Module collision 

SDK Collision Detection API

Ergonomic Rust functions for 2D collision detection. Thin wrappers over crate::ecs::collision – pure math, no engine state required.

Example

use goud_engine::sdk::collision::{circle_circle, point_in_rect, distance};
use goud_engine::core::math::Vec2;

if let Some(contact) = circle_circle(
    Vec2::new(0.0, 0.0), 1.0,
    Vec2::new(1.5, 0.0), 1.0,
) {
    println!("Collision! Penetration: {}", contact.penetration);
}

assert!(point_in_rect(Vec2::new(5.0, 5.0), Vec2::new(0.0, 0.0), Vec2::new(10.0, 10.0)));
assert!((distance(Vec2::new(0.0, 0.0), Vec2::new(3.0, 4.0)) - 5.0).abs() < 0.001);

Structs

Collision

Zero-sized type that hosts collision detection functions.

CollisionResponse

Collision response configuration for impulse resolution.

Contact

Contact information from a collision.

Functions

aabb_aabb

Tests collision between two axis-aligned bounding boxes.

aabb_overlap

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

circle_aabb

Tests collision between a circle and an axis-aligned bounding box.

circle_circle

Tests collision between two circles (fastest collision test).

circle_overlap

Fast boolean overlap test for two circles.

distance

Returns the Euclidean distance between two points.

distance_squared

Returns the squared Euclidean distance between two points.

point_in_circle

Checks whether a point lies inside a circle.

point_in_rect

Checks whether a point lies inside a rectangle.
