Functions

mk_box3d_debug_drawfunction

bool mk_box3d_debug_draw(mk_box3d_debug_draw_t adapter, b3WorldId world, mk_draw3d_ctx_t draw3d, const mk_box3d_debug_draw_desc *desc)

Draw authoritative Box3D state into an active draw3d context.

Destroy the Box3D world before destroying its adapter.

Parameter	Type	Description
adapter	mk_box3d_debug_draw_t	Value for adapter.
world	b3WorldId	Value for world.
draw3d	mk_draw3d_ctx_t	Value for draw3d.
desc	const mk_box3d_debug_draw_desc *	Configuration descriptor.

Returns True when the operation succeeds.

mk_box3d_debug_draw_attachfunction

bool mk_box3d_debug_draw_attach(mk_box3d_debug_draw_t adapter, b3WorldDef *world_def)

Install the adapter callbacks on a world definition before b3CreateWorld.

Existing debug-shape callbacks are rejected. An adapter may be attached once.

Parameter	Type	Description
adapter	mk_box3d_debug_draw_t	Value for adapter.
world_def	b3WorldDef *	Value for world def.

Returns True when the operation succeeds.

mk_box3d_debug_draw_createfunction

mk_box3d_debug_draw_t mk_box3d_debug_draw_create(void)

Draw create for the box3d debug.

Returns The resulting handle or value.

mk_box3d_debug_draw_desc_defaultfunction

mk_box3d_debug_draw_desc mk_box3d_debug_draw_desc_default(void)

Draw desc default for the box3d debug.

Returns The resulting value.

mk_box3d_debug_draw_destroyfunction

void mk_box3d_debug_draw_destroy(mk_box3d_debug_draw_t adapter)

Draw destroy for the box3d debug.

Parameter	Type	Description
adapter	mk_box3d_debug_draw_t	Value for adapter.

mk_box3d_transform_lerpfunction

b3WorldTransform mk_box3d_transform_lerp(b3WorldTransform previous, b3WorldTransform current, float alpha)

Interpolate a Box3D world transform for rendering.

Parameter	Type	Description
previous	b3WorldTransform	Value for previous.
current	b3WorldTransform	Value for current.
alpha	float	Value for alpha.

Returns The resulting value.

mk_box3d_transform_to_mkfunction

mk_transform mk_box3d_transform_to_mk(b3WorldTransform transform, b3Pos render_origin)

Convert a Box3D transform after shifting by render_origin.

Parameter	Type	Description
transform	b3WorldTransform	Value for transform.
render_origin	b3Pos	Value for render origin.

Returns The resulting value.
