Making a shotgun in C#

Unity Engine
1

So, I’m having a bit of trouble with my shotgun, I don’t know how to offset it nor make multiple rays for the spread. Would anybody mind taking a look at it?

This is just the raycasting portion:

	void ShotgunFire () {
		
		RaycastHit hit;
		float range = Mathf.Infinity;
		bool firing = Physics.Raycast(transform.position, transform.forward, out hit, range);
		GameObject thing = hit.collider.gameObject;
		
	gunObj.transform.Translate(Vector3.forward * recoil);
	audio.PlayOneShot(gunshot);
		
	if(firing){
		if(thing.tag == "Untagged"){
			Instantiate(debrisParticle, hit.point, Quaternion.LookRotation(hit.normal));
			}
			
		if(thing.tag == "Player"){
			Instantiate(bloodParticle, hit.point, Quaternion.LookRotation(hit.normal));
			}
		}
	}

This will give you a shot with a random spread radius. I haven’t compile the code so there might be an error.

                var shotCount = 10;
		var spreadRadius = 0.5f;
		
		var gunForward = transform.forward;
		var gunPos = transform.position;
		var cachedTrans = transform;
		
		for(int i = 0; i < shotCount; i++)
		{
//Grab random vector
			var bulletVec = gunForward + 
				cachedTrans.TransformDirection(
				new Vector3(
					Random.Range(-spreadRadius, spreadRadius),
					Random.Range(-spreadRadius, spreadRadius),
					0));
			
			RaycastHit hit;
			float range = Mathf.Infinity;
		
			bool wasHit = Physics.Raycast(gunPos, bulletVec, out hit, range);

// check this ray
			if(!wasHit)
			{
				continue;
			}

			GameObject thing = hit.collider.gameObject;
			
			
			gunObj.transform.Translate(Vector3.forward * recoil);

			audio.PlayOneShot(gunshot);

			if(firing)
			{

				if(thing.tag == "Untagged")
				{
					Instantiate(debrisParticle, hit.point, Quaternion.LookRotation(hit.normal));
				}

				if(thing.tag == "Player")
				{
					Instantiate(bloodParticle, hit.point, Quaternion.LookRotation(hit.normal));
				}
			}
		}
