Clamping when Zoom changes?
I've got a basic camera I am working on for a 2D game that moves with the player and clamps to the area of the map. To this I've introduced a combination of player and eventual height-based zoom sort of Ski Safari or Lunar Lander style.
Zooming, however, changes the clamp positions and allows the land edges to be seen again. How can I fix this in the code, to prevent the edges that should be clamped from being seen when zoom is in effect?
using UnityEngine;
public class CameraController : MonoBehaviour
{
public int zoomSpeed = 1;
public int zoomMax = 25;
public int zoomMin = 50;
public float tarVelocity;
public GameObject target;
public Vector3 offset;
private Vector3 targetPos;
private Camera _cam;
void Start()
{
_cam = GetComponent<Camera>();
targetPos = transform.position;
}
void FixedUpdate()
{
if (target)
{
Vector3 targetDirection = (target.transform.position - transform.position);
tarVelocity = targetDirection.magnitude * 5f;
targetPos = transform.position + (targetDirection.normalized * tarVelocity * Time.deltaTime);
transform.position = Vector3.Lerp(transform.position, targetPos + offset, 0.25f);
}
}
void LateUpdate()
{
ClampCamera();
CheckZoom();
Vector3 posNoZ = transform.position;
posNoZ.z = -10;
transform.position = posNoZ;
}
private void ClampCamera()
{
Vector3 clampMovement = transform.position;
clampMovement.x = Mathf.Clamp(clampMovement.x, 8f, 112);
clampMovement.y = Mathf.Clamp(clampMovement.y, 6.6f, 100);
transform.position = clampMovement;
}
private void CheckZoom()
{
if (Input.GetAxis("Mouse ScrollWheel") > 0 && Camera.main.orthographicSize > zoomMax)
Camera.main.orthographicSize -= zoomSpeed;
if (Input.GetAxis("Mouse ScrollWheel") < 0 && Camera.main.orthographicSize < zoomMin)
Camera.main.orthographicSize += zoomSpeed;
}
}
