Hi Renata, > TypeError: Error # 2007: Parameter hitTestObject must not be null.
The argument to hitTestObject() is 'mouse'. You get the error because the 'mouse' argument to hitTestObject() is null. Since mouse is constructed in function iniciarJogo(), my guess is that iniciarJogo() never gets called. An easy fix would be to call iniciarJogo from the constructor of the Bolhas class, like this: public function Bolhas() { iniciarJogo(); } -Gerry _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
