</div>
<div style="overflow:hidden;"><a name="GettingStarted"></a><h2>How do I get started?</h2><p>First you need to add the LeanTouch component to your scene:</p><div class="tip"><strong>METHOD 1</strong>&emsp;From your menu bar, select <strong>GameObject > Lean > Touch</strong>.</div><div class="tip"><strong>METHOD 2</strong>&emsp;Right click inside the Hierarchy window, and go to <strong>Lean > Touch</strong>.</div><div class="tip"><strong>METHOD 3</strong>&emsp;Create a new GameObject, and add the component <strong>Lean > Touch</strong>.</div><p>You should now see a new GameObject called <b>'LeanTouch'</b> with the LeanTouch component selected.</p><p>When you enter play mode, this component will automatically convert all mouse and touch input into an easy to use format.</p><p>Remember that scripts using Lean Touch only work when there is a LeanTouch component active in your scene, so make sure to add one to every scene (or carry it over with DontDestroyOnLoad).</p><div class="tip"><strong>NOTE</strong>&emsp; If you want to simulate multi finger gestures on desktop then click the <b>Add Simulator</b> button.</div><br><br></div><div style="overflow:hidden;"><a name="WithoutCode"></a><h2>How do I use Lean Touch without code?</h2><p>Lean Touch comes with many example components to do common tasks.</p><p>For example, if you want to spawn a prefab when a finger touches the screen, you can begin by making a new GameObject, and adding the <b>LeanSpawn</b> component.</p><p>Inside this component, you'll see it has the <b>Prefab</b> setting. You can browse or drag and drop your desired prefab here.</p><p>Next, you can add the LeanFingerTap component. Inside this component, you'll see it has the <b>OnFinger</b> event.</p><p>To link this event to the prefab spawning, you need to click the plus <b>+</b> button below where it says <b>List is Empty</b>, and in the bottom left box that says <b>None (Object)</b>, you need to drag and drop the LeanSpawn component you added earlier.</p><p>Next, you need to click the <b>No Function</b> dropdown, and select the <b>LeanSpawn > Dynamic LeanFinger > Spawn</b> function. You can now hit play, and tapping a finger (or clicking) on the screen will spawn your prefab.</p><p>There are many other components that work in similar ways that can be connected together using only the editor. To find out how these work, I recommend you browse through the demo scenes and look at the GameObjects to see what's going on.</p><br><br></div><div style="overflow:hidden;"><a name="WithCode"></a><h2>How do I use Lean Touch with C#?</h2><p>You can access all finger data from the <b>Lean.Touch.LeanTouch</b> class.</p><p>The easiest way to begin is by hooking into the static events it exposes.</p><p>For example, if you want to perform an action when a finger touches the screen, you can hook into the <b>Lean.Touch.LeanTouch.OnFingerDown</b> event. This event gets called every time a finger begins touching the screen, and gets passed a <b>Lean.Touch.LeanFinger</b> instance as a parameter. It's recommended you hook into these events from <b>OnEnable</b>, and unhook from <b>OnDisable</b>.</p><div class="code"><pre>public class MyCoolScript : MonoBehaviour<br>{<br> void OnEnable()<br> {<br> Lean.Touch.LeanTouch.OnFingerTap += HandleFingerTap;<br> }<br><br> void OnDisable()<br> {<br> Lean.Touch.LeanTouch.OnFingerTap -= HandleFingerTap;<br> }<br><br> void HandleFingerTap(Lean.Touch.LeanFinger finger)<br> {<br> Debug.Log("You just tapped the screen with finger " + finger.Index + " at " + finger.ScreenPosition);<br> }<br>}<br></pre></div><p>To see what other events are available, I recommend you read the <b>LeanTouch.cs</b>, script and its comments.</p><p>Another way to access finger data is to poll it directly from the <b>Lean.Touch.LeanTouch.Fingers</b> static list. This list stores all fingers that are currently touching the screen, and you can use this data at any time (e.g. Update) to quickly handle input.</p><div class="code"><pre>public class MyCoolScript : MonoBehaviour<br>{<br> void Update()<br> {<br> var fingers = Lean
