本文探讨了如何使用Unity引擎实现机器人控制与交互功能，通过鼠标点击选择目标，利用射线投射与物理引擎判断碰撞，进而控制机器人进行移动与转向。文章详细介绍了代码实现过程，包括输入捕捉、碰撞检测、移动控制和动画切换等关键步骤。

//以下是实现代码

using UnityEngine;
using System.Collections;

public class SampleMoveScriptC : MonoBehaviour {

public float speed = 3.0f;
public float rotatationSpeed = 200.0f;
private float curSpeed = 0.0f;

private GameObject obj = null;
private Vector3 point;

// Use this for initialization
void Start () {
  obj = GameObject.Find("robot");
}

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

  if(Input.GetMouseButtonDown(0))//Down或Up
     {
         Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         RaycastHit hit;
         if(Physics.Raycast(ray,out hit))
         {
          if(hit.collider.gameObject.name=="Cube")//射线碰撞到的物体名称
          {
          point = hit.point;
     obj.transform.LookAt(new Vector3(point.x, obj.transform.position.y, point.z));

          }
   }
     }

  float newSpeed = Input.GetAxis("Vertical") * speed;
  if (Input.GetKey("left shift"))
  {
   newSpeed *= 1.5f;
  }
  float distance = Vector3.Distance(point, transform.position);
  CharacterController controller = obj.GetComponent<CharacterController>();
  Vector3 forward = Vector3.ClampMagnitude(point - obj.transform.position, 1.5f);
  if(Mathf.Abs(distance) > 1.45f && controller)
  {

   obj.animation.CrossFade("run");
   controller.SimpleMove(forward * 1.5f);
  }
  else
  {
   obj.animation.CrossFade("idle");
  }

}
