWeapon

if currentWeapon == 'Bow':
if mouse[1] < (displayHeight/2)-20:
gameDisplay.blit(bowImg, (0, mouse[1]-20))

gameDisplay.blit(magicBoltImg, (0, (displayHeight/2)-40))

def projectile1(x, y):

def game_loop():

gameExit = False
while not gameExit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_1:

blacksmith()
magicBuilding()
if click[0] == 1 and projectile1Fired == False and mouse[1] < displayHeight/2:
projectile1Fired = True
projectile1X = 0
projectile1Y = mouse[1]-5
if monsterSpawned == False:
monsterSpawned = True
monsterX = displayWidth
monsterY = random.randrange(0, displayWidth/2-50)
if monsterSpawned == True:
monster(monsterX, monsterY)
if monsterX == 50:
monsterSpawned = False
wallDamaged = True
if projectile1Fired == True:
projectile1(projectile1X, projectile1Y)
projectile1X += projectile1Xchange
monsterX -= monsterXchange
if projectile1X > displayWidth:
projectile1Fired = False
if projectile1Fired == True:
if projectile1X + projectileLength > monsterX:
if projectile1Y > monsterY and projectile1Y + projectileHeight < monsterY + 50:
monsterSpawned = False
projectile1Fired = False
if wallDamaged == True:
wallHealth -= monsterDamage
wallDamaged = False
coins()
wallHealth(wallHealth)
pygame.display.update()
clock.tick(60)
game_loop()
pygame.quit()
quit()
我认为我的代码部分可能是问题的一部分：
wallHealth = 100
brightGreen = (0, 255, 0)
red = (200, 0, 0)
def wallHealth(health):
global wallHealth
pygame.draw.rect(gameDisplay, red, (displayWidth - 110, 5, 100, 15))
pygame.draw.rect(gameDisplay, brightGreen, (displayWidth - 110, 5, wallHealth, 15))
def game_loop():
global wallHealth
monsterDamage = 10
wallDamaged = False
if wallDamaged == True:
wallHealth -= monsterDamage
wallDamaged = False
我不知道它为什么不起作用，我希望得到一些有用的建议。
答案 0 :(得分：1)
在wallHealth函数中查看此代码：
pygame.draw.rect(gameDisplay, brightGreen, (displayWidth - 110, 5, wallHealth, 15))
这里你将一个元组传递给pygame.draw.rect，但该元组由一个整数，一个第二个整数，wallHealth函数和一个第三个整数组成。它应该是四个整数。
现在你看到了你的问题。
简而言之：要么将存储墙体健康量的变量重命名，要么重命名该功能。
您不能同时对不同的事物使用相同的名称。
