Pygame评分问题

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（ex> 200），它应该将事实（例如SWAG'）改变为它在'if'陈述中所说的事实，但由于'fact =“而保持不变， “”。

Answer 1

您还没有分配给fact，你是比较它。我想，你希望是

if score < 200: 
     fact = 'NOTHING' 

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

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

还要注意，在200分的玩家将获得一个空白的事实，作为第一个条件仅小于200，接下来只比200

更大

Answer 2

您代码没有设置fact当比分是200你必须检查score >= 200或使用

if score < 200: 
    fact == 'NOTHING' 

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

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

BTW：你可以设置face=''前while

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()

@Margius有权利。您可以使用==，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()
