Hi! I want to draw some sprites to use as icons in a menu screen, when I draw the menu with only a single item it's working fine, but when the menu has more than one item, it crashes with the following:

- (engine.Object.R_DrawSpritePatch)
- R_DrawSpritePatch
- VObject::ExecuteFunction
- (uibase.MenuSpriteAnim.OnDraw)
- VWidget::DrawTree
- VWidget::DrawTree
- VWidget::DrawTree
- VRootWidget::DrawWidgets
- SCR_Update
- Host_Frame

Here's the code I'm using to draw:

void CreateWeaponEntries(int YPos)
{
	int i;
	MenuTaggedTextButton Btn, Btn2;
	MenuSpriteAnim		Anim;
	Inventory Item = cl.WeaponFirst;

	i = 0;
	while (Item)
	{
		if (HexenWeapon(Item).Slot == SlotCurrent)
		{
			// [FB] Make sure to add any weapon icons to be used here
			R_InstallSprite(va("%n", HexenWeapon(Item).IconName), i);

			Anim = MenuSpriteAnim(NewChild(MenuSpriteAnim));
			Anim.SetPos(ChoicesStartX + 6, YPos + 4);
			Anim.SprDef = i;
			Anim.Speed = 1;
			Anim.NumFrames = 1;
			
			Btn = MenuTaggedTextButton(NewChild(MenuTaggedTextButton));
			Btn.Tag = i++;
			Btn.SetOrigin(ChoicesStartX + 46, YPos + 2);
			if (StrStartsWith(Item.PickupMessage, "$"))
			{
				Btn.Text = GetLangString(StrToName(substr(Item.PickupMessage, 1, strlen(Item.PickupMessage) - 1)));
			}
			else
			{
				Btn.Text = Item.PickupMessage;
			}
			Btn.Width = 600;

			if (cl.WeaponsBelt[SlotCurrent] == Item)
			{
				SelectedEntry = Btn;
				Btn.TextColour = CR_YELLOW;
				Btn.TextColourFocus = CR_GOLD;
			}
			else
			{
				Btn.TextColour = CR_UNTRANSLATED;
				Btn.TextColourFocus = CR_WHITE;
			}
			Btn.Activated = WeaponSelect;
			YPos += Btn.Height;
			// [FB] Let's not forget to increase the sprite index here
			i++;
		}

		Item = Item.NextWpn();
	}
}

My guess is that the problem is with the sprites index, maybe I'm not understanding how they work, could you please explain me how this works or if the problem is in the code? Thanks!
