Scalable melee NPC AI framework with Utility AI, FSM behaviors, LOD, pooling, and procedural animation for combat systems and large enemy counts.This package is render-pipeline independent because it contains gameplay logic, scripts, and prefabs only. Compatible with Built-in, URP, and HDRP. No custom shaders or render-dependent materials are required.NEXUS. combines Utility AI, FSM behaviors, functional LOD, object pooling, and procedural animation into one modular framework optimized for performance.Includes 3 behavior modes:• Utility AI (context-based decision making)• Persecutor (infinite chase FSM)• Territorial (FSM with leash system)Included NPC skins are fully customizable and can be easily replaced with your own characters and modelsBuilt for:• survival games• dungeon crawlers• action RPGs• horde combat• voxel combat systemsFeatures:• Functional AI LOD (logic + animation + audio scaling)• Object pooling with gradual preloading• Fully editable procedural animation system without Animator Controller• Customize arm and leg movement, animation speeds, angles, and motion parameters• Modular architecture with event callbacks• OptimizedDrag the prefabs into your scene and integrate scalable combat AI immediately.Supported Unity Versions: 2022.3 LTS and newer.System Requirements• NavMesh SystemIncluded Scripts• NpcController• NpcBrain• NpcConfig• NpcNavigation• NpcCombat• NpcHealth• NpcAnimationController• NpcAudioController• NpcVFXController• NpcPool• NpcLOD• GameEvents• HealthSystem exampleFully editable procedural animation system• Adjustable animation speeds• Editable arm and leg movement parameters• Customizable movement angles and ranges• Fine-tune animation behavior without Animator Controllers• Easily adapt animations for different enemy types and combat styles• NPC skins included• Fully editable and replaceable character skins• Easily customize or swap models and visual appearances• Compatible with custom character assetsIncluded Prefabs• NPC_Persecutor• NPC_Territorial• NPC_UtilityAI• LOD versions includedOpenAI was used as an assistance tool during parts of the package creation process, bug fixing in some scripts.All game systems, architecture, AI logic, FSM design, Utility AI decision systems, pooling, LOD systems, procedural animation logic, and implementation were fully designed, coded, integrated, tested, and validated manually by the publisher.
