Selection box - drawing corner issue.
Hello! So im trying to select objects with my selection box. The drawing part runs perfecly,but selection is not happening, if selection box wasnt drawn from an upper right corner.
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using RTS;
public class testSelectionBox : MonoBehaviour {
public Texture2D texture;
bool draw;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update()
{
if (Input.GetMouseButtonDown(0))
{
draw = true;
rect = new Rect(Input.mousePosition.x, -(Input.mousePosition.y - Screen.height), 100, 100);
}
}
if (Input.GetMouseButtonUp(0))
{
for (int i = 0; i < ResourceManager.playerUnits.Count; i++)
{
if (rect.Contains(WorldToGuiPoint(ResourceManager.playerUnits[i].transform.position)))
{
Debug.Log(playerUnits[i].name);
}
}
draw = false;
}
if (Input.GetMouseButton(0) && draw)
{
rect.xMax = Input.mousePosition.x;
rect.yMax = Screen.height-Input.mousePosition.y;
}
Debug.Log(rect);
}
void OnGUI()
{
if (draw)
{
GUI.DrawTexture(rect, texture);
}
}
public Vector3 WorldToGuiPoint(Vector3 position)
{
Vector3 guiPosition = Camera.main.WorldToScreenPoint(position);
guiPosition.y = Screen.height - guiPosition.y;
return guiPosition;
}
}

Fixed by using
Rect selectionBox = new Rect(Mathf.Min(startingCursorPos.x, currentCursorPos.x), Mathf.Min(startingCursorPos.y, currentCursorPos.y),
Mathf.Abs(startingCursorPos.x - currentCursorPos.x),
Mathf.Abs(startingCursorPos.y - currentCursorPos.y));
