Expand description

Debug drawing callbacks and options (b2DebugDraw). C carries function pointers plus option fields in one struct initialized by b2DefaultDebugDraw; the Rust port is a trait where every method has a default body matching those defaults (draw callbacks default to no-ops so an implementation can supply only the subset it cares about, options default to the b2DefaultDebugDraw values). Callbacks receive world coordinates: in large world mode Pos/WorldTransform translations are double precision so they stay accurate far from the origin.

Provided Methods§

Source

fn draw_polygon( &mut self, transform: WorldTransform, vertices: &[Vec2], color: HexColor, )

Draw a closed polygon provided in CCW order (DrawPolygonFcn).

Source

fn draw_solid_polygon( &mut self, transform: WorldTransform, vertices: &[Vec2], radius: f32, color: HexColor, )

Draw a solid closed polygon provided in CCW order (DrawSolidPolygonFcn).

Source

fn draw_circle(&mut self, center: Pos, radius: f32, color: HexColor)

Draw a circle (DrawCircleFcn).

Source

fn draw_solid_circle( &mut self, transform: WorldTransform, center: Vec2, radius: f32, color: HexColor, )

Draw a solid circle (DrawSolidCircleFcn).

Source

fn draw_solid_capsule(&mut self, p1: Pos, p2: Pos, radius: f32, color: HexColor)

Draw a solid capsule (DrawSolidCapsuleFcn).

Source

fn draw_line(&mut self, p1: Pos, p2: Pos, color: HexColor)

Draw a line segment (DrawLineFcn).

Source

fn draw_transform(&mut self, transform: WorldTransform)

Draw a transform; choose your own length scale (DrawTransformFcn).

Source

fn draw_point(&mut self, p: Pos, size: f32, color: HexColor)

Draw a point (DrawPointFcn).

Source

fn draw_string(&mut self, p: Pos, s: &str, color: HexColor)

Draw a string in world space (DrawStringFcn).

Source

fn draw_bounds(&mut self, aabb: Aabb, color: HexColor)

Draw a bounding box (DrawBoundsFcn). With double precision enabled, the single precision bounding box gets increasing padding when moving far from the origin.
