Uniyt3d物体跟随鼠标方向移动

第一个脚本实现效果：鼠标单机移动物体
基础部分终于看的差不多了。


要开始写代码，实现效果了~


程序基础不怎么好，慢慢来~~


点击鼠标左键 物体移动到鼠标位置


C#实现


using UnityEngine;
using System.Collections;


public class Script_01 : MonoBehaviour 
{

private Vector3 world;
private float speed;//the move speed of object

void Start () 
{

}



void Update () 
{
Vector3 screenpos=Camera.main.WorldToScreenPoint(transform.position);//turn the coordinate of object from World to Screen
Vector3 m=Input.mousePosition;//the position of mouse

//when mouse click
if(Input.GetMouseButton(0))
{
m.z=screenpos.z;//give a z axis coordinate to mouse
world=Camera.main.ScreenToWorldPoint(m);//change to world coordinate 
speed=30;
}
if(transform.position==world)
{
speed=0;
}
transform.LookAt(world);//let the object look at mouse
transform.Translate(Vector3.forward*speed*Time.deltaTime);
}
}
