Hello guys,
I am pretty new to corona sdk and development in general, but I managed to get a quick demo of my game idea quickly - I was and I still am surprised about this fact 
Since I want a game with at least a starting screen, a game screen and a game ended scene, I needed to take a look at storyboards and scenes. I found the very useful template for storyboards and scenes in the forum and took this template as a starting point to copy all my working code from one single lua file to a game scene lua file as a storyboard.
As I thought I placed all my code in the right positions and the game does still work BUT what is not working anymore is the collision detection and I can not figure out why this is like that.
So I thought I post my problem to the forum and hopefully some of you guys could help me out on that.
Attached you find my code and I would be very greatful if you could take a look at it and give me a hint and/or an helping hand.
Thanks so much and best regards,
Johannes
