CharacterController2D
A Unity 2D character controller component that mimics the behavior and API of Unity's built-in CharacterController.
What is CharacterController2D?
CharacterController2D is a Unity component for 2D games that replicates the functionality of Unity's built-in CharacterController in a 2D environment. It provides a move-based API for handling character movement, collision detection, and platform interactions, solving the problem of building reliable and precise 2D character controllers without reinventing physics logic.
Unity developers creating 2D games, particularly those building platformers or action games requiring precise character movement and collision handling.
Developers choose CharacterController2D because it offers a familiar, easy-to-use API similar to Unity's standard tools, reduces the complexity of implementing 2D physics from scratch, and includes features like one-way platform support and debug visualization for faster iteration.
Overview
CharacterController2D is a Unity component designed for 2D games, providing a robust and familiar API similar to Unity's built-in CharacterController. It handles complex collision detection, platform interactions, and movement physics, offering a solid foundation for building precise and responsive 2D character controllers.
Key Features
- Move Method — Accepts a delta movement vector for frame-by-frame control, mirroring Unity's CharacterController API.
- Collision Detection — Uses configurable raycasting for accurate collisions with platforms and obstacles.
- One-Way Platforms — Supports one-way platforms (requiring EdgeCollider2Ds) with dedicated layer masking.
- Trigger Events — Configurable trigger interaction layers for onTriggerEnter/Stay/Exit events.
- Debug Visualization — Draws debug rays in the editor to fine-tune ray resolution for platform sizes.
- Event Notifications — Provides onControllerCollidedEvent for custom collision handling.
Philosophy
CharacterController2D prioritizes simplicity and familiarity, offering a straightforward setup and API that Unity developers already understand, while ensuring reliable 2D physics interactions.
