Description

Modified version of Standard Assets MouseLook.cs, it moves the camera with an easing effect. I basically applied a solution found at Unity Community Scripting Forum to the original C# script.

<csharp>using UnityEngine; using System.Collections; using System.Collections.Generic;

[AddComponentMenu("Camera-Control/Smooth Mouse Look")] public class SmoothMouseLook : MonoBehaviour {

public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 } public RotationAxes axes = RotationAxes.MouseXAndY; public float sensitivityX = 15F; public float sensitivityY = 15F;

public float minimumX = -360F; public float maximumX = 360F;

public float minimumY = -60F; public float maximumY = 60F;

float rotationX = 0F; float rotationY = 0F;

private List<float> rotArrayX = new List<float>(); float rotAverageX = 0F;

private List<float> rotArrayY = new List<float>(); float rotAverageY = 0F;

public float frameCounter = 20;

Quaternion originalRotation;

void Update () { if (axes == RotationAxes.MouseXAndY) { rotAverageY = 0f; rotAverageX = 0f;

rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationX += Input.GetAxis("Mouse X") * sensitivityX;

rotArrayY.Add(rotationY); rotArrayX.Add(rotationX);

if (rotArrayY.Count >= frameCounter) { rotArrayY.RemoveAt(0); } if (rotArrayX.Count >= frameCounter) { rotArrayX.RemoveAt(0); }

for(int j = 0; j < rotArrayY.Count; j++) { rotAverageY += rotArrayY[j]; } for(int i = 0; i < rotArrayX.Count; i++) { rotAverageX += rotArrayX[i]; }

rotAverageY /= rotArrayY.Count; rotAverageX /= rotArrayX.Count;

rotAverageY = ClampAngle (rotAverageY, minimumY, maximumY); rotAverageX = ClampAngle (rotAverageX, minimumX, maximumX);

Quaternion yQuaternion = Quaternion.AngleAxis (rotAverageY, Vector3.left); Quaternion xQuaternion = Quaternion.AngleAxis (rotAverageX, Vector3.up);

transform.localRotation = originalRotation * xQuaternion * yQuaternion; } else if (axes == RotationAxes.MouseX) { rotAverageX = 0f;

rotationX += Input.GetAxis("Mouse X") * sensitivityX;

rotArrayX.Add(rotationX);

if (rotArrayX.Count >= frameCounter) { rotArrayX.RemoveAt(0); } for(int i = 0; i < rotArrayX.Count; i++) { rotAverageX += rotArrayX[i]; } rotAverageX /= rotArrayX.Count;

rotAverageX = ClampAngle (rotAverageX, minimumX, maximumX);

Quaternion xQuaternion = Quaternion.AngleAxis (rotAverageX, Vector3.up); transform.localRotation = originalRotation * xQuaternion; } else { rotAverageY = 0f;

rotationY += Input.GetAxis("Mouse Y") * sensitivityY;

rotArrayY.Add(rotationY);

if (rotArrayY.Count >= frameCounter) { rotArrayY.RemoveAt(0); } for(int j = 0; j < rotArrayY.Count; j++) { rotAverageY += rotArrayY[j]; } rotAverageY /= rotArrayY.Count;

rotAverageY = ClampAngle (rotAverageY, minimumY, maximumY);

Quaternion yQuaternion = Quaternion.AngleAxis (rotAverageY, Vector3.left); transform.localRotation = originalRotation * yQuaternion; } }

void Start () { if (rigidbody) rigidbody.freezeRotation = true; originalRotation = transform.localRotation; }

public static float ClampAngle (float angle, float min, float max) { angle = angle % 360; if ((angle >= -360F) && (angle <= 360F)) { if (angle < -360F) { angle += 360F; } if (angle > 360F) { angle -= 360F; } } return Mathf.Clamp (angle, min, max); } }</csharp>
