Closest game object script not working C#.

This is so annoying, i have no idea why its not finding closest object and setting it as "closest". Can someone please tell me whats wrong with this.

Code (CSharp):

1. for(int i = 0; i < weaponsOnGround.Count;i++){
2.                 distance = Mathf.Abs(transform.position.x + transform.position.z) - Mathf.Abs(weaponsOnGround[i].transform.position.x - weaponsOnGround[i].transform.position.z);
3.                 Checking = weaponsOnGround[i];
4.                 if(closest == null)closest = Checking;
5.                 if (distance < Mathf.Abs(closest.transform.position.x + closest.transform.position.z)) closest = Checking;
6.             }

 

Hi,
Calcul distance with the function Vector.Distance(). This should be work

Code (CSharp):

1. Vector2.Distance(vec1, vec2)

 

I'm using vector3's and i cant compare vectors with < or >.

 

I'm not certain but I think you can use the following to get the distance.

Code (CSharp):

1. float distance = (Vector1 - Vector2).magnitude;

 

Vector2.Distance returns a float

 

This?
