What is the best way of monitoring obj.resting?

[Nedok1]

The sort version:
I want to generate an event when resting == true for a number of dices.

What are the best way of implementing it?
Is it possible to do without having an onUpdate function?

--This makes a blank table used later
ref_diceWatched = {}

--Watch for randomized dice (hitting R on them)
function onObjectRandomize(object, player_color)
    if object.tag=="Dice" and ref_diceWatched[object]==nil then
        ref_diceWatched[object] = true
        watchDieRoll(object, player_color)
    end
end

--Watch for dropped dice (physically rolled) (possible cheat warning)
function onObjectDropped(player_color, object)
    if object.tag == "Dice" and ref_diceWatched[object]==nil then
        ref_diceWatched[object] = true
        watchDieRoll(object, player_color)
    end
end

--Function which runs a coroutine to watch the dice
function watchDieRoll(die, color)
    function watchDieRoll_routine()
        while die.resting == false do
            coroutine.yield(0)
        end



        ref_diceWatched[die] = nil
        return 1
    end
    startLuaCoroutine(Global, "watchDieRoll_routine")
end

He is one I wrote a while back. Those 3 empty lines in the watchDieRoll function are where you would insert any code you want to have ru nonce the dice come to rest.

It might work for me... but it doesn't seem like it handels when a dice get velocity form sources other than a player.
Could that not pose a problem when rolling multiple dice at once?
