how do i randomize spawn points?

i have like 6 spawn locations but when i tried i spawned at the same one everytime, how do i make it at random?

I don't think that there is a way to choose what SpawnLocation you spawn at without making your own parts and script. For instance, if I were to want randomized spawns I would add regular Parts into the workspace and make sure they are anchored with CanCollide set to false and a transparency of 0. I would put all of those parts in a folder named "Spawns" and place them where I want to spawn the player. The script would look as follows.

local spawns = workspace:WaitForChild("Spawns"):GetChildren() --making a table

local function spawnPlayer(hrp, spawnPoint)
	wait()
	hrp.CFrame = spawnPoint.CFrame + Vector3.new(0,3,0)
end

game.Players.PlayerAdded:Connect(function(plr) -- every time a player joins this will run
	plr.CharacterAdded:Connect(function(char) -- every time the player spawns in this will run
		local chosenSpawn = math.random(1, #spawns) -- #spawns is equal to the number of values stored in the table we created on the first line (in your case, 6)
		spawnPlayer(char.HumanoidRootPart, spawns[chosenSpawn])
	end)
end)

This works in my studio when I test it, let me know if anything goes wrong for you or if you have any questions. Hope I helped!
