Pygame分数问题[关闭]

Question

while not done:
    baddieAddCounter = 0
    baddies = []
    score += 1
    fact = ""

    #GIVES PLAYER A NEW FACT EVERYTIME THEY REACH THE TARGET SCORE
    if score < 200:
       fact == 'NOTHING'

    elif score > 200 and score <= 599:
       fact == 'SWAG'

    elif score > 600 and score <= 799:
       fact == 'brehh'


    drawText('Score: %s' % (score), font, screen, 10, 0)
    drawText('Fact: %s' % (fact), font, screen, 10, 40)
    pygame.display.update()

为什么这不起作用？在游戏中，一旦玩家得分达到目标得分（例如 >200），它应该将事实（例如 SWAG'）更改为“if”语句中所说的内容，但由于“事实 =”而保持不变"'。

Answer 1

你没有分配给fact，你是在比较它。我假设你想要的是

if score < 200:
       fact = 'NOTHING'

elif score > 200 and score <= 599:
   fact = 'SWAG'

elif score > 600 and score <= 799:
   fact = 'brehh'

另外请注意，得分为 200 时，玩家将得到一个空白事实，因为第一个条件仅小于 200，而下一个条件仅大于 200。

Answer 2

当分数为 200 时，您的代码未设置 fact。您必须检查 score >= 200 或使用

if score < 200:
   fact == 'NOTHING'

elif score <= 599:
   fact == 'SWAG'

elif score <= 799:
   fact == 'brehh'

顺便说一句：你可以在while之前设置face=''

fact = ""

baddieAddCounter = 0
baddies = []

while not done:
    score += 1

   if score < 200:
      fact == 'NOTHING'

   elif score <= 599:
      fact == 'SWAG'

   elif score <= 799:
      fact == 'brehh'

   drawText('Score: %s' % (score), font, screen, 10, 0)
   drawText('Fact: %s' % (fact), font, screen, 10, 40)
   pygame.display.update()

编辑：

@Margius 是对的。你使用==，但你需要=

fact = ""

baddieAddCounter = 0
baddies = []

while not done:
    score += 1

   if score < 200:
      fact = 'NOTHING'

   elif score <= 599:
      fact = 'SWAG'

   elif score <= 799:
      fact = 'brehh'

   drawText('Score: %s' % (score), font, screen, 10, 0)
   drawText('Fact: %s' % (fact), font, screen, 10, 40)
   pygame.display.update()
