Hi,
Following some work with Magnus @ tumbleHead, please find a custom action check if a game Object is active. It works for Unity 4 only, as Unity 4 as new ways to check for ACtive states of a GameObject, in our case, it will check that the game object is active within the hierarchy ( as opposed to being self active, but maybe it's parent is inactive...)
