minimap-system

A Unity minimap works by using a dedicated orthographic camera that renders the scene to a RenderTexture, which is then displayed on a UI panel. This approach supports entity icons and fog of war while maintaining zero GC allocation per frame.

Yes, the Unity minimap system supports displaying the RenderTexture in both UI Toolkit and UGUI panels. This allows you to integrate the real-time spatial overview into your existing UI layout without compatibility conflicts.

Yes, you can add fog of war and entity icons to your Unity minimap. The system provides optional fog of war for revealing explored areas and displays icons for players, enemies, and objectives to enhance situational awareness.

The best way to implement minimap zoom in Unity is by adjusting the orthographic camera's properties tied to the RenderTexture. This system supports dynamic zooming, allowing players to scale the minimap view to their preference.

Yes, you need Unity 6 or higher to use this minimap system. It is designed to support any render pipeline while focusing on zero GC allocation per frame for the RenderTexture approach, ensuring performance across RPG and RTS genres.

An orthographic camera for a Unity minimap accurately captures spatial relationships and top-down terrain geometry into a RenderTexture. This method avoids manual coordinate mapping required by UI overlays, directly supporting features like fog of war and dynamic zoom.
