Drag-and-drop 2D platformer toolkit: advanced player controller, autonomous enemy patrols, and reactive AI with a vision cone and a five-state behavior machine. Side-scroller and top-down, no coding.Build your 2D platformer faster with a complete, drag-and-drop toolkit that combines three production-ready systems: an advanced player controller, an autonomous enemy patrol system, and a reactive perception AI - all configured entirely from the Inspector. No coding required to get a working result.Every script is heavily commented and beginner-friendly, yet flexible enough to drop into a real project. Two pre-configured demo scenes (Side-Scroller and Top-Down) let you tune every parameter and dial in the exact game feel you want.WHAT'S INSIDE- Player Controller - a feature-rich 2D character controller with damped movement, multi-jump, coyote time, jump buffering, variable jump height, dashing, ladder climbing, wall slide, and wall jump. Physics runs in FixedUpdate for stable, frame-rate-independent motion.- Enemy Patrol - autonomous patrol for both Side-Scroller (ledge and wall detection) and Top-Down (fixed waypoints or random roaming) games, with smooth rotation and runtime fallbacks so enemies work even before everything is wired.- Reactive AI (Smart Senses) - adds a vision cone, proximity sense, and optional line-of-sight blocking on top of any patroller, driving a five-state behavior machine: Patrol → Suspicious → Chase → Search → Return.FEATURES1. Plug-and-play: attach a script and tune everything from the Inspector - auto-setup wires and references for you.2. Two enemy modes (Side-Scroller and Top-Down) with fixed or random patrol patterns.3. Reactive enemy AI with vision, proximity detection, line-of-sight occlusion, and a five-state machine.4. Advanced player feel: wall jump, dash, coyote time, jump buffering, and tunable gravity.5. UnityEvents throughout: hook in sound, VFX, and UI from the Inspector with no code.6. Live Scene: view gizmos for vision cones, ranges, and ground/ladder/wall checks.7. Context-aware custom Inspector that shows only the fields relevant to your Game Type.8. Two pre-configured demo scenes and full technical documentation included.Please note: these scripts use Unity's legacy Input Manager. Set Active Input Handling to "Input Manager (Old)" or "Both" in Player Settings - a one-line change, covered in the documentation.- Render Pipelines: Built-in, URP, and HDRP (2D).- Unity Version: 2021.3 LTS or newer; tested on Unity 6 (6000.x).- Scripting Backend: Mono or IL2CPP.- Dependencies: None - uses only built-in UnityEngine 2D physics.- Input: Legacy Input Manager (Input.GetAxisRaw / GetKeyDown). Requires Active Input Handling = "Input Manager (Old)" or "Both".- Required components: Rigidbody2D and Collider2D on each controlled object; SpriteRenderer on the player for sprite flipping.Included scripts:- EnemyPatrol2D.cs: core autonomous patrol (Side-Scroller and Top-Down).- EnemySmartSenses.cs: perception + five-state AI machine (companion, auto-requires EnemyPatrol2D).- PlayerMovement.cs: advanced 2D platformer controller.- Editor/CustomInspector.cs: context-aware custom Inspector for EnemyPatrol2D.Also includes: Side-Scroller and Top-Down demo scenes (pre-configured) and a technical documentation PDF (v2.0).All code is fully readable, heavily commented, and designed to be modified or extended.
