创建漂浮文字失败的问题

初学Jass处于白痴状态，用Jass写触发如下：
function Trig_burst_damage_Conditions takes nothing returns boolean
    if ( not ( UnitHasBuffBJ(GetAttackedUnitBJ(), 'Bcri') == true ) ) then
        return false
    endif
    return true
endfunction

function Trig_burst_damage_Actions takes nothing returns nothing
    local location unit_point
    local real damage
    local texttag damage_text
    set unit_point = GetUnitLoc(GetAttacker())
    set damage = 4.00 * I2R(GetUnitAbilityLevel(udg_sirius, 'Acri'))
    call CreateTextTagLocBJ( R2S(damage), unit_point, 0, 10, 100, 100, 100, 0 )
    set damage_text = bj_lastCreatedTextTag
    call SetTextTagVelocity( damage_text, 64, 90 )
    call UnitDamageTarget( GetAttacker(), GetAttackedUnitBJ(), damage, true, true, ATTACK_TYPE_HERO, DAMAGE_TYPE_UNIVERSAL, WEAPON_TYPE_WHOKNOWS )
endfunction

//===========================================================================
function InitTrig_burst_damage takes nothing returns nothing
    set gg_trg_burst_damage = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_burst_damage, EVENT_PLAYER_UNIT_ATTACKED )
    call TriggerAddCondition( gg_trg_burst_damage, Condition( function Trig_burst_damage_Conditions ) )
    call TriggerAddAction( gg_trg_burst_damage, function Trig_burst_damage_Actions )
endfunction

结果发现漂浮文字没有显示，其余部分正常，求高人解答……

自己把问题搞定了，貌似是因为透明度设为0的时候不显示（那为什么透明度100也是不显示，严重不解）。
另外这个代码还有小bug，
set damage_text = bj_lastCreatedTextTag
这句后面少个括号，还有就是无排泄了……
