i am building a camera rotation script like in fps. Everything is setup and working except that camera rotation resets to zero at the start of game which i dont want.
This is the camera rotation i want:
![alt text][1]
This is rotation of character my script is attached to:
![alt text][2]
And after hitting play it resets camera rotation to (0,0,0). i want it to remain how i have set it in inspector. i am using quaternion.slerp to rotate camera around to rotations on the basis of touch inputs. After reset to (0,0,0) everything works fine.please help, i have always had a hard time understanding quaternion LOL!
this is the script:
public class ScreenCharacterController : MonoBehaviour
{
#region Fields
private Camera mainCamera;
private CharacterController character;
private int leftFingerID = -1;
private int rightFingerID = -1;
private Vector2 leftFingerInput;
private Vector2 rightFingerInput;
private float xAxisRotation;
private float yAxisRotation;
[SerializeField] private float minXRotation;
[SerializeField] private float maxXRotation;
[SerializeField] private float minYRotation = -25f;
[SerializeField] private float maxYRotation = 25f;
[SerializeField] private float cameraRotationSpeed = 20f;
