Sometimes you need to check the scene in the project.

There are two points in this, and the calculation of the dash and front of the character

Dash with Lineranderer

The character is right in front of

Go.transform.forward + go.transform.position

The coordinates of the characters plus the forward direction of the characters.

(When I first hardheaded thinking of the front of the Go.transform.forward is not the front of the character, but if not add their own coordinates, it is only a direction, that is, this coordinate is only relative to the origin of the direction, plus coordinates is the point you want)

using System.Collections;  using System.Collections.Generic;  using UnityEngine;  public class DrawLine : MonoBehaviour {      public LineRenderer line;      public GameObject go;      // Use this for initialization      void Start () {     }      void Update()      {          Vector3 targetPos = go.transform.forward + go.transform.position;          line.SetPosition(0, go.transform.position);          line.SetPosition(1, targetPos);      }  }  

If it's just debug, there's an easier way.

Debug.DrawRay()Debug.DrawLine()
