Hello
I’m working on a scene with a MainCamera. Attached to it I have a CameraRotatorScript:
using UnityEngine;
public class CameraRotator : MonoBehaviour
{
public Transform target;
public Camera mainCamera;
[Range(0.1f, 5f)] [Tooltip("How sensitive the mouse drag to camera rotation")]
public float mouseRotateSpeed = 0.8f;
[Range(0.01f, 100)] [Tooltip("How sensitive the touch drag to camera rotation")]
public float touchRotateSpeed = 17.5f;
[Tooltip("Smaller positive value means smoother rotation, 1 means no smooth apply")]
public float slerpValue = 0.25f;
public enum RotateMethod
{
Mouse,
Touch
}
[Tooltip("How do you like to rotate the camera")]
public RotateMethod rotateMethod = RotateMethod.Mouse;
private Vector2 swipeDirection; // swipe delta vector2
private Quaternion cameraRot; // store the quaternion after the slerp operation
private Touch touch;
private float distanceBetweenCameraAndTarget;
private readonly float minXRotAngle = -80; // min angle around x axis
private readonly float maxXRotAngle = 80; // max angle around x axis
//Mouse rotation related
private float rotX; // around x
private float rotY; // around y
private void Awake()
{
if (mainCamera == null)
{
mainCamera = Camera.main;
}
}
// Start is called before the first frame update
void Start()
{
distanceBetweenCameraAndTarget = Vector3.Distance(mainCamera.transform.position, target.position);
}
// Update is called once per frame
void Update()
{
switch (rotateMethod)
{
case RotateMethod.Mouse:
{
if (Input.GetMouseButton(0))
{
rotX += -Input.GetAxis("Mouse Y") * mouseRotateSpeed; // around X
rotY += Input.GetAxis("Mouse X") * mouseRotateSpeed;
}
if (rotX < minXRotAngle)
{
rotX = minXRotAngle;
}
else if (rotX > maxXRotAngle)
{
rotX = maxXRotAngle;
}
break;
}
case RotateMethod.Touch:
{
if (Input.touchCount > 0)
{
touch = Input.GetTouch(0);
switch (touch.phase)
{
case TouchPhase.Began:
//Debug.Log("Touch Began");
break;
case TouchPhase.Moved:
swipeDirection += touch.deltaPosition * Time.deltaTime * touchRotateSpeed;
break;
case TouchPhase.Ended:
//Debug.Log("Touch Ended");
break;
}
}
if (swipeDirection.y < minXRotAngle)
{
swipeDirection.y = minXRotAngle;
}
else if (swipeDirection.y > maxXRotAngle)
{
swipeDirection.y = maxXRotAngle;
}
break;
}
}
}
private void LateUpdate()
{
Vector3 dir = new Vector3(
0,
0,
-distanceBetweenCameraAndTarget); // assign value to the distance between the maincamera and the target
// value equal to the delta change of our mouse or touch position
Quaternion newQ = rotateMethod == RotateMethod.Mouse
? Quaternion.Euler(rotX, rotY, 0) // We are setting the rotation around X, Y, Z axis respectively
: Quaternion.Euler(swipeDirection.y, -swipeDirection.x, 0);
cameraRot = Quaternion.Slerp(
cameraRot,
newQ,
slerpValue); // let cameraRot value gradually reach newQ which corresponds to our touch
mainCamera.transform.position = target.position + (cameraRot * dir);
mainCamera.transform.LookAt(target.position);
}
public void SetCamPos()
{
if (mainCamera == null)
{
mainCamera = Camera.main;
}
mainCamera.transform.position = new Vector3(
0,
0,
-distanceBetweenCameraAndTarget);
}
}
This works in the editor so far. But as soon, building the WebGL output, the camera can not be rotated anymore.
Does some of you have an idea what I’m missing?
Kind regards
