UIHotkeyGroup - jimdroberts/FishMMO GitHub Wiki

A small UI container for a single hotkey slot that groups the UIHotkeyButton, its label, and cooldown slider. Initializes and cleans up links between the button and the cooldown mask.

• public UIHotkeyButton Button

  The UIHotkeyButton instance contained by this group.

• public TMP_Text Label

  Text component showing the hotkey label/key.

• public Slider CooldownMask

  Slider used by the button to visually indicate cooldown progress.

• private void Awake()

  Called on initialization. Links the CooldownMask to the Button and resets its value to 0.

• private void OnDestroy()

  Called when the group is destroyed. Unlinks the CooldownMask from the Button and resets the HotkeySlot.

1. Create a hotkey group prefab containing a UIHotkeyButton, TMP_Text label, and a Slider for cooldown.
2. Assign references to the Button, Label, and CooldownMask in the prefab inspector.
3. Instantiate the prefab under a UIHotkeyBar to populate hotkey slots.

var group = Instantiate(hotkeyGroupPrefab, parent).GetComponent<UIHotkeyGroup>();
group.Label.text = "1"; // or use UIHotkeyBar to set labels

// UIHotkeyGroup will automatically link the slider to the button for cooldown visuals.

• Keep visual elements lightweight; the cooldown slider is updated frequently and should not cause GC churn.
• Use a consistent prefab layout so labels and icons align across all hotkeys.
• Rely on UIHotkeyBar.AddHotkeys to initialize slots; avoid manual runtime manipulation unless necessary.
