local aimKey   = cat:add_keybind("Aim Key", 0, 0)
local name     = cat:add_input("Player Name", "", 64)

cat:add_separator()
cat:add_label("Press Apply to read every value at once.")

-- A button that reads the entire state on demand. This is the simplest way to
-- inspect what the UI is currently holding without wiring change callbacks
-- everywhere.

    print("aim key     :", aimKey:get_key())
    print("player name :", name:get())
end)

-- Gate the "Aim Key" picker behind the "Enable" toggle so it only shows up
-- when the rest of the script is active. set_visible keeps the keybind alive

    Enum.KeybindMode.PressAndHold, function(k)
        state.bindKey = k
        refresh()
    end)

-- Separate channel from the rebind callback above.
bind:on_activated(function(active)
    print("aim", active and "ACTIVE" or "idle")
end)

-- Master toggle hides the dependent controls when off. set_visible keeps the
-- controls alive, so their state survives a hide/show cycle.
local function setCoreVisible(v)
    sens:set_visible(v)
    partDD:set_visible(v)
    bind:set_visible(v)
end

enabled:on_changed(function(v) setCoreVisible(v) end)

### Dropdown Indexing and Selection

Source: https://docs.rbxcli.dev/tutorials/api-usage/rbxcli-gui/dropdowns

Demonstrates how to add a dropdown, get and set its index, and retrieve the selected option. Shows how index 0 represents no selection and how out-of-range indices raise errors.

```lua
local mode = cat:add_dropdown("Mode", { "Alpha", "Beta", "Gamma" }, 1)

mode:get_index()    -- 1
mode:get_selected() -- "Alpha"

mode:set_index(0)

### Idempotent Setup Pattern for Script Reloads

Source: https://docs.rbxcli.dev/tutorials/api-usage/rbxcli-ui-legacy/lifecycle-and-cleanup

Implements the essential reload-safe pattern by removing any existing tab with the same name before adding a new one. This prevents duplicate tabs from accumulating during development reloads.

```lua
local TAB_NAME = "My Script"

pcall(function() rbxcli_ui.remove_tab(TAB_NAME) end)

local tab = rbxcli_ui.add_tab(TAB_NAME, "code")
local main = tab:add_category("Main", 320)

main:add_toggle("Enable", false, function() end)
main:add_slider("FOV", 0, 180, 90, false, function() end)
```

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

### Handling Destroyed Control Proxies

Source: https://docs.rbxcli.dev/tutorials/api-usage/rbxcli-ui-legacy/lifecycle-and-cleanup

Demonstrates the behavior of a destroyed control proxy. Subsequent calls to `:get()` return nil, and setters become silent no-ops after an initial warning.

```lua
local tog = cat:add_toggle("Flag", false)
tog:destroy()

tog:enable()       -- silent no-op, warns once
print(tog:get())   -- nil
```

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

### GuiKeybind Fields and Methods

Source: https://docs.rbxcli.dev/datatypes/GuiKeybind

This snippet details the fields and methods available for the GuiKeybind datatype, including how to get and set properties, and how to register callbacks for activation and changes.

```APIDOC
## GuiKeybind

struct
Keybind proxy returned by `GuiCategory:add_keybind`. Carries a bound key and an activation mode.

Remarks
Two independent event streams: the change callback fires on rebind; `on_activated` fires on activation-state transitions. Most feature code wants `on_activated`.

## Fields (16)
category:GuiCategory?destroy:() -> ()get_key:() -> KeyCodeget_mode:() -> KeybindModeis_active:() -> booleanis_destroyed:() -> booleanis_visible:() -> booleankind:ControlKindlabel:stringname:stringon_activated:(callback: (active: boolean) -> ()) -> GuiConnectionon_changed:(callback: (key: number) -> ()) -> GuiConnectionset_key:(key: KeyCode) -> ()set_label:(text: string) -> ()set_mode:(mode: KeybindMode) -> ()set_visible:(visible: boolean) -> ()

## Fields
`category` : GuiCategory?
Back-reference to the owning category. `nil` after the owning tab is gone.

`destroy` : () -> ()
Marks the keybind destroyed.

`get_key` : () -> KeyCode
Returns the bound `KeyCode`.

`get_mode` : () -> KeybindMode
Returns the activation mode.

`is_active` : () -> boolean
Returns the current latched activation state.
Remarks
In `Toggle` mode it is the latched-on flag. In `PressAndHold` mode it mirrors the key's down-state.

`is_destroyed` : () -> boolean
Returns the destroyed flag.

`is_visible` : () -> boolean
Returns the visibility flag.

`kind` : ControlKind
Always `Enum.ControlKind.Keybind`.

`label` : string
Current label text.

`name` : string
Alias for `label`.

`on_activated` : (callback: (active: boolean) -> ()) -> GuiConnection
Registers an activation listener.
Remarks
Fires on activation-state transitions only, one event per transition rather than per frame the key is held. Independent of `on_changed`; disconnecting one channel does not affect the other.

`on_changed` : (callback: (key: number) -> ()) -> GuiConnection
Registers an additional rebind listener.
Remarks
Receives the raw integer key code, not a `KeyCode` enum value. Use `get_key()` if you want the typed value.

`set_key` : (key: KeyCode) -> ()
Sets the bound key.
Remarks
Fires the change callback on the next main-thread turn.

`set_label` : (text: string) -> ()
Replaces the label.

`set_mode` : (mode: KeybindMode) -> ()
Sets the activation mode.
Remarks
The UI mode picker updates in lockstep with the new value.

`set_visible` : (visible: boolean) -> ()
Shows or hides the keybind row.
```

### print

Source: https://docs.rbxcli.dev/libraries/globals

Prints its arguments to the VM output log. Multiple arguments are separated by tabs. Scalars are stringified the same way tostring would do it; tables are pretty-printed recursively.

```APIDOC
## print

### Description
Prints its arguments to the VM output log. Multiple arguments are separated by tabs. Scalars are stringified the same way `tostring` would do it; tables are pretty-printed recursively (Roblox Studio style) with cycle detection when the `core.luau.pretty_print` setting is enabled. Tables with an `__iter` metamethod are walked via `__iter` so their actual contents are emitted. With the setting off, behaves like the classic Luau `print` (each argument stringified via `tostring`).

### Method
() → ()

## GuiInput Methods

### Description
Provides methods to manage and retrieve information about a single-line text input.

### Methods

- **`destroy()`**
  Marks the input as destroyed.

- **`get_text()` -> `string`**
  Returns the current text content of the input field.

- **`is_destroyed()` -> `boolean`**
  Checks if the input has been marked as destroyed.

- **`is_visible()` -> `boolean`**
  Checks if the input is currently visible.

- **`on_changed(callback: (value: string) -> ()) -> GuiConnection`**
  Registers a callback function to be executed when the input's value changes. The callback fires on commit, not per keystroke.

- **`set_label(text: string)`**
  Sets or replaces the label text for the input.

- **`set_text(text: string)`**
  Sets the text content of the input field. This action fires the change callback on the next main-thread turn.
