## Features

You can simply add a `VerletPoint` component on any entity with a

`Transform` and the verlet physics will apply.

Connect points using `VerletStick` to constrain movement (see

[examples](./examples)).

Lock some points by adding the `VerletLocked` component on a `VerletPoint`

entity.

Customize *friction* and *gravity* with the `VerletConfig` resource.

> Works in 2D and 3D.

## Cargo features

1. `debug`

This feature will add a *system* drawing debug lines for every stick using

bevy gizmos

## Examples

### 2D

1. 2D Line

   `cargo run --example 2d_line --features "debug"`
