请教个数组的问题

[quote]local buffs = {};
table.insert(buffs, { BuffIndex = buffIndex, Name = name, TimeLeft = timeLeft, MaxTime = maxtime, OwnOrder = buffSettings.DisplayOrder, Settings = buffSettings});[/quote]

RoguePowerBars中定义了这么一个数组,后面有调用是

[quote]rogePowerBarFrame.id = buff.BuffIndex;
rogePowerBarFrame.timeleft = buff.TimeLeft;
rogePowerBarFrame.maxtime = buff.MaxTime;[/quote]

我又在其中新定义了个数组
[quote]local debuffs = {};
table.insert(debuffs, { BuffIndex = buffIndex, Name = name, TimeLeft = timeLeft, MaxTime = maxtime, OwnOrder = buffSettings.DisplayOrder, Settings = buffSettings});[/quote]

调用照葫芦画瓢是
[quote]rogePowerBarFrame.id = debuff.BuffIndex;
rogePowerBarFrame.timeleft = debuff.TimeLeft;
rogePowerBarFrame.maxtime = debuff.MaxTime;[/quote]

怎么就报错了attempt to index global 'debuff' (a nil value),出错行就是rogePowerBarFrame.id = debuff.BuffIndex;

还有,插件原本定义的数组明明是buffs,  怎么后面就变成buff.BuffIndex之类的呢?
不是应该buffs.BuffIndex才对么

如果buff.BuffIndex不是代表buffs这个数组的话我真找不出这个是什么意思了

我错了,看来buff.BuffIndex和先前定义的buffs的确没关系
那么请问buff.BuffIndex到底是代表什么呢?
是不是wow自带函数?

月色狼影 发表于 2008-8-9 19:39

拼写错误
你前面写了
local debuffs = {}
后面引用 怎么成debuff了...

bluelunace 发表于 2008-8-9 21:52

但是这个插件原本定义的就是local buffs = {}
后面也只见得到buff.BuffIndex之类的
仔细看了下,后面的buff.BuffIndex应该是别的东西
但全部查找了下也没看到对buff的定义
所以搞不明吧了
后来我把我的debuff.BuffIndex也改成buff.BuffIndex
终于生效可以监视debuff了
但还是应该有些错误,有些时候计时条会不刷新或者卡住,我实在想不出来该怎么改了

月大能不能帮忙改改
目的就是为了使RoguePowerBars能显示目标debuff计时条

这个是原版的
[attach]7203[/attach]

这个是我修改过的,在RoguePowerBars_Settings.lua里面加上了割裂和致命毒药的选项
RoguePowerBars.lua文件改了function UpdateBuffs(),   function SetStatusBarBuff,   function UpadateRoguePowerBars()

[quote]function UpdateBuffs()

    local buffs = {};
    local numBuffs = 0;

    table.insert(buffs, { BuffIndex = buffIndex, Name = name, TimeLeft = timeLeft, MaxTime = maxtime, OwnOrder = buffSettings.DisplayOrder, Settings = buffSettings});

    for x = 1, #buffs do
        numBuffs = numBuffs + 1
        SetStatusBarBuff(numBuffs, buffs[x]);
    end

end

function SetStatusBarBuff(buffId, buff)
    rogePowerBarFrame.id = buff.BuffIndex;
    rogePowerBarFrame.timeleft = buff.TimeLeft;
    rogePowerBarFrame.maxtime = buff.MaxTime;
end[/quote]

哦,我明白了, buffs是个2维数组,buff.BuffIndex就是buffs这个数组中buffId行的BuffIndex列,是这样吧?


另再请教下UNIT_AURA这个事件如何使用
[quote]
function RoguePowerBar_OnEvent(event)
RoguePowerBar_EventHandler[event](arg1, arg2, arg3, arg4, arg5);
end

RoguePowerBar_EventHandler = {};

RoguePowerBar_EventHandler["UNIT_AURA"] = function()
UpdateBuffs();
end
[/quote]
这样有问题么?或者直接给我个资料链接也行
