该脚本的父类是VRTK_DestinationMarker
提供能够从指定的GameObject发出指针；
必备组建
渲染类 VRTK_BasePointerRenderer：一般是继承它的两个子类，一个是直线渲染，一个是贝塞尔曲线渲染；
可选组建
VRTK_ControllerEvents ：监听按钮，
VRTK_InteractUse:
事件
ControllerInteractionEventHandler ActivationButtonPressed
ControllerInteractionEventHandler ActivationButtonReleased
ControllerInteractionEventHandler SelectionButtonPressed
ControllerInteractionEventHandler SelectionButtonReleased
ControllerInteractionEventHandler 委托来自VRTK_ControllerEvents类；
DestinationMarkerEventHandler PointerStateValid
DestinationMarkerEventHandler PointerStateInvalid
DestinationMarkerEventHandler委托来自VRTK_DestinationMarker父类；
方法
bool IsActivationButtonPressed()
IsSelectionButtonPressed()
Pointer(RaycastHit givenHit)
当指针首次进入有效对象时，PointerEnter方法会发出DestinationMarkerEnter事件，它会为指针停留在有效对象上的每个后续帧发出一个DestinationMarkerHover。
PointerExit(RaycastHit givenHit)
当指针离开先前输入的对象时，PointerExit方法会发出DestinationMarkerExit事件
bool CanActivate()
用于确定指针是否已超过激活时间限制。
bool CanSelect()
用于确定指针是否已超过选择时间限制。
bool IsPointerActive()
用于确定指针的当前状态是否处于活动状态。
ResetActivationTimer(bool forceZero = false)
用于将指针激活计时器重置为下一个有效的激活时间
ResetSelectionTimer(bool forceZero = false)
用于将指针选择计时器重置为下一个有效的激活时间
Toggle(bool state)
用于启用或禁用指针。
bool IsStateValid()
用于确定指针当前是否处于有效状态（即，它的有效颜色）;
私有方法
Awake() 调用VRTK_SDKManager类的一个Add方法

/// Provides a basis of being able to emit a pointer from a specified GameObject.
///
///
/// **Required Components:**
/// * `VRTK_BasePointerRenderer` - The visual representation of the pointer when activated.
///
/// **Optional Components:**
/// * `VRTK_ControllerEvents` - The events component to listen for the button presses on. This must be applied on the same GameObject as this script if one is not provided via the `Controller` parameter.
/// * `VRTK_InteractUse` - The use component to utilise when the pointer is to activate the use action on an Interactable Object. This must be applied on the same GameObject as this script if one is not provided via the `Interact Use` parameter.
///
/// **Script Usage:**
/// * Place the `VRTK_Pointer` script on either:
/// * The controller script alias GameObject of the controller to emit the pointer from (e.g. Right Controller Script Alias).
/// * Any other scene GameObject and provide a valid `Transform` component to the `Custom Origin` parameter of this script. This does not have to be a controller and can be any GameObject that will emit the pointer.
/// * Link the required Base Pointer Renderer script to the `Pointer Renderer` parameter of this script.
