unity3d抛物线的脚本

using UnityEngine;
using System.Collections;


public class ProjectileTest : MonoBehaviour

    public GameObject target;
    public float speed = 10;

            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;

}

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
