How to learn to use something that I dont have??? OMG. I know the basics. Variables etc. But I need a little help on collision. If you cant help me dont answer I will ask to someone else...Anyway it's so funny that how envious you are HAHAHAHA. If I buy something I try to buy the best thats why I chose a7pro. It's pointless to buy a5 than in the future a7. It's easier to buy the best so you dont have to spend more money to both. And from now on "Ignore on" for all envious people. Only write if you want to help...
