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).

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.
