VZ psuedo code

controller should have a spawn with whatever VZ respawn timer is.
VZ should not have a spawn
On spawn, the controller will have the loot that the final VZ needs.
on spawn, he will spawn the first VZ.
when VZ spawns he will read the loot on the controller and copy it (this is a bit advanced and not sure of an example, but code exists)
when VZ spawns he will always signal to the controller that he spawned.
the controller will respond to the "ispawned" signal with a signal letting VZ know which phase it is on.
on all subsequent spawns of VZ, the controller also spawns the clones. no logic needed as it is an "Always"
on death of VZ, VZ will spawn the PP (easier him instead of controller as the xyz loc is needed) and signals controller to despawn with timer.

VZ psuedo code:
on spawn
	signal controller i spawned!
	copy loot from controller
end spawn

on signal
	if signal = phase1 then
		set hp event to 75 or what ever first repop hp event is
	elseif signal = phase2 or signal = phase3 then
		set hp event to 50 or whatever
	elseif signal = phase4 then
		is anything needed here? i forgot event
	end if
end signal

on hp event
	signal controller with signal "depopping"
	depop
end hp event

on death
	spawn PP
	signal controller i deaded
end

controller psudeo code
on spawn
	set local phase counter variable = 1
	spawn VZ
end spawn

on signal
	if signal - ispawned then
		signal phase counter to VZ
	elseif signal = depopping then
		phase counter += 1
		spawn VZ
		spawn clones
	elseif signal = deaded then
		depop self with timer
	end
end signal
