意外符號CS1525變量名稱

Question

我已經更改了一些代碼以適合我的需要。儘管變量「dest」應該是一個局部變量（我認爲），爲什麼出現一個錯誤出現在爲dest分配一個值給dest的符號「dest'錯誤，以及我將如何解決它？ （這裏的鏈接：http://noobtuts.com/unity/2d-pacman-game）

using UnityEngine; 
using System.Collections; 

public class SepticSamMove : MonoBehaviour 
{ 
    public float speed = 0.4f; 
    Vector2 dest = Vector2.zero; 

    // Use this for initialization 
    void Start() 
    { 
     dest = transform.position; 
    } 

    // Update is called once per frame 
    void FixedUpdate() 
    { 
     //move closer to Destination 
     Vector2 p =Vector2.MoveTowards(transform.position,dest,speed); 
     GetComponent<Rigidbody2D>().MovePosition (p); 

     //check input for movement 
     if ((Vector2)transform.position == dest) 
     { 
      //up 
      if(Input.GetKey(KeyCode.W) && valid(Vector2.up) 
       dest = (Vector2)transform.position+Vector2.up; 

      if(Input.GetKey(KeyCode.S) && vaild(-Vector2.up) 
       dest = (Vector2)transform.position - Vector2.up; 

      if(Input.GetKey(KeyCode.D) && valid(Vector2.right) 
       dest = (Vector2)transform.position+Vector2.right; 

      if(Input.GetKey(KeyCode.A) && valid(-Vector2.right) 
       dest =(Vector2)transform.position-Vector2.right; 
     } 


     // Animation Parameters 
     Vector2 dir = dest - (Vector2)transform.position; 
     GetComponent<Animator>().SetFloat("DirX", dir.x); 
     GetComponent<Animator>().SetFloat("DirY", dir.y); 
    } 

    bool vaild (Vector2 dir) 
    { 
     //cast Line from 'Next to Septic Sam' to SepticSam 
     Vector2 pos= transform.position; 
     RaycastHit2D hit = Physics2D.Linecast (pos + dir, pos); 
     return (hit.collider == GetComponent<Collider2D>()); 
    } 
}

你缺少一個右括號：

if(Input.GetKey(KeyCode.W) && valid(Vector2.up) 
    dest = (Vector2)transform.position+Vector2.up; 

應該

if(Input.GetKey(KeyCode.W) && valid(Vector2.up)) //added ')' 
    dest = (Vector2)transform.position+Vector2.up;
