# physics engine _for hecs_

Port of `bevy_rapier2d` to hecs ECS.

## WARNING

- This code requires hecs fork with entity change tracking: 

## Example

```rust

use hecs_rapier as physics;

use hecs::World;

let mut world = World::new();

/* Create structures necessary for the simulation. */

let gravity = vector![0.0, -9.81];

let integration_parameters = physics::IntegrationParameters::default();

let mut physics_pipeline = physics::PhysicsPipeline::new();

let mut island_manager = physics::IslandManager::new();

let mut broad_phase = physics::BroadPhase::new();

let mut narrow_phase = physics::NarrowPhase::new();

let mut joint_set = physics::JointSet::new();

let mut joints_entity_map = physics::JointsEntityMap::default();

let mut ccd_solver = physics::CCDSolver::new();

// let physics_hooks = ();

let event_handler = ();

let mut modification_tracker = physics::ModificationTracker::default();

while running {

        physics::attach_bodies_and_colliders(&mut world);

        physics::create_joints(&mut self.world, &mut joint_set, &mut joints_entity_map);

        physics::finalize_collider_attach_to_bodies(&mut world, &mut modification_tracker);

        physics::prepare_step(&mut world, &mut modification_tracker);

        while need_to_step {

            physics::step_world(

                &mut world,

                &gravity,

                &integration_parameters,

                &mut physics_pipeline,

                &mut modification_tracker,

                &mut island_manager,

                &mut broad_phase,

                &mut narrow_phase,

                &mut joint_set,

                &mut joints_entity_map,

                &mut ccd_solver,

                &event_handler,

            );

        }

        physics::collect_removals(&mut world, &mut modification_tracker);

        next_frame().await;

        world.clear_trackers();

}
