Camera collision detection.
Hi everybody, i'm in trouble with my Camera script. Camera rotates around player by using a pivot. assigned as a child of the camera. This works with 2 arrows (i'm developing this game for mobiles, so they're touch arrows) that allows camera to rotate left and right; the problem is when the camera goes behind a wall or a huge object and can't see nothing. I watched for some solution and I see that many developers used the RaycastHit or something similar. here's my code, the goal is that camera goes close to the pivot when hit a wall. Can anyone help me?
public Transform target1;
public Transform pivot;
protected ButtonLeft buttonLeft;
protected ButtonRight buttonRight;
public Vector3 offset;
public bool useOffsetValues;
public float rotateSpeed;
private void Start()
{
buttonLeft = FindObjectOfType<ButtonLeft>();
buttonRight = FindObjectOfType<ButtonRight>();
if (!useOffsetValues)
{
offset = target1.position - transform.position;
}
pivot.transform.position = target1.transform.position;
//pivot.transform.parent = target.transform;
//USE IF U WANT TO DISAPPEAR THE CURSOR
//Cursor.lockState = CursorLockMode.Locked;
//pivot.transform.parent = target.transform;
pivot.transform.parent = null;
// usa questa dopo la costruzione del livello1
//pivot.transform.position = target.transform.position;
}
private void Update()
{
pivot.transform.position = target1.transform.position;
if (buttonLeft.Pressed)
{
pivot.Rotate(0, -90 * Time.deltaTime, 0);
Debug.Log("rotate left");
}
if (buttonRight.Pressed)
{
pivot.Rotate(0, 90 * Time.deltaTime, 0);
Debug.Log("rotate left");
}
Ray ray = new Ray(pivot.transform.position, pivot.transform.position - transform.position);
RaycastHit hit;
/*float horizontal = Input.GetAxis("Mouse X") * rotateSpeed;
float horizontal = Input.GetAxis("Mouse X") * rotateSpeed;
pivot.Rotate(0, horizontal, 0);
pivot.Rotate(0, horizontal, 0);
Use this to make the camera rotate on Mouse Y axes*/
/*float vertical = Input.GetAxis("Mouse Y") * rotateSpeed;
target.Rotate(vertical, 0, 0); */
//move camera based on the current rotation of the target and the original offset
float desiredYAngle = pivot.eulerAngles.y;
//Use this float to set the x angle of player
float desiredXAngle = pivot.eulerAngles.x;
//Use this rotation only if you want to rotate on Y
//Quaternion rotation = Quaternion.Euler(0, desiredYAngle, 0);
//Use this if u want to rotate up&down on x axes
Quaternion rotation = Quaternion.Euler(desiredXAngle, desiredYAngle, 0);
transform.position = target1.position - (rotation * offset);
//transform.position = target.position - offset;
transform.LookAt(target1);
}
