关于动态注册的教程

//当触发注册的事件时调用的函数
function OnUnitAmort takes nothing returns nothing
      //设置触发单位为无敌
      call SetUnitInvulnerable( GetTriggerUnit(), true )
      //破坏这个触发器,即下面的RegisterUnitAmortEvent所创建的触发器
      //这样就不会导致该触发被多次调用,并且还能清理该触发所占用的内存
      call DestroyTrigger(GetTriggeringTrigger())
endfunction

//注册模板
function RegisterUnitAmortEvent takes unit witchUnit returns nothing
      //创建一个触发器
      local trigger rTrg = CreateTrigger()
      //为创建的触发器注册事件:当单位witchUnit的生命值小于或等于50的时触发事件
      call TriggerRegisterUnitLifeEvent( rTrg , witchUnit, LESS_THAN_OR_EQUAL, 50 )
      //注册触发器事件响应后所调用的函数
      call TriggerAddAction( rTrg, function OnUnitAmort )
endfunction

为什么老狼说这个写法很笨？

以下是标准的触发创建和删除~
[codes=jass]
function DestroyTriggerAllById takes integer t returns nothing
    call TriggerRemoveCondition(i2tg(t),i2tc(GetStoredInteger(udg_GC,I2S(t),"TriggerCondition")))
    call DestroyTrigger(i2tg(t))
    call FlushStoredMission(udg_GC,I2S(t))
endfunction

function DestroyTriggerAll takes trigger trg returns nothing
    call TriggerRemoveCondition(trg,i2tc(GetStoredInteger(udg_GC,I2S(h2i(trg)),"TriggerCondition")))
    call DestroyTrigger(trg)
    call FlushStoredMission(udg_GC,I2S(h2i(trg)))
endfunction

//========================================================
function RegisterUnitAmortCond takes nothing returns nothing
      call SetUnitInvulnerable(GetTriggerUnit(), true)
      call DestroyTriggerAll(GetTriggeringTrigger())
endfunction

function RegisterUnitAmortEvent takes unit witchUnit returns nothing
    local trigger trg = CreateTrigger()
    call TriggerRegisterUnitStateEvent(trg, witchUnit, UNIT_STATE_LIFE, LESS_THAN_OR_EQUAL, 50)
    call StoreInteger(udg_GC,I2S(h2i(trg)),"TriggerCondition",TriggerAddCondition(trg,Condition(function RegisterUnitAmortCond)))
    set trg = null
endfunction
