How do you make your cursor dissapear?

I'm making an FPS (so original, right?) and want the mouse cursor to disappear as soon as you join the game. Considering that PlayerMouse isn't an option, and I don't want to use HopperBins (manually selecting? eww), my only choice is a tool. I can get it to select and change the icon fine, but the problem is if I delete the tool (dont want tool to show, or player be able to deselect it), obviously the cursor resets.

I've read some stuff on forums that there's a way around this, but I can't find it. Basically: Is there a way to automatically change the player's cursor?

To remove the tool gui :

game.StarterGui:SetCoreGuiEnabled("Backpack", false)

Here is about the mouse icon :

This should work. Also, the decals i used are just blank images that make the cursor look blank.

0~~~~~~~~~~~~~~~~~ 1 ~~~~~~~~~~~~~~~~~ bin = script.Parent 02 normel = "http://www.roblox.com/asset/?id=52574777" -- some random blank images. 03 friendly = "http://www.roblox.com/asset/?id=52574777" 04 enemy = "http://www.roblox.com/asset/?id=52574777" 05 function Run(mouse) 06 mouse.Icon = normel 07 local hit = mouse.Target 08 if (hit == nil) then return end 09 h = hit.Parent:FindFirstChild("Humanoid") 10 if h ~= nil then 11 torso = hit.Parent.Torso 12 if torso ~= nil then 13 if h.Health > 0 then 14 if (torso.BrickColor == bin.Parent.Torso.BrickColor) then 15 mouse.Icon = friendly 16 elseif torso.BrickColor ~= bin.Parent.Torso.BrickColor then 17 mouse.Icon = enemy 18 end 19 end 20 end 21
22 end 23 end 24 script.Parent.Equipped:connect(on)

function on(mouse)
        while true do
        wait()
	Run(mouse)
        end
end



script.Parent.Equipped:connect(on)

If this doesn't work, please tell me. It should work.
