Camera Follow Target(Smooth Follow)

Unity Engine
1

Can someone make me a very simple camera follow target script? Or at least link me to where i can make my own. I tried using smooth follow but i dont like the rotation of it and dont know how to change it.

Noob.

dont have time to make a exemple right now, but the docs do inlcuded a basic version of what you want.

I found some

I appreciate your humor but none of those youtube videos helped. They all used smoothfollow. And some were for 2d games.

Noob.

I will try what you gave and report back.

Yea sure Google entry NR4 Unity3D: Third-Person Cameras | Envato Tuts+
Not for 2D and not using the unity smoothfollow script. 5 Seconds of search…
Good luk with your try

Alright thanks. I will report back.

            myTransform.LookAt(target);
        }
    }
   
    //this runs every frame, directly after Update
    void LateUpdate()
    {//use this so that changes are immediate after the object has been affected
   
        Vector3 targetPos = GetTargetPos();
        //calculate drift theta
        float t = Vector3.Distance(myTransform.position, targetPos) / maxDriftRange;
       
        //smooth camera position using drift theta
        myTransform.position = Vector3.Lerp(myTransform.position, targetPos, t * Time.deltaTime);
        //look at our target
        myTransform.LookAt(target);
    }
   
    void OnDrawGizmos()
    {//this is for editor purpose only, shows the relationship between this script and target as a line
        Gizmos.color = Color.yellow;
        Gizmos.DrawLine(myTransform.position, target.position);
    }
   
    private Vector3 GetTargetPos()
    {//returns where the camera should aim to be
        //opposite of (-forward) * distance
        Vector3 targetPos = new Vector3(0, 0, -distance);
        //calculate pitch and yaw
        targetPos = Quaternion.Euler(angleX, angleY, 0) * targetPos;
        //return angled target position relative to target.position
        return target.position + (target.rotation * targetPos);
    }
}

This script is smoother than some things I can think of! lol >.>
