# Floor Restriction

A **floor-level restriction** limits access to specific floors of an elevator or elevators. If the restriction check returns `false`, the specified floors become inaccessible while others remain accessible.

{% hint style="info" %}
You can find all of the examples in `no-elevators/restrictions/examples` folder.
{% endhint %}

### Example

***

```lua
local API = exports["no-elevators"]

local function isAdmin(source)
    return IsPlayerAceAllowed(source, "elevators.admin")
end

--In this example:
-- admin, admin2, admin3, and admin4 are elevator IDs.
-- Each floor list (e.g., {1, 2, 3} or 1) defines the restricted floors by their index.
-- isAdmin determines whether the user has access.

---@param floors table<string, table<number> | number>
---@param controller fun -> boolean
API:AddFloorRestriction({
    admin = {1, 2, 3},
    admin2 = {1, 2, 3},
    admin3 = {1, 2, 3},
    admin4 = 1
}, isAdmin)

------------------------------------------------------------------------------------------------------------

--In this example:
-- "admin2" is the elevator ID.
-- 1 or {2, 3, 4} specifies the restricted floors by their index.
-- isAdmin determines whether the user has access.

---@param elevatorId string
---@param floors table<number> | number
---@param controller fun -> boolean
API:AddFloorRestriction("admin2", 1, isAdmin)
API:AddFloorRestriction("admin2", {2, 3, 4}, isAdmin)
