变量不会在IF语句中改变

我试图制作一个非常简单的RPG战斗系统。变量不会在IF语句中改变

但当卫生低于0和什么也不做有一个错误：

jack_battle_loop_1 = True 
while jack_battle_loop_1: 
    battle_menu() 
    choise = input("> ") 
    if choise == "1": 
     #(jack_health + jack_defense) - my_damage = jack_health 
     jack_health = (jack_health + jack_defense) - random.randrange(20, 25) 
     #Processing the updated enemy health 
     print(deskemon + " HAVE INFLICTED " + str(random.randrange(20, 25)) + " TO CHIPHEAD") 
     print("CHIPHEAD HAS " + str(jack_health) + " HITPOINTS LEFT!") 
     time.sleep(1) 
     print("...") 
     time.sleep(1) 
     print("...") 
     time.sleep(1) 
     print("...") 
     time.sleep(1) 
     #(my_health + my_defense) - jack_damage = my_health 
     my_health = (my_health + my_defense) - jack_damage 
     print("CHIPHEAD HAVE INFLICTED " + str(jack_damage) + " TO " + deskemon) 
     print(deskemon + " HAS " + str(jack_health) + " HITPOINTS LEFT!") 
     jack_battle_loop = True 
    elif jack_health <= 0: 
     jack_battle_loop = False 
    elif my_health <= 0: 
     jack_battle_loop = False 
    elif choise == "": 
     jack_battle_loop = True

但是，相反，它输出这样的：

TIMOHA HAVE INFLICTED 23 TO CHIPHEAD 
CHIPHEAD HAS -24 HITPOINTS LEFT!

（它的 “选择”，顺便说一句） –

的elif语句只有choise != "1"执行。看起来检查健康的if应独立于检查选项的if。

喜欢的东西

if choice == "1": 
    # do stuff 
if jack_health <= 0 or my_health <= 0: 
    jack_battle_loop = False

后试试这个您如果的choise == “1”：行：

jacksdamage=random.randrange(20, 25) 
    jack_health = (jack_health + jack_defense) - jacksdamage 
    if jack_health<=0: 
     print "Jack recieved %.i damage and was killed!"%(jacksdamage) 
     break 
    else: 
     print "Jack took %.i damage. from CHIPHEAD."%(jacksdamage) 
     print "Jack has %.i hitpoints left."%(jack_health) 
    for _ in range(5): 
     time.sleep(1) 
     print "..." 
    mydamage=random.randrange(20,25) 
    my_health = (my_health + my_defense) - mydamage 
    if my_health<=0: 
     print deskemon+' took %.i damage from jack and was killed!'%(mydamage) 
     break 
    else: 
     print deskmon+' took %.i damage from jack.'%(mydamage) 
     print deskmon+' has %.i health left.'%(my_health) 
    for _ in range(5): 
     time.sleep(1) 
     print "..."
