Detecting what a player clicked

Help and Feedback Scripting Support
#1

Basically I want to make a tool that when the player clicks something, it will print the name of whatever the player clicked, but I have no idea where to start.

#2

Like as a UI object or in the workspace?

Look into localplayer:GetMouse() if you mean getting what part a player touched in the workspace.

#3

tool activated connection, then use the players mouse and get the Target of it

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

local LocalPlayer = Players.LocalPlayer;
local Mouse = LocalPlayer:GetMouse()

Tool.Activated:Connect(function()
print(Mouse.Target.Name)
end)

This is purely an example based off of what you said, and is not clean

If you want just it, use what @Ihaveash0rtname just said.

If, in your game, you need something more, like “I don’t want to print the name of certain parts”, then you should do:

local player = game:GetService("Players").LocalPlayer
local camera = workspace.CurrentCamera
local UIS = game:GetService("UserInputService")

local tool = player:WaitForChild("Backpack"):WaitForChild("Tool")

local UnraycastableParts = workspace:WaitForChild("InvisibleWalls") -- only a example

local ClickRayParams = RaycastParams.new()
ClickRayParams.FilterType = Enum.RaycastFilterType.Exclude
ClickRayParams.FilterDescendantsInstances = {UnraycastableParts}

local function CastRayFromMouse(params)

    local mousePosition = UIS:GetMouseLocation()
    
    local ray = camera:ViewportPointToRay(mousePosition.X, mousePosition.Y)

    local result = workspace:Raycast(ray.Origin, ray.Direction * 1000, params)

    return result
end

tool.Activated:Connect(function()

        local result = CastRayFromMouse(ClickRayParams)

        if result and result.Instance then
            print(result.Instance.Name)
        else
            print("Clicked on empty space")
        end

end)

It is a bigger code but it’s better than LocalPlayer:GetMouse() because you can customize more easily what you want or not want to be findable in your raycast.
