SOLVED! ANSWER: IM STUPID LOL Why dose this only work in studio, and not in the actual game?

So Im makeing a game called SkyWars and well the BreakTool works whenever you test it in studio... but it dose't when you save and play the actuial game.

This has happened to me alot... not just in this game.

well heres the script inside my BreakTool.

bin = script.Parent
local pack = bin.Parent
local player = pack.Parent

function onButton1Down(mouse)
    local hit = mouse.Target
    if (hit == nil) then return end
        if (hit.Block ~= nil) then -- dont worry about all this. hit.Block  dose exist (Theres a value called Block in hit)

            local block = game.Lighting.PlaceBlock:Clone() -- or about all this
            block.Parent = game.Players.LocalPlayer.Backpack -- or this
            block.Name = ""..hit.Name.."" -- or this. It works.

            hit:remove()
        end
    end



function onSelected(mouse)
    print("Action Tool Selected")
    mouse.Icon = "rbxasset://textures\\GunCursor.png"
    mouse.Button1Down:connect(function() onButton1Down(mouse) end)
end

bin.Selected:connect(onSelected)
