How to Raycast by Angle in Unity

RayByAngle.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RayByAngle : MonoBehaviour {

	public float angle;
	public float distance = 1f;
	
	// Update is called once per frame
	void Update () {
		ShootRay();
	}

	void ShootRay()
	{
		var direction = Quaternion.AngleAxis(angle, transform.right) * transform.forward;
		
		Ray ray = new Ray(transform.position,direction);
		
		Debug.DrawLine(ray.origin,ray.origin + ray.direction * distance,Color.red);

		if(Physics.Raycast(ray,distance))
		{
			Debug.Log("Something is there");
		}
	
	}
}

Thanks for this, I needed to do this to get my characters to not be able to walk up slopes greater than this angle and it worked perfectly. It also solved the problem of my characters sometimes getting stuck on the edges of what the old code this replaced was hitting.

@Valignus I'm Glad it helped! <3
