Kinoko::Field::ObjectChoropu Class Reference

#include <ObjectChoropu.hh>

Description

Represents the MMM and rPG monty moles.

Each mole has an associated "holl" [sic]. Moles which move around (MMM) also have an associated "ground" (the dirt trail).

◆ loadFlags()

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

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.
