Clamp RotateAround is not working on Camera.
My code is not working, I am trying to clamp the camera, but its not working. Its snapping to 45 instantly. How to clamp the camera?
Here is my Code.
using UnityEngine;
using System.Collections;
public class MoveCamera : MonoBehaviour
{
public float sensitivity = 4.0f;
private Vector3 mouseOrigin;
private bool isRotating;
private float minX = -45.0f;
private float maxX = 45.0f;
private float minY = -10.0f;
private float maxY = 10.0f;
float rotationY = 0.0f;
float rotationX = 0.0f;
void Start()
{
}
void Update ()
{
if (Input.GetMouseButtonDown (0)) {
mouseOrigin = Input.mousePosition;
isRotating = true;
}
if (!Input.GetMouseButton (0))
isRotating = false;
if (isRotating) {
Vector3 pos = Camera.main.ScreenToViewportPoint (Input.mousePosition - mouseOrigin);
transform.RotateAround (transform.position, transform.right, -pos.y * sensitivity);
transform.RotateAround (transform.position, Vector3.up, pos.x * sensitivity);
rotationY = Mathf.Clamp (transform.localEulerAngles.y, minY, maxY);
rotationX = Mathf.Clamp (transform.localEulerAngles.x, minX, maxX);
transform.localEulerAngles = new Vector3 (-rotationY, rotationX, 0);
}
}
}

OK, I fixed it, Here is complete code.
using UnityEngine;
using System.Collections;
public class MoveCamera : MonoBehaviour
{
public float sensitivity = 4.0f;
private Vector3 mouseOrigin;
private bool isRotating;
public GameObject cam;
void Start()
{
}
protected float ClampAngle(float angle, float min, float max) {
angle = NormalizeAngle(angle);
if (angle > 180) {
angle -= 360;
} else if (angle < -180) {
angle += 360;
}
min = NormalizeAngle(min);
if (min > 180) {
min -= 360;
} else if (min < -180) {
min += 360;
}
max = NormalizeAngle(max);
if (max > 180) {
max -= 360;
} else if (max < -180) {
max += 360;
}
return Mathf.Clamp(angle, min, max);
}
protected float NormalizeAngle(float angle) {
while (angle > 360)
angle -= 360;
while (angle < 0)
angle += 360;
return angle;
}
void Update ()
{
if (Input.GetMouseButtonDown (0)) {
mouseOrigin = Input.mousePosition;
isRotating = true;
}
if (!Input.GetMouseButton (0))
isRotating = false;
if (isRotating) {
cam.transform.localEulerAngles = new Vector3(0, ClampAngle(cam.transform.localEulerAngles.y, -45, 45), 0);
Vector3 pos = Camera.main.ScreenToViewportPoint (Input.mousePosition - mouseOrigin);
transform.RotateAround (transform.position, transform.right, -pos.y * sensitivity);
transform.RotateAround (transform.position, Vector3.up, pos.x * sensitivity);
}
}
}
