如何以紙板方向移動播放器？

Question

我已經在我的團結項目中設置了Google vr sdk，並且它可以完美地移動相機。但是，我如何使用vr方向來控制玩家？例如，當我將頭轉向左側或右側時，玩家向左或向右移動。

在我的代碼，我只知道，從鍵盤獲取輸入：

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

這是一個腳本，我經常使用移動播放器相機的方向。它使用紙板磁鐵按鈕觸發行走。你可以改變它到任何你想要的。

// 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

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("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.")]

     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); 
     } 
    } 
}
