Wait 100 seconds, but on an event, skips the time?

How would I do that? Like this; A (round) script waits 100 seconds, but also there is a InGame boolvalue inside each player, and it constantly checks if only 1 person has that boolvalue, or none, and if either of those are true, skips the rest of the time? I have no idea how I would do this.

You might need 2 separate scripts, one for waiting 100 seconds, and one for checking if anyone has the boolvalue. This is for timing:

while true do
	if Workspace.Running == true then
		for i = 1, 100 do
			Workspace.Time.Value = i  --Time is a NumberValue. You can use this to have a timer on a GUI or something.
			if Workspace.Running == false then --Running is a BoolValue in the Workspace.
				break end
			wait(1)
		end
		Workspace.Running == false
		else wait(1)  --So an infinite loop doesn't occur.
	end
end

As you can see, I made it so that you can easily add a timer. For checking if the BoolValue in the players is true, put this is a separate script.

while wait(1) do --No Infinite Loops!
	if Workspace.Running == true then
		for i, v in pairs(game.Players:GetChildren()) do --v in pairs is awesome
			Value = v.Character:FindFirstChild("BoolValue") --Making sure there is a BoolValue
			if Value.Value == true then
				Workspace.Running == false
			end
		end
	end
end

These should work! Just make sure you have a BoolValue called "Running" and a NumberValue called "Time" in the Workspace. Comment if you have any issues!

This code sums up how it would be organized... Change your conditions to whatever.

Untested, but just an example.

while boolValue == false do
     if game.Players <= 1 then
          wait()
     else
          boolValue = true
end


if condition then
     wait(100)
elseif boolValue then
      --code
end
