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

Unity Engine
1

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…

using UnityEngine;
using System.Collections;

[ExecuteInEditMode]
public class DisplayTextureBetweenTwoScreenPositions : MonoBehaviour
{
    public Texture2D texture;
    [Range(0.0f, 1.0f)]
    public float xSize = 0.5f;
    [Range(0.0f, 1.0f)]
    public float ySize = 0.5f;
    public bool maintainAspectRatio = false;
    public bool pixelPerfect = false;
    public Vector2 normalizedScreenPosA = Vector2.zero;
    public Vector2 normalizedScreenPosB = Vector2.one;
    public bool rotate = true;

    private Vector3 screenPos;
    private Rect rect;
    private float angle;

    private Vector2 GetSize()
    {
        int sizeX = Mathf.RoundToInt(xSize * (float)Screen.width);
        int sizeY = maintainAspectRatio ? Mathf.RoundToInt((float)texture.height / (float)texture.width * (float)sizeX) : Mathf.RoundToInt(ySize * (float)Screen.height);
        if (pixelPerfect)
        {
            sizeX = texture.width;
            sizeY = texture.height;
        }

        return new Vector2(sizeX, sizeY);
    }

    void Update()
    {
#if UNITY_EDITOR
        if (texture != null)
        {
#endif
            Vector2 screenPosA = new Vector2(normalizedScreenPosA.x * Screen.width, normalizedScreenPosA.y * Screen.height);
            Vector2 screenPosB = new Vector2(normalizedScreenPosB.x * Screen.width, normalizedScreenPosB.y * Screen.height);
            Vector2 size = GetSize();

            if (rotate)
            {
                Vector2 tmp = screenPosA - screenPosB;
                angle = Mathf.Atan2(tmp.y, tmp.x) * Mathf.Rad2Deg;
            }

            Vector3 tmpScreenPos = Vector3.zero;
            tmpScreenPos.x = (screenPosA.x + screenPosB.x) * 0.5f;
            tmpScreenPos.y = (screenPosA.y + screenPosB.y) * 0.5f;
            screenPos = tmpScreenPos;

            Rect tmpRect = rect;
            tmpRect.center = new Vector2(screenPos.x, Screen.height - screenPos.y);
            tmpRect.width = size.x;
            tmpRect.height = size.y;
            rect = tmpRect;

#if UNITY_EDITOR
        }
#endif
    }

    void OnGUI()
    {
#if UNITY_EDITOR
        if (texture != null)
        {
#endif
            if (rotate)
            {
                Matrix4x4 tmp = GUI.matrix;
                GUIUtility.RotateAroundPivot(angle, rect.center);
                GUI.DrawTexture(rect, texture);
                GUI.matrix = tmp;
            }
            else
            {
                GUI.DrawTexture(rect, texture);
            }
#if UNITY_EDITOR
        }
#endif
    }
}
