Camera Rotation Locked up

Questions & Answers
1

Hello,

I’m trying to create a script to allow a camera to follow a ball and rotate around it using J and L (for now). I’m currently having issues getting the camera to look at the ball while rotating, I’m using transform.LookAt(player.transform.position); but my other line transform.position = player.transform.position + offset; is overriding it and not allowing it to rotate.

as of yet I have no idea how to go about fixing this issue.

Thank you for taking the time to look at my question!

Here’s The entire Script just in case;

public class CameraController : MonoBehaviour 
{
	public GameObject player;
	private Vector3 offset;
	public int rotateSpeed;

	// Use this for initialization
	void Start () 
	{
		offset = transform.position;
	}
	
	// Update is called once per frame
	void LateUpdate ()
	{
		transform.LookAt(player.transform.position);
		transform.position = player.transform.position + offset;

		//Controls
		if(Input.GetKey(KeyCode.J))
		{
			transform.RotateAround(player.transform.position - offset, Vector3.down, Time.deltaTime * rotateSpeed);
		}
		else if(Input.GetKey(KeyCode.L))
		{
			transform.RotateAround(player.transform.position - offset, Vector3.up, Time.deltaTime * rotateSpeed);
		}

	}
}

There are several ways to approach this problem. Working within the framework of your existing code, there are a few changes that make it behave how you describe:

public class CameraController : MonoBehaviour 
{
	public Transform player;
	private Vector3 offset;
	public int rotateSpeed;
	
	void Start () 
	{
		offset = transform.position - player.position;
	}
	
	void LateUpdate ()
	{

		if(Input.GetKey(KeyCode.J))
		{
			transform.RotateAround(player.transform.position, Vector3.down, Time.deltaTime * rotateSpeed);
			offset = transform.position - player.position;
		}
		else if(Input.GetKey(KeyCode.L))
		{
			transform.RotateAround(player.transform.position, Vector3.up, Time.deltaTime * rotateSpeed);
			offset = transform.position - player.position;
		}

		transform.position = player.transform.position + offset;
		transform.LookAt(player.transform.position);
	}
}

I tried plugging in your code but the camera just ended up in a static position staring at the ball from a distance. No idea why. A buddy of mine suggested this code but the offset aspect of it doesn’t work as well as one would hope.

public class CameraController : MonoBehaviour 
{
	public Transform player;
	private Vector3 offset;
	public float rotateSpeed;

	public bool isRotate = false;
	
	void Start () 
	{
		offset = transform.position;
	}


	void LateUpdate ()
	{
		transform.position = player.transform.position + offset;
		transform.LookAt(player.transform.position);
	
	
		if(isRotate)
		{
			//Controls
			if(Input.GetKey(KeyCode.J))
			{
				offset = Quaternion.AngleAxis(player.transform.position.x  * rotateSpeed, Vector3.down) * offset;
			}
			else if(Input.GetKey(KeyCode.L))
			{
				offset = Quaternion.AngleAxis(player.transform.position.x * rotateSpeed, Vector3.up) * offset;
			}
		}
	
	}
}
