Notifications

Package: com.hypixel.hytale.server.core.util.NotificationUtil

Toast-style popup notifications with a primary message, secondary message, icon, item display, and style. Notifications are queued and each displays for 5 seconds.

Notification Styles

Style	Description
`NotificationStyle.Default`	Standard notification
`NotificationStyle.Danger`	Red/error styling
`NotificationStyle.Warning`	Yellow/warning styling
`NotificationStyle.Success`	Green/success styling

Sending Notifications

All methods on NotificationUtil are public static:

// simple notification to one player
NotificationUtil.sendNotification(
    playerRef.getPacketHandler(),
    Message.translation("mymod.item.received")
);

// with style
NotificationUtil.sendNotification(
    playerRef.getPacketHandler(),
    Message.translation("mymod.error.noPermission"),
    NotificationStyle.Danger
);

// with secondary message and icon
NotificationUtil.sendNotification(
    playerRef.getPacketHandler(),
    Message.translation("mymod.quest.complete"),
    Message.translation("mymod.quest.reward"),
    "Common/UI/Icons/QuestComplete",  // icon asset path
    null,                              // item (or ItemWithAllMetadata)
    NotificationStyle.Success
);

Targeting

// to all players in a world
NotificationUtil.sendNotificationToWorld(
    message, null, null, null, NotificationStyle.Default, store
);

// to all players on the server
NotificationUtil.sendNotificationToUniverse(message);
NotificationUtil.sendNotificationToUniverse(message, NotificationStyle.Warning);

The universe-wide methods iterate all worlds and all players within them.

Item Notifications

Notifications can display an item alongside the message:

NotificationUtil.sendNotification(
    playerRef.getPacketHandler(),
    Message.translation("mymod.item.crafted"),
    null,   // secondary message
    null,   // icon
    item,   // ItemWithAllMetadata
    NotificationStyle.Success
);

This is used internally by the crafting system and objective rewards.

HUD Visibility

The Notifications component can be toggled per-player via the HUD system:

// hide notification toasts for a player
hud.hideHudComponents(playerRef, HudComponent.Notifications);
