How do I use a table to randomize teleports CFrame?
I was testing a teleport where when you touched a part outside of the Lobby, it would teleport you back into the lobby. There was this error, here is my code and the error: Error:
22:25:09.867 - Workspace.Workspace.Sea.Script:12: bad argument #2 to 'random' (interval is empty) 22:25:09.868 - Stack Begin 22:25:09.869 - Script 'Workspace.Sea.Script', Line 12 22:25:09.869 - Stack End
Code:
script.Parent.Touched:Connect(function(hit)
local Humanoid = hit:FindFirstChild("Humanoid")
if Humanoid ~= nil then
wait()
else
print("Humanoid touched "..script.Parent.Name..".")
local rootPart = hit:FindFirstChild("HumanoidRootPart")
local spawns = {
spawn1 = game.Workspace.lobbySpawn1.CFrame,
spawn2 = game.Workspace.lobbySpawn2.CFrame
}
rootPart.CFrame = spawns[math.random(1,#spawns)]
local Success = "successTeleport"
end
end)
Thank you, I hope to recieve an answer.

you are using the length operator '#' to get the length of the table, hovever, this only works on tables that use regular number keys (1,2,3,4,etc) not string keys as shown in the example ("spawn1","spawn2",etc), so the '#' returns 0 because no number keyed items were found, this caused the maximum parameter for math.random() to be less than the minimum (1=1,#spawns=0) so you got an error relating to math.random
the solutions:
solution 1:
use a table that uses number keys
local spawns = {
game.Workspace.lobbySpawn1.CFrame,
game.Workspace.lobbySpawn2.CFrame
}
solution 2:
us a function to get its length including string keys
function GetLength(t)
local final = 0
for _,v in pairs(t) do final = final + 1 end
return final
end
rootPart.CFrame = spawns[math.random(1,GetLength(spawns))]
