How to use RaycastHit ?
I want to get the distance between an object and a hit point and so I think I need to use RaycastHit. I tried this code but it doesn't output anything,
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class newSensor : MonoBehaviour {
float dist;
// Use this for initialization
void Start()
{
}
// Update is called once per frame
void FixedUpdate()
{
RaycastHit hit;
if (Physics.Raycast(transform.position, Vector3.forward, out hit, Mathf.Infinity))
{
Debug.Log(hit.distance);
}
}
}
Thank you for helping me :)
If it does not output anything, it means you don't have any collider in your scene or the ray does not hit them. Use Debug.DrawRay to visualise your ray.
https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html
Debug.DrawRay(transform.position, Vector3.forward * 500, Color.green);
