All Features:

- Generates 2D chains and ropes.

- Features a 2D curve editor for chain generation.

- Supports chain generation in both editor and runtime modes.

- Includes an object pooler for optimized chain generation at runtime.

- Includes profiles, which are ScriptableObjects that store chain properties.

- Includes scripts for sound, cutting, and dragging.

- Includes sprites for both chains and ropes.

- Includes 2 simple sound effects.

- Provides an option to automatically fade chain segments once they are cut.

- Provides an option to connect other rigidbodies to the chain.

- Provides an option to lock the anchor point.

- Provides an option to loop the 2D curve.

Important:

- This tool is based on the HingeJoint2D component.

- The rope is created using the LineRenderer component.

- There is no editor for the 2D curve during runtime.

- Enhanced 2D curve editor.

How to reduce HingeJoint2D errors?

In Unity's menu bar, go to Edit > Project Settings > Physics2D, then increase the Velocity and Position Iterations. Keep in mind that a higher number of iterations will improve accuracy but also increase processing overhead.
