function Trig_gamecache_FilterFunc takes nothing returns boolean

function Trig_gamecache_Conditions takes nothing returns boolean

其中这一段
[codes=jass]
if GetUnitAbilityLevel(GetFilterUnit(), 'BHtc') > 0 and not HaveStoredInteger(udg_GC, I2S(h2i(GetFilterUnit())), "ThunderClapTimer")

选取单位'BHtc'技能等级大于0 并且选取单位没有被绑定特定计时器
AND后面的都好理解 这个'BHtc'是个什么技能啊?  判断选取单位这个技能等级大于0 到底有什么意义

zhuzeitou

BHtc是某个buff的id，这句就是判断是否拥有buff

Renee

这个是判断单位身上有没有雷霆一击的buff~~

楼主只要明白~~

1]很多用于buff的函数同样能作用于技能~~反之亦然~~当然不是所有~~比如删除技能的函数同样可以用于删除buff~~但添加技能的函数却无法用于添加buff~~

2]buff也是有等级的~~这个等级等于施展这个buff的技能的等级~~通常来说单位身上有buff~~这个buff的等级显然就会在1级以上~~所以通常用这个方式来判断单位身上是否有buff~~单位身上是否有技能也一样~~当然这个法子并非最严密的~~因为实际上存在0级的技能~~不过一般情况下这样用没有任何问题~~
