# bevy_2d_box_physics

A 2D box-collision physics engine for use with the bevy engine

## Usage
For the physics to work the `PhysicsPlugin` must be added. For adding
forces/velocity to objects you can add the `PhysicsBundle` and for collisions
(only collisionboxes are and will be supported) there is the `CollisionBundle`.
Sensors, which lets us get information when two objects overlap can also be
added with the `SensorBundle`. A very simple example can be seen below:
```rust
use bevy::prelude::*;
use bevy_2d_box_physics::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugin(PhysicsPlugin)
        .add_startup_system(setup)
        .run();
}

fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
    commands.spawn_bundle(PhysicsBundle {
        rigidbody: RigidBody::Dynamic,
        ..default()
    })
    .insert(CollisionBundle {
        collision_box: CollisionBox(16.0, 16.0),
        collision_layers: CollisionLayers {
            layer_id: 0,
            collides_with_ids: vec![0, 1],
        },
        ..default()
    })
}
```
(Note that this doesn't do much as there are no textures, but hopefully you get
the idea)
