Struct Collision 

pub struct Collision;

Zero-sized type that hosts collision detection functions.

All methods are static (no self receiver) and are used by the #[goud_api] proc-macro to auto-generate #[no_mangle] extern "C" FFI wrappers. The free functions below delegate to these methods.

Implementations

impl Collision

pub fn aabb_aabb( center_a: Vec2, half_extents_a: Vec2, center_b: Vec2, half_extents_b: Vec2, ) -> Option<Contact>

Tests collision between two axis-aligned bounding boxes.

pub fn circle_circle( center_a: Vec2, radius_a: f32, center_b: Vec2, radius_b: f32, ) -> Option<Contact>

Tests collision between two circles.

pub fn circle_aabb( circle_center: Vec2, circle_radius: f32, box_center: Vec2, box_half_extents: Vec2, ) -> Option<Contact>

Tests collision between a circle and an AABB.

pub fn point_in_rect(point: Vec2, rect_origin: Vec2, rect_size: Vec2) -> bool

Checks whether a point lies inside a rectangle.

pub fn point_in_circle( point: Vec2, circle_center: Vec2, circle_radius: f32, ) -> bool

Checks whether a point lies inside a circle.

pub fn aabb_overlap(min_a: Vec2, max_a: Vec2, min_b: Vec2, max_b: Vec2) -> bool

Fast boolean overlap test for two AABBs using min/max corners.

pub fn circle_overlap( center_a: Vec2, radius_a: f32, center_b: Vec2, radius_b: f32, ) -> bool

Fast boolean overlap test for two circles.

pub fn distance(a: Vec2, b: Vec2) -> f32

Returns the Euclidean distance between two points.

pub fn distance_squared(a: Vec2, b: Vec2) -> f32

Returns the squared Euclidean distance between two points.
