Move object with

Hi everyone

I have my ball that will get throwed to an exact point, the starting piint is


Y = 2
Z = 0

Target position is

Y= 0
Z = 10

The point is, ihow do it, im totally confused

Any help?

 

In a straight line or with an arc? Straight line is easy:

Code (csharp):

1.  
2. public Vector3 start = new Vector3(0.0f, 2.0f, 0.0f);
3. public Vector3 end = new Vector3(0.0f, 0.0f, 10.0f);
4. public float lerp = 0.0f;
5.  
6. private void Update()
7. {
8.     transform.position = Vector3.Lerp(start, end, lerp);
9. }
10.  

Just adjust the lerp value between 0 and 1 while running.

 

Its an arc

 

Ok, still doable:

Code (csharp):

1.  
2. public Vector3 start = new Vector3(0.0f, 2.0f, 0.0f);
3. public Vector3 end = new Vector3(0.0f, 0.0f, 10.0f);
4. public float arc = 10.0f; // Height of the arc in the middle point
5. public float lerp = 0.0f;
6.  
7. private void Update()
8. {
9.     Vector3 position = Vector3.Lerp(start, end, lerp);
10.     float arcing = arc * 4.0f * (lerp - lerp * lerp);
11.     position.y += arcing;
12.     transform.position = position;
13. }
14.  

 

i'm trying to use your code, but it's not working

 

Compile error (which error) or does it do something other (what) than expected?

 

i'm using this script now, that's works fine

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. public class ParabolaScript : MonoBehaviour
4. {
5.     public Vector3 Target = new Vector3(10.0f,0,0);
6.     public float firingAngle = 45.0f;
7.     public float gravity = 9.8f;
8.     public Transform Projectile;    
9.     private Transform myTransform;
10.  
11.     void Awake()
12.     {
13.         myTransform = transform;    
14.     }
15.     void Start()
16.     {        
17.         StartCoroutine(SimulateProjectile());
18.     }
19.     IEnumerator SimulateProjectile()
20.     {
21.      
22.        /* // Move projectile to the position of throwing object + add some offset if needed.
23.         transform.position = myTransform.position + new Vector3(0, 0.0f, 0);*/
24.      
25.         // Calculate distance to target
26.         float target_Distance = Vector3.Distance(transform.position, Target);
27.         // Calculate the velocity needed to throw the object to the target at specified angle.
28.         float projectile_Velocity = target_Distance / (Mathf.Sin(2 * firingAngle * Mathf.Deg2Rad) / gravity);
29.         // Extract the X  Y componenent of the velocity
30.         float Vx = Mathf.Sqrt(projectile_Velocity) * Mathf.Cos(firingAngle * Mathf.Deg2Rad);
31.         float Vy = Mathf.Sqrt(projectile_Velocity) * Mathf.Sin(firingAngle * Mathf.Deg2Rad);
32.         // Calculate flight time.
33.         float flightDuration = target_Distance / Vx;
34.  
35.         // Rotate projectile to face the target.
36.         transform.rotation = Quaternion.LookRotation(Target - transform.position);
37.      
38.         float elapse_time = 0;
39.         while (elapse_time < flightDuration)
40.         {
41.             transform.Translate(0, (Vy - (gravity * elapse_time)) * Time.deltaTime, Vx * Time.deltaTime);
42.          
43.             elapse_time += Time.deltaTime;
44.             yield return null;
45.         }
46.     }
47. }
