Difference between a phone and a pc 2D game

So,i created a game for PC.If i want to create a game for iOS or Android what should i do ?
I mean,i saw that i need to download a module for iOS/Android but what do i do about swiping/touching the screen with your finger ? on pc you use keys and clicks,how do you swipe/touch on a phone ?
Also,is there other functions that are different than creating a game for PC ?

 

There's a bunch of stuff and there's been a lot of discussion and documentation about it. Generally though things are much the same. A left mouse click will translate as a 'tap' automatically. There are obviously not keyboard keys as such. You would need to implement swipe support in other ways - input modules, mobile user input tools, etc. see the App Store.
