title: Alternative to GetMouseDown for multiple touches
body: <p>I have a game I am making in Unity3D, for Android, in which the player has two arrow buttons to press which control the characters movement left and right. If I click on the left arrow, I have to remove my finger to then press the right arrow and move right, as GetMouseDown does not recognise that these are two seperate touches.</p>
  
  <p>Is there a better alternative to GetMouseDown that will recognise the most recently clicked arrow key for movement, so that I do not have to unclick the first arrow button, which is not very ergonomic </p>
