How to limit/Clamp RotateAround for camera movement?
I have a scene with a globe, where the camera is rotating around the globe. I need to clamp the position and rotation of this movement in certain instances of the game. I have tried several methods but none have worked. My code is below:
private void LateUpdate()
{
if (Input.GetMouseButtonDown(1))
mouseStartPosition = GetMouseHit();
if (mouseStartPosition != null)
DragPlanet();
if (Input.GetMouseButtonUp(1))
StaticPlanet();
}
public void RotateCamera(Vector3 dragStartPosition, Vector3 dragEndPosition)
{
//normalised for odd edges
dragEndPosition = dragEndPosition.normalized *planetRadius;
dragStartPosition = dragStartPosition.normalized * planetRadius;
// Cross Product
Vector3 cross = Vector3.Cross(dragEndPosition, dragStartPosition);
// Angle for rotation
float angle = Vector3.SignedAngle(dragEndPosition, dragStartPosition, cross);
//Causes Rotation of angle around the vector from Cross product
holderTransform.RotateAround(planet.transform.position, cross, angle);
}
private static Vector3? GetMouseHit()
{
RaycastHit hit;
int layer_mask = LayerMask.GetMask("Planet"); //raycasting on the planet
if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hit, Mathf.Infinity, layer_mask))
{
return hit.point;
}
