Post your game.h file (as text and within code markup tags).

Hello and welcome.

In addition to @mchinand, please think about a (short but) meaningful title for your threads. hey, does not help those who read the questions.

You probably will also need to paste the content of your game.h header file, we need to see the declaration of Game class (does it have Q_OBJECT macro?) and Game::spawnEnemy() method (is it marked as a slot?).
