Bevy versions

| bevy_verlet | bevy | |---------------|-----------| | 0.1.x | 0.5.x | | 0.2.x | 0.6.x | | 0.3.x | 0.7.x | | 0.4.x | 0.8.x | | 0.5.x | 0.9.x | | 0.6.x | 0.11.x |

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.

Cargo features

1. debug

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