unity3d 抛物线（炮弹轨迹）【代码】

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

1. using UnityEngine;
   
2. using System.Collections;
   
3. 
   
4. 
   
5. public class ProjectileTest : MonoBehaviour
   
6. {
   
7.     public GameObject target;
   
8.     public float speed = 10;
   
9.     private float distanceToTarget;
   
10.     private bool move = true;
    
11. 
    
12. 
    
13.     void Start ()
    
14.     {
    
15.         distanceToTarget = Vector3.Distance (this.transform.position, target.transform.position);
    
16.         StartCoroutine (Shoot ());
    
17.     }
    
18.    
    
19.     IEnumerator Shoot ()
    
20.     {
    
21.         
    
22.         while (move) {
    
23.             Vector3 targetPos = target.transform.position;
    
24.             this.transform.LookAt (targetPos);
    
25.             float angle = Mathf.Min (1, Vector3.Distance (this.transform.position, targetPos) / distanceToTarget) * 45;
    
26.             this.transform.rotation = this.transform.rotation * Quaternion.Euler (Mathf.Clamp (-angle, -42, 42), 0, 0);
    
27.             float currentDist = Vector3.Distance (this.transform.position, target.transform.position);
    
28.             print ("currentDist" + currentDist);
    
29.             if (currentDist < 0.5f)
    
30.                 move = false;
    
31.             this.transform.Translate (Vector3.forward * Mathf.Min (speed * Time.deltaTime, currentDist));
    
32.             yield return null;
    
33.         }
    
34.     }
    
35. }
