Raycast hit.point issue

Hey I am creating a ballistics system, however I have an issue with the Raycast Hit.
The hit.point is always landing in the incorrect position. Here is an image.

There is a sphere showing the trajectory of the bullet floating in the air. there is also a sphere being instantiated on the ground and the hit.point as you can see the sphere on the ground is not where the line hits the ground.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class projectile2 : MonoBehaviour {
6.  
7.     public float velocity;
8.  
9.     Vector3 Next_Position;
10.     GameObject Hit_Object;
11.     Vector3 Hit_Normal;
12.     Transform trns;
13.     float dwnVel;
14.     public float mass;
15.     float g = 9.81f;
16.     public GameObject marker;
17.     public float velocityLoss;
18.     public GameObject Explosion_Object;
19.     void FixedUpdate(){
20.         // saves the next position
21.         Vector3 Vec3 = trns.position + trns.forward * velocity * Time.fixedDeltaTime + Vector3.down * dwnVel * Time.fixedDeltaTime;
22.  
23.         // Spawns the marker from the bullet generator along the trajectory
24.         GameObject trajmark = (GameObject) Instantiate (marker, trns.position, trns.rotation);
25.         drawline linemarker = trajmark.gameObject.GetComponent<drawline>();
26.         linemarker.setup (trns.position + trns.forward * velocity * Time.fixedDeltaTime + Vector3.down * dwnVel * Time.fixedDeltaTime);
27.         // //
28.  
29.         // raycasts to test for collision
30.         RaycastHit hit;
31.         if (Physics.Raycast (trns.position, Vec3, out hit)) {
32.             Debug.Log("HIT" + hit.point);
33.             //trns.position = Vec3;
34.             Instantiate ( marker , hit.point , Quaternion.identity ) ;
35.             Destroy (this.gameObject);
36.         } else {
37.             trns.position = Vec3;
38.         }
39.         // //
40.  
41.         // increase the downward velocity
42.         dwnVel += (mass * g);
43.         if (velocity > 0.0f) {
44.             velocity += velocityLoss * Time.fixedDeltaTime;
45.         } else {
46.             velocity = 0.0f;
47.         }
48.         // //
49.     }
50.  
51.     // Use this for initialization
52.     void Start () {
53.         trns = this.transform;
54.  
55.     }
56. }
57.  
58.  

 

Added comments to help make it more readable, the issue is in the raycast but it uses the same Vec3 variable so I have no idea why this issue is occuring?

 

Still really need some assistance with this have got none so far and I've been wrestling with it for more than a day now

 

You use the end point "Vec3" as a direction vector for you Raycast, you should use the difference with the current position to get the actual direction:

Code (csharp):

1.  
2. if (Physics.Raycast(trns.position, Vec3 - trns.position, out hit))
3.  

Does it helps ?

 

That solved the issue thanks so much
