[CodeSource]Simple draw line from GUI

This is the code where we can change their color and size:

Code (CSharp):

1. public class temp : MonoBehaviour {
2.    
3.     public Vector2 A   = Vector2.zero;
4.     public Vector2 B   = Vector2.zero;
5.     public Color color = Color.black;
6.     public int size    = 1;
7.        
8.     void DrawLine(Vector2 pointA, Vector2 pointB,Color color,int size)
9.     {
10.         size = Mathf.Max(size,1);
11.         Texture2D point = new Texture2D(1,1);
12.         point.SetPixel(0,0,color);
13.         point.Apply();
14.         float distance = Vector2.Distance(pointA,pointB);
15.         Rect rect = new Rect();
16.         rect.size = new Vector2(size,size);
17.         for(int i=0;i<=Mathf.RoundToInt(distance);i++){
18.  
19.             rect.position = Vector2.Lerp(pointA,pointB,i/distance);
20.             GUI.DrawTexture(rect,point);
21.  
22.         }
23.  
24.     }
25.    
26.     void OnGUI(){
27.        
28.         DrawLine(A,B,color,size);
29.        
30.     }
31.    
32. }
