Audio Feedback on POI Selection
Plays audio cues when users interact with Points of Interest to enhance feedback. Can be extended for status-based cues like “Available”, “Sold”, and “Reserved”.
Block Input Propagation on UI Elements
Prevents unintended camera movement or interactions when the user starts a touch or mouse drag on a UI element (like a panel or border). Blocks input from reaching the PlayerController by using overrides (OnMouseButtonDown / OnTouchStarted). This ensures the Input system doesn’t respond when the user is interacting with the interface.
Two-Handle Range Slider
Custom dual-handle range slider for defining both lower and upper bounds. This widget features snapping logic that utilizes normalized values for precise filtering. Replaces Unreal Engine’s default single-handle slider, which only supports an upper limit.
Multilingual Localization Setup
Localization Setup for English as the source language and support for French and German as target translations.
Optimized POI Display with Common Tree View
Replaced custom POI list with Unreal’s Common Tree View for improved performance and scalability. Supports hierarchical organization, built-in selection handling, and native list virtualization for faster rendering of large POI sets. Key Advantages:
Dollhouse View for 3D Floor plans
Inspect 3D room layouts and unit features up close.
Common UI Menu Hierarchy & Input Routing
Initial implementation explored using Unreal’s Common UI framework for layered menu navigation and input handling across widgets. The feature was put on hold due to AVE II’s single-platform focus and lack of clear documentation, which would hinder usability for developers. The current UI framework already offers adequate customization and can be easily expanded further.
