TouchScreenButton
=================

**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Button for touch screen devices for gameplay use.

.. rst-class:: classref-introduction-group

Description
-----------

TouchScreenButton allows you to create on-screen buttons for touch devices. It's intended for gameplay use, such as a unit you have to touch to move. Unlike :ref:`Button<class_Button>`, TouchScreenButton supports multitouch out of the box. Several TouchScreenButtons can be pressed at the same time with touch input.

This node inherits from :ref:`Node2D<class_Node2D>`. Unlike with :ref:`Control<class_Control>` nodes, you cannot set anchors on it. If you want to create menus or user interfaces, you may want to use :ref:`Button<class_Button>` nodes instead. To make button nodes react to touch events, you can enable :ref:`ProjectSettings.input_devices/pointing/emulate_mouse_from_touch<class_ProjectSettings_property_input_devices/pointing/emulate_mouse_from_touch>` in the Project Settings.

You can configure TouchScreenButton to be visible only on touch devices, helping you develop your game both for desktop and mobile devices.
