<div class="description">
Mouse and touch input handling. An instance of Mouse is available as <a href="Splat.Game.html#mouse">Splat.Game#mouse</a>.
The first touch will emulates a mouse press with button 0.
This means you can use the mouse (<a href="Mouse.html#isPressed">Mouse#isPressed</a>/<a href="Mouse.html#consumePressed">Mouse#consumePressed</a>) APIs and your game will work on touch screens (as long as you only need the left button.
A mouse press will emulate a touch if the device does not support touch.
This means you can use <a href="Mouse.html#touches">Mouse#touches</a>, and your game will still work on a PC with a mouse.
Also, if you call <a href="Mouse.html#consumePressed">Mouse#consumePressed</a> with button 0, it will add a `consumed:true` field to all current touches. This will help you prevent processing a touch multiple times.
