 # Input
 
-The `Game` class has a vast number of methods for handling touch controls, to use it, just override the method you want to use, and that method will start receiving events, below there is the whole list of available methods:

-Since many detectors conflict with each other, (for example, you can't register both Vertical and Horizontal drags) by default only the __tap detectors__ are already registered.
+Many of these detectors can conflict with each other, for example, you can't register both Vertical and Horizontal drags, so not all of then can be used together.
 
-To change that behaviour, you can override methods that enable or disable that gesutre detector for the game, for example, to enable vertical drag detectors, you should override the `useVerticalDragDetectors` to return `true`, all the other detectors have equivalent methods and follow the same logic.
-
-All those methods are basically a mirror from the callbacks available on the [GestureDetector widget](https://api.flutter.dev/flutter/widgets/GestureDetector-class.html), you can also read more about Flutter's gestures [here](https://api.flutter.dev/flutter/gestures/gestures-library.html).
