How do I make a player automatically hold an item upon grabbing it?

When I touch a tool off the ground and pick it up it's only in my inventory, it's never held automatically.

How do I make the Tool held automatically without removing the backpack?

You could try a ChildAdded event on the Backpack, it would look something like this.

local player = game.Players.LocalPlayer
local char = player.CharacterAdded:wait() -- Waits for the character

player.Backpack.ChildAdded:connect(function(child) -- Child added event returns the child
	char.Humanoid:EquipTool(child) -- Equip the child that was returned
end)

I don't use those often so let me know if this works, and if anyone knows a better way, let us know.

I fixed it by deleting a script that ruined it. Thanks for the help, it's solved.
