How does input work when exporting to Android?

Question

I know I must add Android sdk , but my question is this :

If I make a game that works with the mouse, for example a puzzle game, then I output my game to Android, do I have to rewrite it to work with the touch screen?

Answer 1

With Unity, the mouse input will work like a touch input on android, automatically.

Alternatively, you can look at the Input.touches class to handle multiple touches.
