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)
