Raycast Impact Effect Shotgun Help

Hey guys, I'm working on making a shotgun for my FPS.

I've pretty much built it on top of my script I was using to fire an auto rifle.

I got the shotgun to work fine with spread and all, but I can't get the shots to register unless I hit the target with my center shot. Like the spread only appears once i hit them with what feels like a main raycast.

It I shoot at the floor for example only one shot registers.

I'll drop my script below, if anyone could help I'd really appreciate it. Thanks again for any insight.

Code (CSharp):

1.  void secShoot()
2.     {
3.  
4.         for (int i = 0; i < shotFragments; i++)
5.         {
6.             currentMag--;
7.  
8.             SetMagBarUi();
9.  
10.             Vector3 shootDirection = MainCamera.transform.forward;
11.  
12.             Vector3 weaponObjectLocalPosition = WeaponObject.transform.localPosition;
13.  
14.             weaponObjectLocalPosition.z = weaponObjectLocalPosition.z - secRecoilAmount;
15.  
16.             WeaponObject.transform.localPosition = weaponObjectLocalPosition;
17.  
18.             shootDirection.x += Random.Range(-spreadFactor, spreadFactor);
19.  
20.             shootDirection.y += Random.Range(-spreadFactor, spreadFactor);
21.  
22.             muzzleFlash.Play();
23.  
24.             nextFire = Time.time + secFireRate;
25.  
26.             Quaternion fireRotation = Quaternion.LookRotation(transform.forward);
27.  
28.             Quaternion randomRotation = Random.rotation;
29.  
30.             fireRotation = Quaternion.RotateTowards(fireRotation,randomRotation,Random.Range(0.0f,spreadAngle));
31.  
32.             if (Physics.Raycast(MainCamera.transform.position, fireRotation*Vector3.forward, out hit, Mathf.Infinity))
33.             {
34.                 Instantiate(secImpactEffect, hit.point, Quaternion.LookRotation(hit.normal));
35.  
36.                 GameObject go = Instantiate<GameObject>(secImpactEffect, hit.point, Quaternion.LookRotation(hit.normal));
37.  
38.                 IDamageable damageable = hit.collider.GetComponent<IDamageable>();
39.  
40.                 hit.rigidbody.AddForceAtPosition(transform.forward * secHitForce, hit.point);
41.  
42.                 float normalisedDistance = hit.distance / secMaximumRange;
43.  
44.                 if (damageable != null)
45.                 {
46.                     if (normalisedDistance <= 1)
47.                     {
48.                         damageable.DealDamage(Mathf.RoundToInt(Mathf.Lerp(secMaximumDamage, secMinimumDamage, normalisedDistance)));
49.                     }
50.                 }
51.             }
52.         }
53.     }

 

Use shotDirection for raycast direction instead of Vector3.forward.

 

Thanks, I'll take a look and make that change as soon as I get home from work.

Also, just to clarify this change is done on line 40, correct?

 

Hey, I meant line 32. And that did't work. I tried shootDirection and still nothing. By any chance does anything else look wrong about it?

 

As I think I've told you before, slap some Debug.Logs all across that bad boy to see what's going on, put one after every if statement, loop iteration, function call.

 

This

Code (CSharp):

1. Debug.DrawLine(MainCamera.transform.position, MainCamera.transform.position + fireRotation, Color.red, 3);

will draw red lines for every raycast for 3 seconds in the Scene view so you may clearly see what's going on.

 

Thanks palex, I'll get right on it tonight.

 

Lmao I always forget to use that tool for things like this. Thanks again man.

 

Hey bro, good afternoon.

I'm getting issues with the "+" being used there.

I'll leave an image below of the error.

What could be used to replace that "+" symbol?

 

You cant add a quaternion to a vector3, you can multiply them, but quaternion comes first,
fireRotation * camera.position
