## Common Patterns

### Check If Player Is Home

```lua
local function CheckHousingState()
    if HousingUI.IsPlayerInOwnHouse() then
        print("Welcome home!")
        local houseInfo = HousingUI.GetCurrentHouseInfo()
        if houseInfo then
            print("House:", houseInfo.name)
        end
    elseif HousingUI.IsPlayerInHouse() then
        local owner = HousingUI.GetHouseOwner()
        if owner then
            print("Visiting", owner.name, "'s house")
        end
    end
end
```

### Place a Decoration

```lua
-- Enter housing edit mode and place an item
local function PlaceDecoration(catalogItemID)
    if not HousingUI.IsHousingModeActive() then
        HousingUI.EnterHousingMode()
    end
    
    local current, max = C_HouseEditorUI.GetPlacementLimits()
    if current >= max then
        print("Decoration limit reached:", current, "/", max)
        return
    end
    
    C_HouseEditorUI.PlaceObject(catalogItemID)
end
```

### Browse Catalog

```lua
local function BrowseCatalog()
    local categories = C_HousingCatalog.GetCategories()
    for _, cat in ipairs(categories) do
        local catInfo = C_HousingCatalog.GetCategoryInfo(cat)
        if catInfo then
            print("Category:", catInfo.name)
            local items = C_HousingCatalog.GetItemsInCategory(cat)
            for _, item in ipairs(items) do
                local info = C_HousingCatalog.GetItemInfo(item)
                if info then
                    local owned = C_HousingCatalog.IsItemOwned(item)
                    print("  -", info.name, owned and "(Owned)" or "")
                end
            end
        end
    end
end
```

### Save and Load Layouts

```lua
-- Save current decoration layout
HousingLayoutUI.SaveLayout("My Living Room v2")

-- List saved layouts
local layouts = HousingLayoutUI.GetSavedLayouts()
for _, layout in ipairs(layouts) do
    local info = HousingLayoutUI.GetLayoutInfo(layout)

        print(info.name, "-", info.objectCount, "objects")
    end
end
```

## Gotchas & Restrictions

1. **12.0.0 only** — The entire housing system is new in Patch 12.0.0. APIs may evolve in subsequent patches.
2. **Mode requirements** — Must call `HousingUI.EnterHousingMode()` before using editor functions.
3. **Placement limits** — Each house has a decoration cap. Check with `GetPlacementLimits()`.
4. **Expert vs Basic mode** — Expert mode allows full 3D positioning; basic mode uses simplified snapping.
5. **Own house only for editing** — Cannot edit decorations in someone else's house.
6. **Layout compatibility** — Layouts may not load correctly if decorations have been removed from the game.
7. **Neighborhood initiatives** — Shared community goals; progress is collective, not individual.
8. **Hardware events** — Purchasing catalog items requires user interaction (hardware clicks).
