Ids and names

ay2d_parameter_id, ay2d_part_id, ay2d_mesh_id

const char *ay2d_parameter_id(const ay2d_model *m, uint32_t i);
const char *ay2d_part_id(const ay2d_model *m, uint32_t i);
const char *ay2d_mesh_id(const ay2d_model *m, uint32_t i);

The id the rig uses, such as ParamAngleX. These are what motion and expression files refer to. NULL past the count. Thread: any.

ay2d_parameter_name, ay2d_part_name, ay2d_mesh_name

const char *ay2d_parameter_name(const ay2d_model *m, uint32_t i);
const char *ay2d_part_name(const ay2d_model *m, uint32_t i);
const char *ay2d_mesh_name(const ay2d_model *m, uint32_t i);

The name to show a person, such as "Angle X". Falls back to the id when the file has none. Use these in a UI, never for lookups. Thread: any.

ay2d_parameter_index

int32_t ay2d_parameter_index(const ay2d_model *m, const char *id);

The index of the parameter with this id, or -1. Look ids up once at load and drive by index. Thread: any.
