minemap-events-and-picking

MineMap event subscription handles map events and 3D object picking by providing a unified interface using map.on, map.once, and map.off. It ensures reliable lifecycle management for both 2D layers and 3D scenes.

The best way to manage event listener lifecycles is using layer-level event proxies with selective binding. This approach reduces overhead and improves responsiveness when subscribing to events across MineMap layers.

Yes, MineMap supports GPU-based picking for 3D scenes. The unified picking workflows combine GPU-based picking and feature queries to handle interactions across both 2D layers and 3D scenes.

Yes, you can build interactive UIs and debug tools using MineMap event hooks. The system provides demo-oriented guidance for creating interactive tools, editors, and debug utilities.

Layer event subscription causes performance overhead if not using selective binding. Applying layer-level event proxies reduces overhead and improves responsiveness during 2D and 3D interactions.

To query features from a clicked layer in MineMap, register a click event on the target layer. The event hook fetches the first feature and allows you to display a popup with the result.
