Case: [Coop] Tank is spawned, but is not angry yet.
He becomes angry as soon as some survivor gets to him close enough, so he begins to chase survivor.
So, how to detect (yes / no) if Tank angry (chase anybody)?
PS. I tried to dump tank entity props with tEntDev,
but I don't see anything reliable in differences.
PPS. Previously, I used "m_zombieState", but it seems it's not reliable,
because it becomes 1 -> 0 as soon as m_lookatPlayer becomes X -> -1 (when tank losing the target, like player hides behind the wall).
