Render Distance For Npc's Like Minecraft

im Creating A Game Like Slime Rancher But The Game Performance Is Bad Because There Are A Lot Of Slimes, I Tried To Fix It And It Doesn’t Work, It Despawns Npc’s But Doesn’t Render Them Back, Here’s What Iv’e Done So Far:

Server:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local Slimes = ReplicatedStorage.Slimes

local RenderingRange = 100

function SpawnSlime(spawnPart, Type, PlayerRootPart)
	local Slime = Slimes:FindFirstChild(Type)
	
	if Slime then
		Slime = Slime:Clone()
		Slime.Parent = workspace.GeneratedSlimes
		Slime:MoveTo(spawnPart.Position + Vector3.new(math.random(-10,10), 0, math.random(-10,10)))
			Slime.Parent = workspace.GeneratedSlimes
		
		if Type == "CommonSlime" then
			Slime.Head.Color= Color3.new(math.random(0,255), math.random(0,255), math.random(0,255))
		end
		
		while wait() do
			local Distance = (Slime.HumanoidRootPart.Position - PlayerRootPart.Position).Magnitude
			if Distance > RenderingRange then
				Slime.Parent = game.ReplicatedStorage.DespawnedSlimes
			end
		end
	else
		warn("The Slime Named:", Type, "DoesNotExist")
	end
end

Players.PlayerAdded:Connect(function(player)
	local Character = player.Character or player.CharacterAdded:Wait()
	if Character then
		local PlayerRootPart = Character:WaitForChild("HumanoidRootPart")
		for index, spawnpart in pairs(workspace.SlimeSpawn:GetChildren()) do
			spawnpart.Transparency = 1
			local random = math.random(10,15)
			spawnpart:SetAttribute("Amount", random)
			spawnpart:SetAttribute("MaxRandom", random)
			for i=7, random do
				coroutine.wrap(SpawnSlime)(spawnpart, "CommonSlime", PlayerRootPart)
			end
		end
	end
end)

I Know I Done Something Wrong But I Dont Know What Is It :thinking:

There is no mechanism to bring the slime back into workspace.GeneratedSlimes when the player comes within range again

I Think I’ve Got It!
Im Gonna Create An Event That Will Wait Until The Player Returns In Range

And I Think It Doesn’t Work Because This:

function SpawnSlime(spawnPart, Type, PlayerRootPart)
	local Slime = Slimes:FindFirstChild(Type)
	
	if Slime then
		Slime = Slime:Clone()
		Slime.Parent = workspace.GeneratedSlimes
		Slime:MoveTo(spawnPart.Position + Vector3.new(math.random(-10,10), 0, math.random(-10,10)))
			Slime.Parent = workspace.GeneratedSlimes
		
		if Type == "CommonSlime" then
			Slime.Head.Color= Color3.new(math.random(0,255), math.random(0,255), math.random(0,255))
		end
		
		while wait() do
			local Distance = (Slime.HumanoidRootPart.Position - PlayerRootPart.Position).Magnitude
			if Distance > RenderingRange then
				Slime.Parent = game.ReplicatedStorage.DespawnedSlimes
			end
		end
	else
		warn("The Slime Named:", Type, "DoesNotExist")
	end
end

This Function When The Slime Gets Cloned All This Chunk Of Code Goes To The Slime, So If I Return The Event Is In The Server And Not In The Slime Anymore!

Yes, that is correct. You’ll need a system in the main script to periodically check for slimes that become in range again and render them back in.

#5

You could also just enable StreamingEnabled, and remove the load in and out code

#6

What Is StreamingEnabled?
Because I Don’t Know All Of The Lua Coding Language ._.

#7

Change wait to game[“Run Service”].Stepped:Wait()

#8

you mean this: wait()?
if it This ill’Try

Yes that it’ll scale with game performance and it wont be laggy. Its good for things that constantly run

oh wait.
i think im an idiot,

		while RunService.Stepped:Wait() do
			local Distance = (Slime.HumanoidRootPart.Position - PlayerRootPart.Position).Magnitude
			if Distance > RenderingRange then
				Slime.Parent = game.ReplicatedStorage.DespawnedSlimes
			end
		end

i didn’t add an else ._.

I WAS TRUE i Didn’t Add An Else In The If Statement

Sorry for the late response, but here’s a documentation article about Streaming: Instance Streaming | Documentation - Roblox Creator Hub

oh and it was enabled automatically
