Entity spawning loop

[Skashh]

Basically, I'm looking to have certain locations on the map where these entities I've created will spawn and I want them to spawn on a loop but I don't want them to spawn if there is already an entity there. Right now, I just need to know how to set it up so it will keep spawning entities at that location on a timer/loop, I think I could probably figure the rest out myself.

init:

AddCSLuaFile("cl_init.lua")
AddCSLuaFile("shared.lua")
include("shared.lua")

hook.Add("InitPostEntity", "spawnplants", function()
	local plant = ents.Create("cocaine")
	plant:Spawn()
end)

function createPlants()
	local plant1 = ents.Create("cocaine")
	plant1:Spawn()
end

function ENT:Initialize()
	self:SetModel( "models/props/cs_office/plant01.mdl" )

	self:SetMoveType( MOVETYPE_VPHYSICS )
	self:SetSolid( SOLID_VPHYSICS )

	if ( SERVER ) then self:PhysicsInit( SOLID_VPHYSICS ) end

	local phys = self:GetPhysicsObject()
	if ( IsValid( phys ) ) then phys:Wake() end

	self:SetPos(Vector(-2268, -250, -132))
end

BTW: shared and cl_init have nothing important.

It seems pretty simple xD I would think someone would know how to do it. xP

Have a table of all the vectors, make a timer to run every so often, spawn the ent at all the vectors using a for loop.

It's not difficult.

Do a [img]http://wiki.garrysmod.com/favicon.ico[/img] [url=http://wiki.garrysmod.com/page/ents/FindInSphere]ents.FindInSphere[/url] around the spawn vector and loop through ents found and if there the type you want to spawn the skip or if there is none found skip.

This function should work (havent tested it)
[LUA]
function CheckEntExists( class, vec, radius )
for k,v in pairs(ents.FindInSphere(vec, radius)) do
if v:GetClass() == class then
return true
end
end

return false
end
