Check if a tween is active

[theRealProHacker]

Is there a possibility to check whether a tween is active or not? Do I have to do it with :oncomplete ? Or can I manually check it if I store the tween as a variable like this:

myTween=flux.to(self, 4, {x=300})
...
if myTween:isActive() then
...
end

I'm not a contributor at all, but examining the source code we can see flux:to() wraps flux:add() which assigns the object and it's tween to a table in the flux instance, as well as the flux instance itself. These are later removed during flux:remove() which is called automatically by tween:stop().

I haven't tested this myself yet, but with this in mind, flux[obj][tween] == true should be sufficient to check if a tween exists (i.e. is a valid handle) and is actively being controlled by this instance of flux.
