I am starting a new game and right now my player can view 360* but I want to limit how far the player looks up in the sky and down (straight up and down). Here's my code
Vector2 mouseLook;
Vector2 smoothV;
public float sensitivity = 5.0f;
public float smoothing = 2.0f;
GameObject player;
void Start () {
player = this.transform.parent.gameObject;
}
// Update is called once per frame
void Update () {
var md = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
md = Vector2.Scale(md, new Vector2(sensitivity * smoothing, sensitivity * smoothing));
smoothV.x = Mathf.Lerp(smoothV.x, md.x, 1f / smoothing);
smoothV.y = Mathf.Lerp(smoothV.y, md.y, 1f / smoothing);
mouseLook += smoothV;
transform.localRotation = Quaternion.AngleAxis(-mouseLook.y, Vector3.right);
player.transform.localRotation = Quaternion.AngleAxis(mouseLook.x, player.transform.up);
}
}

You have to use Mathf.Clamp
to do this. Below is what I use to rotate the camera up/down and left/right. You can modify the yMaxLimit
and yMinLimit
variables to the angles you want to limit it to. There should be no limit while moving in the x
direction.
public float xMoveThreshold = 1000.0f;
public float yMoveThreshold = 1000.0f;
public float yMaxLimit = 45.0f;
public float yMinLimit = -45.0f;
float yRotCounter = 0.0f;
float xRotCounter = 0.0f;
Transform player;
void Start()
{
player = Camera.main.transform;
}
// Update is called once per frame
void Update()
{
xRotCounter += Input.GetAxis("Mouse X") * xMoveThreshold * Time.deltaTime;
yRotCounter += Input.GetAxis("Mouse Y") * yMoveThreshold * Time.deltaTime;
yRotCounter = Mathf.Clamp(yRotCounter, yMinLimit, yMaxLimit);
//xRotCounter = xRotCounter % 360;//Optional
player.localEulerAngles = new Vector3(-yRotCounter, xRotCounter, 0);
}
