Include

#include "Modules/ModuleInterface.h"

Syntax

class IModuleInterface

Remarks

Interface class that all module implementations should derive from. This is used to initialize a module after it's been loaded, and also to clean it up before the module is unloaded.

Destructors

Name Description

Public function Virtual

~IModuleInterface()

Even though this is an interface class we need a virtual destructor here because modules are deleted via a pointer to this interface

Functions

Name Description

Public function Virtual Const

bool

 

IsGameModule()

Returns true if this module hosts gameplay code

Public function Virtual

void

 

PostLoadCallback()

Called after the module has been reloaded

Public function Virtual

void

 

PreUnloadCallback()

Called before the module has been unloaded

Public function Virtual

void

 

ShutdownModule()

Called before the module is unloaded, right before the module object is destroyed.

Public function Virtual

void

 

StartupModule()

Called right after the module DLL has been loaded and the module object has been created Load dependent modules here, and they will be guaranteed to be available during ShutdownModule.

Public function Virtual

bool

 

SupportsAutomaticShutdown()

Override this to set whether your module would like cleanup on application shutdown

Public function Virtual

bool

 

SupportsDynamicReloading()

Override this to set whether your module is allowed to be unloaded on the fly
