ボールボードの向きでプレーヤーを移動するにはどうすればよいですか？

Question

私は、私のユニティプロジェクトでgoogle vr sdkをセットアップしました。カメラを動かすと完全に動作します。しかし、どのようにプレイヤーをコントロールするためにvrの向きを使うことができますか？ たとえば、頭を左右に回すと、プレーヤーは左右に移動します。私のコードで

、私はちょうど、キーボードからの入力を取得する知っている：

float moveHorizontal = Input.GetAxis("Horizontal"); 
float moveVertical = Input.GetAxis("Vertical"); 
Vector3 movement = new Vector3(moveHorizontal, moveVertical + motion_cont.getVertical(), 1f); 
rb.velocity = movement * motion_cont.getSpeed(); 

Answer 1

これは私が多くの場合、カメラの方向にプレーヤーを移動するために使用するスクリプトです。ダンボールのマグネットボタンを使用して歩行をトリガーします。あなたはそれをあなたが望むものに変えることができます。

// This script moves your player automatically in the direction he is looking at. You can 
// activate the autowalk function by pull the cardboard trigger, by define a threshold angle 
// or combine both by selecting both of these options. 
// The threshold is an value in degree between 0° and 90°. So for example the threshold is 
// 30°, the player will move when he is looking 31° down to the bottom and he will not move 
// when the player is looking 29° down to the bottom. This script can easally be configured 
// in the Unity Inspector.Attach this Script to your CardboardMain-GameObject. If you 
// haven't the Cardboard Unity SDK, download it from https://developers.google.com/cardboard/unity/download 

using UnityEngine; 
using System.Collections; 

public class Autowalk : MonoBehaviour 
{ 
    private const int RIGHT_ANGLE = 90; 

    // This variable determinates if the player will move or not 
    private bool isWalking = false; 

    CardboardHead head = null; 

    //This is the variable for the player speed 
    [Tooltip("With this speed the player will move.")] 
    public float speed;

    [Tooltip("This has to be an angle from 0° to 90°")] 
    public double thresholdAngle; 

    [Tooltip("Activate this Checkbox if you want to freeze the y-coordiante for the player. " + 
      "For example in the case of you have no collider attached to your CardboardMain-GameObject" + 
      "and you want to stay in a fixed level.")]

     { 
      isWalking = false; 
     } 

     // Walk when the Cardboard trigger is used and the player looks down below the threshold angle 
     if (walkWhenLookDown && walkWhenTriggered && !isWalking && 
      head.transform.eulerAngles.x >= thresholdAngle && 
      Cardboard.SDK.Triggered &&

      isWalking = false;

     if (isWalking) 
     { 
      Vector3 direction = new Vector3(head.transform.forward.x, 0, head.transform.forward.z).normalized * speed * Time.deltaTime; 
      Quaternion rotation = Quaternion.Euler(new Vector3(0, -transform.rotation.eulerAngles.y, 0)); 
      transform.Translate(rotation * direction); 
     } 

     if(freezeYPosition) 
     { 
      transform.position = new Vector3(transform.position.x, yOffset, transform.position.z); 
     } 
    }
