BetterCollider2D is a lightweight Unity tool that allows you to assign multiple 2D colliders to a GameObject and switch between them automatically based on the currently active sprite or animation frame.
Automatically generates colliders from sprites, so you don’t have to create them manually.
It's the perfect solution for 2D character animation where each frame needs a different hitbox or shape, without writing complex collider logic manually.
Designed to be easy to use, performance-friendly, and compatible with any 2D project using SpriteRenderer or Animator.
Includes a demo scene, sample slime character, and full documentation to get you started right away.
