# Description

Box2D 3.0 https://github.com/erincatto/box2d

Current commit: https://github.com/erincatto/box2d/commit/0e333fff0669afac5d9416e21f22adccada11755

Included platform binaries:

* windows_amd64_avx2

* windows_amd64_sse2

* linux_amd64_avx2(outdated)

* linux_amd64_sse2(outdated)

All binaries are build using the default settings.

All binaries are located in binaries directory if you want to use your own build of Box2D.

Defines for Box2D Constants:

* BOX2D_AVX2 (default: true)

* BOX2D_MAX_POLYGON_VERTICES (default: 8)

# Example:

```odin

package box2d_example

import b2 "odin-box2d"

import "core:fmt"

main :: proc()

{

    world_def := b2.default_world_def()

    world_def.gravity = b2.Vec2{0, -10}

    world_id := b2.create_world(&world_def)

    defer b2.destroy_world(world_id)

    

    ground_body_def := b2.default_body_def()

    ground_body_def.position = b2.Vec2{0, -10}

    ground_body_id := b2.create_body(world_id, &ground_body_def)

    ground_box := b2.make_box(50, 10)

    ground_shape_def := b2.default_shape_def()

    b2.create_polygon_shape(ground_body_id, &ground_shape_def, &ground_box)

    body_def := b2.default_body_def()

    body_def.type = .Dynamic

    body_def.position = b2.Vec2{0, 4}

    body_id := b2.create_body(world_id, &body_def)

    shape_def := b2.default_shape_def(0)

    circle := b2.Circle{{0, 0}, 1}

    b2.create_circle_shape(body_id, &shape_def, &circle)

    time_step: f32 = 1.0 / 60

    sub_steps: i32 = 4

    

    for i in 0..<60

    {

        b2.world_step(world_id, time_step, sub_steps)

        position := b2.body_get_position(body_id)

        angle := b2.body_get_angle(body_id)

        fmt.println(position, angle)

    }

}
