Hardware accelerated mouse

AngryBots does not have hardware accelerated mouse support. It's not supported in Unity 3 outside of plugins.

So while hardware acceleration for the mouse is not part of Unity3D (thanks Eric), there seems to be a good way of simulating this to the best effect possible (at least that's the best solution I found after hours of research). Credit should go to this post for giving me the idea: http://forum.unity3d.com/threads/118864-Matching-quot-Fake-quot-Cursor-to-system-mouse-speed-(Suggestion-for-Screen.clampCursor)

In my (short) experience Input.mousePosition is generally good, however, when you are moving the mouse in a fast manner, the software cursor will be noticeably lagging behind the actual hardware cursor. You can see this by setting Screen.showCursor to True.

However, since the effect only happens during rapid movements, one can simply extrapolate from the current movement velocity in order to display the cursor at the point where the user "feels" it is. So in order to perform such a "software acceleration" you can simple lock the mouse and use the mouse delta in order to derive the current mouseposition. By then multiplying the mouse delta with a feasible value (such as 1.5) you artificially created a very smooth mouse acceleration that will sufficiently enough simulate rapid movements that are in line with the user expectation.

Here the code in C#:

 using UnityEngine;
 using System.Collections;
 
 public class MouseCursor : MonoBehaviour {
     public GameObject cursor;
     private GameObject _cursor;
     
     // Use this for initialization
     void Start () {
         Screen.lockCursor = true;
         Screen.showCursor = false;
         _cursor = (GameObject) Instantiate(cursor);
         _cursor.transform.position = new Vector3(0.5f, 0.5f, 0f);
     }
     
     // Update is called once per frame
     void Update () {
         Vector3 mouseDelta = new Vector3( Input.GetAxis("Mouse X") , Input.GetAxis("Mouse Y"), 0f ) * 1.5f;
         Vector3 pos = Camera.main.ScreenToViewportPoint(mouseDelta) + _cursor.transform.position;
         
         _cursor.transform.position = pos;
         
     }
 }
