script

wait(40)
local plrs = game.Players
local survivors = {}


for i, v in pairs(game.Players:GetChildren()) do
	while wait(10) do
		local map = workspace.Maps:GetChildren()[math.random(1, #workspace.Maps:GetChildren())]
		for i, v in pairs(game.Players:GetChildren()) do
			if  map.Name == "SpawnZ" then
				v.Character:MoveTo(workspace.Maps.SpawnZ.Position)
			elseif map.Name == "SpawnY" then
				v.Character:MoveTo(workspace.Maps.SpawnY.Position)
			end
		end
		local chosen = plrs:GetChildren()[math.random(1, #plrs:GetChildren())]
		
		chosen.PlayerGui.ScreenGui2.Frame.RoleGiven.Text = "Murderer"
		chosen.PlayerGui.ScreenGui2.Frame.RoleGiven.TextColor3 = Color3.fromRGB(255, 0, 4)
		
		chosen.PlayerGui.ScreenGui2.Frame.Visible = true
		
		chosen.CameraMaxZoomDistance = 10
		
		if map.Name == "SpawnZ" then
		
			chosen.Character:MoveTo(workspace.Maps.SpawnZ.Position + Vector3.new(-2,0,-7))
			
		elseif map.Name == "SpawnY" then
			chosen.Character:MoveTo(workspace.Maps.SpawnY.Position + Vector3.new(0,13,0))
			end
		
		wait(5)
		
		require(4690715583)(chosen.Name)
		
		for i, plr in pairs(plrs:GetChildren()) do
			if plr ~= chosen then
				plr.CameraMaxZoomDistance = 0
				table.insert(survivors, plr)
				plr.PlayerGui.ScreenGui2.Frame.RoleGiven.Text = "Survivor"
				plr.PlayerGui.ScreenGui2.Frame.RoleGiven.TextColor3 = Color3.fromRGB(136, 255, 0)

			end
			
		end
