Roblox anti-fall void reset script

-- Anti-fall: if a player drops below VOID_HEIGHT, they respawn.

local VOID_HEIGHT = -100     -- the Y height under your map. Pick a number lower than the lowest part.
local CHECK_EVERY = 0.5      -- seconds between checks

local Players = game:GetService("Players")

-- Roblox deletes anything below this height anyway (default -500).
-- Making sure our line is above it:
if VOID_HEIGHT <= workspace.FallenPartsDestroyHeight then
	warn("VOID_HEIGHT should be higher than workspace.FallenPartsDestroyHeight")
end

while true do
	for _, player in Players:GetPlayers() do
		local character = player.Character
		local humanoid = character and character:FindFirstChildOfClass("Humanoid")
		local root = character and character:FindFirstChild("HumanoidRootPart")

		if humanoid and root and humanoid.Health > 0 and root.Position.Y < VOID_HEIGHT then
			humanoid.Health = 0   -- the player respawns at their spawn or checkpoint
		end
	end
	task.wait(CHECK_EVERY)
