Hello, I implemented a dynamic hud manager in c++ whose public member functions are bound to lua. From a lua interface, the user is able to create hud elements, and hud element groups; in addition controls are given to disable both groups and individual hud elements. This logic works fine, however a problem comes in when trying to enable an element or group that is already in the scene--two copies now exist. It seems like quite a bit of overhead to track whether or not each individual group and element is in the scene; is there some way to remove -all- children that share the same reference pointer? By executing "removeChild( ptr )", it only removes the most recent addition.
Thanks in advance, Dusten
