smooth mouse look script

Okay I'm making an FPS shooter type game. awhile ago I found these two mouse look scripts earlier I need help fixing (and this is the first time I've really tried to script in C# opposed to java).One other thing I'd like to do although I am willing to use the the script twice on a child object is to make the script rotate the parent object's x axis while the child objects (put in a variable) y axis but I am willing to do otherwise : this script works more like I want it to and I can easily modify one of the variables to block off x rotation but I cannot set my own clamp to the y axis using UnityEngine; using System.Collections; // Very simple smooth mouselook modifier for the MainCamera in Unity by FatiguedArtist //(Francis R. Griffiths-Keam) - www.fatiguedartist.com [AddComponentMenu("Camera/Simple Smooth Mouse Look ")] public class SimpleSmoothMouseLook : MonoBehaviour { public bool lockCursor = false; public float sensitivity = 30; public int smoothing = 10; float ymove; float xmove; int iteration = 0; float xaggregate = 0; float yaggregate = 0; //int Ylimit = 0; public int Xlimit = 20; void Start() { // make the cursor invisible and locked? if (lockCursor) { Screen.lockCursor = true; } } void FixedUpdate () { // ensure mouseclicks do not effect the screenlock if (lockCursor) if (Input.GetMouseButtonDown(0) || Input.GetMouseButtonDown(1)) { Screen.lockCursor = true; } float[] x = new float[smoothing]; float[] y = new float[smoothing]; // reset the aggregate move values xaggregate = 0; yaggregate = 0; // receive the mouse inputs ymove = Input.GetAxis("Mouse Y"); xmove = Input.GetAxis("Mouse X"); // cycle through the float arrays and lop off the oldest value, replacing with the latest y[iteration % smoothing] = ymove; x[iteration % smoothing] = xmove; iteration++; // determine the aggregates and implement sensitivity foreach (float xmov in x) { xaggregate += xmov; } xaggregate = xaggregate / smoothing * sensitivity; foreach (float ymov in y) { yaggregate += ymov; } yaggregate = yaggregate / smoothing * sensitivity; // turn the x start orientation to non-zero for clamp Vector3 newOrientation = transform.eulerAngles + new Vector3(-yaggregate, xaggregate, 0); // xclamp = Mathf.Clamp(newOrientation.x, Xlimit, 360-Xlimit)%360; // rotate the object based on axis input (note the negative y axis) transform.eulerAngles = newOrientation; } } this script clamping rotation works fine but I can't click any buttons on the mouse or the script won't work any more, and while this script works smoothly it drags a little and does not stop when I no longer move the mouse. using UnityEngine; using System.Collections; using System.Collections.Generic; public class SmoothMouseLook : MonoBehaviour { /* This script is used to average the mouse input over x amount of frames in order to create a smooth mouselook. */ //Mouse look sensitivity public float sensitivityX = 2f; public float sensitivityY = 2f; //Default mouse sensitivity public float defaultSensX = 2f; public float defaultSensY = 2f; //Minimum angle you can look up public float minimumY = -60f; public float maximumY = 60f; //Number of frames to be averaged, used for smoothing mouselook public int frameCounterX = 35; public int frameCounterY = 35; //Mouse rotation input private float rotationX = 0f; private float rotationY = 0f; //Used to calculate the rotation of this object private Quaternion xQuaternion; private Quaternion yQuaternion; private Quaternion originalRotation; //Array of rotations to be averaged private List rotArrayX = new List (); private List rotArrayY = new List (); void Start () { //Lock/Hide cursor Screen.lockCursor = true; if (rigidbody) rigidbody.freezeRotation = true; originalRotation = transform.localRotation; } void Update () { if (Screen.lockCursor) { //Mouse/Camera Movement Smoothing: //Average rotationX for smooth mouselook float rotAverageX = 0f; rotationX += Input.GetAxis ("Mouse X") * sensitivityX; //Add the current rotation to the array, at the last position rotArrayX.Add (rotationX); //Reached max number of steps? Remove the oldest rotation from the array if (rotArrayX.Count >= frameCounterX) { rotArrayX.RemoveAt (0); } //Add all of these rotations together for (int i_counterX = 0; i_counterX = frameCounterY) { rotArrayY.RemoveAt (0); } for (int i_counterY = 0; i_counterY 360f) angle -= 360f; return Mathf.Clamp (angle, min, max); } }
