Elys Awareness brings composable awareness pipelines to Unreal Engine 5.8.

Gather candidate actors, filter them, combine scoring rules and resolve a result for each gameplay channel. Your gameplay systems decide what happens next.

Use the Blueprint-first API to compose your own awareness systems.

Ready-to-use samplers, filters and scorers cover common detection and selection rules. Combine the supplied blocks or add your own implementations in Blueprint and C++.

Two included use cases demonstrate the framework.

Interaction provides contextual actions and prompts, with bonus Hold, Mash, alternating-input, directional QTE, timing and rhythm challenges.

Targeting provides focus, lock, aim-based selection, nearest-target selection and cycling.

The included Blueprints and UMG widgets can be used as shipped or customized for your game. Change colors, layout and feedback, reuse the demo's behavior, or compose your own rules, gameplay responses and presentation.

Interaction and targeting remain independent; their controls and priorities are your game-design choices.

IMPORTANT SCOPE

• Unreal Engine 5.8 only

• Windows 64-bit only

• Required engine plugin: Enhanced Input, built into Unreal Engine and enabled automatically; no external marketplace plugin dependency
