Hi guys,
I found this awesome script for a target camera, but I want to add an iTween animation to it, where if a user presses a keyboard key, the camera moves to a new target position and zooms in at the same time. I figured out how to get it to move, but I can’t get it to zoom in while its moving…
Here is the script
using UnityEngine;
public class camera : MonoBehaviour
{
public Transform target;
public Vector3 targetOffset;
public Transform moveTarget;
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;
float distanceBetween;
private float desiredDistance;
private Quaternion currentRotation;
private Quaternion desiredRotation;
private Quaternion rotation;
private Vector3 position;
void Start() { Init(); }
void OnEnable() { Init(); }
public void Init()
{
//If there is no target, create a temporary target at 'distance' from the cameras current viewpoint
if (!target)
{
GameObject go = new GameObject("Cam Target");
go.transform.position = transform.position + (transform.forward * distance);
}
distance = Vector3.Distance(transform.position, target.position);
currentDistance = distance;
desiredDistance = distance;
//be sure to grab the current rotations as starting points.
position = transform.position;
rotation = transform.rotation;
currentRotation = transform.rotation;
desiredRotation = transform.rotation;
xDeg = Vector3.Angle(Vector3.right, transform.right);
yDeg = Vector3.Angle(Vector3.up, transform.up);
}
/*
* Camera logic on LateUpdate to only update after all character movement logic has been handled.
*/
void LateUpdate()
{
//Camera Orbit
if (Input.GetMouseButton(0))
{
xDeg += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
yDeg -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
//Clamp the vertical axis for the orbit
yDeg = ClampAngle(yDeg, yMinLimit, yMaxLimit);
desiredRotation = Quaternion.Euler(yDeg, xDeg, 0);
currentRotation = transform.rotation;
rotation = Quaternion.Lerp(currentRotation, desiredRotation, 2f);
transform.rotation = rotation;
}
//NEED SOLUTION HERE!
// Press B to move camera target AND zoom in on the target - how ?
if (Input.GetKeyUp(KeyCode.B)) {
iTween.MoveTo(target.gameObject,moveTarget.position,0.8f);
}
// 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);
// For smoothing of the zoom, lerp distance
currentDistance = Mathf.Lerp(currentDistance, desiredDistance, Time.deltaTime * zoomDampening);
// calculate position based on the new currentDistance
position = target.position - (rotation * Vector3.forward * currentDistance + targetOffset);
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);
}
}
Will appreciate all the help I can get, thanks.
