掛載在物體上,需要給地形添加Terrain標簽

using UnityEngine; using System.Collections; public class dfdfdfdf : MonoBehaviour
{ //目標點坐標 private Vector3 mTargetPos; public float speed=5f; void Start()
    {

    } void Update()
    { //按下鼠標右鍵時 if (Input.GetMouseButton(1))
        { //獲取屏幕坐標 Vector3 mScreenPos = Input.mousePosition; //定義射線 Ray mRay = Camera.main.ScreenPointToRay(mScreenPos);
            RaycastHit mHit; //判斷射線是否擊中地面 if (Physics.Raycast(mRay, out mHit))
            { if (mHit.collider.gameObject.tag == "Terrain")
                { //獲取目標坐標 mTargetPos = mHit.point; //讓主角面朝目標坐標并向目標移動 transform.LookAt(mTargetPos); //播放奔跑動畫 //transform.gameObject.GetComponent<Animation>().Play("run"); transform.Translate(Vector3.forward * speed*Time.deltaTime);
                }
            }
        } //松開鼠標右鍵時 //if (Input.GetMouseButtonUp(1)) //{ //    transform.gameObject.GetComponent<Animation>().Play("idle"); //} }
}

第二種方法,移動到鼠標點擊位置

掛載在物體上,需要給地面添加Plane標簽

using UnityEngine; using System.Collections; public class dfdfdfdf : MonoBehaviour
{
        Ray ray;
        RaycastHit hit; bool state = false; public float moveSpeed; // Use this for initialization void Start()
        {

        } // Update is called once per frame void Update()
        { if (Input.GetMouseButtonDown(0))
            {
                ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit))
                { if (hit.collider.tag == "Plane")
                    {
                        state = true;
                    }
                }
            } if (state)
            {
                transform.forward = Vector3.Lerp(transform.forward, hit.point - transform.forward, Time.deltaTime);
                transform.position = Vector3.MoveTowards(transform.position, hit.point, Time.deltaTime * moveSpeed);
            }
        }
}
