This struct holds callbacks you can implement to draw a Box2D world. Callbacks receive world coordinates. In large world mode the translation is double precision so it stays accurate far from the origin. Shift into your own camera frame inside the callbacks. Initialize with b2DefaultDebugDraw. @ingroup world

Fields

DrawPolygonFcn: Option<unsafe extern "C" fn(transform: b2WorldTransform, vertices: *const b2Vec2, vertexCount: c_int, color: b2HexColor, context: *mut c_void)>

Draw a closed polygon provided in CCW order.

DrawSolidPolygonFcn: Option<unsafe extern "C" fn(transform: b2WorldTransform, vertices: *const b2Vec2, vertexCount: c_int, radius: f32, color: b2HexColor, context: *mut c_void)>

Draw a solid closed polygon provided in CCW order.

DrawCircleFcn: Option<unsafe extern "C" fn(center: b2Pos, radius: f32, color: b2HexColor, context: *mut c_void)>

Draw a circle.

DrawSolidCircleFcn: Option<unsafe extern "C" fn(transform: b2WorldTransform, center: b2Vec2, radius: f32, color: b2HexColor, context: *mut c_void)>

Draw a solid circle.

DrawSolidCapsuleFcn: Option<unsafe extern "C" fn(p1: b2Pos, p2: b2Pos, radius: f32, color: b2HexColor, context: *mut c_void)>

Draw a solid capsule.

DrawLineFcn: Option<unsafe extern "C" fn(p1: b2Pos, p2: b2Pos, color: b2HexColor, context: *mut c_void)>

Draw a line segment.

DrawTransformFcn: Option<unsafe extern "C" fn(transform: b2WorldTransform, context: *mut c_void)>

Draw a transform. Choose your own length scale.

DrawPointFcn: Option<unsafe extern "C" fn(p: b2Pos, size: f32, color: b2HexColor, context: *mut c_void)>

Draw a point.

DrawStringFcn: Option<unsafe extern "C" fn(p: b2Pos, s: *const c_char, color: b2HexColor, context: *mut c_void)>
