How can you make it so that when you touch a brick it gives you an item?

That's easy and by the way scripting helpers.org is not a request site

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)

        game.ReplicatedStorage.Lemonaid:Clone().Parent = player.Backpack -- Put lemonaid as your axe name

        script.Disabled = true

        wait(2)

        script.Disabled = false
    end
end)

Put your tool in ReplicatedStorage, insert a script into the part and type this in. I added a debounce because I suppose it's a multiplayer game so many people that play will get the tool when they reach that part.

db = false -- debounce

local tool = game.ReplicatedStorage.ClassicSword -- change ClassicSword to your tool name

script.Parent.Touched:Connect(function(hit) -- when the part is hit
    if hit.Parent:FindFirstChild("Humanoid")then -- if the part was hit by a humanoid then
        if db == false then -- if debounce is false then
            db = true -- debounce is true
            local player = game.Players:GetPlayerFromCharacter(hit.Parent) -- the player
            local backpack = player:WaitForChild("Backpack") -- player's backpack
            tool:Clone().Parent = backpack -- puts the tool in the player's backpack. Added tool:CLone() before the .Parent = backpack because since many people will get that tool [i suppose] it needs to clone so it doesn't just work once.
            wait(5) -- the delay before you can get the tool again
            db = false -- debounce = false
        end -- ends
    end
end)

Hope this helped! If you want to add indicators like color changes or something like that respond to me and i'll do it for you if you don't know.

Take care!
