# Touch

### Description

This collection of [OverNode](/over-sdk-manual/over-visual-scripting-legacy/visual-scripting-essentials/overnode.md)s represents all the nodes that interact with common interactions in Mobile devices, such as finger pressing. 

#### Touch Node

The main element of this system consists of a Touch Node, responsible to fire its execution on detecting a specific Touch event.

Each Touch Node must refer to a specific `Target` GameObject, accordingly equipped with a Unity [Collider](https://docs.unity3d.com/ScriptReference/Collider.html) Component. Once a touch is detected and the Target is hit by the touch, the following nodes will be executed.

A `Touch Mode` parameter can be selected in order to further customize the execution of the node, specifically:

<table><thead><tr><th width="204">Name</th><th>Description</th></tr></thead><tbody><tr><td>Click</td><td>Sets the node to be executed when a click is detected.</td></tr><tr><td>Press</td><td>Sets the node to be executed when a finger press is detected.</td></tr><tr><td>Long Press</td><td>Sets the node to be executed when a finger pressing for more than 0.5s is detected.</td></tr></tbody></table>

The Node also exposes some parameters:

<table><thead><tr><th width="205.7659040188865">Name</th><th width="194.3279424240331">Type</th><th width="340.1572968009442">Description</th></tr></thead><tbody><tr><td>Other</td><td><a href="https://docs.unity3d.com/ScriptReference/Collider.html">Collider</a></td><td>A reference of the input Unity Collider Component of the object touched</td></tr></tbody></table>

#### OverTouchListener

In order for the Node system to communicate to the Unity Runtime environment, a OverTouchListener component must be associated to the Target GameObject.&#x20;

Its main function is to provide a bridge between the node system and the UnityEngine event system, which handles touch events in automatic.
