A complete, modular 2D platformer foundation: a character controller with AAA game feel (coyote time, wall jump, dash), enemies, health, collectibles, platforms and HUD. Build levels, not boilerplate.ender pipeline agnostic: pure C# gameplay code, sprites and UGUI/TextMeshPro UI - no custom shaders or materials. Works out of the box in Built-in RP and URP (incl. 2D Renderer). Demo sprites use the default unlit sprite material; switch them to Sprite-Lit-Default to react to URP 2D lights. HDRP: code works, but HDRP is not intended for 2D - use Built-in or URP. No conversion steps required.2D Platformer Toolkit gives you everything a classic side-scrolling platformer needs — so you can start building levels on day one.The heart of the package is a character controller tuned like the genre's best: a designer-friendly jump model (set jump height and time-to-apex — gravity is derived for you), coyote time, jump buffering, variable jump height, apex hang-time, snappy turn acceleration, corner correction, wall slide & wall jump, dash, crouch, ladder climbing, one-way platform drop-through, squash & stretch and invulnerability flicker. Every assist can be toggled and tuned in the inspector.Around it you get complete gameplay systems: health & contact damage with knockback, hit-stun and freeze-frames; stompable walking and flying enemies; coins, keys and health pick-ups; checkpoints with automatic respawn; moving, falling and one-way platforms; springs, kill zones, locked doors, projectile turrets, level exits, a follow camera, pause handling and a ready HUD (coin counter + heart display).Fully customizable and built to be extended. Every value is exposed with tooltips, every system fires UnityEvents (hook up sounds and particles without code) plus C# events for programmers. Clean namespaced API, XML-documented, in its own assembly definition. The Collectible base class and IDamageable interface make new pick-ups and damage sources a few lines of code.Ideal for classic action platformers, GBA-style games, metroidvanias and precision platformers — but the motor is input-agnostic, so AI characters and cutscenes can drive it too.Includes a playable demo level exercising every component, a Getting Started guide with recipes, and first-party pixel-art sprites.
