Camera follows target rotation
I have a camera script that follows the player and i need the camera's rotation to be relative of the targets rotation. Example: The camera will view the player at a top down angle that is constantly turning with the player. Right now what its doing is the camera is following the player, but when i turn the player using the arrows the camera is not turning with the player.
using UnityEngine;
using System.Collections;
public class CameraFollow : MonoBehaviour {
public Transform target;
public float smoothTime = 0.1f;
public float speed = 3.0f;
public float followDistance = 10f;
public float verticalBuffer = 1.5f;
public float horizontalBuffer = 0f;
private Vector3 velocity = Vector3.zero;
public Quaternion rotation = Quaternion.identity;
void Update () {
Vector3 targetPosition = target.TransformPoint(new Vector3(horizontalBuffer, followDistance, verticalBuffer));
transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
rotation.eulerAngles = new Vector3(90, target.localRotation.y, target.localRotation.z);
rotation.y = target.rotation.y;
}
}
In order for the camera to turn with the player, the camera will need to rotate around the player. Take a look at the standard $$anonymous$$ouseOrbit script to get some ideas on how this is done.
using UnityEngine;
using System.Collections;
public class TransformToPlayer : MonoBehaviour {
public Transform target;
public float speed;
void Update() {
transform.eulerAngles = new Vector3(0, target.transform.eulerAngles.y, 0);
}
}
I figured it out thank you.
using UnityEngine;
using System.Collections;
public class CameraFollow : MonoBehaviour {
public Transform target;
public float smoothTime = 0.1f;
public float speed = 3.0f;
public float followDistance = 10f;
public float verticalBuffer = 1.5f;
public float horizontalBuffer = 0f;
private Vector3 velocity = Vector3.zero;
public Quaternion rotation = Quaternion.identity;
public float yRotation = 0.0f;
void Update () {
Vector3 targetPosition = target.TransformPoint(new Vector3(horizontalBuffer, followDistance, verticalBuffer));
transform.position = Vector3.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime);
//this is the code that solves the problem
transform.eulerAngles = new Vector3(90, target.transform.eulerAngles.y, 0);
//------------------------------------------------------------------------
}
}
I don't have time to test it out but you can try this:
YourCamera.transform.rotation = PlayerObject.transform.rotation;
Put that in the update loop and see if it works--I think it should work as you envision as long as the player is ONLY rotating on the x/y axis--one issue with this might be that it copies the initial z rotation of the player object--but it shouldn't change after that. it's worked for me in 2d projects--I'm not sure how well for 3d.
You could also try this:
float newRotation = PlayerObject.transform.eulerAngles.y;
float oldRotation = CameraObject.transform.eluerAngles.y;
YourCamera.transform.Rotate(0, newRotation - oldRotation, 0);
You should only need to rotate the camera on one axis--it should be your y or x axis. Try using the y axis first and then the x. I would also initialize the floats outside the update loop and define them in the loop--but this is a quick dirty test.
