Help with NPC spawner

GameMaster4268 · February 12, 2023, 1:01pm

I need help with making an NPC spawner. I want a limit for each NPC to spawn and spawn the NPC on the right spawn.

local serverStorage = game:GetService("ServerStorage")
local replicatedStorage = game:GetService("ReplicatedStorage")

local npcs = workspace:WaitForChild("Npcs")
local npcSpawns = workspace:WaitForChild("NpcSpawns")
local npcsFolder = serverStorage:WaitForChild("Npcs")

local npcLimit = 100

local dummyLimit = 75
local copsLimit = 25

local function randomSpawn()
	local children = npcSpawns:GetChildren()
	local random = children[math.random(1, #children)]
	if random then
		return random
	end
end

local function Generate()
	local children = npcsFolder:GetChildren()
	local randomNpc = children[math.random(1, #children)]
	local randomSpawner = randomSpawn()
	
	if randomNpc then
		local new = randomNpc:Clone()
		new:PivotTo(CFrame.new(randomSpawner.Position))
		new.Parent = npcs
	end
end

local function spawner()
	local child = #npcs:GetChildren()
	if child < npcLimit then
		Generate()
	end
end

while task.wait(0.1) do
	spawner()
end

I want them to spawn on the right spawn depending on the name.

Is the code not working…? If so, what is the error?

It works but I want to add a limit of a certain NPC and place the NPC on the right spawn.

GameMaster4268 · February 12, 2023, 2:04pm

local npcLimit = 100

local dummyLimit = 75
local copsLimit = 25

GameMaster4268 · February 12, 2023, 2:04pm

Right now, the code just spawns NPC and places the NPC on random spawns.

Just make a value and decrease it everytime NPC spawns. And make it will not spawn if the value 0.

GameMaster4268 · February 12, 2023, 2:30pm

How can I detect how many of the NPC’s there are?

local serverStorage = game:GetService("ServerStorage")
local replicatedStorage = game:GetService("ReplicatedStorage")
local Modules = replicatedStorage:WaitForChild("Modules")
local Remotes = replicatedStorage:WaitForChild("Remotes")

local npcs = workspace:WaitForChild("Npcs")
local npcSpawns = workspace:WaitForChild("NpcSpawns")
local npcsFolder = serverStorage:WaitForChild("Npcs")

local npcLimit = 100

local dummyLimit = 75
local copsLimit = 25

local dummies = 0
local cops = 0

local function randomSpawn()
	local children = npcSpawns:GetChildren()
	local random = children[math.random(1, #children)]
	if random then
		return random
	end
end

local function Generate()
	local children = npcsFolder:GetChildren()
	local randomNpc = children[math.random(1, #children)]
	local randomSpawner = randomSpawn()
	
	if randomNpc then
		local new = randomNpc:Clone()
		new:PivotTo(CFrame.new(randomSpawner.Position))
		new.Parent = npcs
	end
end

local function spawner()
	local child = #npcs:GetChildren()
	if child < npcLimit then
		Generate()
	end
end

npcs.ChildAdded:Connect(function(child)
	if child.Name == "Dummy" then
		dummies += 1
	elseif child.Name == "Cop" then
		cops += 1
	end
end)

npcs.ChildRemoved:Connect(function(child)
	if child.Name == "Dummy" then
		dummies -= 1
	elseif child.Name == "Cop" then
		cops -= 1
	end
end)

while task.wait(0.1) do
	spawner()
end

Is something like this would help ?

--//Services//--
local ServStorageService = game:GetService("ServerStorage")

local NpcTable = {
	Total = {0, 100};
	Dummy = {0, 75};
	Cops = {0, 25}
}

local function NpcRemoved(Child)
	NpcTable.Total[1] -= 1
	for Key, Values in pairs(NpcTable)do
		if Key == Child.Name then
			Key[1] -= 1

	end
end

local function Spawning(SelectedNpc, SelectedSpawn)
	local Clone = NpcsFolder:FindFirstChild(SelectedNpc):Clone()
	Clone:PivotTo(CFrame.new(SelectedSpawn.Position))
	Clone.Parent = Npcs
end

	end))

Make another value that increases everytime a NPC added.

GameMaster4268 · February 12, 2023, 3:01pm

I edited the code a bit and it worked!

local serverStorage = game:GetService("ServerStorage")
local replicatedStorage = game:GetService("ReplicatedStorage")
local Modules = replicatedStorage:WaitForChild("Modules")
local Remotes = replicatedStorage:WaitForChild("Remotes")

local npcs = workspace:WaitForChild("Npcs")
local npcSpawns = workspace:WaitForChild("NpcSpawns")
local npcsFolder = serverStorage:WaitForChild("Npcs")

local limit = 100

local NpcTable = {
	Dummy = {0, 75},
	Cop = {0, 25}
}

local function checkLimit()
	local children = npcs:GetChildren()
	if #children >= limit then
		return true
	else
		return false
	end
end

local function NpcRemoved(Child)
	for Key, Values in pairs(NpcTable)do
		if Key == Child.Name then
			Key[1] -= 1
		end
	end
end

local function Spawning(SelectedNpc, SelectedSpawn)
	local newNpc = SelectedNpc:Clone()
	newNpc:PivotTo(CFrame.new(SelectedSpawn.Position + Vector3.new(0,3,0)))
	newNpc.Parent = npcs
end

local function randomNpc()
	local children = npcsFolder:GetChildren()
	local randomNpc = children[math.random(1, #children)]

	if randomNpc then
		return randomNpc
	end
end

local function Randomise()
	local NpcState = false
	local SpawnState = false
	local RandomTableNpc = {}
	local Spawners = npcSpawns:GetChildren()
	local SelectedNpc = nil
	local SelectedSpawn = nil
	
	for Index in pairs(NpcTable) do
		if checkLimit() == false then
			table.insert(RandomTableNpc, Index)
		end
	end
	
	repeat
		local RandomNpc = RandomTableNpc[math.random(1, #RandomTableNpc)]
		if NpcTable[RandomNpc][1] < NpcTable[RandomNpc][2] then
			NpcState = true
			NpcTable[RandomNpc][1] += 1
			SelectedNpc = randomNpc()
		end
		task.wait(0.1)
	until NpcState == true
	
	repeat
		local RandomSpawn = Spawners[math.random(1, #Spawners)]
		if RandomSpawn.Name == SelectedNpc.Name then
			SpawnState = true
			SelectedSpawn = RandomSpawn
		end
		task.wait(0.1)
	until SpawnState == true
	
	Spawning(SelectedNpc, SelectedSpawn)
end

npcs.ChildRemoved:Connect(function(Child)
	NpcRemoved(Child)
end)

coroutine.wrap(function()
	while task.wait(0.1) do
		if checkLimit() == false then
			Randomise()
		end
	end
end)()
