Equip Slot

An extension of Slot Base designed for items, in addition this slot has Equip Type property.


In order to change the equip slot tooltip you have to locate and change the method PrepareTooltip(UIItemInfo itemInfo) inside the Item Slot cs file.


The slot has three events, onAssign, onAssignWithSource and onUnassign.

Here is an example of eligible methods for the events.

public void OnAssign(UISpellSlot slot) { }

public void OnAssignWithSource(UISpellSlot slot, Object source) { }

public void OnUnassign(UISpellSlot slot) { }

Code Usage

You can access any slot via the static methods GetSlots(), GetSlotWithType(UIEquipmentType type) and GetSlotsWithType(UIEquipmentType type).

Here is an example of how to get and assign a item slot by id and group.

public void TestAssignSlot(UIEquipmentType type)
    UIEquipSlot slot = UIEquipSlot.GetSlotWithType(type);
    if (slot == null || UIItemDatabase.Instance == null)


You can implement unequip when thrown away by unchecking the property Allow Throw Away and overriding the method OnThrowAwayDenied().

/// <summary>
/// This method is raised when the slot is denied to be thrown away and returned to it's source.
/// </summary>
protected override void OnThrowAwayDenied()
    if (!this.IsAssigned())

    // Find free inventory slot
    List<UIItemSlot> itemSlots = UIItemSlot.GetSlotsInGroup(UIItemSlot_Group.Inventory);

    if (itemSlots.Count > 0)
        // Get the first free one
        foreach (UIItemSlot slot in itemSlots)
            if (!slot.IsAssigned())
                // Assign this equip slot to the item slot

                // Unassing this equip slot
