Game help - traps, cannons, screen focus

Hello all, i would like to know how i can get corona to randomly place “traps” along a area - my game is one where you try to get something as far as you can before your movement had stopped, or you hit a “trap” - for example, i would like spikes to be randomly placed to a user might hit one or may not. If you need me to explain more i will, and please bear in mind i’m just a 7th grader i’m sorry if it annoys any of you professionals.Also i have an error - my screen won’t go to the right once the guy has been shot out of the cannon and have the camera fixed on him - all it does is lets him fire out then he’s off screen. what should i do it does not scroll to the right either.

Thanks in advance,
