unity c# fps camera movement script code example
Example 1: fps camera unity
public float turnSpeed = 4.0f;
public float moveSpeed = 2.0f;
public float minTurnAngle = -90.0f;
public float maxTurnAngle = 90.0f;
private float rotX;
void Update ()
{

KeyboardMovement();
}
void MouseAiming ()
{
float y = Input.GetAxis("Mouse X") * turnSpeed;
rotX += Input.GetAxis("Mouse Y") * turnSpeed;
rotX = Mathf.Clamp(rotX, minTurnAngle, maxTurnAngle);
transform.eulerAngles = new Vector3(-rotX, transform.eulerAngles.y + y, 0);
}
void KeyboardMovement ()
{
Vector3 dir = new Vector3(0, 0, 0);
dir.x = Input.GetAxis("Horizontal");
dir.z = Input.GetAxis("Vertical");
transform.Translate(dir * moveSpeed * Time.deltaTime);
}
