Countdown

[NiLSPACE]

What do you want to schedule? If you want to set a block after some ticks you can use QueueSetBlock. If you want to schedule a function... You can't sorry. We do have an issue on github for it: https://github.com/mc-server/MCServer/issues/150

I did once create a plugin that counted down using OnTick and then execute it. You could maybe use the code from that:

Table = {}

function Initialize(Plugin)
	PLUGIN = Plugin
	Plugin:SetName("Scheduler")
	Plugin:SetVersion(1)
	
	cPluginManager.AddHook(cPluginManager.HOOK_TICK, OnTick)
	
	return true
end

function Add(Function, Parameters, Ticks)
  table.insert(Table, {Function, Parameters, Ticks})
end

function OnTick(Time)
	for I=1, #Table do
		if Table[I][4] < 0 then
			Table[I][2](Table[I][3])
			table.remove(Table, I)
		else
			Table[I][4] = Table[I][4] - 1
		end
	end
end
