◆ loadFlags()

LoadFlags Kinoko::Field::ObjectCowFollower::loadFlags ( ) const

inlinenodiscardoverridevirtual0x806BF424

Returns a bitmask indicating which lifecycle hooks should be called for the object.

Returns: No flags set by default

In Kinoko, the only effective behavior of this bitmask is to determine whether calc() should be called. The other bits are unused.
