Setting an image to be drawn between two world positions through scripts

Wondering if anyone can help me out here, I'm wanting to draw an image between two positions on the screen. I know I can change the scale of the image in the X axis to scale it between the two but I'm requiring that it's accurate as well!

Many thanks!

 

I made something similar a while ago...

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. [ExecuteInEditMode]
5. public class DisplayTextureBetweenTwoScreenPositions : MonoBehaviour
6. {
7.     public Texture2D texture;
8.     [Range(0.0f, 1.0f)]
9.     public float xSize = 0.5f;
10.     [Range(0.0f, 1.0f)]
11.     public float ySize = 0.5f;
12.     public bool maintainAspectRatio = false;
13.     public bool pixelPerfect = false;
14.     public Vector2 normalizedScreenPosA = Vector2.zero;
15.     public Vector2 normalizedScreenPosB = Vector2.one;
16.     public bool rotate = true;
17.  
18.     private Vector3 screenPos;
19.     private Rect rect;
20.     private float angle;
21.  
22.     private Vector2 GetSize()
23.     {
24.         int sizeX = Mathf.RoundToInt(xSize * (float)Screen.width);
25.         int sizeY = maintainAspectRatio ? Mathf.RoundToInt((float)texture.height / (float)texture.width * (float)sizeX) : Mathf.RoundToInt(ySize * (float)Screen.height);
26.         if (pixelPerfect)
27.         {
28.             sizeX = texture.width;
29.             sizeY = texture.height;
30.         }
31.  
32.         return new Vector2(sizeX, sizeY);
33.     }
34.  
35.     void Update()
36.     {
37. #if UNITY_EDITOR
38.         if (texture != null)
39.         {
40. #endif
41.             Vector2 screenPosA = new Vector2(normalizedScreenPosA.x * Screen.width, normalizedScreenPosA.y * Screen.height);
42.             Vector2 screenPosB = new Vector2(normalizedScreenPosB.x * Screen.width, normalizedScreenPosB.y * Screen.height);
43.             Vector2 size = GetSize();
44.  
45.             if (rotate)
46.             {
47.                 Vector2 tmp = screenPosA - screenPosB;
48.                 angle = Mathf.Atan2(tmp.y, tmp.x) * Mathf.Rad2Deg;
49.             }
50.  
51.             Vector3 tmpScreenPos = Vector3.zero;
52.             tmpScreenPos.x = (screenPosA.x + screenPosB.x) * 0.5f;
53.             tmpScreenPos.y = (screenPosA.y + screenPosB.y) * 0.5f;
54.             screenPos = tmpScreenPos;
55.  
56.             Rect tmpRect = rect;
57.             tmpRect.center = new Vector2(screenPos.x, Screen.height - screenPos.y);
58.             tmpRect.width = size.x;
59.             tmpRect.height = size.y;
60.             rect = tmpRect;
61.  
62. #if UNITY_EDITOR
63.         }
64. #endif
65.     }
66.  
67.     void OnGUI()
68.     {
69. #if UNITY_EDITOR
70.         if (texture != null)
71.         {
72. #endif
73.             if (rotate)
74.             {
75.                 Matrix4x4 tmp = GUI.matrix;
76.                 GUIUtility.RotateAroundPivot(angle, rect.center);
77.                 GUI.DrawTexture(rect, texture);
78.                 GUI.matrix = tmp;
79.             }
80.             else
81.             {
82.                 GUI.DrawTexture(rect, texture);
83.             }
84. #if UNITY_EDITOR
85.         }
86. #endif
87.     }
88. }
