unity VR凝視gaze

VRヘッドをつけて、物体を見つめていると進捗バーがあり、完成を待つとクールなテクニックができます.
多くのVRのSDKにもこのスキルがあり、その原理は視線で探知し、下にコードを貼ることです
新しいスクリプトの名前はGazeControllerです.

GazeItemスクリプトには3つのインタラクションがあり、GazeInメソッドとGazeOut、GazeFireがあります.具体的な実現は異なる需要を見る.
 
 
 
物体と対話する必要がある場合は、次のインタフェースを使用します.

interface IRayInteractor
{

    /// 

    ///         
    /// 
    GameObject TempObj
    {
        get;

    }
    /// 

    ///                  
    /// 
    float NeedStayTime
    {
        get
        ;
        set;
    }
    /// 

    ///      
    /// 
    float StayTime { get; }

    /// 

    ///     
    /// 
    ///        
    void OnRayEnter(GameObject temp);

    /// 

    ///     
    /// 
    void OnRayExit();
    /// 

    ///     
    /// 
    void OnRayStay();
}
