Mouse Target changed fires an event

Help and Feedback Scripting Support
#1

How would I make it so When The target changes it fires an event that let’s the server know what target
the player pointed at , but the event might also fire when the player has clicked (I already have the script for this no worry) But in the server script onserver function it has a while loop how would I change the target variable when the target changes in the function because it doesn’t change the variable while it is already running

also don’t worry I am not going to make it so it fires a server event when the mouse target changes it is just a example

game:GetService("RunService").RenderStepped:Connect(function()

	local mouse = game.Players.LocalPlayer:GetMouse()
	target = mouse.Target
	if target then
		if Player:DistanceFromCharacter(target.Position) < 15 then
			SelectionBox.Adornee = target
			else 
		SelectionBox.Adornee = nil
		end
		
		
		
		if not LastTarget then
			
			LastTarget = target
			
		end
		if target ~= LastTarget then
			
			EventActivate:FireServer(target,MouseHeld,tool)	
			LastTarget = nil
		end
	
	end
end)

So you want to check on the server if the returned Target is different than the last one? If so, you can do something like this:

local RS = game:GetService("ReplicatedStorage")

local event: RemoteEvent
local existing = {}

event.OnServerEvent:Connect(function(player: Player, target: BasePart)
	if existing[player] then
		if existing[player] == target then
			warn("nothing changed")
		else
			warn("omgggg it changed!!")
		end
	end
	
	existing[player] = target
end)

You could try using this, I used it for my game:

local playerInstance = game:GetService("Players").LocalPlayer
local playerMouse = playerInstance:GetMouse()
local remoteEvent = game.ReplicatedStorage.RemoteEvent

playerMouse.Move:Connect(function()
	local target = playerMouse.Target
	
	local function check(lastTarget)
		if tostring(target) ~= lastTarget then
			remoteEvent:FireServer()
		end
	end

	local lastTarget = script.LastTarget
	check(lastTarget.Value)
	lastTarget.Value = tostring(target)
end)

Make sure it’s a LocalScript and it has a StringValue with the name “LastTarget” as a child.

Not sure if it’s what you needed, but this is what I used for my game and it worked. If you need to, you can change some things in the Script to make it detect whenever someone clicked.

local Game = game
local RunService = Game:GetService("RunService")
local Players = Game:GetService("Players")
local Player = Players.LocalPlayer
local Mouse = Player:GetMouse()

local OldTarget = nil

local function OnRenderStep()
	local NewTarget = Mouse.Target
	if NewTarget == OldTarget then return end
	print(NewTarget.Name)
	OldTarget = NewTarget
end

RunService.RenderStepped:Connect(OnRenderStep)
