A packet-based structure system for Minecraft — powered by PacketBlocks.
Structures lets you create, manage, and display packet-based builds that can be shown or hidden for specific players — all without changing the actual world.

✨ Features

• ️ Create Packet-Based Structures — Build entirely virtual structures that exist only as packets.
• Per-Player Visibility — Show or hide structures for individual players on demand.
• ⚡ Instant Updates — No world edits or block updates — everything is rendered client-side.
• Custom Animations — Add show/hide animations to structures for smooth transitions.
• In-Game Editor — Build structures block-by-block using an intuitive edit mode.
• Copy & Duplicate — Clone existing structures and paste them anywhere with automatic rotation.
• Integration Ready — Perfect for developers wanting to display custom visuals, events, or world overlays.

Example Uses

• Show private or team-only structures.
• Create holographic arenas, minigame visuals, or build previews.
• Display world regions, borders, or effects visible to certain players only.
• Build dynamic event structures that appear and disappear with animations.
• Preview builds before placing them in the real world.
