unity3d抛物线的脚本

把这个脚本挂在一个cube上，然后把另一个cube拖到target上，把这两个物体之间有一段距离，然后运行，就看到效果了

using UnityEngine;

using System.Collections;

public class ProjectileTest : MonoBehaviour

{

    public GameObject target;

    public float speed = 10;

    private float distanceToTarget;

    private bool move = true;

    void Start ()

    {

        distanceToTarget = Vector3.Distance (this.transform.position, target.transform.position);

        StartCoroutine (Shoot ());

    }

    

    IEnumerator Shoot ()

    {

        

        while (move) {

            Vector3 targetPos = target.transform.position;

            this.transform.LookAt (targetPos);

            float angle = Mathf.Min (1, Vector3.Distance (this.transform.position, targetPos) / distanceToTarget) * 45;

            this.transform.rotation = this.transform.rotation * Quaternion.Euler (Mathf.Clamp (-angle, -42, 42), 0, 0);

            float currentDist = Vector3.Distance (this.transform.position, target.transform.position);

            print ("currentDist" + currentDist);

            if (currentDist < 0.5f)

                move = false;

            this.transform.Translate (Vector3.forward * Mathf.Min (speed * Time.deltaTime, currentDist));

            yield return null;

        }

    }
