General AKO - Stealth Gameplay Systems| (AKO) | AI, Grass Hide, Throw & Takedown

A full, ready-to-use stealth gameplay toolkit for Unreal Engine 5 — free.
Build believable stealth experiences quickly: AI perception (sight/hearing/touch), patrols on splines, hide-in-grass mechanics, throwable noise items with a custom throw widget, stealth takedowns with a target widget, player crouch + IK fixes, health bar UI, and polished alert logic.
Everything is implemented in Blueprints only, includes demo maps, animations, materials, and is ready to plug into your project.

What’s included

  • Blueprint Systems

    • AI Perception setup (sight, hearing, touch) and sample Behavior logic.

    • Patrol AI on Spline (smooth path following).

    • Advanced Alert / Warning logic (dynamic caution level, exclamation indicator).

    • Hide-in-Grass system (interactive grass detection to block AI sight).

    • Pickup & Throw System (pickup marker, inventory limit feedback, trajectory preview).

    • Throw Widget UI for selecting items and throwing (Blueprint-only widget).

    • Noise/Distraction system — thrown items create sound events the AI investigates.

    • Stealth Takedown System + Target Widget (lock target, play takedown animations, handle interrupts).

    • Player mechanics: built-in crouch integration and IK foot fix blueprint for smoother crouch animations.

    • Player Health System with Progress Bar UI (simple, modular).

Assets

  • Demo level(s) showing each system (patrols, grass, throw & distraction, takedown).

  • Animations used in the demos (takedowns, crouch transitions, idle, search).

  • Materials (grass material, simple UI materials).

  • Widget assets (throw selector, target widget, health bar).

  • Example sound events for throwable items (impact + unique SFX per item).
