Hi,
i got the problem on this script zoom and rotate works fine but panning is not work i have try to solve this but not yet get. Help me to do this.
Here is the code:
//In a file MaxCamera.cs
using UnityEngine;
using System.Collections;
public class MaxCamera : MonoBehaviour{
public Transform target;
public Vector3 targetOffset;
public float distance = 5.0f;
public float maxDistance = 20;
public float minDistance = .6f;
public float xSpeed = 200.0f;
public float ySpeed = 200.0f;
public int yMinLimit = -80;
public int yMaxLimit = 80;
public int zoomRate = 40;
public float panSpeed = 0.3f;
public float zoomDampening = 5.0f;
private float xDeg = 0.0f;
private float yDeg = 0.0f;
private float currentDistance;
private float desiredDistance;
RaycastHit hit;
void Start()
{
Vector3 angles = transform.eulerAngles;
xDeg = angles.x;
yDeg = angles.y;
currentDistance = distance;
desiredDistance = distance;
}
void Update()
{
Ray ray = Camera.mainCamera.ScreenPointToRay(camera.transform.position);
if(Physics.Raycast(ray , out hit, 50.0f))
{
if(hit.collider)
print("Now its hiting some thing");
}
}
/**
* Camera logic on LateUpdate to only update after all character movement logic has been handled.
*/
void LateUpdate()
{
// Don't do anything if target is not defined
if (!target)
return;
// If Control and Alt and Middle button? ZOOM!
if (Input.GetMouseButton(2) Input.GetKey(KeyCode.LeftAlt) Input.GetKey(KeyCode.LeftControl))
{
desiredDistance -= Input.GetAxis("Mouse Y") * Time.deltaTime * zoomRate*0.125f * Mathf.Abs(desiredDistance);
}
// If middle mouse and left alt are selected? ORBIT
//else if (Input.GetMouseButton(2) Input.GetKey(KeyCode.LeftAlt))
else if (Input.GetMouseButton(1))
{
xDeg += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
yDeg -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
}
// otherwise if middle mouse is selected, we pan by way of transforming the target in screenspace
else if (Input.GetMouseButton(2))
{
//grab the rotation of the camera
// target.rotation = transform.rotation;
transform.Translate(transform.right * -Input.GetAxis("Mouse X") * panSpeed );
transform.Translate(Vector3.up * -Input.GetAxis("Mouse Y") * panSpeed);
}
// affect the desired Zoom distance if we roll the scrollwheel
desiredDistance -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * zoomRate * Mathf.Abs(desiredDistance);
//clamp the zoom min/max
desiredDistance = Mathf.Clamp(desiredDistance, minDistance, maxDistance);
//Clamp the vertical axis for the orbit
yDeg = ClampAngle(yDeg, yMinLimit, yMaxLimit);
// set camera rotation
Quaternion rotation = Quaternion.Euler(yDeg, xDeg, 0);
// For smoothing of the zoom, lerp distance
currentDistance = Mathf.Lerp(currentDistance, desiredDistance, Time.deltaTime * zoomDampening);
// keep within legal limits
currentDistance = Mathf.Clamp(currentDistance, minDistance, maxDistance);
// calculate position based on the new currentDistance
Vector3 position = target.position - (rotation * Vector3.forward * currentDistance + targetOffset );
print(rotation * Vector3.forward * currentDistance + targetOffset );
//Vector3 position = transform.position;
transform.rotation = rotation;
transform.position = position;
}
private static float ClampAngle(float angle, float min, float max)
{
if (angle < -360)
angle += 360;
if (angle > 360)
angle -= 360;
return Mathf.Clamp(angle, min, max);
}
