		<h1>[name]</h1>

		<p class="desc">
			This class is an alternative implementation of [page:FlyControls].
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { FirstPersonControls } from 'three/addons/controls/FirstPersonControls.js';
		</code>

		<h2>Examples</h2>

		<p>[example:webgl_geometry_terrain webgl / geometry / terrain ]</p>

		<h2>Constructor</h2>

		<h3>[name]( [param:Camera object], [param:HTMLDOMElement domElement] )</h3>
		
			<p>
				[page:Camera object]: The camera to be controlled.
			</p>
			<p>
				[page:HTMLDOMElement domElement]: The HTML element used for event listeners. (optional)
			</p>
			<p>
				Creates a new instance of [name].
			</p>
		

		<h2>Properties</h2>

		<h3>[property:Boolean activeLook]</h3>
		<p>
			Whether or not it's possible to look around. Default is `true`.
		</p>

		<h3>[property:Boolean autoForward]</h3>
		<p>
			Whether or not the camera is automatically moved forward. Default is `false`.
		</p>

		<h3>[property:Boolean constrainVertical]</h3>
		<p>
			Whether or not looking around is vertically constrained by [[page:.verticalMin], [page:.verticalMax]]. Default is `false`.
		</p>

		<h3>[property:Number heightCoef]</h3>
		<p>
			Determines how much faster the camera moves when it's y-component is near [page:.heightMax]. Default is *1*.
		</p>

		<h3>[property:Number heightMax]</h3>
		<p>
			Upper camera height limit used for movement speed adjustment. Default is *1*.
		</p>

		<h3>[property:Number heightMin]</h3>
		<p>
			Lower camera height limit used for movement speed adjustment. Default is *0*.
		</p>

		<h3>[property:Boolean heightSpeed]</h3>
		<p>
			Whether or not the camera's height influences the forward movement speed. Default is `false`.
			Use the properties [page:.heightCoef], [page:.heightMin] and [page:.heightMax] for configuration.
		</p>

		<h3>[property:Boolean lookVertical]</h3>
		<p>
			Whether or not it's possible to vertically look around. Default is `true`.
		</p>

		<h3>[property:Number lookSpeed]</h3>
		<p>
			The look around speed. Default is `0.005`.
		</p>

		<h3>[property:Boolean mouseDragOn]</h3>
		<p>
			Whether or not the mouse is pressed down. Read-only property.
		</p>

		<h3>[property:Number movementSpeed]</h3>
		<p>
			The movement speed. Default is *1*.
		</p>

		<h3>[property:Number verticalMax]</h3>
		<p>
			How far you can vertically look around, upper limit. Range is 0 to Math.PI radians. Default is `Math.PI`.
		</p>

		<h3>[property:Number verticalMin]</h3>
		<p>
			How far you can vertically look around, lower limit. Range is 0 to Math.PI radians. Default is *0*.
		</p>

		<h2>Methods</h2>

		<h3>[method:undefined handleResize] ()</h3>
		<p>
			Should be called if the application window is resized.
		</p>

		<h3>[method:FirstPersonControls lookAt]( [param:Vector3 vector] )<br />
		[method:FirstPersonControls lookAt]( [param:Float x], [param:Float y], [param:Float z] )</h3>
		<p>
			<p>
				<p>
					vector - A vector representing the target position.
				</p>
				<p>
					Optionally, the x, y, z components of the world space position.
				</p>
			</p>
			<p>
				Ensures the controls orient the camera towards the defined target position.
			</p>
		</p>
