使用样例

-- 设置 是否播放残影  
function BonesEffect:setPlayGhostTime(nGhostTime)
    self.m_nGhostTime = nGhostTime
end

-- 播放 残影
function BonesEffect:playGhost(monomer)

    if monomer then  

        local t = self.m_nGhostTime/1000  -- 播放时间 
        local wt = 0.4 -- 残影存在时间 渐影 

        if self.m_nGhostTime and t>0 then 
            g_PlayShadowAction( monomer.m_nMonomer,t,GAME_FRAME_FLUENT*3,cc3BLUE,wt)
        end 

        --if self.m_isSkillBreak then 
        monomer:setDisappearSkill(self.m_skillMgr,self.m_isSkillBreak)
        --end 
    end
