How to make parts turn visible/invisible when the player is holding a tool and hovering over it?

Asked by

Objective: Make a script that makes the npc's hitbox part visible when the player has the tool equipped and have their mouse on the hitbox.

Problem: The hitbox turns visible when hovered over but I don't know how to make the hitbox to go back to normal when the tool isn't equipped and when they aren't pointing at the hitbox.

In my game there is a folder in workspace named npcs and inside it are the npcs. Each npc has a part in them named hitbox which is what I'm trying to edit. This is a local script inside a tool's handle.

01player = game.Players.LocalPlayer
02handle = script.Parent
03tool = script.Parent.Parent
04 
05 
06tool.Equipped:connect(function(mouse)
07    while tool:IsDescendantOf(player.Character) do -- Loops while the tool is in the player's character (equipped)
08        wait(0.1)
09        ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - handle.CFrame.p).unit * 30)
10        -- Makes the rays
11        part = workspace:FindPartOnRay(ray, player.Character, false, true) 
12        -- finds the part
13        if part then -- checks if it found a part.
14            if part.Name == "Hitbox" and part:IsDescendantOf(workspace.NPCs) then
15            -- checks if the part is a hitbox and it is a descendant of the NPC folder.
16                part.Transparency = 0 -- Changes part transparency
17            else
18                print("Part Not Hitbox") -- If the part isn't a npc's hitbox
19            end
20        else
21            print("Not part") -- If the ray didn't get a part.
22        end
23    end

Hello, Adv3rtizement!

Use mouse.target to get the part mouse is pointing to =D, so don't need to use Rays(they're not really precise)

Using Ray(not precise)

01player = game.Players.LocalPlayer
02handle = script.Parent
03tool = script.Parent.Parent
04 
05local ChangedPart = nil
06 
07tool.Equipped:connect(function(mouse)
08    while tool:IsDescendantOf(player.Character) do -- Loops while the tool is in the player's character (equipped)
09        wait(0.1)
10        ray = Ray.new(tool.Handle.CFrame.p, (mouse.Hit.p - handle.CFrame.p).unit * 30)
11        -- Makes the rays
12        part = workspace:FindPartOnRay(ray, player.Character, false, true) 
13        -- finds the part
14        if part then -- checks if it found a part.
15            if ChangedPart then
16                ChangedPart.Transparency = 1 --Backs the transparency to 1
17                ChangedPart = nil
18            end
19            if part.Name == "Hitbox" and part:IsDescendantOf(workspace.NPCs) then
20            -- checks if the part is a hitbox and it is a descendant of the NPC folder.
21 
22        ChangedPart = part --Stores the part it's changing....
23 
24                part.Transparency = 0 -- Changes part transparency
25            else
26                print("Part Not Hitbox") -- If the part isn't a npc's hitbox
27            end
28        else
29        if ChangedPart then --Tests if had a part
30        ChangedPart.Transparency = 1 --Backs the transparency to 1
31        ChangedPart = nil
32       end
33            print("Not part") -- If the ray didn't get a part.
34        end
35    end
36 
37end)
38 
39tool.Unequipped:connect(function(mouse)
40    if ChangedPart then
41        wait(.1)
42        ChangedPart.Transparency = 1
43        ChangedPart = nil
44    end
