java - Jython UnboundLocalError - 尝试了全局类型但仍然不起作用

Question

我正在开发星球大战星系模拟器，我们使用的脚本语言是 Jython。我无法弄清楚如何在 def 之外定义变量。这是错误..

UnboundLocalError:赋值前引用了局部变量“actorFunds”

还有代码(删掉很多不必要的东西......没有类)

commandArgs = ""
commandLength = 0
globalTarget = SWGObject
globalActor = CreatureObject
tipAmount = 0
actorFunds = 0
totalLost = 0
bankSurcharge = 0

def run(core, actor, target, commandString):
    global globalTarget
    global globalActor
    global commandArgs
    global commandLength
    global tipAmount
    global bankSurcharge
    global actorFunds
    global totalLost

    globalTarget = target
    globalActor = actor
    commandArgs = commandString.split(" ")
    commandLength = len(commandArgs)
    tipAmount = commandArgs[0]
    bankSurcharge = int(0.05) * int(tipAmount)
    actorFunds = actor.getBankCredits()
    totalLost = int(tipAmount) + bankSurcharge

     .......
return

def handleBankTip(core, owner, eventType, returnList):

if eventType == 0:
    if int(totalLost) > globalActor.getBankCredits():
        globalActor.sendSystemMessage('You do not have ' + str(totalLost) + ' credits (surcharge included) to tip the desired amount to ' + globalTarget.getCustomName() + '.')
        return
    if int(tipAmount) > 0 and int(actorFunds) >= int(totalLost):
        return
return

当我到达 actorFunds 时，它提供了错误...

我查了好久也没找到原因。我希望它像 java 一样简单，带有一个“this”...

将声明的变量放在等式的左侧。

def run(core, actor, target, commandString):

    target = globalTarget 
    actor = globalActor 

通过写:

globalTarget = target

您正在为 globalTarget 分配 target 的值。而不是创建一个名为 target 的变量。
