class hkpConstraintListener {

= default; instead of {}

    gdt::FlagHandle getRevivalGameDataFlagHash() const { return mRevivalGameDataFlagHash; }
    void setRevivalGameDataFlagHash(const gdt::FlagHandle& value) {

nit: just pass the handle by value since it's an integer

bool ObjectLinkData::sub_7100D4EC40(Object* obj, ObjectLink* link, Object* dest) {

propagatePropsFromIncomingLinks? or something like that

ideally we shouldn't have any sub_xxx name

bool ObjectLinkData::sub_7100D4EF30(act::ActorConstDataAccess& accessor) {

IMO a placeholder name that describes what the function does is better than a sub_xxxx name

public:
    SEAD_ENUM(ConstrainedType,Parent,Child)

Consider adding spaces after each comma

src/KingSystem/Physics/Constraint/physConstraint.h line 26 at r2 (raw file):

    SEAD_ENUM(ConstrainedType,Parent,Child)

    typedef void (*ConstraintCallback)(void*, Constraint* constraint, bool a2);

using Callback = void (*)(void*, ...)

src/KingSystem/Physics/Constraint/physConstraint.cpp line 18 at r2 (raw file):

    : mConstraint(constraint), mCsOption(cs_option) {
    mDirection = quat->m_vec[0];
    mSleepingBodies[ConstrainedType::Parent] = parent;

is this mismatching because of the volatile mess from the ConstrainedType enum? If so that likely means they had a getSleepingBody(ConstrainedType) getter. getSleepingBody(ConstrainedType::Parent) = parent; would construct a ConstrainedType from the ConstrainedType::ValueType value, and then the enum to int volatile cast would happen inside the getter

src/KingSystem/Physics/Constraint/physConstraint.cpp line 21 at r2 (raw file):

    mSleepingBodies[ConstrainedType::Child] = child;

    mActiveBodies[ConstrainedType::Parent] = System::instance()->getWorldRigidBody();

same question for mActiveBodies

void Constraint::sub_7100F69FF0() {

pushToSystemIfNotSleeping?

    bool active = mFlags.isOn(Flag::Active);

I think we have a ScopedWorldLock RAII class or something like that to lock the world conditionally

---

src/KingSystem/Physics/Constraint/physConstraint.cpp line 326 at r2 (raw file):

            System::instance()->lockWorld(ContactLayerType::Entity);
        }
        mSpinLock.lock();

this might be a sead::ScopedLock as well

src/KingSystem/Physics/Constraint/physConstraint.cpp line 351 at r2 (raw file):

    if (attach_to_world &&
        mActiveBodies[ConstrainedType::Child] != System::instance()->getWorldRigidBody()) {
        if (active) {

this also smells like a RAII guard

// TODO
class ConstraintListener : public hkpConstraintListener {
    virtual ~ConstraintListener() = default;

~ConstraintListener() override = default;

(actually, do we need to override explicitly here?)
