How to make the camera follow a GameObject
At first, save this as "SmoothFollow.cs" in the Assets folder.
using UnityEngine;
using System.Collections;
public class SmoothFollow : MonoBehaviour {
// The target we are following
public Transform target;
// The distance in the x-z plane to the target
//So this would be your offset
public float distance = 10.0f;
// the height we want the camera to be above the target
public float height = 5.0f;
// How much we
public float heightDamping = 2.0f;
public float rotationDamping = 3.0f;
// Place the script in the Camera-Control group in the component menu
[AddComponentMenu("Camera-Control/Smooth Follow")]
void LateUpdate () {
// Early out if we don't have a target
if (!target) return;
// Calculate the current rotation angles
float wantedRotationAngle = target.eulerAngles.y;
float wantedHeight = target.position.y + height;
float currentRotationAngle = transform.eulerAngles.y;
float currentHeight = transform.position.y;
// Damp the rotation around the y-axis
currentRotationAngle = Mathf.LerpAngle(currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
// Damp the height
currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
// Convert the angle into a rotation
var currentRotation = Quaternion.Euler(0, currentRotationAngle, 0);
// Set the position of the camera on the x-z plane to:
// distance meters behind the target
transform.position = target.position;
transform.position -= currentRotation * Vector3.forward * distance;
// Set the height of the camera
transform.position = new Vector3(transform.position.x,currentHeight,transform.position.z);
// Always look at the target
transform.LookAt(target);
}
}
Then you can add this script to the main camera.
Create an object to be followed
I made an object to be followed.
Then add the SmoothFollow.cs script to the main camera object.
Then add the object to be followed as target.
Now start the project. The camera follows the object.
