When a user clicks mouse0 I set a
Vector2 orgBoxPos = Input.mousePosition;
While he is holding down mouse0, I constantly update
Vector2 endBoxPos = Input.mousePosition;
I then try this to draw this box on the screen (ie: imagine an RTS style selection box):
GUI.DrawTexture(new Rect(orgBoxPos.x, Screen.height - orgBoxPos.y, endBoxPos.x - orgBoxPos.x, Screen.height - endBoxPos.y - orgBoxPos.y), selectTexture);
All of the Rect coords are correct except the last one (Remember unity GUI y coords are inverted, for some funky reason).
For some reason I can't seem to figure out how to correctly calculate the end height of my rectangle.
Any help would be greatly appreciated!
