FPS camera with y-axis limit to certain angle
Solution 1:
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);
}
