1、抛物场景具体如下图，可参见下面百度经验搭建
2、选中Antitank蘅荫酸圉Grende 脚本，双击脚本或者右键 Open C# Project 打开脚本进行编辑，具体如下图
3、AntitankGrende 的具体代码如下图
4、AntitankGrende 脚本具体内容如下：using UnityEngine;public class AntitankGrende : MonoBehaviour { public Transform player; public Transform antitank; LineRenderer line; public int count; float g; float mVelocity; private void Awake() { line = GetComponent<LineRenderer>(); g = Mathf.Abs(Physics.gravity.y); } // Use this for initialization void Start () { } // Update is called once per frame void Update () { } public void CallRendererLine(float _velocity){ mVelocity = _velocity; line.positionCount = (count + 1); line.SetPositions(CalculatePostion()); } Vector3[] CalculatePostion() { Vector3[] _array = new Vector3[count + 1]; float _radianAngle; _radianAngle = Mathf.Deg2Rad * -player.localEulerAngles.x; for (int i = 0; i <= count; i++) { float _t = (float)i / count; _array[i] = CalulatePoint(_t, _radianAngle); } return _array; } Vector3 CalulatePoint(float _t, float _radianAngle) { float _y = mVelocity * Mathf.Sin(_radianAngle) * _t - 1 / 2f * g * _t * _t; float _x = mVelocity * Mathf.Cos(_radianAngle) * _t * Mathf.Sin(player.localEulerAngles.y * Mathf.Deg2Rad); float _z = mVelocity * Mathf.Cos(_radianAngle) * _t * Mathf.Cos(player.localEulerAngles.y * Mathf.Deg2Rad); return (new Vector3(_x, _y, _z) + antitank.position); }}j小本编译正确回到Unity界面，把脚本挂载到 LineRenderer 上，对象进项参数赋值，具体如下图
5、选中Test脚本，双击脚本或者右键 Open C# Project 打开脚本进行编辑，具体如下图
6、Test 脚本的代码如下图
7、Test 脚本的具体内容如下：using System.Collectio艘绒庳焰ns;using UnityEngine;publi艘早祓胂c class Test : MonoBehaviour { public AntitankGrende line; public Transform player; public float ExplosiveTime; public Rigidbody rig; public float velocity; // Use this for initialization void Start () { } // Update is called once per frame void Update () { if (Input.GetMouseButton(0)) line.CallRendererLine(velocity); if (Input.GetMouseButtonUp(0)) AntitankGrenadeOut(); } void AntitankGrenadeOut() { line.gameObject.SetActive(false); float _n = velocity / Time.fixedDeltaTime; float _angleY = Mathf.Deg2Rad * -player.localEulerAngles.x; float _angleX = Mathf.Deg2Rad * player.localEulerAngles.y; Vector3 _force = new Vector3(_n * Mathf.Cos(_angleY) * Mathf.Sin(_angleX), _n * Mathf.Sin(_angleY), _n * Mathf.Cos(_angleY) * Mathf.Cos(_angleX)); rig.AddForce(_force); rig.useGravity = true; this.transform.SetParent(null); StartCoroutine(Explosive()); } IEnumerator Explosive() { yield return new WaitForSeconds(ExplosiveTime); transform.GetChild(0).gameObject.SetActive(true); yield return new WaitForSeconds(0.7f); transform.gameObject.SetActive(false); }}
8、脚本编译正确，回到Unity界面，把脚本挂载到 Sphere上面，对应参数赋值，具体如下图
9、运行场景，点击鼠标左键，生成抛物线，抬起鼠标左键，物体飞出，具体如下图
10、到此，《Unity 抛物体教程二之 抛物体功能抛物运动实现》讲解结束，谢谢
