我想在2D游戏中为我的角色创建一个动作脚本，但是我无法获得正确的raycast。我只是想能够移动我想要的任何方向，直到我进入距物体一定距离内。然后我想让它停止移动，我做错了什么？我的光线广播全部返回0.Raycast Unity运动脚本
using UnityEngine;
using System.Collections;
public class Character : MonoBehaviour
{
[SerializeField]
private float speed;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void Update()
{
RaycastHit2D hitUp = Physics2D.Raycast(transform.position, -Vector2.up);
RaycastHit2D hitDown = Physics2D.Raycast(transform.position, -Vector2.down);
RaycastHit2D hitLeft = Physics2D.Raycast(this.gameObject.transform.position, -Vector2.left, 10.0f);
RaycastHit2D hitRight = Physics2D.Raycast(transform.position, -Vector2.right);
if (Controller.player == 1)
{
if (Input.GetKey(KeyCode.A) && hitLeft.distance > 1)
{
transform.position += Vector3.left * speed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.D) && hitRight.distance > 1)

transform.position += Vector3.right * speed * Time.deltaTime;
