Make Random.InitState relative to a position ?

Hello, actually for the position i use vector.sqrmagnitude bot the problem with is if i have a gameObject in position ( 5,0,0 ) and another in position ( 0,5,0) they will have the same value.

Code (CSharp):

1.   void setSystemValue()
2.     {
3.         RaycastHit hit;
4.         Ray ray = cam.ScreenPointToRay(Input.mousePosition);
5.  
6.  
7.  
8.         if (Physics.Raycast(ray, out hit, Mathf.Infinity))
9.         {
10.  
11.  
12.             Random.InitState((int)hit.transform.position.sqrMagnitude);
13.  

 

So use the xyz values in a clever way to get a new number, maybe use each axis as a seed, take the 3 numbers and add/multiply/divide/subtract them at will to get a new seed.

Theres probably a better way, but you get idea i hope.
