Question

我意识到有数百页与此错误有关。然而，我已经查看了很多这些并且无法找到与我的特定问题相关的内容，所以如果这是一个重复的线程，我会道歉。我试图修改由Unity提供的2D相机脚本，以选择其“目标”（它遵循的游戏对象）到用户选择的任何字符。我是C＃的新手所以我真的不太清楚如何处理这个错误。我发布了整个代码以防万一，但错误很可能在前10行左右找到

using UnityEngine;

namespace UnitySampleAssets._2D
{

    public class Camera2DFollow : MonoBehaviour
    {
        private string character = PlayerPrefs.GetString("Character")
        public Transform target = Transform.Find(character);
        public float damping = 1;
        public float lookAheadFactor = 3;
        public float lookAheadReturnSpeed = 0.5f;
        public float lookAheadMoveThreshold = 0.1f;

        private float offsetZ;
        private Vector3 lastTargetPosition;
        private Vector3 currentVelocity;
        private Vector3 lookAheadPos;

        // Use this for initialization
        private void Start()
        {
            lastTargetPosition = target.position;
            offsetZ = (transform.position - target.position).z;
            transform.parent = null;
        }

        // Update is called once per frame
        private void Update()
        {

            // only update lookahead pos if accelerating or changed direction
            float xMoveDelta = (target.position - lastTargetPosition).x;

            bool updateLookAheadTarget = Mathf.Abs(xMoveDelta) >                    lookAheadMoveThreshold;

            if (updateLookAheadTarget)
            {
                lookAheadPos =       lookAheadFactor*Vector3.right*Mathf.Sign(xMoveDelta);
            }
            else
            {
                lookAheadPos = Vector3.MoveTowards(lookAheadPos, Vector3.zero, Time.deltaTime*lookAheadReturnSpeed);
            }

            Vector3 aheadTargetPos = target.position + lookAheadPos + Vector3.forward*offsetZ;
            Vector3 newPos = Vector3.SmoothDamp(transform.position, aheadTargetPos, ref currentVelocity, damping);

            transform.position = newPos;

            lastTargetPosition = target.position;
        }
    }
}

Answer 1

您无法使用其他变量

初始化变量

driver.findElements(By.cssSelector("input[required]"))

而是将其放在private string character = PlayerPrefs.GetString("Character") public Transform target = Transform.Find(character); // <---- Trying to access 'character' which is a variable方法

中

Start()

Unity错误CS0236：字段初始值设定项无法引用非静态字段，方法或属性`UnitySampleAssets._2D.Camera2DFollow.Characters'
