Framework

Description

Manages processes across the game, forming the core of the game engine.

Introduction

In New Super Mario Bros. Wii, almost all game logic exists within individual processes. Each process represents a distinct unit of game behavior and encapsulates specific functionalities.

Nintendo refers to these processes as bases. Each type of base is defined by a profile, which determines its behaviour (is it a Goomba, or Mario, or the HUD, or the abstract concept of a world map?) and establishes its priority relative to other base types. More details about profiles can be found here.

Processes follow a hierarchical tree structure:

• Each process can have multiple siblings and children; this allows creating complex and intricate relationships between bases. An example is the Hammer Bro: all the hammers it throws are siblings of each other, and the Hammer Bro is their parent.
• The root process for all bases is the current scene; this allows the game to clean up after itself by deleting all processes when switching between scenes. Further information on this topic can be found here.

Base Implementation

All bases inherit from the fBase_c class, which defines the core elements of a process to provide common behaviour across all bases. For more detailed information, please refer to the fBase_c documentation.

The lifecycle of a base consists of multiple operations, whose behaviour can be overridden at any point. Each operation has an associated linked list, containing all bases for which said operation is scheduled for the current frame.

fBase_c defines five core operations:

• create runs immediately after construction (generally only once), and can be used to set up the base or load resources for it.
• execute serves as the base's own main loop, running every frame.
• draw offers an alternative main loop specifically for rendering code. It also runs every frame.
• delete runs immediately before destruction (generally only once), and can be used to deallocate resources or remove links to other bases.
• connect is an internal operation for process management. Bases should not override it.

The fManager_c class is responsible for managing the execution cycle of each base. It also offers various utilities for searching for bases meeting specific criteria.
