sorry Silvers, I found another issue
if's not good to always set "m_isGoingToDie" to 0
if the prop is 0, and next hurt damage equal or higher than real health, "m_isGoingToDie" will becomes 1, and reduce 1.0 damge(or get extra 1.0 health buffer)
always set "m_isGoingToDie" to 0, means always reduce 1.0 damage, for example, normal difficulty horde hit from front damage will reduce to 1
I have another method to block vocalize
