Touch Controls help

Can someone help me add touch controls to my game while not drastically changing the gameplay?If it needs to be changed,you can do that.I'm really worried i'll break the game if I add them myself,so i'm asking someone to help me do it.Just reply me the touch control version.I'll put you in the credits under whatever you want to go by.

..just to check something ..you have the same events at all Event Sheets ?

( Event sheet 1=Event sheet 2 =Event sheet 3....)

and Player unit control1=Player unit control2=Player unit control3

the bottom event(the layout the flag takes out to) is different,also remember to reply the touch control version when it's done
