How to add respawn in timed spawns (like CA)?

[Daxter 2]

Hi,

 

I'm working on a map with a timed spawn cycle, like in CA:

 

function map_copy_run_special_garner2( map_copy ) 
	local HowManyNoDead = GetMapActivePlayer(map_copy)
	Notice("Chaos Argent still have survivor: "..HowManyNoDead.." player(s)")
	Every_5_minute = Every_5_minute+1
	if Every_5_minute == 2 then -- 初级宝箱
		local Monster2 = CreateChaEx(859, 6352, 3558, 145, 60,map_copy)
		local Monster3 = CreateChaEx(859, 6761, 13062, 145, 60,map_copy)
(...)
		SetChaLifeTime(Monster2,299050)
		SetChaLifeTime(Monster3,299100)
(...)

	end

However, and different from CA, I want to have waves where the mobs respawn until the next wave is summoned (at which time the mobs from the previous wave would disappear and stop respawning).

Any suggestions?

i think u can use the same function, just changing the mobs respawn, in CA respawn every 60 seconds, if u want to kill x mob and didnt respawn, 
something like:
function map_copy_run_special_MapName( map_copy )

Every_5_minute = Every_5_minute+1

if Every_5_minute == 2 then -- Time for spawn mobs when maze open (in this case when have past 2 mins)

local Monster2 = CreateChaEx(MobID, XX00, YY00, 180, RespawnTime,map_copy)

SetChaLifeTime(Monster2,299050)

if Every_5_minute == 3 then

local Monster3 = CreateChaEx(MobID, XX00, YY00, 180, RespawnTime,map_copy)

SetChaLifeTime(Monster3,299050)

if Every_5_minute == 4 then

local Monster4 = CreateChaEx(MobID, XX00, YY00, 180, RespawnTime,map_copy)

SetChaLifeTime(Monster4,299050)

end
this funcion make the previous wave disappear and stop respawning, or idk what u want to do, just have to change the map name and adding to the file ctrl.lua of that map
