This is great great tutorial , I have ever seen,
I appriciate your effort !!!
I am working on a game.When I was started to develop this game.I have nothing to know about BB Java development and how to implement this to the game.But when i found your tutorial it becames quite simple to develop the game.

and now i have almost completed my game but there is a proble to add sound effect.
sound is working but we are trying to implement like :

When our application start music volume should be 100%
and when game starts music volume should be 50% and sound effects 100%
I have no idea about that.

Please help me and give me detail information for this.
