Übersicht

Um ohne Server-Neustarts oder Reconnects konsistente Inventare bei GameRule-Änderungen zu gewährleisten, implementiert die Mod das Payload StackSizeLimitSyncPayload.

• Bezeichner: stack-size-adjuster:sync_limit
• Richtung: Server an Client (S2C)
• Auslösung: Bei ServerPlayConnectionEvents.JOIN und Aufrufen von StackSizeManager.setLimits.

Dynamische Inventar-Aktualisierung

Beim Aktualisieren der Limits iteriert StackSizeManager.setLimits über alle Spieler:

for (ServerPlayer player : server.getPlayerList().getPlayers()) {
    ServerPlayNetworking.send(player, payload);
    if (player.containerMenu != null) {
        player.containerMenu.broadcastFullState();
    }
    if (player.inventoryMenu != null && player.containerMenu != player.inventoryMenu) {
        player.inventoryMenu.broadcastFullState();
    }
}
