Unity让物体以弧线的形式运动到规定的坐标

1 u3d场景的设置

2， Run 脚本

using UnityEngine;
using System.Collections;

public class Run : MonoBehaviour
{
	public GameObject target;   //要到达的目标
	public float speed = 10;    //速度
	private float distanceToTarget;   //两者之间的距离
	private bool move = true;    

	void Start()
	{
		//计算两者之间的距离
		distanceToTarget = Vector3.Distance(this.transform.position, target.transform.position);  
		StartCoroutine(StartShoot());
	}

	IEnumerator StartShoot()
	{

		while (move)
		{
			Vector3 targetPos = target.transform.position;

			//让始终它朝着目标
			this.transform.LookAt(targetPos);

			//计算弧线中的夹角
			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);
			if (currentDist < 0.5f)
				move = true;
			this.transform.Translate(Vector3.forward * Mathf.Min(speed * Time.deltaTime, currentDist));
			yield return null;
		}
	}


}

3， 运行结果

重合到一起后，拖动Start的小球，松手后又会重合。

Good Luck.
