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)Built for:• survival games• dungeon crawlers• action RPGs• horde combat• voxel combat systemsFeatures:• Functional AI LOD (logic + animation + audio scaling)• Object pooling with gradual preloading• Procedural animation without Animator Controller• Modular architecture with event callbacks• Optimized Drag the prefabs into your scene and integrate scalable combat AI immediately.System Requirements• NavMesh SystemIncluded Scripts • NpcController• NpcBrain• NpcConfig• NpcNavigation• NpcCombat• NpcHealth• NpcAnimationController• NpcAudioController• NpcVFXController• NpcPool• NpcLOD• GameEvents• HealthSystem exampleIncluded 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.
