Hi guys!
So I have this script I want to use as a way to draw sprites in the editor to later turn these sprites into gameobjects. But now I'm trying to get the drag-and-dropping of sprites to work. That is, untill this morning when my script started to crash the Editor. I have tried to open the window in a new project, but it gave me the same results.
Code:
public class SpritePaintingTools : EditorWindow
{
#region Window
[MenuItem("Painting Tools/Sprite Painter", false, 2)]
public static void Init()
{
SpritePaintingTools window = (SpritePaintingTools)GetWindow(typeof(SpritePaintingTools));
window.Show();
window.minSize = new Vector2(200, 250);
}
#endregion
//An int to referance the button that is curantly pressed.
int toolInt;
//The text to fill the toolbar.
string[] toolNames = new string[] { "Paint", "Erase", "Edit Layout" };
//An rect to set the toolbar to.
static Rect toolbar;
//An rect to set the grid to.
static Rect gridBackground;
//Mouse offset
public static Vector2 mouseOffset = new Vector2(1000, 1000);
//Mouse zoom
static float zoom;
//The sprites in the curent editor.
public static List sprites = new List();
private void OnGUI()
{
#region Setting some settings
#region Setting the Rects
toolbar = new Rect(25, 25, position.width - 50, (position.width - 50) / 10);
gridBackground = new Rect(25, 50 + toolbar.height, position.width - 50, position.height - toolbar.height - 75);
#endregion
#region Setting the mouse offset
if (Event.current != null && Event.current.type == EventType.MouseDrag && Event.current.button == 1)
{
mouseOffset += Event.current.delta;
Repaint();
}
#endregion
#region Setting the mouse zoom
float _zoom = zoom;
if (Event.current.isScrollWheel)
{
_zoom += Event.current.delta.y;
}

If you guys know what I'm doing wrong I would very much like to know. I have been working on this for AGES...
