"I want to make it so if you click on a part with ClickDetector, the player will get teleported to (0, 3, 0), and to prevent spam, you have to wait 1 second, and I want clear instructions on how to do it."

Sure, here's how you can do it:

1. First, you need to insert a part into your workspace. You can do this in the Roblox Studio by going to the "Model" tab and clicking on "PrimaryPart", then select the part in your workspace.

2. Once you have your part, you need to add a ClickDetector to it. You can do this by selecting the part, going to the "Model" tab, and clicking on "PrimaryPart". Then, in the Explorer window, right-click on the part, hover over "Insert Object", and click on "ClickDetector".

3. Now you need to add a script to the part. Right-click on the part again, hover over "Insert Object", and click on "Script".

4. In the script, you can add the following code:

--lua
local part = script.Parent
local clickDetector = part:FindFirstChild("ClickDetector")
local debounce = false -- This is to prevent spam

local function teleport(player)
	if debounce == false then
		debounce = true -- The player has clicked and must wait
		player.Character.HumanoidRootPart.CFrame = CFrame.new(0, 3, 0) -- Teleport the player
		wait(1) -- Wait for 1 second
		debounce = false -- The player can click again
	end
end

clickDetector.MouseClick:Connect(teleport)
--

This script will teleport the player to the coordinates (0, 3, 0) when they click on the part. The debounce variable is used to prevent the player from spamming the click action. When the player clicks, debounce is set to true, and they must wait for 1 second before they can click again.
