Raycasting issues

As well the raycast(debug.drawline) is going the opposite way to the mouse pointer location.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System;
4.  
5. public class Weapon : MonoBehaviour {
6.  
7.     public float fireRate = 0;
8.     public float Damage = 10;
9.     public LayerMask whatToHit;
10.     public GameObject playerObject;
11.     private bool m_FacingRight = true;
12.     public Transform BulletTrailPrefab;
13.     public Transform MuzzleFlashprefab;
14.     float timetoSpawnEffect = 0;
15.     public float effectSpawnRate = 10;
16.     private float move;
17.  
18.     float timeToFire = 0;
19.     public Transform firePoint;
20.  
21.     // Use this for initialization
22.     void Awake() {
23.         Transform firePoint = transform.FindChild("firePoint");
24.         if (firePoint == null) {
25.             Debug.LogError("No FirePoint? what?!?");
26.  
27.             {
28.             }
29.  
30.         }
31.     }
32.  
33.     // Update is called once per frame
34.     void Update() {
35.         if (fireRate == 0) {
36.             if (Input.GetButtonDown("Fire1")) {
37.                 Shoot();
38.             }
39.         }
40.         else {
41.             if (Input.GetButton("Fire1") && Time.time > timeToFire) {
42.                 timeToFire = Time.time + 1 / fireRate;
43.                 Shoot();
44.                 if (move < 0)
45.                 {
46.                     m_FacingRight = false;
47.                     transform.localRotation = Quaternion.Euler(0, 180, 0);
48.                 }
49.                 else
50.                 {
51.                     m_FacingRight = true;
52.                     transform.localRotation = Quaternion.Euler(0, 0, 0);
53. }
54.             }
55.         }
56.     }
57.     private void Shoot()
58.     {
59.         Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
60.         Vector2 shootDirection = (mousePosition - (Vector2)firePoint.position).normalized;
61.         Ray2D ray = new Ray2D(mousePosition, shootDirection);
62.  
63.         RaycastHit2D hit = Physics2D.Raycast(ray.origin, ray.direction, 100, whatToHit);
64.  
65.         if (hit.collider != null)
66.         {
67.             Debug.DrawLine(ray.origin, hit.point, Color.green);
68.             Debug.Log("We hit " + hit.collider.name + " and did " + Damage + " damage.");
69.         }
70.         else
71.         {
72.             Debug.DrawRay(ray.origin, ray.direction * 100, Color.red);
73.         }
74.  
75.         if (Time.time >= timetoSpawnEffect)
76.         {
77.             Effect();
78.             timetoSpawnEffect = Time.time + 1 / effectSpawnRate;
79.         }
80.     }
81.     private void Effect() {
82.         Instantiate(BulletTrailPrefab, firePoint.position, firePoint.rotation);
83.         Transform Clone = Instantiate (MuzzleFlashprefab, firePoint.position, firePoint.rotation) as Transform;
84.         Clone.parent = firePoint;
85.         float size = UnityEngine.Random.Range(0.7f, 0.9f);
86.         Clone.localScale = new Vector3 (size, size, size);
87.         Destroy (Clone.gameObject, 0.2f);
88.     }
89. }
90.  

 

Have you tried inverting the direction?

Code (csharp):

1. Vector2 shootDirection = (mousePosition + (Vector2)firePoint.position).normalized;

Change the '-' to a '+'. What is the result?

 

I have a little class that will help you with selected objects

Code (CSharp):

1.  
2. using System;
3. using UnityEngine;
4.  
5. public class Utilities2D
6. {
7. /// <summary>
8. ///  This will return a 2D gameobject ONLY using orthographic projection
9. ///  use the 3D version if your object is a 3D object but is in a 2D world.
10. /// </summary>
11. /// <returns>selected gameobject otherwise null</returns>
12. public static GameObject SelectObject()
13. {
14.   GameObject mObject = null;
15.   Ray mRay = Camera.main.ScreenPointToRay(Input.mousePosition);
16.   RaycastHit2D mHit = Physics2D.Raycast(mRay.origin, Vector2.zero, Mathf.Infinity);
17.   if (mHit != null && mHit.collider != null)
18.    mObject = mHit.collider.gameObject;
19.  
20.   return mObject;
21. }
22. }
23.
