centering onGUI rects (solved)

below is some code for drawing my inventory, ive drawn all the rects in a grid based off of the amount of invslots, they originate from the top left corner and i'm wanting them to be in the center of the screen, i've tried modifying a few values but cant work it out, if you need a screenshot of the layout in playmode let me know, thanks for reading.

Code (CSharp):

1.  void DrawInventory()
2.     {
3.         Event e = Event.current;
4.         int i = 0;
5.         for (int y = 0 ; y < slotsY; y++)
6.         {
7.             for (int x = 0 ; x < slotsX; x++)
8.             {
9.                 Rect slotRect = new Rect  (x * 60, y * 60, 50, 50);
10.                 GUI.Box(new Rect(slotRect), "", skin.GetStyle("Slot"));
11.                 slots[i] = inventory[i];
12.                 if (slots[i].itemName != null)
13.                 {
14.                     GUI.DrawTexture(slotRect, slots[i].itemIcon);
15.                    if (slotRect.Contains(Event.current.mousePosition))
16.                     {
17.                        tooltip = CreatTooltip(slots[i]);
18.                         showTooltip = true;

 

i've tried setting the x and y max/min for the boxes based on the inventory slot but it produces a very strange result, they all cascade diagonally within each other,

Code (CSharp):

1.   Rect slotRect = new Rect  (x * 60, y * 60, 50, 50)  ;
2.                 slotRect.xMax = i + 100;
3.                 slotRect.xMin = i + 50;
4.                 slotRect.yMax = i + 100;
5.                 slotRect.yMin = i + 50;

 

forgive me for i am noob and should not code late at night or when hungover
Rect slotRect = new Rect (Screen.width/3 + x * 60, Screen.height /4 + y * 60, 50, 50) ;

 

Nice. Why don't you use canvas with automatic scaling and other stuff?

 

i was using the outdated GUI stuff, using unity UI now with canvas scaler etc, much easier
